OPC Client licenses count

Issue

When connecting to several OPC servers, is it necessary to have several OPC Client licenses?

Product Line

TAC Vista

Environment

TAC Vista 5.x

Cause

In some cases, several counts of the same license module is required if several simultaneous sessions are in use. (Example: Workstation)

Resolution

You can connect to several OPC servers simultaneously while you just have (1) one OPC Client license.

This can be tested with the Demo license file as there is a OPC Client license module included.
