Serial communication

Design

An optical serial interface with LON protocol enables the terminal to be part of a Substation
Control System (SCS) and/or Substation Monitoring System (SMS). This interface is located at
the rear of the terminal. The hardware needed for applying LON communication depends on the
application, but one very central unit needed is the LON Star Coupler and optic fibres connecting
the star coupler to the terminals. To communicate with the terminals from a Personal Computer
(PC), the SMS 510, software or/and the application library LIB 520 together with MicroSCADA
is needed.

Setting parameters

Path in local HMI: Configuration/TerminalCom/LONCom/NodeInfo/AddressInfo
These parameters can only be set with the LNT, LON Network Tool. They can be viewed in the
local HMI.
