OPC UA benefits for process controller

31 March 2015

Users of B&R's APROL process control system can now benefit from OPC UA. The successor of OPC, this is a cross-platform service-oriented architecture (SOA) for process control interoperability.

OPC UA makes it easier for controllers, HMI panels and SCADA systems from any manufacturer to exchange data within B&R's APROL process control system. An OPC UA server and OPC UA client are now available directly on APROL's Linux-based runtime servers to allow open, vendor-independent communication.

All APROL variables that make the OPC UA server available to other OPC UA clients via read or write ac-cess can be defined through a simple selection process. All data points that should be linked can be selected via integrated browser functionality for the OPC UA client. Important attributes such as read or write access are made available automatically.

Motor management and control units, compact OPC controllers and other devices can directly exchange all important operating, service and diagnostic data with the OPC UA client. In addition, an OPC UA server can be used to connect any number of HMI panels or SCADA systems to the APROL process control system. Communication can also be set up between APROL runtime servers. This is also possible between different APROL systems with different software versions.
