GE Multilin L30 Line Current Differential System 5-575 SETTINGS 5.2 PRODUCT SETUP5o) IEC 60870-5-104 PROTOCOLPATH: SETTINGS PRODUCT SETUP COMMUNICATIONS IEC 60870-5-104 PROTOCOLThe L30 supports the IEC 60870-5-104 protocol. This protocol is enabled when the SETTINGS PRODUCT SETUP COM-MUNICATIONS PROTOCOL setting is set to IEC 60870-5-104. The L30 can be used as an IEC 60870-5-104 slave deviceconnected to a maximum of two masters (usually either an RTU or a SCADA master station). Since the L30 maintains twosets of IEC 60870-5-104 data change buffers, no more than two masters should actively communicate with the L30 at onetime.The IEC ------- DEFAULT THRESHOLD settings are used to determine when to trigger spontaneous responses containingM_ME_NC_1 analog data. These settings group the L30 analog data into types: current, voltage, power, energy, and other.Each setting represents the default threshold value for all M_ME_NC_1 analog points of that type. For example, to triggerspontaneous responses from the L30 when any current values change by 15 A, the IEC CURRENT DEFAULT THRESHOLD set-ting should be set to 15. Note that these settings are the default values of the deadbands. P_ME_NC_1 (parameter of mea-sured value, short floating point value) points can be used to change threshold values, from the default, for each individualM_ME_NC_1 analog point. Whenever power is removed and re-applied to the L30, the default thresholds are in effect.The IEC REDUNDANCY setting decides whether multiple client connections are accepted or not. If redundancy is set to Yes,two simultaneous connections can be active at any given time.IEC TCP PORT NUMBER: When set to 0, the change takes effect when the L30 is restarted.IEC COMMON ADDRESS OF ASDU: The change takes effect when the L30 is restarted.IEC CYCLIC DATA PERIOD: The change takes effect when the L30 is restarted.Do not set more than one protocol to the same TCP/UDP port number, as this results in unreliable operation ofthose protocols.The L30 relay does not support energy metering. As such, the IEC ENERGY DEFAULT THRESHOLD setting is not appli-cable.
