Tech Note 97: How to create a connection between Wonderware Data Access Server (DA Server) and Matrikon OPC Explorer

The Wonderware Data Access Servers (in short: DA Servers) all have the ability to serve clients using three built in protocols: DDE, SuiteLink, and OPC. The Matrikon OPC Explorer is a free product from Matrikon (provider of many IO OPC Servers) and can be useful in verifying connectivity and displaying values when troubleshooting communications to a Wonderware DA

Server using OPC protocol. The way to connect to the different Wonderware DA Servers is the same, only the name of the server and the tags you are looking for may change. This document lists the steps necessary to connect to the Wonderware DA Server via OPC item naming using the Matrikon OPC Explorer (in this example we use DASMBTCP Server for Modbus Ethernet protocol).
