This window displays the different fault counters of a station connected to the
Modbus Plus network.
By default, the screen proposes the default counters of the local station. It is possible to view the fault counters of a local station or of a remote station.
Note: To access the fault counters of a remote station, you must first select the number of the remote station.
the Reset Counters button resets the counters.
