In this step-by-step video you'll see how communication between SNAP I/O and the A-B PLC is established and tested.

Hot Tips from PSG: Deleting Unused Tags in PAC Control

PAC Control

Opto 22's Product Support Group (PSG) develops some helpful tips as they work with customers who contact them for free product support.

Have you ever tried to delete a tag from your PAC Control strategy only to be told that you can't, because it is referenced in the strategy? But when you search for it, you can’t find where it is used.

Sometimes reference counts become inaccurate. Here's an easy way to fix them.

  • Click the Strategy Tree folder to highlight it and then press CTRL+R. PAC Control will recalculate the reference counts.
  • Choose Compile All and then save the strategy.
  • Now you can try again to delete the unused tag.

In rare cases, you may get a download error showing an undefined command related to a tag that you previously deleted from your strategy. This error may also relate to inaccurate reference counts. It may be necessary to repeat the Ctrl+R procedure several times in a row to clear this problem.

Before you delete tags in PAC Control, of course, you should make sure they are not referenced in PAC Display. Stay tuned for more tips on PAC Display in our next OptoNews.
