This field controller covers all major fieldbuses in process automation.
Optionally, A 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.
Benefits
• Availability: Redundancy at all levels
• Supports different fieldbus types, even simultaneously:
• PROFIBUS-DP, up to 12 MBd
• FOUNDATION Fieldbus H1 (with LD 800HSE)
• HART
• Modbus
• Telecontrol
• CAN (for Freelance Rack I/O)
• Typically around 1.000 I/Os
• Compact, rugged design
