Elements of the Connection List
A single entry in the connection list consists of the following three segments:
■ID: Identification for a connection (PLC station). The assignment of variables to certain connections is accomplished through the ID. If input or output fields are defined as part of a picture, the PLC address (tagname) must be entered with the ID (e.g., VALUE1/ID). Variable names without an ID are automatically assigned the default connection DD. An ID consists of one to two alphanumeric characters of your choosing.
