Traction with its particularly harsh environmental conditions
is one of the most important applications of the AC 800PEC.
The controller operates through a wide temperature range
(– 40 to + 70 °C), with vibrations according 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/Os in the same
compact hardware device.
Top reliability is a must – the AC 800PEC in power
generation
Typically, excitation systems are used for generator 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concepts are no longer applicable.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 thanks to
redundant subsystems also provides increased reliability. In
the case of a problem 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 fulfilled. Should
the main controller fail, a second controller is available in
hot-standby
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
possibilities. Integrated communication ensures transparent,
plant-wide data exchange and control – from overall plant
control down to separate processes.
Use of ABB’s System 800xA with the powerful AC 800PEC
controller permits uniform automation throughout the plant,
seamlessly integrating advanced solutions into the process
control system. Strict security procedures and effective
firewalls prohibit unauthorized intrusions and ensure permanent system safety.
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 Powerlink
− ABB Drivebus (DDCS)
− Iba-PDA
− Optical Modulebus (S800)
− CANopen
