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.
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.
