Posted 30 Oct 2017 I have a CJ1M-CPU13. It will be used for a prototype and later if successful, a better PLC fit will be employed. This system does not have the ability to drive pulses for servo control. However, will this system relay a digital signal at ~1kHz? I also need the PLC to count the pulses, reset at 1000 and start again continuously and never miss an input pulse. I see that the published transactions give <15 microsecond decision times. I would think it would be no issue. Thank you. Share this post Link to post Share on other sites
Posted 30 Oct 2017 The CJ1M is an old unit. Replacing it with CJ2M-CPU and one or two CJ2M-MD21* Pulse IO Modules is a far better option for High-Speed counters and Pulse control outputs. IMHO you are going to waste a ton of time messing with the CJ1M for your application. My 2 Cents. Share this post Link to post Share on other sites
