OPC Client Connection License - System 800xA 6.1.0-1
I have a customer who wants to adjust the System 800xA licenses and it's doing long-term planning. Please, would you know how to guide me how to count the licenses needed to connect to OPC Surrogate? I know that 6.1.0-1 version doesn't count but there are prospects for the next revisions to count.
For example, for the situation below, assuming that I have only one OPC Client connected to only one server in the System, how many licenses must be purchased? One or seven licenses?
Thank you in advance.

In the output of the OPC DA Communicator Statistics operation there are two different numbers to keep apart:
- Connection client statistics (number of connections = X)
X is the number of data sources connected by the surrogate, e.g. AC 800M control network 1, PLC Connect network 2, SoftPoint network 3, General Properties, Alarm Global Properties, etc.
This number is not driving any license.
- Number of OPC Handlers: Y
Y is the number of data clients connecting to the surrogate.
This number drains an 800XA CORE:800_OPC_SRVR license seat from the .SLA file (CLS server).
