9440/15 series CPU & power modules (CPM) for Zone 2 are used for the intrinsically safe supply of power to up to 16 IS1+ I/O modules and to field circuits. RS485 with PROFIBUS DP or Modbus RTU is used for communicating with the automation system. The CPMs support system redundancy and optical rings. A DTM and process bus or service bus are used for asset management integration.
- Suitable for Modbus RTU
- Supporting system redundancy and optical rings
- Integration in plant asset management systems via ServiceBus and FDT/DTM
