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 settings are used to determine when to trigger spontaneous responses containing
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
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 C30, 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 C30 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 C30 relay does not support power metering. As such, the IEC POWER DEFAULT THRESHOLD setting is not appli-
cable.
The C30 relay does not support energy metering. As such, the
IEC ENERGY DEFAULT THRESHOLD setting is not appli-
cable.
