B&R adds HART modules to X20 I/O series

These new modules are equipped with two inputs and outputs and use real-time Ethernet POWERLINK to transfer HART data supplied by sensors and actuators directly to the controller. To evaluate the data, the controller forwards information via the process bus to maintenance stations with FDT containers, for example B&R Automation Studio, PACTware or FieldCare.

In the other direction, this type of communication makes it possible to configure the HART devices. This is done with B&R's TCP/IP communication DTM, which scans the network and detects the entire hardware tree, including field devices.

The DTM server on the controller operates as a gateway that provides read/write access to all detailed information regarding HART field devices for asset monitoring. Read/Write function blocks support this access during logic processing as well.
