KB-29090: OPC communication performance.

Question:

Which of the options below is the best choice?

• using an OPC Client with 20 I/O Tags linked to an OPC Server; or
• using 20 OPC Clients, each with an I/O Tag linked to an OPC server.

Solution:

We suggest that you use a single OPC Client with 20 I/O Tags, so E3 will have to create and control a just one connection.
