2.3.3 RAS function
The CPX terminal supports the RAS functions (Reliability,
Availability, Serviceability) of the field bus CC−Link.
Functions for separating slave stations:
Even if a decentral or local station fails (e.g. voltage
drop), network operation will not be impaired.
A defective slave station can be replaced whilst the net
work is in operation (the voltage of the station to be re
placed must be switched off ).
When a station is linked into the system again after a fault
has been eliminated, it is not necessary to reset the
master station.
Monitoring the communication status:
The network can be monitored by the master station dur
ing system set−up, during debugging or during mainten
ance.
