Output only via PLC

If an output is to be sent to the Event Logger only via the ChannelError() function block (FB) of the PLC, this function can be selected by writing the “log errors” CNC object. If the PLC assumes the logging function for error messages, activation normally takes place when the PLC is started.

Output via the ChannelError() FB

If errors are reported to the PLC via the PLC interface, errors can be evaluated within the PLC and reported to the Event Logger via a ChannelError() FB. Besides outputting the error, the PLC may execute other indirect reactions to a single error.

This output is identical with a TwinCAT2 output.
