Global diagnostics: 
This function can be used to permit / suppress all diagnostics messages of the module. 
(optical diagnostics signals and diagnostics in configured diagnostics modules  
are not affected) 
 
Sensor supply undervoltage: 
This function can be used to permit / suppress the diagnostics message Sensor supply 
undervoltage. (Optical diagnostics and diagnostics in configured diagnostics modules are 
not affected) 
 
Actuator supply undervoltage: 
This function can be used to permit / suppress the diagnostics message Actuator supply 
undervoltage. (optical diagnostics signals and diagnostics in configured diagnostics modules 
are not affected) 
 
Sensor short circuit at output: 
With this function, the diagnostic message sensor short circuit is allowed to output of the 
module / suppressed to the output of the module. 
(Optical diagnostics and diagnostics in configured diagnostics modules are not affected.) 
This function is valid only for channels / pins that are configured as outputs. 
As inputs configured channels / pins are not affected. 
 
The function for every individual port pin can be defined here: 
Make contact = input as normally open contact 
Break contact = input as normally closed contact 
Output = output function 
IO-Link= IO-Link function 
Make contact after configuration =  SIO mode; one IO-Link device can be configured via 
IO-Link and then moved to an SIO mode in which the 
IO-Link port pin functions as a simple switch input  
Break contact after configuration =  SIO mode, as with make contact after configuration, but 
as break contact input 
This function is a supplement to an output configuration of the respective port pin. 
For each port pin, a safe status can be predefined which is to be assumed in the event of 
a loss of bus communication.
