kaptindan commented 1 year ago

So I can read a tag for a photo eye trigger which is a local tag. When i try to write to it I get a error not allowed.

PLCTAG_ERR_NOT_ALLOWED (-18) - often returned from the remote system when an operation is not permitted.

Talk to your PLC programmers about this error and they might be able to help.

Come to find out I was looking around at the PLC code and that tag was a read only. The plc programmer had no idea it got changed. lol easy fix.
