Supported Features
Tag Discovery
The Tag Discovery feature of this protocol facilitates the generation of the Object Linking and Embedding (OLE) for Process and Control (OPC) browse tag listing by communicating with the device through a series of attribute gathering messages. These messages inform ACM of the controller-scope tags in the ControlLogix device. User-defined atomic, structure tags (non-Micro800) and some predefined tags are further processed, and the OPC browse listing is created from this process. This process is not automatic and must be initiated by the user via command. Details on this are provided in the ControlLogix Tags guide.
