Point by Address Item ID Syntax

Point by address Item IDs allow an OPC client to explicitly refer to device registers for devices that currently communicate with a CIMPLICITY project. A CIMPLICITY project point does not necessarily need to be configured.

Note: ??Point by Address Item IDs do not appear during an OPC client browse session. These Items IDs must be manually entered in an OPC client application.

The Point by Address Item ID syntax is shown below where [ ] indicates an optional keyword. Valid keywords (required and optional) are described below.
