I/O solutions with Profinet redundancy

October 2019 Fieldbus & Industrial Networking

Turck’s Simple IO-Link Device Integration, SIDI for short, simplifies the handling of IO-Link. As its first fieldbus module with Profinet S2 system redundancy, the company has introduced the TBEN-L5-8IOL. This IO-Link master with IP67 protection supports the Profinet redundancy concept relevant for process automation. Through the upgrade, the block I/O module is able to establish, via a single connection, communication relations to two controllers – the primary controller and its backup. In this way, the master module integrates the host of existing IO-Link devices, such as position indicators, valve blocks, I/O hubs and sensors, in the world of high availability systems.

The device was provided with the additional function immediately after the first Profinet system redundancy certification was published. Over the course of the year, Turck will upgrade other multiprotocol devices such as the IP67 block I/O modules of the TBEN series, as well as the I/O systems for the control cabinet of the FEN20, BL20 and excom series. Profinet S2 system redundancy will thus soon become standard in Turck’s entire fieldbus portfolio.
