Ethernet communication for Ex areas

27 April 2020

Turck has introduced the first Zone 2 Ethernet gateway for its excom I/O system. This allows process data from hazardous areas to reach IT systems for analysis and evaluation at sufficient speeds and safely, via a parallel data channel – a fast and easy way of implementing condition monitoring and predictive maintenance.

The new GEN-3G multiprotocol device operates at high data rates in Profinet, Ethernet/IP or Modbus TCP networks without the need for manual intervention. 

The integrated gateway switch enables the implementation of linear topologies which can be connected easily in the network to form a ring. In addition to hardware redundancies for power supply units and gateways, excom also supports redundancy concepts such as S2 system redundancy to ensure maximum availability. excom can also provide special solutions for protocols that do not specify any native standards for redundancy. The I/O system thus offers a standard redundancy landscape for operators – irrespective of the protocol used at the particular site or plant section. 

Regardless of whether excom is used for Zone 1, 2 or a safe area users can rely on the same DTM, EDS or GSDML and the same operator logic. This reduces the training required and ensures flexible use by specialist personnel in different plant sections.
