ABCLX Driver PLC Tag Names vs Citect Tag Addressing

Hello,

I have a large project with several AB ControlLogix PLCs and are using structured tags. There seems to be lacking documentation on how one would define a controller tag like this "Drive_E1Plus:C.JamTripEn" (BOOL type) in the address field of a variable tag (Digital Type). I know you can use the dot(.) notation in tag structures, just not sure about the colon (:). My guess at the moment is it might be problematic as thats how one would define a program tag. Does anybody have any experience doing it that way. This would be similar to reading/writing to a tag defined for an I/O module directly.

It would be nice to know the limitations of the driver now as I don't have the ability to test this yet.

Thanks,

Chris

Hi Chris,
Are you sure this is a Controller Tag? It appears to be a Program Tag due to the syntax... PROGRAM:<TaskName>
Have you tried defining the tag address as a program tag?
I've not seen ":" used as a delimeter in Controller Tags before.
Also check out TechNote 6461 for details on removing bad tags.
Kind regards
Olivier

Thanks for the reply. Yes, definitely a controller tag, we don't use program tags when interfacing with an HMI. I'm not going to setup our system this way because I can't test it before showtime.

I was going to upload a screen shot, but I keep getting errors.
