AC 800F controller

This field controller covers all major fieldbuses in process automation. Optionally, AC 800F supports redundancy. A single controller can typically support around 1,000 I/Os.

The AC 800F controller has a modular structure. The CPU is designed as a backplane to which various modules – power supply units, Ethernet and fieldbus modules – can be attached in line with the application. On the fieldbus side, modules are available for:

  • PROFIBUS-DPV1
  • FOUNDATION Fieldbus HSE
  • MODBUS (master / slave, RTU or ASCII)
  • IEC 60870-5-101, IEC 60870-5-104
  • CAN for Freelance Rack I/O

The fieldbus line and the connected field devices are entirely configured and parameterized using the Freelance Engineering Tool. No further external tools are needed for configuration.
