VisSim/OPC 
VisSim/OPC
is a VisSim add-on that provides universal
communication with any OPC (OLE for Process Control) compliant 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."
