Posted 10 Jan 2020 I cannot figure out why I am getting an invalid AT?????? The Symbol is in the Variables list and when I link it to the Global Variable it auto populates, so I know it is there!! What is the issue? Share this post Link to post Share on other sites
Posted 10 Jan 2020 This can be a pain. Try deleting the variable then go to the Variable Mapping and Reset Assignment. Afterwards, Create Device Variable again. I can't seem to recreate the issue. I've seen it mostly with editing Data Types in the PLC. Share this post Link to post Share on other sites
Posted 10 Jan 2020 Yes I have done this already as this seems to happen for some unknown reason. This one tag I cannot seem to get linked up without an AT error. I have deleated, re produced, re linked, deleted and restarted software.....etc. etc........ So frustrating!! Is this a common Sysmac issue? Share this post Link to post Share on other sites
