Good Afternoon,
I am currently designing an HMI application that needs a screen that shows about 20 of the latest RFID [stored in PLC] and have a running list of the previous RFID on a display [similar to an Alarm History screen]. My idea is to not have a trigger, but every time the value changes it will be listed on the screen. IF for some reason the value of the RFID is incorrect, the operator can manually select and punch in the necessary adjustment and be shown on the list. I feel like i'm brain-farting over the necessary object that is needed, so bare with me if this is a simple fix.
I have prior experience with AB/FTVS ME, but my latest project was with Omron/Yaskawa controls systems. Thus, i am pretty rusty dealing with this software. BUT WE WILL PREVAIL.
Thanks guys!
