Use the S6_PVEA_CI_J1939 function block to control a hydraulic valve.

The S6_PVEA_CI_J1939 function block uses CAN messages to control the valve actuator.

The function block contains CAN Rx symbols that receive emergency messages. The filters are set toreceive the messages from the specified NodeId.

Functional and safety interlocks are not handled in this function block.

Input data types must exactly match the indicated type for a successful compile.

Hand operation mode is not available on all PVEA-CIs.

Inputs

Inputs to the S6_PVEA_CI_J1939 function block are described.

Item Type Range Description [Unit]

Para BUS —— BUS where configuration values can be adjusted or the values can be replaced with signals routed from theapplication.

Port Port —— CAN port that receives messages from the valve and transmits commands to the valve.

Loop Tm U16 1-65535 Processing time of one program loop.[ms]

Float BOOL T/F Enable the Float function of the valve.T: Valve set to the Float position. Setpoint ignored.F: Setpoint used to control the valve.

Enable BOOL T/F Enable CAN transmissions to the valve.T: Enables CAN transmissions to the valve.F: Do not transmit commands to the valve.

Setpoint S16 -10000-10000

Sets the port flow. This value is scaled between 0 and 250 before sending it to the valve.Positive values: Extend.Negative values: Retract.0: Blocked.[0.01%]

Mode U8 1-3 The mode to which the valve is set.If the value is out of range, the mode is set to 3, emergency stop.1: Full operational.2: Hand operational.3: Emergency stop.


S6_PVEA_CI_J1939 Function Block


Function Block Parameters

Use Para BUS signals to change the operating characteristics of the S6_PVEA_CI_J1939 function block.

Input Type Range Description [Unit]

NodeId U8 128-143 CAN bus address of the valve.

SourceIdTx U8 0-255 Source address of local device.Default: 6.

DLC U8 3 or 8 Number of bytes in AVC message.Non-valid values are set to default.Default: 8.

Tx_Time U16 10-1000 Sets interval between AVC message transmissions.Default: 100.[ms]

Outputs

Outputs of the S6_PVEA_CI_J1939 function block are described.

Item Type Range Description [Unit]

Diag BUS —— BUS that provides diagnostic values for troubleshooting.

Status U16 —— Bitwise code where multiple items can be reported at a time.0x0000: Status OK.0x8008: A parameter is out of range.

Fault U16 —— Bitwise code where multiple items can be reported at a time. If a value is out of range, allCAN messages being sent keep the most recent valid data.0x0000: Status OK.0x8001: Input value too low.0x8002: Input value too high.

Error BOOL T/F Indicates an error message was received from the valve.T: The valve reported an error within the last 1.5 seconds.F: No recent error received.

State U8 0-14 Indicates the current state of the S6_PVEA_CI_J1939 valve actuator.0: Blocked.1: Extend.2: Retract.3: Float.10: Hand operation.14: Emergency stop.

Feedback S16 -10000-10000 Estimated setpoint received from the valve. This value is scaled from 125 and 225 afterthe value is received.Positive values: Extend.Negative values: Retract.0: Blocked.[0.01%]

Enabling Checkpoints

Chkpt enables the checkpoints for each Diag Bus Signal.

It is pre-connected to a constant True.

Set Chkpt to False if you do not want to use the checkpoints or if you need to free up some memory. Beaware that Fault and Status signals disappear from the service screen by setting to False.

W WarningThe programmer must implement sufficient fault management and is responsible to reach the safe stateaccording to the safety concept for the application.




Identical Function Blocks Need Different Namespace Values to Successfully Compile

If you use the same function block more than once in an application, you must change each functionblock’s namespace value to avoid compiler errors.

All function blocks contain Advanced Checkpoint with Namespace components that enable the PLUS+1®Service Tool to read block input and output values.

Some function blocks contain non-volatile memory components that store function block operatingparameters.

Both these components use memory names (“aliases”) to allocate memory. Identical memory namescause compiler errors.

The namespace value adds a unique prefix to each component name to avoid errors. Keep eachnamespace value short to save controller memory.

Change Namespace Value

To successfully compile your application, change the namespace value for function blocks that are usedmore than once in an application.

1. In the PLUS+1® GUIDE menu bar, click the Query/Change button.2. Click on the function block whose namespace you want to set to a unique value.

The Edit Page window opens.3. In the Edit Page window, enter a meaningful Namespace value.

• Namespace values are case-sensitive.• To save controller memory, use a short namespace value.

4. Press Enter.5. Repeat these steps to enter unique namespace values for other identical function blocks.

Customizable Service Screens

This function block comes with pre-made service screens that you can customize when building yourService Tool application.

The pre-made screens simplify the task of creating Service Tool applications. You can use the screens asis. Or, you can choose screen components to place in your application.




Refer to the PLUS+1® GUIDE Service Tool Design Manual (Danfoss document number L1320837) for moreinformation on how to create Service Tool screens.
