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.
