Modicon m241 System variable

Post by Marik » Fri Nov 03, 2017 6:18 pm

Good day! The object often goes out of power and turns off the controller. Is there a system variable in the Schneider that indicates that the controller has resumed its operation, or there was a power supply. At the start of the controller you need to do certain actions.
Thak you.
