5. CPX pneumatic interfaces
Module parameters:
Monitoring wire fracture channel x (only CPA and VTSA pneumatics)
Function no.
- channel 0 ... 7: 4828 + m * 64 + 6
- channel 8 ... 15: 4828 + m * 64 + 7
- channel 16 ... 23: 4828 + m * 64 + 8
- channel 24 ... 31: 4828 + m * 64 + 9
Description Determines whether Monitoring Wire Fracture for the relevant channel is active
or inactive (CPA: Channel 0 ... 21, VTSA/ISO: Channel 0 ... 31).
Monitoring wire fracture output channel ...
0 = inactive (presetting)
1 = active
Note With Monitoring Wire Fracture, a missing valve or a wire fracture (connection
fault between the pneumatic interface and the valve coil) is recognised.

Tab. 5/5: Monitoring wire fracture channel x (channel-specific)
Module parameter: Fail safe channel x
Function no. Access to these module parameters is enabled via protocol-specific functions
(see the manual for the bus node).
Description Fault mode channel x:
Fault state channel x:
Note With the aid of so-called Fail Safe parameterisation, you can specify which signal
status the outputs are to assume in the event of fieldbus communication errors
(also see CPX system manual).
