ABB AC 800F Redundant fieldbus controller
The AC 800F controller has a modular structure. The CPU is designed as a backplane to connect different modules - power supply unit, Ethernet and fieldbus modules - according to different applications. The main supported bus protocols include:
PROFIBUS-DPV1
FOUNDATION Fieldbus HSE
MODBUS (Master/slave, RTU or ASCII)
IEC 60870-5-101, IEC 60870-5-104
CAN bus for Freelance rack-mounted I/O
The fieldbus and device connection can be configured and parameterized entirely through the Freelance engineer station software. No additional external software tools are required for the configuration process.
