The purpose of this post is to demonstrate the proper Xpress Tag syntax when working with the AB ControlLogix Ethernet Communication Driver. This post assumes that the user has already configured the AB ControlLogix Ethernet Communication Driver Channel and Device within the Xpress Manager software.
This post is for Program (Local) Atomic or Logix tags defined in the Logix5000 project.
Rockwell Automation's Integrated Architecture uses tag or symbol based addressing structures. This is commonly referred to as Native Tags or Logix Tags. These differ from conventional PLC data items in that the tag name itself is the address, not the physical or logical address.
Atomic Data Types are Logix, pre-defined, non-structured data types. The following Atomic Data Types are supported by the AB ControlLogix Ethernet Communication Driver:
The Xpress Tag Syntax is as follows: Channel.Device.PROGRAM:ProgramName.LocalTagName
Example Program Tags within the Logix5000 Project:
Example Tag Addressing within the Xpress Project (Channel = CH1 / Device = D1):
The Xpress Tags can now be assigned to tools within the Xpress Project.
