VisSim/OPC is an OPC
client add-on to VisSim. VisSim/OPC allows VisSim to 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 wire OPC Read and OPC
Write blocks into a diagram and then click the Go button.
You use the OPC Server block to 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.
