Via bit 1 of byte 0 for output data (PAA) "channel-wise pas­
sivation" can be switched on or off è Tab. 1/7.
While this function is disabled (0 = Off ), in accordance with
PROFIsafe specification and even when there is only one
channel error, the input module switches all information on
the input image into a safe status (= module-wise passiva­
tion).
– All inputs = 0
– All qualification bits = 0
Passivation in the event of a fault is based on PROFIsafe spe­
cification.
For troubleshooting
Note diagnostic messages from module in the F-Host.

If this function is enabled (1 = on) when a channel error oc­
curs, the input module switches the input information of the
affected channel pair to 0, depending on the function mode.
The input information of unaffected channel pairs does not
change and the input module remains integrated.
The input module indicates via the input image the current
channel error status to the control unit:
– All input bits relating to the channel bundle = 0
– All qualification bits relating to the channel bundle = 0
