The collaboration between ODVA and the OPC Foundation will result in secure communications between devices that are a part of a CIP-enabled Industrial Control System (ICS) and other OPC UA enabled applications allowing communication between CIP devices and OPC UA devices as well as with cloud and enterprise level services.
The OPC UA companion specification will map CIP objects to the appropriate OPC UA information models and profiles and vice-versa. Sending data to and from the cloud from EtherNet/IP to OPC UA will be accomplished by providing information including discovery, identity, diagnostics, status, parameter and much more from CIP devices. Allowing critical automation information to be transferred from EtherNet/IP to OPC UA will lower the effort required to enable access from higher level systems, such as Analytics, ERP or MES. The OPC UA companion specification to CIP will ensure that data will be available to Enterprise and IT systems with proper context and semantics (i.e. meaning) for trend analysis and insight generation.
A joint working group, composed of members of ODVA and the OPC Foundation, will work to identify critical device to cloud use cases, such as tying warranty costs back to production variations, that will drive the scope of the work to be done. In parallel work to the joint development of the OPC UA companion specification to CIP, CIP and EtherNet/IP will be enhanced by ODVA SIGs, as needed, to ensure that all of the pertinent data is able to be understood by OPC UA without any additional work needed by end users.
The coordination of ODVA and the OPC Foundation will work to ensure scalability and interoperability of key device information with critical meaning across the entire enterprise. Specifically, OPC UA servers will be able to map to and expose CIP objects and will have the services to allow establishing a connection and exchanging well-formed messages between OPC UA applications and EtherNet/IP. The end goal of the joint working group is to create an OPC UA companion specification that will map CIP objects to the needed information models and profiles.
