1 Application
The remote communication can be used for different purposes, which ena-
ble better access to the information stored in the terminals. For control ter-
minals, the remote communication is also used for communication
directly between terminals (bay-to-bay communication).
The remote communication can be used with a station monitoring system
(SMS), via substation automation (SA) or a SCADA system. Normally,
SPA communication is used for SMS and SA; LON communication is
used for SA. SPA communication is also applied when using the front
communication port, but for this purpose, no special Remote communica-
tion function is required in the terminal. Only the software in the PC and a
special cable for front connection is needed.
