Can anybody explain to me how the 'Call' function works in GE Fanuc Series 90-30???
I have to program a traffic light intersection and I was told to use the 'Call' Function in the _Main - LD
So i have to have subroutines of the Inputs, Outputs, Events, etc but I dont understand how the call function puts it all together. the help feature in the program doesnt explain it too well.
thanks in advance
also, in my subroutine ladders, why isnt the timers not working as it would in the main LD???
