Module parameters: 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: Hold last state
Fault state (presetting)
Fault state channel x: Set value
1)
Reset value
1)
(presetting)
Comment With the aid of so-called Fail-Safe parametrisation, you can specify which signal
status the bits in the control byte are to assume in the event of fieldbus commu-
nication errors (also see CPX system description).
1)
For input module CPX-P-8DE-N-…: Bit in process image outputs (see Tab. 3/10)
Tab. 3/34: Fail-safe channel x (channel-specific)
If the miniature switch of the module is set to ON, the module
provides a byte in the process image outputs (PIO)
(see Tab. 3/10).
Module parameters: Idle mode channel x
Function no. Access to these module parameters is enabled via protocol-specific functions
(see the manual for the bus node).
Description Only relevant for certain fieldbus protocols (e.g. CPX-FB11, CPX-FB32).
Idle mode channel x:
Hold last state
Idle state (presetting)
Idle state channel x: Set value
1)
Reset value
1)
(presetting)
Comment With the aid of so-called Idle Mode parametrisation, you can specify which signal
status the bits in the control byte are to assume when switching to the Idle state
(also see CPX system description).
This parameter is not available with all fieldbus protocols.
