Hello Everyone I am using a compactlogix processor and am trying to insert a tag value into a digital read out. The tag I am using is "Reservoir1PressureRaw". That is the tag i am using in the DRO value column. Why is it not reading the value. I have converted the value to string in the PLC. It is saying I have an invalid tag address. I have checked and double checked the spelling and casing. Thanks.

I found the issue. When I created the tag it was created in the main program and was not a controller tag.

You can access program scope tags by using this syntax:
PROGRAM:programname.tagname

For Program scoped tag for eg "Port_03" the following works on Logix 5000 L55
PROGRAM:Port_03.Triggertimer.ACC
