  1. The title on the diskettes for the 6201 is "PLC-2 PROG TERMINAL SW" and I believe that is the one I used years ago for the PLC2/30, but can't be certain. The 6203 diskettes have the title "PROGRAM DEVELOPMENT S/W". Does that help? I've never fully understand Allen Bradley's naming conventions. Thanks for your help, btw.
  2. Can anyone tell me what the difference is between software versions for the PLC2? One set of diskettes has a catalog number of 6201-PLC2 and the other set is cat number 6203-PLC2A. I've seen the same with PLC3 software (one set is just PLC3 and the other set is PLC3A). What does the "A" designation mean? Is PLC2A better (improved) software than the PLC2 (or vice-versa)? Thanks!
