Hi,
i have two machine using same Mitsubishi PLC FX2n-32MT Series. One of those machine is down now, so i upload the program from another machine to a new FX2n-32MT CPU & replace the broken one.
After i replace it with new CPU none of the machine function work as it should be. So i try replace the broken PLC with the other existing machine CPU & it work as it suppose too.
I can't really understand why the new CPU doesn't work but the old CPU is working perfectly??? i just ONLY remove the old CPU & everything from wiring to termination is excatly the same as previous setting.
i also can see the expansion Digital signal is working & the Analogue input & output. But still i can't make it working in the new CPU
Have anyone experience this kind of problem before??? any help will appricciated.
Thank you!
