I downloaded the logic from a 5/03 plc that we do not otherwise have the original programming for. This system also has a PanelView display.
Of course, there are no comments. So I have been going through it and figuring out what is what. No problem so far. Now I realize that the tags are not in the ladder logic either. What happens if I make a change and upload that to the plc? With no tags in what I downloaded, won't the PanelView stop working correctly?
I understand that comments are stripped out of what is sent to the plc to save space, but the tags have to be in there. So why don't they download with the ladder logic? Is there a way to get them to?
