System controller module PPD103-B03-10-150000

The key AC 800PEC capability is high-speed control application processing, as required in power electronics, for integration into ABB’s standard ControlIT environment.

Implementation of the AC 800PEC software on three performance levels provides a superb range of control and communication functionality:

Level 1: IndustrialIT integration This level is based on the industry standard IEC 61131-3 and contains the slow-control, monitoring, operating, displaying and registering functions. The development of programs in accordance with the IEC 61131-3 standard is carried out in the Control Builder M, ABB’s IndustrialIT compatible engineering tool.

Level 2: Fast control software This level contains the fast control and protective functions with cycle times from less than 100 µs to a few milliseconds. Fast, time-critical control and I/O tasks are programmed by means of MATLAB®/Simulink® and integrated into the ControlIT environment as a Simulink I/O unit. This allows perfect interaction between the high-speed AC 800PEC core functions and the standard ControlIT software.

Level 3: High-speed I/O control This level contains highly time-critical, hardware-specific functions such as pulse-width modulators, pulse logic with associated protective functions, fast analog and binary inputs and outputs, etc. It is implemented in the FPGA (Field Programmable Gate Array) and programmed in VHDL (Very High Speed Integrated Circuit Hardware Description Language).
