PATH: SETTINGS PRODUCT SETUP
 TFTP PROTOCOL

The Trivial File Transfer Protocol (TFTP) can be used to transfer files from the G60 over a network. The G60 operates as a
TFTP server. TFTP client software is available from various sources, including Microsoft Windows NT. The dir.txt file
obtained from the G60 contains a list and description of all available files (event records, oscillography, etc.).
j) IEC 60870-5-104 PROTOCOL

The G60 supports the IEC 60870-5-104 protocol. The G60 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 G60 maintains two sets of IEC
60870-5-104 data change buffers, no more than two masters should actively communicate with the G60 at one time.
The
IEC ------- DEFAULT THRESHOLD
M_ME_NC_1 analog data. These settings group the G60 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 G60 when any current values change by 15 A, the
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 G60, the default thresholds will be in effect.
The IEC 60870-5-104 and DNP protocols cannot be used simultaneously. When the
setting is set to "Enabled", the DNP protocol will not be operational. When this setting is changed it will not
NOTE
become active until power to the relay has been cycled (off-to-on).
