Before You Begin

Before reading this manual, read and understand the safety manual of the entire library (Safety Manual and Programmer Guide - General, document number AQ00000254).
Warning
Do not change parameters while the machine is driving. Before changing parameters bring the machine into a safe state to prevent harm for the operator and bystanders.
Warning
Fault detection and diagnostics must be tested with the final application which is assembled from the function blocks.

PVED_CLS_MMI Function Block

parameters, and output signals are contained inside of the bus. This signal indicates if a parameter fault is declared. It is a bitwise code, so
multiple items can be reported at a time. The following status codes are provided: 0x0000: No fault. 0x8008: At least one parameter is out of range.
This signal indicates if an input fault is declared. It is a bitwise code, so multiple items can be reported at a time. The following fault codes are provided: 0x0000: No fault. 0x8001: An input value is too low. 0x8002: An input value is too high.

Diagnostic Signals

Enter the Checkpoints page on the second level of the PVED_CLS_MMI function block to access the function block’s signals.
The page contains checkpoints on input, parameter, and output signals. Other topics in this book describe input, parameter, and output signals.

Status Logic

This topic describes how status logic is indicated for the function block. The status code indicates whether the parameters used in the function are within their valid range.
Condition Hex Binary Cause Response Correction
*
Invalid setup. 0x8008
*
Position of set bit in a 16 bit fault or status code. Bit 1 is the least significant bit. Bit 16 set to 1 indicates a standard Danfoss status code or fault code.

Fault Logic

1000
At least one parameter is out of range.
Message transmission is disabled.
Fault logic can indicate problems, causes of problems, and solutions.
Correct the out of range parameters.
Condition Hex
Input value is too low. 0x8001
Input value is too high.
*
Position of set bit in a 16 bit fault or status code. Bit 1 is the least significant bit. Bit 16 set to 1 indicates a standard Danfoss status code or fault code.

0001
0010
An input is too low. Message transmission is
disabled.
An input is too high. Message transmission is

Configure Communication for the Function Block

The following sequence demonstrates how to setup the function block for primary or redundant communication.
Note that you must route the PGN_Offset and Dest_Addr parameters out from the Parameters page.

Configure Primary Communication for Function Block

For primary communication, set the parameter Dest_Addr to 19. Set the parameter PGN_Offset to 66

Configure Redundant Communication for Function Block

For redundant communication, set the parameter Dest_Addr to 90. Set the parameter PGN_Offset to 67.

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. Be
aware that Fault and Status signals disappear from the service screen by setting to False.
Warning
The programmer must implement sufficient fault management and is responsible to reach the safe state according 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 function block’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 operating parameters.
Both these components use memory names (“aliases”) to allocate memory. Identical memory names cause compiler errors.
The namespace value adds a unique prefix to each component name to avoid errors. Keep each namespace value short to save controller memory.

PVED_CLS_MMI Function Block

Change Namespace Value

To successfully compile your application, change the namespace value for function blocks that are used more 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.
