ABB PPD113 AC800PEC Control System
Large-scale power converters and drives
must be reliable, fast and precise. That
calls for a control system with outstanding
performance, such as the AC 800PEC.
But why should the same controller not
cope with slow processes, too, such as
cooling circuits, monitoring and balance of plant?
The AC 800PEC does it all: when it comes
to high-speed processes in an industrial
environment with all related ancillary
tasks, it is the ideal controller
The AC 800PEC is ABBs high-end process
IT control system, and belongs to the Control
product line.
The AC 800PEC is the optimum solution forcombining
• the high-speed control requirements of
power electronics applications
• low-speed process control tasks usually
carried out by separate PLC units.
The AC 800PEC controller is configured and
programmed using Control Builder M, ABB’s
well-established programming tool, and
® ® / Simulink with Real-Time MATLAB
® Workshop .

Key benefits
The AC 800PEC is a modular high-speed
control system. The modules are arranged
according to the
required I/O config uration and the
process.
The AC 800PEC I/O
modules are
connected
via optional
high-speed
point-to-point
connections.
The AC 800PEC supports up to
36 bi-directional fiber-optic
PowerLinks.
Performance
The AC 800PEC excels with a very high
processing speed. It provides
• Very fast analog and digital process I/Os with
a typical cycle time of 25 µs
• Fast closed-loop control and regular process
logic implemented in one controller
• Low-speed I/Os with a typical cycle time of
10 ms
• Very fast analog/digital conversion and
nominal/actual value comparison, directly on
the peripheral I/O module.
Connectivity
The AC 800PEC features outstanding ability to
communicate with other control devices:
• Two Ethernet ports for connection to a plant
control network, other processor modules,
the Control Builder M programming tool and
to the PECView service tool
• RS-232 / RS-422 serial ports for a local
process panel and/or service terminal
• Up to two on-board AnyIO ports for
ABB Communications Expansion bus (CEX)
®-S modules for all common and AnyBus
fieldbus types
• Up to 36 terminals for optical PowerLinks
and ABB S800 optical ModuleBus for cost effective, noise-immune connections to
I/O systems and power converters.
Modular configuration
The modular-design AC 800PEC comes with:
• Units mounted onto a DIN rail or equipped
for direct wall mountingThe AC 800PEC hardware
The AC 800PEC system incorporates
equipment that meets the most challenging
– and also contradictory – requirements in
process control. It includes a wide range of
I/O modules to cover all power electronics
control requirements.
The different I/O modules can be connected
to the AC 800PEC controller to cover most
automation requirements in:
• Process industry
• Power generation and distribution
• Transportation and traction.
The modular, energy-efficient design of the
AC 800PEC allows operation without forcedcooling.
The modules are mounted on standard DIN
rails and can easily be installed in distributedprocesses.
The number of directly connectable I/O sys tems is limited only by the maximum available
fiber-optic links to the processor (36 bidirec tional links).
Depending on the required performance,
single, multiple or redundant bidirectional links
are used between modules.
Each module comprises a mechanical carrier,
a base module and a configurable set of sub modules which provide the required I/O
terminals or communication interfaces.
AC 800PEC Controller PP D113
The controller comprises a low power circuit
with high reliability. The hardware can be
configured freely, depending on the process
requirements and the selected communication
with the upper control.
The AC 800PEC controller module contains the
processor, the optical interfaces to the periph eral I/O, the fieldbus, and interfaces to the
upper control:
• Base unit AC 800PEC BP (backplane with
slots for mounting the processor, the power
supply, and the optical and communication
modules)
• Processor module AC 800PEC CPU
mounted on the AC 800PEC BP. The CPU is
a fully-featured 750 MHz RISC processor with
a 64-bit IEEE Floating-Point-Unit (FPU). It is
optimized for applications with very fast
control cycles
• Two AnyIO interfaces, each consisting of
®-S slot – an AnyBus
– an additional AnyIO extension slot for an
AC 800PEC CEX interface or special
applications
• Up to 6 AC 800PEC optical modules for
fiber-optic links to various I/O modules.
