Significance / error handling
For replacement of the bus node or
CPX terminal in case of service,
parameterisation is not created
automatically by the higher-order
system (PLC/IPC).
• Save and apply the parameterisa­
tion when the bus node is re­
placed.
The Force function is enabled.
Further information can be found in
the CPX system description
(è P.BE-CPX-SYS-...).
