The Comm tab of the Project Explorer organizes the worksheets that control communication with remote devices, using either direct communication drivers or other common protocols.

The folders on the Comm tab are described in the following sections:

Drivers

You can use Driver worksheets to communicate with PLCs and other hardware, using any of the hundreds of direct communication drivers that are installed with the development application.

OPC UA

You can use OPC UA worksheets to communicate with OPC servers via the new OPC Unified Architecture protocol.

TCP/IP

You can use TCP/IP worksheets to configure communication between your own project and other projects. The TCP/IP Client and TCP/IP Server modules enable two or more projects to keep their databases synchronized using the TCP/IP protocol.
