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 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, to trigger
spontaneous responses from the T35 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 T35, 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.
When the IEC port number is set to 0, the change takes effect when the T35 is restarted.
Do not set more than one protocol to the same TCP/UDP port number, as this results in unreliable operation of
those protocols.
The T35 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).

ADDRESSES
The UR can specify a maximum of five clients for its IEC 104 connections. These are IP addresses for the controllers to
which the UR can connect.
A maximum of two simultaneous connections are supported at any given time.
