3.5.1 Basic information

Festo P.BE−CPX−PN IO−EN en 0710NH
PROFINET forms the basis for comprehensive diagnostics
functions and information over your automation network,
e. g. detailed module−related and channel−related status
information and error recognition in the online mode of the
configuration software and in the PLC user program.
The following sections provide an initial view of the use of the
online diagnostics using the configuration and programming
software (see section 3.5.2) and the user−specific diagnostics
using function modules (see section 3.5.3).
Error reaction
The reaction of the CPX terminal for the following errors is
dependent on the configured reaction of the controller (of the
Master), i.e. of the PLC, the SPS or the IPC and the parameter
ised Fail Safe setting:
telegram failure
stop of the controller (of the master)
network interruption.
Depending on the parameterisation, the outputs (valves and
electric outputs) will be switched off (factory setting),
switched on or retain their status.
Further information about the Fail Safe setting can be found
in the CPX system manual P.BE−CPX−SYS−...
