Companion Specification
CLPA pushes OPC UA activities
The CLPA wants to simplify the implementation of Industry 4.0 applications. To this end, the CC-Link Partner Association (CLPA) and the OPC Foundation have announced an OPC UA Companion Specification for the CLPA's new 'CSP+ for Machine' technology.
The aim of the new Companion Specification is to enable entire machines to be handled like individual devices and thus simplify the acquisition of process data.
© CLPACSP+ for Machine is an extension of CLPA's existing "CSP+" (Control & Communication System Profile) specification, which enables easy network configuration and maintenance by describing all device profiles in a CC-Link IE or CC-Link network. CSP+ technology is already established and offers drag and drop network configuration using CSP+ files provided by CLPA partners. This makes it easy to create device libraries. The Companion Specification that has now been announced goes one step further by essentially enabling entire machines to be handled in this way. This means that complex systems can now be treated as if they were a single device. This reduction in complexity makes it much easier to collect important process data.
The CLPA is an international organization founded in 2000 and dedicated to the promotion and technical development of the CC-Link family of open automation networks. The key technology of the CLPA is CC-Link IE, an open Gigabit Ethernet protocol for automation.
