ABB AC31 GRAF is a software used to program ABB Procontic CS31 PLCs

The software supports two programming languages ​​LD and FBD, although the PLCs that the software supports are no longer manufactured, but we still have to repair them sometimes on older machines.

Note: Software only supports Windows 32bit: Best on Win-XP, Windows2000 or Windows7 (32bit)
