I'm having problems with Modicon coils that I configured. I'm using a Modicon 984A and configured 1408 output coils. Through most of the program the software (fastrak) shows that coils 1-1408 are valid. I have one network that shows only coils 1-1377 are valid. I'm not able to use the extra coils because I get a message stating that the coils are already used. I've tried almost everything I can think of. Anybody ever run into to this or have any idea what's wrong?
