The new browsing function block allows OPC UA clients to easily determine which variables are available on a controller. With this function block, an OPC UA client can simply browse the variables available on a controller and then add them to a subscription. This capability was previously only possible when the name and structure of the variables were known in advance.

It is suitable for implementing dynamic HMI applications that automatically adapt to the machine. Since communication takes place through OPC UA, the whole process operates independently of which vendors are used.
