DiagCode output

Output for diagnostic message of the function block.

Data type: WORD

Connection: If required, the signal can be connected to a standard variable of the WORD data type.

Function block-specific diagnostic and status messages are output via this output parameter and can be made available automatically to higher-level diagnostic tools.

Note
Higher-level diagnostic tools cannot confirm function block diagnostic messages. This occurs exclusively in the safety-related application program.

Whether there is an error message at the DiagCode output is indicated by the function block with Error = TRUE.

In case of status messages, Error is switched to FALSE by the function block.
All other messages are error messages, i.e., Error = TRUE.
