Micrologix Set Time from HMI

I am using an ML1100 and want to update the clock time from a C-More HMI. To do this, I have setup the ML1100 with integer words for my "TEMP" month, day, year, etc. I intended to enter these values in the HMI and press a button whichactivates a MOV or COP function to load the TEMP value to RTC:0.MON, RTC:0.YR, etc.

I have tried MOV and COP with the S:37... words and got a "Error: Word is not writeable at word level".

So, I switched to the RTC:0.YR format and get "Error:Invalid Data Type" message.

I have attached a screenshot. From the screenshot, it appears that some of the rungs are verified, and they do verify on a rung by rung basis. But when I verify the project or try to downlaod it, i get the errors. Any help is appreciated.

You must use a CPW instruction

CPW
#Nx:x
#RTC:0.MIN
1

A move fails but a CPW works fine.

Got it. Thanks!

Worked great for me also, thanks so much!

This worked for me also.
I used it from an EZPanel3 touchscreen to a MicroLogix

Thank You for the help
