Festo – P.BE-CPX-FB37-EN – 1406NH – English
In the Festo Maintenance Tool, you will find the corresponding setting under:
CPX
“System Settings”
Tab “System Parameters”
“System start”.

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.
•
Save the required settings before replacing the bus node and restore the settings
after replacement.
4.7.2
Parameterisation of the fail-safe mode
This operating mode defines the status which digital output signals (outputs and valves) are to assume
in the event of field bus communication faults.
You can determine the status to be assumed for each output channel (output or solenoid coil or valve)
separately. The standard setting is “Reset of the output channel”.
Without parameterisation of the output channels, the following communication condition applies:
–
Input signals are transferred
–
Output signals are reset (factory setting); note that the analogue value 0 is set for analogue out-
puts.
If necessary, parameterise the required status of individual or all output channels (outputs or solenoid
coils).
