Dialog faults with the PLC
This type of handling groups together:
-
setting the PLC to STOP mode (or the task in which the module is configured),
-
a PLC fault,
-
a link fault between the PLC and the module.
In the above cases, the user has two options for each output:
-
maintain the output at the current value,
-
fallback to a defined value. The value must be selected between the normal display limits (0/10000) for unipolar ranges or –10000/10000 for the voltage range. By default, the module is configured in fallback to 0 mode.
Internal errors in the module
When the module has an internal error the outputs are forced to 0.
