TN DA106 Tips for FS Gateway OPC Item ID Prefix

insource logo large.jpg



Tech Notes that describe how to setup OPC connections to Wonderware's FS Gateway (like Wonderware Tech Note 385) often recommend adding an OPC Item ID prefix to simplify communication to individual items later.  The appropriate prefix is easy to identify when there is only one level in the hierarchy between "Root" and the tagname, as shown below.   In some cases however, there can be multiple levels, some of which can be ignored.  In these cases, use the Basket to identify the appropriate prefix (highlighted below in yellow).  Everything up to and including the colon would be included in the Item ID Prefix.
