7 Power supply of the CPX terminal
The operating and load voltage supply for the CPX terminal runs over interlinking
blocks. The interlinking blocks carry the operating and load voltage over contact
rails to the adjacent modules ( CPX system description P.BE-CPX-SYS…).
8 Start-up behaviour of the CPX terminal
If the LED “M” illuminates or flashes permanently after the system start, “System
start with saved parameterisation and saved CPX expansion” is set or “Force” is
active.
9 Note on module replacement
Note
Loss of settings
If the LED “M” of the bus node is permanently lit, parameterisation of the CPX
terminal is saved locally in the bus node. In this case, parameterisation is lost if
the bus node is replaced.
• Before replacement, secure required settings and make them again after
replacement.
10 Parameterisation
The CPX terminal and the related bus node c an be parameterised by means of the
Festo operator unit (CPX-MMI), Festo Maintenance Tool (CPX-FMT) or EtherCAT
(CoE). The CPX modules are made available in the configuration file (ESI file).
You can find the current configuration files (ESI files) and additional in-
formation on the Festo Internet page in the Support Portal
(
www.festo.com
/sp).
Further information on parameterisation and module replacement can be
found in the bus node description P.BE-CPX-FB37-...
