The Trivial File Transfer Protocol (TFTP) can be used to transfer files from the L30 over a network. The L30 operates as a
TFTP server. TFTP client software is available from various sources, including Microsoft Windows NT. The
dir.txt
file
obtained from the L30 contains a list and description of all available files (event records, oscillography, etc.).

IEC 60870-5-104 PROTOCOL
The L30 supports the IEC 60870-5-104 protocol. The L30 can be used as an IEC 60870-5-104 slave device connected to a
maximum of two masters (usually either an RTU or a SCADA master station). Since the L30 maintains two sets of IEC
60870-5-104 data change buffers, no more than two masters should actively communicate with the L30 at one time.
The
IEC ------- DEFAULT THRESHOLD
settings are used to determine when to trigger spontaneous responses containing
M_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 trigger
spontaneous 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 individual
M_ME_NC_1 analog point. Whenever power is removed and re-applied to the L30, the default thresholds are in effect.
The L30 relay does not support energy metering. As such, the
IEC ENERGY DEFAULT THRESHOLD
setting is not appli-
cable.
The IEC 60870-5-104 and DNP protocols cannot be used simultaneously. When the IEC 60870-5-104 FUNCTION
setting is set to “Enabled”, the DNP protocol does not operate. When this setting is changed, it takes effect when
power to the relay is cycled (off-to-on).
