| Data_Type | Default_Value | Range | Unit |
|---|---|---|---|
| BOOL | - | - | - |
Output ERR indicates whether an error occurred during Function Block processing. This output always has to be considered together with output DONE. If DONE is TRUE and ERR is TRUE, an error occurred. In this case, the error number can be read at output ERNO.
An AC31 error of class 3 has occurred:
The Function Block acknowledges the error on the AC31 remote module which signalizes the error and also clears the error message on the PLC, i.e. the error flag M 255,13 is reset and LED FK3 is deactivated.
Example of a FK3 error:
A remote module is disconnected from the CS31 system bus.
An AC31 error of class 4 has occurred:
The Function Block acknowledges the error on the AC31 remote module which signalizes the error and also clears the error message on the PLC, i.e. the error flag M 255,14 is reset.
Example of a FK4 error:
A remote module signalizes an open circuit.
