Fig. 2.7.-2 Communication between a NCC (Network Control Center), a COM 500i

(Communication Gateway) and process units can be divided into upper

level communication and process communication.

Upper level communication means communication between the process units, the

COM 500i and the network control center. There can be a SYS 600 system server or

a third-party system in the network control center. The upper level communication is

usually LAN communication that uses TCP connection or an asynchronous serial

communication that uses leased telephone lines, dialed telephone lines, radio links

or power line carriers as the physical media.

Process communication is the communication between the COM 500i and the

protection and control devices connected to the physical process.

Because of electromagnetic disturbances caused by the primary electric process,

optic fibres are mostly used as communication media in the process communication.

The communication line is usually faster than the one used in the upper level

communication due to the larger quantity of data.
