i) TFTP PROTOCOL

PATH: SETTINGS PRODUCT SETUP
 TFTP PROTOCOL

The Trivial File Transfer Protocol (TFTP) can be used to transfer files from the C30 over a network. The C30 operates as a
TFTP server. TFTP client software is available from various sources, including Microsoft Windows NT. The dir.txt file
obtained from the C30 contains a list and description of all available files (event records, oscillography, etc.).
j) IEC 60870-5-104 PROTOCOL

The C30 supports the IEC 60870-5-104 protocol. The C30 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 C30 maintains two sets of IEC
60870-5-104 data change buffers, no more than two masters should actively communicate with the C30 at one time.
The
IEC ------- DEFAULT THRESHOLD
M_ME_NC_1 analog data. These settings group the C30 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 C30 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 C30, the default thresholds will be in effect.
The C30 relay does not support power metering. As such, the
cable.
