Hi Garry
Yes it's possible.
On the Controllogix end you must "Map PLC/SLC Messages". This takes the Controllogix tag format, MyInteger, and turns it into a format the Micrologix can understand, N7.
Then on the Micrologix you will use a Message (MSG) instruction, a 500CPU Read.
From there we need the details of what module and port you are going to communicate with the Controllogix with to give you the details for channel and path.
