B&R releases browsing function for OPC UA

July 2, 2015 - B&R releases browsing PLCopen function block that makes it easy to implement dynamic applications able to utilize data from any OPC UA server. The browsing function block allows OPC UA clients to easily determine which variables are available on a controller.

With the browsing function block, an OPC UA client can simply browse the variables available on a controller and then add them to a subscription. This was previously only possible when the name and structure of the variables were known in advance. One of many potential uses for this new function block would be to implement dynamic HMI applications that automatically adapt to the machine. Since communication takes place via OPC UA, the whole process operates independently of which vendors are used.

 

"OPC UA plays a key role in implementing fully networked factories," explains Karl Mayr, technical manager of automation software at B&R. That explains B&R's years of involvement in OPC Foundation working groups helping to advance the standard. "We're currently working on numerous other OPC UA functions that will soon be available to all users of this open communication protocol," says Mayr.
