Ovation DCS is a large-scale automation control system developed by Emerson in the United States, with a communication rate of 100MB per second, a processing capacity of 200000 real-time information points per second, a network length of 200 km, and a maximum of 1000 nodes. The operator station uses DELL company's commercial computers, and the switch uses CISCO products. This DCS is highly favored by industrial controllers due to its support for live plugging, simplicity, strong functionality, convenient configuration, and easy wiring. CCPP adopts redundant Ovation DCS VWesteringhouse Westinghouse 3.3.1, with a C/S structure, registration code authorization, and communication protocol using Ethernet TCP/IP. Install the English version of Windows 2003 Server on the server and Windows XP on the client.
