I have a Modicon 984 - 685E PLC that I am trying to start up. There is a location on the AC power terminals marked jumper. What is this jumper used for? Is it necessary for correct operation of the PLC? If anyone can send me or point me to a wiring diagram or other documentation on this product, it would be greatly appreciated.
 
There is a jumper next to the power supply connection that allows you to choose 115v AC or 240v AC supply. It needs the jumper when using 115v AC. Make sure NOT to apply 240v AC when the jumper is in.
 
I don't have answer for your request but I want ask you about this Modicon Cpu 984 which software you use for program it?
