Hi Gents,
I just finished the first stage of converting a PLC 5 system with 1 local rack + 1 remote rack to a Controllogix L61 system. I did convert the software and re mapped the IO accordingly and it's all good. However.
There are a couple of counters in the user program which simply count loaves of bread on a conveyor. Those counters count up every time a physical input is made. The input cannot do more than three on/off cycles / second.
It appears from the feedback I had from operators that these counters don't work properly as in they are missing counts.3 Hz is not a high frequency by any standard and the 1771 ASB and the DHRIO should be able to handle this easily. Not sure what should I look at.
I took a screenshot of the Controller Organizer window and attached this. I know that I didn't provide enough info but am happy to do it if someone has any idea why would I have this issue.
Thanks
