After i replace it to the new one with the same order number (6ES7 350-1AH03-0AE0) it stops working correctly i.e. there is no any errors on module, but it is not counting anymore. If i place previous module it starts count again. When I change the module I follow next procedure: - switch CPU to Stop - check Coding Key on the new module - replace module - switch CPU to Start What i'm doing wrong?
