"Confirm communication error" dialog 
The following message is displayed when PROFIsafe communication is available again after 
a communication error. 
 
Acknowledge the communication error with the enabling button or confirm the 
communication error on the fail-safe controller. 
 
If the fail-safe module detects a serious error, the fail-safe automation system outputs the 
"Fatal error" alarm. The fail-safe module must then be reset. 
 
 
Note 
This message may also occur if the Mobile Panel overheats. Check the ambient conditions.
