When I plug out any F-module from any rack the CPU goes stop-state. Regarding to user manual about S7-400FH I have to insert OB83 into program, but when I compile my safety program this OB83 disappear with message "The empty OB83 at the beginning was deleted. It will be created again if it is included in automaic block installation" (see the attached picture). How add OB83 into safety programm? Attachment F-log.jpg (72 Downloads)
