Hello my friends..
I have a machine with Mitsubishi FX48MT plc.
I did a simple change in program, a free input disable a existent output. I downloaded the program in cpu (eeprom key in stop and plc key too). My program downloaded correctly in cpu.
Problem: when start machine, my ladder logic not change, for example, input toggle to ON but in plc not toggle.... Its like the plc scan not execute my modification.
I tried to force a bit in my logic, but not force too.
Obs: plc is in run and machine running.
Help me please.
