VisSim/OPC – Add-On

VisSim/OPC is an OPC client add-on to VisSim. Based on proven Kepware OPC client technology, VisSim/OPC allows VisSim to connect to any OPC server, including all Kepware servers. Using VisSim/OPC, you can easily log data or run a virtual plant in VisSim for off-line tuning or operator training.

Just Click, Wire and Go

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. 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 are easily specified. You can also edit item names (including data types and initial value), time bias, percent deadband, and language ID. 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.

VisSim/OPC works with popular PLC/DCS equipment from companies including Honeywell, Emerson Process, Siemens, and Allen Bradley.

Very enthusiastic, willing to answer questions, helpful, friendly – overall very good

I had just upgraded to Windows 7, and after having Mathcad for several years I found that I could not complete the final stages of installation. After reading help files I finished up confused and really helpless, until I contacted you. THANK YOU.
