Greetings everyone,
I have one problem with my program (I am using S7 1214 DC/DC/DC). I am creating a program for measuring total time between some actions for three work shifts. Variables %MD1, %MD2 and %MD3 are used for total time. Time is measured with three TONR timers. Problem is that after the timer the variables are changing but when I monitor variables in tag table it doesn't change at all. Also, in further program these variables aren't changing. I have attached also a picture. In the main program %MD1 has a value of 32s961ms and in the tag table %MD1 has a avalue of 0ms. I can't figure it out where could be a problem.
