Name Description
I frames RX This defines the timeout in seconds from the last received I
timeout (t2) format APDU before sending acknowledgement. The t2 must be
smaller than t1. The IEC-104 standard suggests 10.
Link test This defines the interval in seconds how often the IEC-104 link is
interval (t3) tested if there is no other activity. The recommended value
depends on the criticality of the link. The IEC-104 standard
suggests 20 seconds but for pay-per-use GPRS connections the
practical value may be substantially longer.
Test link on Answer to test frame activation if the 101 link is in the
suspended suspended state.
state
Suspended This defines the time in seconds how long a connected IEC-104
timeout link can be in suspended state (STOPD) before the device
closes the connection. Using this parameter increases the
probability of detecting partially closed network connections
especially in UDP mode.
Max sequence These are the maximum sequence number used in IEC-104
number communication. The default value "0" equals to 32767 as
suggested by the IEC-104 standard.
Flush buffered Defines if buffered events are flushed on new a IEC-104
events on connection.
connection
Cause of It defines the length of IEC-104 Cause of transmission ASDU
transmission header field in bytes. The IEC-104 standard defines value "2".
length
Common This defines the length of IEC-104 Common address ASDU
address header field in bytes. The IEC-104 standard defines value "2".
length
Info object This defines the length of IEC-104 Information object address
address ASDU header field in bytes.
length
IEC-101 The IEC-101 settings define the properties of IEC-101 link layer
settings and application layer parameters as described in the IEC
60870-5-101 standard. The IEC-101 communication is carried
out between the device and a IEC-101.
Slave link The link-level address of IEC-101 slave.
address
Link address Defines the length of the IEC-101 link-level address field in
field length bytes. The link-level address of IEC-101 slave.
Event poll Event poll interval defines the IEC-101 event polling interval in
interval 0.1 second increments (class 1 or 2 poll). The events are polled
only when the IEC-104 connection is active.
Link test Link test interval defines the IEC-101 link test interval in 0.1
interval second increments. Link test is performed if there is no other
activity. The link test is performed if there is no other activity
during defined interval.
Keep link Defines that the IEC-101 link is kept always open even when
open there is no active IEC-104 connection. If the functionality is
enabled the device sends link test frames and restarts the
IEC-101 link if the test fails. The events are still not polled before
the IEC-104 connection is active. Some IEC-101 slaves require
the link to be continuously open in order to operate.
Reply header Defines the timeout in milliseconds that the device waits the
timeout reply to start from IEC-101 slave after command or request.
