Application Description

Contents

You are provided with an overview of the created application and information on the used hardware and software components.

To get to know the functions of the Mobile Panel 277F IWLAN, the following automation example is used.


Figure illustrating the automation problem

Figure 1-1

Description of the automation problem

In a parcel handover station, a robot picks up parcels from a conveyor and then places them in a compartment.

For maintenance and setting work, an engineer goes into the enclosed protection zone for the robot and can then operate this robot using an HMI operator panel. The inner protection zone of the parcel handover station can be accessed through a safety door.

Outside the enclosed protection zone, it must be possible to operate also the conveyor using an HMI operator panel. The area around the conveyor is freely accessible.

In case of danger, the conveyor and the robot must be stopped from any area of the plant using an emergency stop function.

Table 2-2

Action Note

1. With the mobile panel, the engineer goes to “Area 02” (robot).

Area 02 features one transponder. The complete area includes a “zone” and an “effective range”.


3. By logging on to the “effective range” in this area, the operator can perform safety-oriented operations.


Table 2-3

Action Note

1. With the mobile panel, the engineer goes to “Area 03” (depot station).

Area 03 features one transponder. One sub-area has been defined as a “zone”. The other area has been additionally defined as an “effective range”.


3. By logging on to the “effective range” in this area, the operator can perform safety-oriented operations.

Advantage of this solution

The division of the plant into three areas ensures that the plant is well structured.

Due to the use of the Mobile Panel 277F IWLAN, radio communication provides a more cost-effective solution than cable-based communication.

Due to the spatially long extent of the automation system (conveyor), a solution using a cable-based or permanently installed system would not be advantageous.

Safety-oriented operation of the robot within the enclosed plant area is possible (moving plant part).

2.3.1 Note on software components

Engineering for IWLAN – SINEMA E

With SINEMA E (SIMATIC Network Manager Engineering), SIEMENS offers you Windows software for planning, simulating and configuring a WLAN. With the aid of this tool, you identify and eliminate possible causes of interference already in the planning phase. By simulating the radio field, you get an idea of the signal quality to be expected before installing the hardware.

Background:

The exact prediction of the propagation of a radio field depends on a large number of factors. Conducting and non-conducting objects in the transmission range can reflect, absorb, transmit or scatter radio waves.

To reliably illuminate a specific area with a radio field, there are two simple options:

1. The transmitting power of the access points is increased until they can be received at any point.

2. The access point positions are moved and reconfigured until the desired effect is achieved.

When using the first method, the actually illuminated area will almost certainly be significantly larger than actually required. This facilitates listening in by third parties and interferences can occur in neighboring WLANs.

The amount of work required for the second method is considerable and it remains questionable whether the optimum solution can be found using this approach. Particularly the probability that the installed hardware is clearly more comprehensive than the actually required hardware is very high.

The “SINEMA E” engineering tool is ideally suited to reduce this hardware.

For detailed information and examples for “SINEMA E”, please refer to the Customer Support pages: http://support.automation.siemens.com.

Use this link and you will see a film that shows you the functions and the operation of SINEMA E: http://support.automation.siemens.com/WW/view/en/37864062

Safety Evaluation Tool

The TÜV-tested online tool helps you assess safety functions of your machine quickly and reliably. The Safety Evaluation Tool for the IEC 62061 and ISO 13849-1 standards takes you directly to your goal.

Functional Mechanisms and Program Structures

Contents

This part describes the detailed functional sequences of the involved hardware and software components, the solution structures and – where useful – the specific implementation of this application.


3.1 Mobile Panel 277F IWLAN basics

3.1.1 Transponders, zones and effective ranges

Transponders

Figure 3-1

Transponders are used to form zones and effective ranges.

On each transponder, a unique ID is set using rotary coding switches. The transponder emits this ID in a lobe-shaped area.

Distance measurement is performed as follows:

The mobile panel emits signals in the current project.

The transponder responds to the signal from the mobile panel and transmits its ID to the mobile panel.

The mobile panel evaluates the ID and measures the distance to the configured transponder.

The maximum distance between transponder and mobile panel is 8 m.

The distance between mobile panel and transponder can only be measured if both devices are in the respective reception range of the other device.

Zone

Zones are used for location-dependent control of a plant area.

You can configure specific reactions in the WinCC flexible configuration. For example, you can configure a screen change when entering or exiting a zone. The “correct” plant screen for each plant area is thus displayed to the operator.

The zones are extraneous to fail-safe operation. Logon is not necessary in this area.

A zone is formed physically with transponders that are installed in the vicinity of the machine. The zones are parameterized in WinCC flexible.

The table below shows possible scenarios.

Table 3-1

Zones Note

1.

Using several transponders, you can form one zone. You can thus form larger coverages. Here the “zone area” is shown in orange.

2.

You can form one zone using several transponders (Area 01) or assign a transponder to a respective zone (Area 02 and Area 03). When orienting the transponders, it must be ensured that different zones do not overlap!

3.

In this example, Zone 01 and Zone 02 overlap. This is not permitted.

Note Zones and effective ranges can be configured independently of one another.

Effective range

An effective range is the range in which you perform fail-safe operation of plant parts, e.g. a machine, using the enabling buttons of the mobile panel.

As soon as the mobile panel detects that it is located within an effective range, the operator can log the mobile panel on to the effective range. Safe operation of the plant part separated by the effective range is possible only after successful logon.

An effective range is formed physically with transponders that are installed in the vicinity of the machine. It is parameterized in WinCC flexible.

Effective ranges and zones can be configured independently of one another.

The table below shows possible scenarios.

Table 3-2

Effective ranges Note

1.

You can form one effective range using several transponders (Area 01) or assign an effective range to a transponder (Area 02). Furthermore, you can use a transponder to form a zone and an effective range differing in “spatial extent” (Area 03). When orienting the transponders, it must be ensured that different effective ranges do not overlap! Here the “effective range” is shown in yellow. The “zone area” is shown in orange.

2.

In this example, Effective range 01 and Effective range 02 overlap. This is not permitted.

Plants without effective ranges and zones

You can also operate the Mobile Panel 277F IWLAN in a plant without effective ranges and zones. In this case, no transponders are required in the plant.

However, safe operation of plant parts using the mobile panel or automatic screen call are not possible in plants without effective ranges and zones.

Regardless of this, the emergency stop button is always active when the mobile panel is integrated in the PROFIsafe communication.

Zone ID

An ID number for each zone is stored in WinCC flexible ES. Via this zone ID, the operator panel determines the current zone in which it is located.

The ID number can be evaluated in Runtime.

Effective range ID

An ID number for each effective range is stored in WinCC flexible ES. Via this effective range ID, the operator panel determines the current effective range in which it is located.

Using this ID number, the operator logs on to an effective range.

Transponder ID

An ID number for each transponder is stored in WinCC flexible ES. Via the transponder ID, the operator panel determines its location in the plant.

This stored ID number is set on the transponder using rotary coding switches.

Enabling buttons

Figure 3-7

The enabling device consists of two enabling buttons that are mounted on both sides of the Mobile Panel 277F IWLAN (shown in yellow).

The position of the two enabling buttons is determined by electrical momentary contact switches.

The enabling button has three positions:

1. Neutral position (standard position)

2. Enable (center position)

3. Panic operation (fully pressed)

With one enabling button alone, commands for dangerous states must not be initiated. This requires a second, intentional start command using a button on the Mobile Panel 277F IWLAN.

For detailed safety notices and standards for the “enabling button”, please refer to the operating manual of the mobile panel.

3.1.4 Switch-off behavior of the Mobile Panel 277F IWLAN

The Mobile Panel 277F IWLAN features special F-program blocks which, depending on the situation in the plant, allow different switch-off behaviors.

Emergency stop

Shutdown

Local rampdown

Global rampdown

The individual terms are explained below.

!

WARNING

No triggering of safety states!

The described switch-off behavior is only triggered in the plant if the F-CPU has been programmed accordingly.

Emergency stop

To trigger the emergency stop, press the emergency stop button on the mobile panel. The emergency stop is independent of the effective ranges. When pressing the emergency stop button, the F-CPU triggers an immediate stop of the machines assigned to it.

The emergency stop button is always active when there is PROFIsafe communication between mobile panel and F-CPU, thus when the mobile panel is integrated in the PROFIsafe communication.

When there is PROFIsafe communication, the “SAFE” LED lights up.

!

WARNING

Non-functional emergency stop button!

When the mobile panel is not integrated, the emergency stop button does not function. To avoid confusion between effective and non-effective emergency stop buttons, only one integrated mobile panel must be freely accessible.

When the mobile panel is not used, it has to be stored in a locked area.

Shutdown

Shutdown is triggered when the F-CPU detects a communication error for a mobile panel that is logged on to the effective range.

Shutdown is the immediate stop of machines that belong to the effective range.

Shutdown is always specific to the effective range.

Local rampdown

Local rampdown is triggered if the mobile panel is logged on to the effective range and if it is removed from the effective range for more than 30 seconds.

Local rampdown is the defined ramp-down of the machines associated with the effective range within a defined time *).

Local rampdown is always specific to the effective range.

Global rampdown

Global rampdown is triggered if the F-CPU detects a communication error for a mobile panel that is integrated in the PROFIsafe communication.

Global rampdown is the defined ramp-down of the machines assigned in the safety program within a defined time *).

Global rampdown is independent of the effective ranges.

Using F_FB_RNG_4, the assigned effective range is managed and up to four mobile panels can be connected.


Using F_FB_RNG_16, the assigned effective range is managed and up to sixteen mobile panels can be connected.

!

WARNING

The emergency stop button is only evaluated when you call an F_FB_RNG_n in your safety program.

Always call an F_FB_RNG_n in your safety program, even if you are not using effective ranges in your plant.

You have to use one F_FB_RNG for each effective range.

Depending on the status of the mobile panels assigned to the effective range, F_FB_RNG executes the following:

Monitoring the effective range.

Supplying the panel with the data of the effective range (ID, allocation) when it is located in this range.

Logging on a panel to and logging off a panel from the effective range.

Activating “Override” mode.

Setting the outputs for

– emergency stop

– shutdown

– global rampdown

– local rampdown (depending on the status of the panels).

Note Insert the FC176: F_BO_W and FC177: F_W_BO blocks into your safety program since these blocks are called by F_FB_RNG_n. These blocks are available in the Distributed Safety F-library in the F-Application Blocks block container.

Call sequence of the F-program blocks of the mobile panel

The F-program blocks of the mobile panel must be called in the order shown below.

1. At first all F-FB161 (F_FB_MP).

2. Then all F-FB162 or F FB163 (F_FB_RNG_4) or (F_FB_RNG_16).

DB160: Data exchange (F_DB_STATES)

F_DB_STATES is used to exchange the data between F_FB_MP of the mobile panel and F_FB_RNG_n of the effective range.

Direct data exchange between the two F-FBs is not possible.

The data for up to 126 mobile panels can be stored in an F_DB_STATES. 1 word of the data block is reserved for each mobile panel.

3.1.6 Integrating and removing

Communication monitoring

In fail-safe operation, a safety program runs in the F-CPU. This safety program communicates with the mobile panel. The F-CPU monitors this communication for errors and evaluates the signals.

The terms “integrate” and “remove” refer to integrating the mobile panel into and removing the panel from the safety program of the F-CPU.

Integrating (logging on) into the safety program:

If the mobile panel is configured for the safety program, it is automatically integrated into the safety program when starting the mobile panel.

The integration is completed as soon as the “SAFE” LED lights up. The emergency stop button is active as soon as the mobile panel is integrated.

While the integration is not completed, operation with the mobile panel is not possible.

Removing (logging off) from the safety program:

This means intentionally removing the mobile panel from the safety program.

To remove the mobile panel, the operator has the following options:

The operator closes the project by selecting “Stop Runtime”.

The operator presses the ON/OFF button for more than 4 seconds.

After removing, the mobile panel switches off.

When the mobile panel is removed by the operator, no side effects such as a “global rampdown” occur. After completing the removal, the “SAFE” LED is not illuminated and the emergency stop button is no longer active.

3.2 The mobile panel in the safety-related environment

Introduction

With its features, the mobile panel offers you an almost unique combination:

Wireless HMI

Can be used for fail-safe applications

This combination offers you new application options.

This chapter shows several aspects of wireless use in fail-safe applications. At this point, these aspects are not described completely. But you are provided with basic knowledge.

Use for fail-safe applications

For fail-safe applications, the Mobile Panel 277F IWLAN is in the PROFINET network as a device. The PROFINET message frame is supplied with an additional safety message frame (PROFIsafe). The safety-related functions of the mobile panel (e.g., emergency stop) are evaluated via PROFIsafe. Via which medium (cable or radio) this information is exchanged is irrelevant from the safety aspect: If there is no safety message frame within a parameterized time, the safe state is requested.

Monitoring and response times

Depending on your application type, you have to define the maximum transit time of your fail-safe signal (present at the F-input -> processing on the F-CPU -> output at the F-output) to be able to define, for example, the safety distance to the source of danger. To calculate monitoring and response times in a fail-safe application with S7 Distributed Safety, the “S7fcotia.xls” Excel spreadsheet can be used. The maximum runtime of the F-runtime group is calculated depending on the used F-CPU. Use ID number 25412441 to download the spreadsheet and its description.

The F-function blocks associated with the mobile panel are also included in the calculation of the F-runtime group. They have not yet been considered in the current version of the “S7fcotia.xls” Excel spreadsheet. Use ID number 327097159 to download the necessary data from a table.

Note For many applications, the ramp-down time of the machine is usually considerably longer than the worst case response time of the automation system determined using the “s7fcotia” spreadsheet. In these cases, the response times of the automation system (in the range of milliseconds) can be negligible compared to the mechanical ramp-down times (in the range of seconds).

Standards

The plant owner is responsible for ensuring safety for his/her machines and the used safety system. This requires that different measures (risk assessment, determination of the safety integrity, etc.) be taken as defined in the relevant standards. In this context, the following standards have to be mentioned:

IEC 62061

ISO 13849-1:2006

The user can decide on one of the two standards.

If the user decides on an acceptance according to IEC 62061, his/her plant is characterized – with regard to the safety rating – by a max. achievable SIL (Safety Integrity Level) (e.g., SIL 1, SIL 2, SIL 3).

If the user chooses an acceptance in accordance with ISO 13849-1, his/her plant is characterized – with regard to the safety rating – by a max. achievable PL (Performance Level) (e.g., PL a, …PL e).

The mobile panel with its safety characteristics (e.g., PFH value) is included in these assessments. The “Safety Evaluation Tool” supports you when performing a final check for compliance with the SIL according to IEC 62061 or the PL in accordance with ISO 13849-1.

5.6.2 S7 program

The following sections describe the most important program blocks. The description focuses on the implementation of the F-program.

Tip:

It is recommended to open the supplied sample project to facilitate the understanding of the program structure and the described functions.

To indicate whether the described blocks are “standard blocks” or “F-blocks”, the “F-blocks” are prefixed with an “F”.

Example:

“Standard block” => FC20

“F-block” => F-FB100

In the SIMATIC Manager, F-blocks are indicated by a “yellow” frame.

Data exchange between standard program and F-program

If you want to read data from the standard program (flags or PII of standard I/O) that can be changed by the standard program or an operator control and monitoring system during runtime of an F-runtime group in the safety program, you have to use separate flags.

You must write the data from the standard program to these flags immediately before calling the F-runtime group.

In the safety program, you then have only read access to these flags.

The figure below illustrates this.

Example:

Direct data exchange between “standard program” and “F-program” is only permitted to a limited extent.

For instance, to exchange data between “standard program” and “F-program”, you have to use “flags” that are called, for example, in OB35.

1. Information on NW1: F-FB187, “F_ACK_OP”, is used for fail-safe acknowledgement. The “DB187” instance DB is used to call F-FB187. Via the “operator panel”, the values 6 and 9 are always directly assigned to the 2nd DW of the instance DB. In this case: DB187.DBW2 The evaluation of the “acknowledgement signal” of F-FB187 is always the 1st bit of the instance DB. In this case: DB187.DBX0.0 In the F-program, this “bit” is further evaluated/used. See also chapter 5.7.3, Fail-safe acknowledgement using the mobile panel. Comments on the acknowledgement: Fail-safe acknowledgement via “F_ACK_OP” is not mandatory for this application since the plant does not automatically restart after acknowledgement. The plant could thus be acknowledged via a standard signal (e.g., simple button on the panel). This example shows you how to perform fail-safe acknowledgement or intentional operation by the operator.

2. Information on NW2: F-FB161, “F_FB_MP” (mobile panel status), is called via the network. The “standard configuration” includes the description of F-FB161. See chapter 5.4.2, section “Calling and parameterizing the F-FBs for the mobile panel”.

See chapter 5.4.2, section “Calling and parameterizing the F-FBs for the mobile panel”. One F-FB162 is configured for each effective range. In networks 5 and 6 respectively, the outputs of each individual F-FB are combined to form one respective “group message” and the result is assigned to an “F-DB” (DB116). DB116 (F_DB_Data_Exchange) is a “fail-safe DB” and used to “buffer” values. Of course, the error messages can also be evaluated individually and used accordingly in the F-program.

F-FB120, F_Prog_Machine_01:

For “Machine 01”, no additional hardware was used for the application. Merely the control program, including the WinCC flexible configuration, was implemented for the application.

3. Information on NW3: Via this network, feedback circuit monitoring is performed with the aid of F-FB216. Parameter: QBAD_FIO = signal from the F-I/O/channel (4 F-DO DC24V/2A) on which the contactor for the drive is wired. For detailed information, please refer to your hardware configuration. The associated F-I/O DB is automatically generated when saving and compiling the hardware configuration. The output of the address can be found in the respective F-I/O DB under the name “QBAD” => “F-I/O DB.DBX2.1”.

5.7.2 Device-specific displays of the mobile panel

The following sections list the device-specific displays of the mobile panel that are used in the project.

Note You do not have to use the listed objects if no zones and effective ranges are provided in your plant.

However, it is recommended that at least the “Battery” and “WLAN quality” objects be used in the project.

For a detailed description of the individual device-specific displays, please refer to the following chapters:

3.1.1, Transponders, zones and effective ranges

3.1.2, Device-specific displays of the Mobile Panel 277F IWLAN

Table 5-34

No. Action Remark

1. Device-specific displays: You find the new device-specific displays in “Tools > Enhanced Objects”:

Battery



Zone quality

Zone name

WLAN quality You can configure all the objects centrally in one screen or insert the objects individually for each screen, i.e. “plant-specifically”, to have a better assignment. In Runtime, the objects always display the name or the quality for the range in which the mobile panel is currently located. For this reason, no special object properties have to be configured to the objects, for example, to display the name of an effective range.

2. Battery: Use drag & drop to insert the “Battery” object from the Tools window into your screen. In this example, the object was configured to the permanent window since it applies to the entire plant area.

In this example, the objects were configured to the respective plant screen (Screen 01 and Screen 02) to allow better orientation.

5. “Effective range quality” and “Effective range name”: If you have configured effective ranges for your plant, use drag & drop to insert the “Effective range quality” and “Effective range name” objects from the Tools window into your screen. In this example, the objects were configured to the respective plant screen (Area 02 and Area 03) to allow better operation. The “Zone name” and “Zone quality” objects were not used in “Screen 03” since the configured limits for the zone and the effective range are identical and since the objects have no operator functionality.

5.7.3 Fail-safe acknowledgement using the mobile panel

Plant states can be acknowledged using hardware keys and using the HMI operator panel.

If fail-safe acknowledgement is to be made using an HMI operator panel, the “FB187, F_ACK_OP” F-application block has to be used. This FB allows fail-safe acknowledgement from an HMI operator panel. In addition, the function of the FB can be used to perform intentional operation to exclude, for example, unintentional operation.

In this application, the function is used for:

Emergency stop acknowledgement

Release to open and close the safety door

For detailed information on the principle of operation of the FB, please refer to the STEP 7 online help.

The call of this F-FB is described in chapter 5.6.2, S7 program, in Table 5-28, no. 11.

Note Comment on the acknowledgement:

Fail-safe acknowledgement via “F_ACK_OP” is not mandatory for this application since the plant does not automatically restart after acknowledgement. The “plant” could thus be acknowledged via a standard signal (e.g., simple button on the panel).

This example shows you how to perform fail-safe acknowledgement or intentional operation by the operator.

Table 5-35

No. Action Remark

1. Acknowledgement functionality: An acknowledgement consists of two steps: Step 1: Using the first button, the value “6” is assigned to the 2nd data word of the instance DB of FB187 (F_ACK_OP). This can be done using the “Properties > Press > Calculation > SetValue” function. In this example, the value “6” is assigned to the DB187.DBW2 instance DB.

2. Step 2: Using the second button, the value “9” is assigned to the 2nd data word of the instance DB of FB 187. This can be done using the “Properties > Press > Calculation > SetValue” function. In this case, the value “9” is assigned to the DB187.DBW2 instance DB. Perform these two steps for other buttons with this functionality. Merely the relevant instance DB must be used.

3. Operation: Correct execution of the function requires that the operator initially

presses the 1st button

and the 2nd button only after one second within one minute.

If this sequence is not followed, the function will not be executed and must be repeated. In this example, the 1st button indicates that it has to be pressed for at least one second. (This ensures that the 2nd button is pressed with the respective delay.)

5.7.4 Configured screens and functions

The following sections describe the individual configured screens and the specific additional functions (scripts) that were used.

“Call_Picture” script:

Table 5-36

No. Action Remark

1. “Call_Picture” script: Using a system function, an automatic screen call can be configured on a zone. This function is always active during runtime. Another option to make an automatic screen call is to evaluate the zone ID and to use a script. The advantage is that the automatic screen call can be influenced.

2. Function: The “Call_Picture” script evaluates the “zone ID” transmitted to the mobile panels via the transponders. The respective plant screen is called depending on the evaluated “zone ID”. A “BOOL tag” is evaluated at the start of the script.

Value “0”, the following functions are executed => automatic screen change occurs.

Value “1”, the following functions are not executed => automatic screen change does not occur.

The script is called when a value of the tag is changed that has been used in the device setting for the “zone ID”. The “BOOL tag” used to evaluate whether the stored functions are executed is set or reset using a button. Thus the operator defines whether an automatic screen change is made.

6.2 Acceptance of effective ranges and transponders

Introduction

When starting a project in the plant for the first time, all effective ranges and their assigned transponders have to be tested. The result of the test is a CRC checksum that you must enter in the project. Then you have to transfer the project to the operator panel again.

Transponders that are exclusively assigned to one zone are not considered in this test.

Acceptance in the event of changes

When changing the configuration of the transponders and effective ranges in the plant, you have to adapt the configuration. Then you must accept the effective ranges and transponders again.

Requirement

In the project:

Effective ranges and transponders have been configured.

The project has been transferred to the operator panel.

In the plant:

In the plant, the transponders are installed in such a way that the effective ranges stored in the project are formed.

Batteries have been inserted into the transponders. The ID is set on the transponders that is stored in the project for these transponders.

The IDs of the effective ranges are designated in the plant.

The quality of the WLAN range is sufficient.

An indicator is installed (for example, a lamp).

2. Transponder test: After the project has started, the “Transponder test” dialog box is displayed. In “Effective ranges”, you see a list with the names of all configured effective ranges.

3. Testing effective range M02: The required values can be found in the WinCC flexible configuration. For more information, see chapter 5.7.1. Furthermore, the effective range ID and the transponder ID have been defined in chapter 5.1.2. 1. In the “Effective ranges” list, select the

first effective range (Machine_01) you want to test.

2. The right “Transponders” list displays all transponders with their respective IDs that are assigned to the effective range in the project. (In this example, a transponder with ID 200.)

3. Go to this transponder. 4. In the plant, read the ID of the selected

effective range (20) and enter this ID in the “Effective range” box.

5. In the “Transponders” box, enter the transponder ID. (In this example: 200)

6. Test the entered ID using the “Test” button.

7. When the operator panel receives the signal of the respective transponder, the transponder is considered tested. In the list, the transponder is marked with a check mark.

8. If additional transponders are located in the effective range, repeat steps 3 to 7 for all transponders assigned to this effective range.

If the transponder is not detected, check the entered values or change your position to the transponder.

7.2 Integrating the mobile panel into the IWLAN

Table 7-2

No. Action Screen

1. After you have switched on the mobile panel, the Windows CE desktop with the Loader menu is displayed after booting. The front of the mobile panel features five LEDs that display the states of mobile panel and communication (see also chapter 3.1.3). The following LEDs light up:

PWR

COM

BAT If the “COM LED” does not light up, go to the “WLAN Settings” and check the status of the WLAN settings (see chapter 5.5.1).

2. Depending on the configuration, the project starts automatically or the operator starts the project using the “Start” button on the Loader. PROFIsafe communication is established. When establishing the connection, the “Establishment of safety connection” dialog box is displayed. While this connection establishment is not completed, the mobile panel is not integrated into the CPU safety program. Operation using the mobile panel is not possible and the emergency stop button is not active. The action is canceled using the “Yes” button. You return to the Windows CE desktop user interface.

3. The mobile panel is integrated into the safety program of the F-CPU. This operation takes a certain time. The “Test enabling switches” dialog box opens. The operator is prompted to press both enabling buttons until the “Panic” position is reached. It is not necessary that both enabling buttons be pressed simultaneously. The following LEDs light up:

7.3 Removing the mobile panel from the IWLAN

Removal means the intentional removal of the operator panel from the safety program without side effects, for example a global rampdown.

The operator removes the operator panel by alternatively performing one of the following actions:

Closing the project

Switching off the operator panel

After removing the operator panel, it must be stored in a locked area.

Table 7-3

No. Action Screen

1. To stop Runtime of the mobile panel, use the “Stop Runtime” button. The button is available on the “Service Site”. Note: Always use a button with the “Stop Runtime” function in your project.

2. After you have executed the “Stop Runtime” function, the “Start removal” dialog box is displayed. Select the “Yes” button. Use the “No” button to cancel the action.

7.6 Problem solving

The following sections describe solutions to problems that may occur when commissioning.

The mobile panel does not establish communication with the PLC

Check the “WLAN Settings” of the mobile panel. -> See chapter 5.5.1.

The mobile panel does not establish a PROFISAFE connection to the PLC

Check the “WLAN Settings” of the mobile panel. -> See chapter 5.5.1.

Logon to an effective range is not possible

Check the effective range ID.

Check the transponder ID.

In the F-program, check the “F-FB162” block to see whether the associated effective range ID (RNG_ID) has been correctly assigned. This ID must match the effective range ID stored in WinCC flexible. -> See chapter 5.4.2, Table 5-13, no. 4.

Check the rotary coding switch settings of the transponders (hex value).

The F-program is not executed

Check the F-runtime group. Are the correct F-FBs called in the F-runtime group? -> F-FC1, F-FB1, DB1?

Is F-FC1 called in OB35?

Are all other configured F-program blocks called via F-FB1?

The CPU goes to “Stop” after operation on the operator panel

When diagnosing the CPU module information, the “Data corruption in the safety program…” message is displayed.

Possible cause: Probably unauthorized access or block calls in your standard or F-program.

Call the “Edit safety program” function. See chapter 5.4.2, Table 5-15.

Select the small arrow to the right of the “Compile” button. A dialog box is displayed. In this dialog box, select “Check for Accesses from the Standard User Program”. The system searches for possible unauthorized accesses and where necessary displays the relevant information.

The “Download safety program” dialog box is no longer displayed

In the SIMATIC Manager, activate the system messages in “Options > Settings > General > Deactivated system messages” by selecting the “Activate” button.

The SCALANCE W788 “home page” cannot be accessed using Internet Explorer

After parameterizing the security settings on the SCALANCE, you have to prefix “https://” in the Internet Explorer address bar (default: http://).

Appendix and References

8 Glossary

Table 8-1

Term Explanation

IWLAN IWLAN = Industrial Wireless Local Area Network The essential difference compared to a WLAN is the accurately timed transmission of trigger circuitry and data records, which is mandatory for industrial use to allow safe control of machines. The network uses a special encryption method to prevent manipulation. Standard and fail-safe communication takes place via IWLAN. Fail-safe communication complies with SIL 3 / PL e. This is enabled by PROFIsafe.

PST Primary Setup Tool

PL determination PL = “Performance Level” “Performance Level” stands for the quality of the risk reduction measures or the ability of safety-related parts of control systems to perform a safety function under foreseeable conditions and to achieve the expected risk reduction.

PL “a” (highest probability of failure)

PL “e” (lowest probability of failure)

PROFIsafe Fail-safe PROFINET bus profile for communication between safety program and F-I/O in an F-system.

PROFIsafe with SCALANCE W

PROFIsafe is a protocol extension for the PROFIBUS field bus system and the PROFINET Industrial Ethernet variant. PROFIsafe introduces features for fail-safe communication to both bus/network systems. The achieved properties include:

Protection against corrupted addresses

Protection against data loss

Guaranteed response times

RJ45 Symmetrical connector for data cables. Also known as a western connector or western plug. Widely used plug connector in telephone or ISDN technology that is used in LAN installations in the office and industrial environment.

Router Active network component that controls data traffic based on the IP address. Routers have a wide range of filter functions.

SCALANCE Scalable Performance, name of the SIMATIC NET product generation for active Industrial Ethernet network infrastructure components.

Switch A switch is a network component with essentially the same characteristics as a bridge. In contrast to bridges, however, the switch can establish multiple connections between its ports simultaneously. These connections are established dynamically and temporarily depending on the data traffic. Each connection has the full nominal bandwidth.

Term Explanation

SIL determination SIL = “Safety Integrity Level”. Discrete level (one of three possible) for the determination of the safety integrity requirements of safety-related control functions, which is assigned to the SRECS. Safety Integrity Level 3 represents the highest and Safety Integrity Level 1 the lowest safety integrity level.

SSID name In wireless networks (WLANs) according to the 802.11 standard, SSID (Service Set Identifier) refers to the freely selectable name of such a wireless network. The SSID string can be up to 32 characters long. It is configured in the access point of a WLAN and set on all clients that are to have access to it.

WLAN WLAN = Wireless Local Area Network The WLAN range is the range of the plant in which the mobile panel communicates with other communication nodes via a wireless local area network.
