This function block configures the PVED_CLS_STAT_MSG_OP for use with the PVED-CLS.
The inputs of the block are formatted to generate the message identifier that the PVED-CLS transmits.
This block receives the message and reformats the data for use in PLUS+1
®
GUIDE. For more information,
refer to PVED-CLS communication protocol.
Inputs
Enter the PVED_CLS_STAT_MSG_OP function block for an overview of its signals.
To avoid compiler errors, use only the data types specified in this table.
Parameter Type Range Unit Description
Para Bus —— —— This bus contains configuration values. You can replace these values with signals
routed from the application if desired.
CAN.Port Port —— —— Determines which CAN port to transmit data from. This variable can be found in
the CAN sub-bus if using the Main Template.

Diagnostic Signals
Enter the Checkpoints page on the second level of the PVED_CLS_STAT_MSG_OP 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
*
1000 At least one parameter is out
of range.
Status code reported. Correct the out of range
parameters.
*
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.
Configure Communication for the Function Block
The following sequence demonstrates how to setup the function block for primary or redundant
communication.
Note, you need to route the Addr parameter out from the Parameters page.
Configure Primary Communication for Function Block
For primary communication, set the parameter Addr to 19.

Danfoss | September 2019 AQ00000260en-000102 | 9
Configure Redundant Communication for Function Block
For redundant communication, set the parameter Addr to 90.
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.
W
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.

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.
