1 TaskIntroduction

Process value exchange between a head PLC and several field PLCs requiresperformant cyclic communication. This communication is for the head PLC tocollect all process values of the field devices and archive them as CSV files.

Overview of the automation taskThe figure below provides an overview of the automation task.Figure 1-1

Field PLC 1 Field PLC 2 Field PLC n

Head PLC Archiving inCSV files

Description of the automation taskThe head PLC is supposed to process the process values from the field PLCs inthe following steps: Collect process values by means of cyclic communication between head and

field PLCs Bundle process values Archive process values in CSV files

Requirements for the automation taskThe following requirements are imposed on the automation solution: Optimal and performant utilization of the available connection resources of the

head or field PLC. Easy adaptation to variable quantity structures (process values and number of

field PLCs). Applicable to IPCs with WinAC as head PLC and S7-1200/1500 as field PLCs. Process data archiving in a cycle of 1 second minimum. Process value archiving in CSV files.

SetupThis application example demonstrates the use of a communication block and dataarchiving using WinAC ODK. A SIMATIC IPC with WinAC RTX is used as head PLC. A CPU S7-1500 and two CPU S7-1200 are used as field PLCs. Data archiving is realized via the shared memory extension (SMX) interface of

WinAC ODK. A C# program reads the process values from the shared memory and archives

them in CSV files.

DescriptionThe foundation stone of this application is a communication block for datasynchronization between several field PLCs and one head PLC. For the completedescription of the communication block, please refer to the following entry:http://support.automation.siemens.com/WW/view/en/39040038This application example only describes the archiving of the collected processvalues. For the complete description of the communication between head and fieldPLCs, please refer to the above-named entry.

The task of the "Archive_Data" function block in the head PLC is to automaticallybundle the process values of the field PLCs and provide them to the Windowsoperating system via the SMX interface. A C# program reads the process valuesfrom the shared memory and stores them in CSV files. The process values arewritten to the shared memory by the STEP 7 program once per second.The C# program autonomously recognizes when new process values are written tothe shared memory by the STEP 7 program. In this case, the process values arearchived line by line in CSV files. The C# program provides a graphical userinterface. Here, archiving can be started and monitored.Figure 2-2: C# program, graphical user interface

AdvantagesThe solution presented here offers you the following advantages: Quick and easy setup of a communication solution Flexible expandability of the field PLCs Consistent archiving of process data Easy archiving operability due to supplied wizard user interface

DelimitationThis application does not include information on basic STEP 7 programming basic information on Industrial Ethernet and CPU-CPU communication

Basic knowledge of these topics is therefore assumed.

Archive_Data

STEP 7 programThe "Archive_Data" block is called every second by means of a time interrupt. Withthe help of the "C_Prog_ready" tag, the status of the C# program is checked. Whenthe C# program is ready for new data, communication with the field PLCs isstarted. Then, the data are written to the shared memory and the counter"New_Data" is incremented. This is necessary in order that the C# programrecognizes whether new data are available. If the "C_Prog_ready" tag is set to"False" when the "Archive_Data" block is called, error handling is started (seechapter 3.2.1 "Archive_Data" function block).

C# programThe C# program checks whether the "New_Data" counter has been incremented. Ifthis is not the case, it awaits the next scanning cycle. If new data are available,these are processed. The "C_Prog_ready" tag is set to "False". This is necessaryto signal to the STEP 7 program that the C# program is just processing data.(Handshake) Afterwards, the data are read from the shared memory and written toCSV files. Then, the "C_Prog_ready" tag is set to "True". This indicates that the C#program is ready for new data.

For data exchange between the STEP 7 program and the C# program, the sharedmemory interface of WinAC ODK is used. 4 kBytes of data are available each forinput and output.

Note For further information on WinAC ODK, please refer to:

http://support.automation.siemens.com/WW/view/en/12840073/133300

Archiving in CSV filesThe C# program reads the data from the shared memory and archives them inCSV files. These CSV files constitute a cyclic buffer. This buffer consists of severalCSV files which are changed as soon as a file contains 65,000 lines. When themaximum capacity of the last file has been reached, the first one is overwrittenagain. The names of the CSV files are expanded by the extension "_X", where Xstands for the number of the current file to be written.

1. Open the "Do_Communication"function block with a double-click.

-

2. Select network 3 with a right-click. Select "Insert network".A new network is inserted.

3. Drag and drop the"DATASYNC_HEAD" functionblock to the new network.

The "Call options" windowopens in which you have a newdata block created. Assign thename "IDB_04_DATASYNC"and confirm with the "OK"button.

3. Set the "REQ_4" tag in the"DB_MANAGE" data block to 1.

4. Load the project to the new fieldPLC and to the head PLC asdescribed in chapter 5.2Loading the PLCs.

-

After having executed this step, communication to the new CPU is established. Thecommunication data are stored cyclically every second in the "DB_RECV_DATA"data block.

7.3 Changing the shared memory access

In order to archive the process data of the newly added CPU, these data must alsobe written to the shared memory. The commands for that must be added in theSTEP 7 program in the head PLC and in the C# program.

7.3.1 Addresses used

In the shared memory, the following addresses have been assigned so far:Table 7-8

STEP 7 program C# program Usage

From 16348 From 0 Data exchange station 1From 17000 From 616 Data exchange station 2From 18000 From 1616 Data exchange station 3From 20000 From 3616 Data exchange date and time20477 4093 New_Data20478 4094 C_Prog_ready

Note The addresses for "New_Data" and "C_Prig_ready" are located at the end of theshared memory area. When adding new PLCs, make sure that these two bytesare not changed.

In this example, the shared memory addresses from 19000 (and 2626 respectively)are used for the new PLC.

7.3.2 Changes in the STEP 7 program

In order to archive the process data of the newly added PLC, you must expand thecode in the "Archive_Data" function block as follows:

Table 7-9


1. Open the "Archive_Data"function block under "Programblocks".

-

2. Place the cursor in the line withthe comment "Write Info fromCommunicationpartner 2".

3. Copy the lines that execute theshared memory access ofstation 2 (comment: "EndCommunication Partner 2").

-

4. Place the cursor in the line withthe comment "EndCommunication Partner 3".

5. Paste the text. -6. Adjust the commands to the

new PLC.

Start address for station 4 =19000.

The process data source is"DB_RCV_DATA".ReceiveStructure04.

7.3.3 Changes in the C# program

In order to read and archive the process data of the newly added PLCs from theshared memory, you must make the following changes in the C# program:

Table 7-10


1. Open the "MainWindow.cs" filein the Visual Studio project.

-

2. Go to the "#region VariableDefinition" area.

3. Add the following new tags.

4. Place the cursor in the "voidread_SMX(…)" function.

-

5. Copy the commands between"#region SMX READER Partner2" and "#endregion Partner 2".

6. Place the cursor below thecommand "#region SMXREADER Partner 3".

7. Paste the text. -8. Adjust the commands to the

address range of the new PLC(2616-2874).

Save the return values of theSMX functions to the tagscreated in step 3.

See screenshot in chapter 7.3.5 Screenshot of C# programexpansion

9. Place the cursor in the line withthe comment "Write Informationin CSV Output Stream".

10. Copy the"csv_writer_WriteLine(…)" lineof station 3.

11. Paste the line directly belowand change the tag names tothe ones created in step 3.

12. Place the cursor in the line withthe comment "Information forWizard Page".Expand the output by the tagscreated in step 3.

-

13. Then create a new executablefile as described in 6.1 Creatingan executable file from the C#program.
