Implementation of the AC 800PEC software on the three

performance levels provides an exceptional range of control

and communication functionality:

Level 1: System engineering (ControlIT)

ABB’s ControlIT supports all 5 IEC61131-3 programming

languages and uses ABB’s Control Builder as the program

ming tool. This is the level on which system engineers

implement functions that do not require high-speed perform

ance but demand quick and easy adaptation to a specific project.

AC 800PEC controllers can also be fully integrated into

ABB’s 800xA automation systems.

Level 2: Product & control development (MATLAB / Simulink™)

Fast closed-loop control applications are designed using

MATLAB® / Simulink®. C-code is automatically generated and

downloaded to the embedded device using Real-Time

Workshop® from MathWorks®.

Typically, it is on this level that control developers will

implement the control, the protection, the state machine and other functions.

Level 3: Communication & very fast logic (VHDL)

Extremely fast processes are programmed in VHDL. Proto

cols and some control logic requiring extremely short cycle

times are implemented on this level. The standardized tasks

are available as firmware modules and are not accessible to

the application developers.
