The AC 800PEC adapts to any application
Seamless integration into plant control In today’s demanding market, a controller must not only deliver maximum performance but also provide transparency. In this respect, the AC 800PEC provides a large range of possibili ties. Integrated communication ensures trans parent, plant-wide data exchange and control – from overall plant control to separate processes. Use of ABB’s System 800xA with the powerful AC 800PEC controller permits uniform automa tion throughout the plant, seamlessly integrating advanced solutions into the process control sys tem. The AC 800PEC provides connectivity, using either native (built-in) or add-on functionality. Native (depending on the configuration): • MMS • Modbus TCP Slave • IEC61850 • ABB Fast Fiber Optic Link • ABB Drivebus (DDCS) • IbaPDA • Optical Modulebus (S800) • CANopen

Add-on

Well-suited to a harsh environment – the AC 800PEC Since the AC 800PEC controller is used in differ ent ABB solutions, there is a huge installed base, which enables the extraction of long-term life cycle experiences. Traction, with its particularly harsh environmen tal conditions, is one of the most important appli cations of the AC 800PEC. The controller operates through a wide tempera ture range (-40 to +70 °C), with vibrations accord ing to traction standards. The compact solution is the ideal response to the demands of restricted spaces and allows integration of the processing unit together with all the I/O’s in the same com pact hardware device. Reliability is a must – the AC 800PEC in power generation Typically, excitation systems are used for genera tor control in power plants where high reliability is the no. 1 requirement. Due to the very short process cycles, traditional redundancy concepts are no longer applicable.
The modular architecture of the AC 800PEC not only greatly reduces the complexity of the overall system, but redundant subsystems also provide increased reliability. Should a problem occur in one subsystem, the main controller switches over to the remaining subsystems, which are scaled in such a way that the overall task can still be ful filled. Should the main controller fail, a second controller is available in hot-standby. Precision for optimum quality – the AC 800PEC for industrial processes The most demanding function in a rolling mill is thickness control. By using the powerful AC 800PEC controller, a new thickness control solution for cold rolling mills has been developed based on a MIMO (Multi-Input Multi-Output) control concept. The benefit to the customer is an improvement in thickness deviation by up to 50 percent.
