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:
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.
The AC 800F controller distributes process and diagnostic data from four fieldbus gateways. If required, it can also work with various fieldbus types – and this is, of course, in addition to the usual tasks of a “conventional” controller. Thanks to its compact and sturdy design, the AC 800F is suitable both for installation in the control room and for use in junction boxes directly in the field.
Availability: Redundancy at all levels
Supports different fieldbus types, even simultaneously:
PROFIBUS-DP, up to 12 MBd
FOUNDATION Fieldbus H1 (with LD 800HSE)
CAN (for Freelance Rack I/O)
Typically around 1,000 I/Os
Compact, rugged design
The AC 800F hardware
The AC 800F has a modular structure. The CPU is designed as a backplane to which various modules – power supply units, Ethernet or fieldbus modules – can be attached in line with the application. On the fieldbus side, modules for PROFIBUS-DPV1, FOUNDATION Fieldbus HSE, MODBUS (master/slave, RTU or ASCII), IEC 608 0-5-101 and CAN for Freelance Rack I/O are available. The fieldbus line and the connected PROFIBUS slaves are entirely configured and parameterized using the Control Builder F engineering tool. No further external tools are needed for configuration. PROFIBUS slaves can be integrated into the system using a GSD) file or FDT/DTM). In the case of FOUNDATION Fieldbus, configuration takes place using CFF or DD files. This allows fieldbus parameterization even without connected field devices.
Also Freelance Rack I/O can be connected to the AC 800F, in which case a CAN module is used. This allows you to operate five I/O racks, with a total of around 1000 I/Os, for each AC 800F. The I/O racks are equipped with a link module and up to nine I/O modules and can be mounted separately at a distance of up to 400 m from the AC 800F.
