Description
Handling of the unrecognized
messages. When this is false,
unrecognized messages are
ignored. When this is true,
unrecognized messages sent
by the slave are forwarded to
an object with an address
defined by the Unrecognized
Messages Address property.
The length of the cause of
transmission field in an IEC
60870-5-101 message in oct-
ets.
The length of the information
object address in octets.
The maximum length of trans-
mitted message in octets.
The length of the polling
address in octets.
The length of the station
address in octets.
The hour transmission method
of the events to the master.
When this is false, the master
gets the year, date, and hour
from the slave as hourly clock
synchronization (ASDU 103).
When this is true, the master
adds the year, date, and hour
from its internal clock to the
events. Minutes and seconds
should be provided in time-
tagged events by the slave.
Time synchronization interval
in seconds.
Time synchronization offset in
tenth of milliseconds. This can
be used to fine-tune the time
synchronization accuracy,
when there is a fixed delay
caused by the used communic-
ation network.
