ABB PCD232 The compact controller
DESCRIPTION
ABB’s AC 800PEC controller was designed specifically with such applications in mind. The model can flexibly be adapted to handle different time domains and code can efficiently be created from Matlab/SimulinkTM models.
The processing unit inside the early AC 800PEC controllers was the PP D103. However, specifically targeting smaller systems where both space and costs are critical, ABB has produced a new controller based on the PP D104 processor – an ultra-compact device taking up less space than a credit card.
I n 2002, ABB introduced its high-end control platform, AC 800PEC, to target the important field of high-performance control.
The market required a combination of several features:
High processing power
Short cycle-time (<100 µs)
Fast time-to-market for applications
Suitable for small series Industrial grade hardware
High integration of devices
Principle of AC 800PEC
The AC 800PEC is a powerful control platform. On the hardware side, it combines the floating-point computing performance of the CPU with the highspeed flexibility of an FPGA.1) On the software side, it combines the system design capabilities of ABB’s ControlIT with the application control and simulation capabilities of MATLAB/Simulink™ (from The Mathworks®).2)
Product development
Fast closed-loop control applications are programmed using MATLAB/Simulink. C code is then generated from this using MATLAB/Simulink’s RealTime Workshop. This is compiled to an executable code using a C-Compiler and then downloaded to the controller device where the control application will start immediately after the controller is started-up. If the control application is part of a large control system requiring the presence of a ControlIT IEC61131-3 application, engineering will supervise the execution of the fast control application.

High-end controller
The first devices to be used in applications were PP D113 controllers. These are based on the PP D103 processor unit and form the high-end solution in which controllers and fastI/O are separate devices. The CPU is a PowerPC 750FX with a clock speed of up to 600 MHz.These devices currently form the controller backbone of the power electronics business.
