Path Segment Error (Invalid Tag Name)

(1/1)

gusterminator:
I created a new routine.  I added a JSR on Main page to link to the new routine.  Everything works In the new routine....program wise.  I then added a new Form to Advanced HMI.  I added the EitherNetIP communication driver.  When ever I link something from my new Form I get this error "Path Segment Error (Invalid Tag Name)"  I have checked spelling......copy paste exact name.....nothing works from the new routine on my new form page.  If I link to something from the Main routine from the new Form it works.

any ideas what might be causing this???

Thanks,

Maybe your tag was created as a "Program Scope" tag rather than a "Controller Scope"?

If it is program scoped, it can still be read, you just have to change the format a bit:

PROGRAM:ProgramName.TagName

You would have to replace "ProgramName" with the name of the program that the tag was created in and replace "TagName" with the name of your tag.

What PLC. This very much matters.

I did not read between the lines, but figured it out.  Only replace "ProgramName" and replace "TagName" as noted.  Leave the word PROGRAM: (or Program:) as is.

Here is an example that worked for me connecting to AB PLC:
"Program:RFID_Controllers.RFID_Max_Read[0]"

Maybe this example will help someone else, or me - sometime later.
