General
The OPC Unified Architecture standard makes it possible to exchange information among devices from multiple vendors. It is platform independent and connects the industry to IT. You can sit at your local PC or handheld device and exchange information with any device that is modelled on OPC UA.
The Anybus CompactCom implements an OPC UA server which models the Anybus CompactCom as a device in its address space using the OPC UA Device model. The modelled device is of type CompactCom40DeviceType which is a subtype of the OPC UA DeviceType. It is possible for the user to change certain parameters e.g. the name of the device and its device type, to make the application manufacturer specific. See CompactCom 40 Device Type Information Model.
It is also possible to model and download an application defined information model based on e.g. an existing Companion specification. See Application Defined Information Model.
OPC UA is disabled by default. It has to be enabled during startup of the Anybus CompactCom. This is done by modifying attribute #1 (OPC UA Model), in the OPC UA Object (E3h), instance #1. Set the attribute to 1 for the CompactCom40DeviceType and 2 for the downloaded application defined information model.
