Read out diagnostic data more easily

Pepperl+Fuchs launches the LB Profinet gateway, enabling full access to all connected HART devices in addition to the conventional Profinet functionality.

In practice, HART auxiliary variables are therefore available to the user as secondary measured values in addition to the process variables. Furthermore, the diagnostic data of the field devices can be read out via HART-IP - this significantly increases transparency and system availability. The gateway also offers flexibility, as different protocols can run over the same connection cable. Up to 80 field devices can be connected to a fully occupied remote I/O system and communicate without any time delay. The gateway has an intelligent redundancy concept: an integrated switch guarantees the function of the network at all times based on the Medium Redundancy Protocol (MRP). If a line fails, the ring network is reconfigured to route data packets via the alternative route. The device status and other diagnostic data can be read at a glance via RGB LEDs on a large display.
