VisSim/OPC
Introduction
VisSim/OPC is a VisSim addon that lets you connect to any OPC server.
Using VisSim/OPC, you can easily log data or run a virtual plant in VisSim for offline tuning or operator training. To exchange data between VisSim and any OPC server, you simply insert OPC Read and OPC Write blocks, wire them to the diagram, and click "Go".
The OPC Server block allows you to easily establish a connection with the OPC server. You can create connections to as many OPC servers as you require. The OPC Read and OPC Write blocks let you read data from and write data to an OPC server. Update rates and data exchange modes can be quickly modified through the dialog boxes for these blocks. You can also edit item names (including data types and initial value), time bias, percent deadband, and language ID.
VisSim/OPC works with popular PLC/DCS equipment from companies like Honeywell, Emerson Process, Siemens, Allen Bradley etc.
VisSim/OPC allows me to easily exchange data between plant controllers and process models developed in VisSim for off-line tuning and controller development. The product works well and is easy to set up.
