  1. 1756-HSC vs 1771-VHSC

    We have just replaced a PLC-5, RS Logix 5 PLC with Control Logix I'm having encoder count issues with the new HSC, I have it configured and wired similar the old 1771-VHSC However, now my encoders only count up or down NOT BOTH?? I have the channel on the HSC set for Encoder 4X, with a preset and a roll over. ANY IDEAS? THANKS !!
  2. 1756-HSC vs 1771-VHSC

    Yes, I've searched every word in the BTW, I don't see any differences in the old vs new. We have since replaced the encoders with AB Ethernet encoders. However I would still be interested in why?!
