Good day all,
PLC: RSLogix/Studio 5000 using Ladder Logic
I've been toying around with the idea of capturing the previous value of a tag inside of my PLC, but I cannot seem to get started with the best way of coding this. I was hoping I could get some help with this.
I would like the tag Previous_Tag to be able to capture the value regardless whether the number increases or decreases. Also, the value may change in an inconsistent manner/pattern at times (I.E. 1 ->4, 4->11).
Thank you for your help.
