Tab. 117: Example of output data for reading out the most recent entry in a malfunction list
A copy of the actual malfunction list is created at the moment in which channel 31 is called. As long
as channel 31 is not exited, this copy will not change. This prevents the content changing between
the individual queries (number of entries, upload of individual entries) and the received values from
becoming inconsistent.
If inactive errors are acknowledged via the WebConfig interface, while the transfer mode channel 31
is active on the PLC side the display on the WebConfig interface will differ from the data received from
the PLC.
