ABB PM802F 3BDH000002R1 AC 800F controller device configuration

Description

When AC 700F is equipped with the Profibus Master module CM 772F it can communicate
over a single Profibus DP segment with several remote I/O stations. Some configurations are
shown in the following figures. They describe different ways how to feed the PDP22-FBP fieldbus plug, which is an active element, with power.
Figure 1 shows the first variant, where the power is fed-in with the PDA11 adapter cable. The
twisted-pair cable has to be connected to an 24 V DC power supply. The M12 connector of
the cable is directly connected close to the controller using the fieldbus plug. The adapter
cable has four wires, two more than a standard Profibus cable. The additional wires are used
to feed the external power to both fieldbus pluges shown in Figure 1.
The Profibus DP segment has to be terminated at the end with an PDR11-FBP terminator.

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 for PROFIBUS-DPV1, FOUNDATION Fieldbus
HSE, MODBUS (master / slave, RTU or ASCII), IEC 60870-5-101 and CAN for Freelance Rack
I/O are available.
The fieldbus line and the connected field devices are entirely configured and parameterized using
the engineering tool Freelance. No further external tools are needed for configuration. Fieldbus
and device configuration can be performed offline without connection to the field devices. In case
of Profibus, field devices or slaves can be integrated into the system using device specific GSD1
files or DTMs2. If for a certain device no DTM is available, generic GSD files of Profibus slaves
can be used instead. Together with S900 remote I/O, HART variables are cyclically available as
process data.
In the case of FOUNDATION Fieldbus, configuration takes place using specific CFF3 or DD4
files. Field devices are connected to H1 links, which in turn are connected via LD 800HSE linking devices to the high-speed HSE subnet.
Even a single AC 800F controller can be connected to both buses, Profibus and FOUNDATION
Fieldbus at the same time. This makes it very convenient to run loops of an FF application using
„control in the field“ technology, while at the same time gathering fast binary data via high-speed
Profibus using remote I/Os.
