The OPC Basis not too long ago fashioned a brand new working group to develop an I/O System Profile for OPC UA and the extensions for the sphere stage, named OPC UA FX (Area eXchange). The group reportedly goals to create a standardized profile for I/O units utilized in industrial automation purposes, permitting for seamless interoperability between controllers, reminiscent of PLC and DCS methods, and distant I/O units, together with modular I/Os.

The brand new OPC UA I/O Working Group is being established by the OPC Basis, underneath the management of the Area Stage Communications (FLC) Initiative. Participation within the working group is open to members of the OPC Basis. Producers from the method and manufacturing facility automation industries are represented inside this working group to make sure that I/O units might be simply built-in into totally different automation methods and environments.

Greater than 50 consultants from greater than 30 member corporations of the OPC Basis signed up for the kick-off assembly of the brand new working group which was held on December 11, 2023. Rosh Sreedharan from Rockwell Automation and Mark Nixon from Emerson had been confirmed as preliminary working group chairs.

“Extending the OPC UA Framework with an I/O System Profile is vital to make sure cross-vendor interoperability and customary semantics for the Controller-to-System use circumstances in manufacturing facility and course of automation, whereas on the identical time supporting OPC UA as a totally scalable know-how from the sensor throughout all ranges to MES / ERP and in addition to the cloud,” said Peter Lutz, Director FLC Initiative at OPC Basis.

So as to obtain inter-vendor interoperability of I/O units, the working group will add to the UAFX base specs the definition of interfaces and behaviours that are typical for I/O units. The brand new I/O machine profile will use PubSub and might be mixed with totally different underlying communication protocols (e.g. UDP/IP or Uncooked Ethernet) and bodily layers (e.g. Ethernet-APL) to help all related use circumstances in discrete and course of manufacturing, together with security I/Os based mostly on OPC UA Security and deterministic knowledge trade based mostly on Ethernet Time-Delicate Networking (TSN), the place acceptable. The working group can even reportedly attempt to handle overlap with different info fashions already launched or underneath growth. Examples embrace the fashions for movement and instrumentation.
