Hey Guys,
Does anyone have experience with the ABB AC500 PLC? I want to know how it compares to the more popular Allen Bradley ControlLogix PLCs or Siemens S7-400H Redundant PLCs in terms of reliability, maintenance, programming and ease of use. I am asking this because the ABB AC500 is cheaper by almost $28,000 than A-B ControlLogix & $18,000 than Siemens S7-400H for the system i am planning to use (61 DI, 41 DO, 4 AI, redundant controllers). are A-B & Siemens PLCs worth that extra money?
Thanks,
