# TFTP PROTOCOL
#
The Trivial File Transfer Protocol (TFTP) can be used to transfer files from the T35 over a network. The T35 operates as a
TFTP server. TFTP client software is available from various sources, including Microsoft Windows NT. The dir.txt file
obtained from the T35 contains a list and description of all available files (event records, oscillography, etc.).

The T35 supports the IEC 60870-5-104 protocol. The T35 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 T35 maintains two sets of IEC
60870-5-104 data change buffers, no more than two masters should actively communicate with the T35 at one time.

are included in the M_ME_NC_1 (measured value, short floating point) Analog points list. This allows the list to be custom-
ized to contain data for only the sources that are configured.

responses containing M_ME_NC_1 analog data. These settings group the T35 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, in order to trigger spontaneous responses from the T35 when any current values change by 15 A, the
