Hi, I am trying to transfer a PLC program from a FX2N to a FX1N and to do so I have to change some contacts in the program that are in the range of over 1500 for the auxiliary relays M (since it's outside the range for the FX1N and I couldn't write it to the PLC).
The problem is that they are all contacts that I cannot find the coils for. I am not sure if they are the input of the sensors or if the program will be still be able to function correctly if I replace the PLC even if it's not the same contact number since they don't have a coil?
Is it possible that the HMI attached to the PLC receives the signal from the sensors and then sends them to the PLC giving the contacts numbers that I have change?
