The Series 9441/12 CPU for Zone 1 is used to communicate with the automation system via PROFINET, Modbus TCP or EtherNet/IPTM. The connection is established by means of an optically inherently safe "op is" fibre optic, which can be connected and disconnected in hazardous areas. IS1+ and connected HART devices are integrated in asset management systems using a DTM.
- Suitable for "op is" 100 Mbps Ethernet with PROFINET, Modbus TCP or EtherNet/IPTM
- Redundant connection possible with Modbus TCP
- CPU in Zone 1 can be replaced without having to disconnect the power supply (i.e. hot-swapped)
