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
single master (usually either an RTU or a SCADA master station). Since the T35 maintains one set of IEC 60870-5-104
data change buffers, only one master should actively communicate with the T35 at one time. For situations where a second
master is active in a "hot standby" configuration, the UR supports a second IEC 60870-5-104 connection providing the
standby master sends only IEC 60870-5-104 Test Frame Activation messages for as long as the primary master is active.
The
NUMBER OF SOURCES IN MMENC1 LIST
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.
The
IEC ------- DEFAULT THRESHOLD
responses containing M_ME_NC_1 analog data. These settings group the UR 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 UR when any current values change by 15 A, the
IEC CURRENT DEFAULT THRESHOLD
bands. P_ME_NC_1 (Parameter of measured value, short floating point value) points can be used to change threshold val-
ues, from the default, for each individual M_ME_NC_1 analog point. Whenever power is removed and re-applied to the UR,
the default thresholds will be in effect.
The IEC 60870-5-104 and DNP protocols can not be used at the same time. When the
setting is set to "Enabled", the DNP protocol will not be operational. When this setting is changed it
TION
will not become active until power to the relay has been cycled (Off/On).
