The 9441/12 series CPU for Zone 1 and Class I, Div. 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 Zone 1 and Class I, Div.1
IS1+ and connected HART devices are integrated into asset management systems using a DTM.
- Suitable for op is 100 Mbit/s Ethernet with PROFINET, Modbus TCP or EtherNet/IPTM
- Redundant operation with Modbus TCP possible
- CPU can be hot swapped in Zone 1 and Class I, Div. 1
