We have a machine with an IMC-120 servo system that we need to try to get up and running. We're machine resellers; we'll give it a fair shot to get it up and running using the existing controls. If that's not possible in a reasonable amount of time and expense or the customer insists, we'll swap out the control system for modern hardware.
The IMC-120 module (1771-HSN) has a red System LED on. The IMC-120 installation manual (1771-6.5.45) says it "indicates module faults detected by software (i.e. PLC communications fault, memory error, broken wire, lithium battery too low etc.)" Does anyone have any further insight to offer? As I mentioned on another thread...

...the PLC5/10 had lost its program so we typed in a paper listing of the program and it included a JSR to U:3 but we don't have a listing for the U:3 subroutine. I assume that held the code for controlling the IMC-120 (among other things). Is this the likely cause of the red System LED?
It seems I need AB's ODS offline development software to program the module. Does anyone know if this is available anywhere?
For completeness, the system also comprises a 1771-HT termination panel and a 1391B-AA22 servo drive.
