4. Digital CPX multi I/O modules
Module parameters: Fail safe channel x
Function no. Access to these module parameters is made via protocol−specific functions
(see the manual for the bus node).
Description Fault mode channel x: Hold last state
Fault state channel x:
Note With the aid of the so−called Fail safe parameterizing, you can specify the signal
status which the outputs are to assume in the event of field bus communication
faults (see also CPX system manual).
Tab. 4/10: Fail safe channel x (channel−specific)
Module parameters: Idle mode channel x
Function no. Access to these module parameters is made via protocol−specific functions
(see the manual for the bus node).
Description Only relevant for certain field bus protocols
Idle mode channel x:
Idle state channel x:
Note With the aid of the so−called Idle mode parameterization, you can determine the
signal status which the outputs are to assume when switching is made to the
Idle state (see also CPX system manual).
This parameter is not available with all field bus protocols.
