Diagnostics integrated in Modicon M340, Modicon M580, Premium and Quantum automation platforms
Presentation
The diagnostics offer for Modicon M340, M580, Premium and Quantum platforms is
based on the following three components:
b System diagnostics
b DFB and EFB diagnostic function blocks (for system and application diagnostics)
b Error message display system, called viewers, supplied as a standard component
of Magelis XBT terminals, Vijeo Citect supervisory software and Unity Pro setup
software
System diagnostics
The system diagnostics for the Modicon M340, M580, Premium and Quantum
platforms support the monitoring of system bits/words, I/O modules and activity times
(minimum/maximum) of SFC steps. By simply choosing the relevant option during
application conguration, any event will generate time-stamped messages logged in
the diagnostic buffer of the PLC.
These events are displayed automatically in a diagnostics viewer
(1) without requiring
any additional programming.
With Unity Pro integrated diagnostics, this function can be used to perform rst level
diagnostics of the elements in the conguration, up to and including each I/O module
channel.
