Posted 19 Dec 2015 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 !! Share this post Link to post Share on other sites
Posted 21 Dec 2015 What are the encoder count issues you are experiencing? Have you documented the PLC-5 configuration words to determine the exact previous configuration? Share this post Link to post Share on other sites
Posted 23 Dec 2015 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?! Share this post Link to post Share on other sites
