ABB UNITROL® 5000 System Communications

ABB UNITROL® 5000 System Communications
Today, simple and user-friendly commissioning and operation are as important as the easy integration in higher hierarchical control systems. UNITROL 5000 offers several types of human machine interfaces, and also various bus couplers for higher hierarchical control systems.

Communication with the system

The service panel SPA is connected to the system via an RS485 interface. The four-line display shows system functions, system parameters, measured values, alarms etc. in clear text form. The excita tion system can be controlled with the push-buttons. The control panel LCP (optional for smaller excitation systems) can be used for local or remote control is connected via the ARCnet bus. The LCP is for the control of the system, the display of actual values and events.

Optical link for commissioning and service

The UNITROL 5000 system can be con nected to a PC with the CMT software installed via an optical link. This ensures a fast and secure communication with the excitation system

Integration in higher hierarchical control systems

Communication with higher hierarchical control systems is possible with the appropriate bus coupler that is connected to the DDCS interface (via an optical link). The following standard protocols are supported for control and data transfer: • MODBUS • MODBUS+ • Profibus.

Remote diagnostics

If the excitation system is equipped with the optional remote diagnostics function, ABB service personnel can, with the customer’s permission, access the system via the internet. For further details, please refer to the last page of this brochure
