RTU Sampling
Configuration of sampling of input values by the RTU.
The
DinBox RTU M4
can perform automatically some sampling tasks to sent events to a
IEC60870-5-104 master. The following sampling tasks are supported:
Supply Voltage
When this threshold detection sampling is enabled, the internal power supply
voltage [5V nominal] will be measured after the configured number of seconds
and an event with ASDU TI36 with IOA 400 (default) will be transmitted if the
voltage is below the minimum value and when the signal comes above the
default value again.
Mains Disconnect
When this option is enabled, if the mains voltage is disconnected (detected
via an internal optocoupler circuit) an event with ASDU TI30 (value “1”) with
IOA 528 (default) will be transmitted.
If the mains detection is reestablished an event with ASDU TI30 (value “0”)
with IOA 528 (default) will be transmitted.
RSSI
When this threshold detection sampling is enabled, the RSSI (GSM signal
strength) value will be measured after the configured number of seconds and an
event with ASDU TI36 with IOA 408 (default) will be transmitted if the RSSI is
below the minimum value and when the signal comes above the default value
again.
