Tags in RSLogix when I add them to my project are coming up #COM. I have existing tags which work, so communication to the PLC is ok.
The tags that are bad are in the ladder program only.

There are 2 types of tags in RSLogix: program and controller tags. The controller tags can be addressed just by the tag name that appears in RSLogix.
For the program tags, in the address of the tag you need program:mainprogram in front of the tagname in order to resolve the address.
Also in the address, use "{}" and "/" in place of "[]" and "."

Please refer to the ABCLX help file for more information. (Citect\Bin\Abclx.chm)
