Tech Note 106: Interfacing InTouch HMI to N-TRON OPC Server

N-Tron series of managed and un-managed switches are bundled with an OPC-DA (v1.X) server that can collect network and switch diagnostics. These diagnostics can be interfaced into the InTouch HMI so that diagnostics can be visualized, historized or alarmed. This tech note describes the process of integrating these switch diagnostics via Wonderware OPCLink.

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

Tech Note 76: Configuring the DDESuitelink Client Object in the ArchestrA IDE

This tech note details the procedure used to configure DDE (Data Dynamic Exchange) and Wonderware Suitelink client connections using Wonderware Application Server and the ArchestrA IDE (Integrated Development Environment). The DDESuiteLinkClient object available in Archestra IDE provides a client connection to DDE or Suitelink servers so that data can be read and written to external data sources such as a PLC (Programmable Logic Controller).

This tech note consists of three parts:

  • Part 1 - details the process of configuring and deploying a new instance of the $DDESuiteLinkClient template for communication with a data source
  • Part 2 - details testing of the

Tech Note 74: How to configure Wonderware DASABCIP for unsolicited message handling

For certain classes of critical alarms, it may be best to allow the PLC (Programmable Logic Controller) to notify the data clients immediately rather than waiting for a polling interval to update the alarm point at the HMI (Human Machine Interface). For this type of event, certain Allen Bradley PLCs (i.e. ControlLogix family) have the ability to send unsolicited messages to clients. This tech note provides the procedure to configure a Wonderware DASABCIP topic to accept unsolicited messages.

Tech Note 71: How to bridge DDE (Dynamic Data Exchange) protocol to Suitelink protocol using Wonderware FactorySuite Gateway

With the release of newer operating systems from Microsoft, such as Windows Vista, support for NetDDE (Network Dynamic Data Exchange) is being discontinued. This poses a problem for legacy I/O communication servers which are DDE based, as newer clients may not be able to directly communicate with them.

A workaround exists, which will translate DDE to Suitelink protocol and give legacy DDE servers the ability to communicate with the most recent client operating systems. This workaround involves configuring Wonderware FactorySuite Gateway (FS Gateway) on the DDE IO Server node for protocol translation.

FS Gateway is capable of translating DDE, Suitelink,
