OPC 30142 PROFI-RemoteIO


The OPC UA for Remote IO Information Model is based on two RIO application profiles: Remote IO for Factory Automation and Remote IO for Process Automation.
It allows OPC UA Clients to access the IO data of PN Submodules. The Information Model is divided into a PROFINET aspect offering detailed Telegram information and a functional aspect modelling Process Values as part of RIO Channel Objects. The two aspects offer different access paths for Clients and are connected by dedicated References to allow navigating to the preferred representation from either aspect.
