Use HW flow
control
HW flow control mechanism (RTS/CTS) on IEC-101 serial
communication. Note: The HW handshaking is available only on
RS-232 mode.
No, Yes
Network
settings
The Network settings define the general TCP/IP networking
properties between the device and the IEC-104 master.
Network
protocol
Network protocol defines the network transmission layer protocol
(either TCP or UDP) used on IEC-104 network communication.
The IEC-104 standard protocol uses TCP, but for reliable slow
speed packet switched networks (for example Mobitex), the
UDP protocol can be used to minimize the packets transmitted
over network. Note: The IEC-104 standard specifies only TCP
protocol.

Network idle
timeout
Network idle timeout defines the idle timeout of the network
connection in seconds. If there is no network data received
during the specified interval, the connection is closed by the
device. This parameter is required in order to detect partially
closed connections and release the resources for new
connections especially if the New connection priority parameter
is disabled. Value “0” disables the network idle timeout
detection. The network idle timeout must be longer than IEC-104
link test interval (t3).
0...65000
New
connection
priority
It defines the action when a new connection request arrives
while a connection is already active. If the set value is ”No”, the
new connection is rejected. If the set value is ”Yes”, the present
connection is terminated and the new connection is accepted. It
is recommendable to set this value to “Yes” in normal
configurations having only one IEC-104 master.
No, Yes
Max clients Max clients defines the maximun number of connections
(redundancy group).

IEC-104
settings
The IEC-104 settings define the properties of IEC-104 link layer
and application layer parameters as described in the IEC
60870-5-104 standard. The IEC-104 communication is carried
out between the device and the IEC-104 master over the TCP/IP
network.
TX window
size (k)
TX window size defines the maximum number of I format APDU
packets the device may send before requiring the IEC-104
master to acknowledge them. If there are
k unacknowledged
frames sent the device stops polling IEC-101 slave for events
until acknowledgement is received. The
k must be always less
than the maximum sequence number defined below. The
IEC-104 standard suggests
k to be 12.
1...20
RX window
size (w)
RX window size defines the maximum number of I format APDU
packets the device may receive before sending
acknowledgement to the IEC-104 master. The
w should not
exceed two-thirds of TX window size
k. The IEC-104 standard
suggests
w to be 8.
1...20
I frames TX
timeout (t1)
It defines the timeout in seconds the device waits for
acknowledgement from IEC-104 master after sending last I
format APDU or control frame (e.g. link test). If no
acknowledgement is received during the defined time the device
will close the network connection and the IEC-101 link. The t1
must be longer than the network round-trip-time. The IEC-104
standard suggests 15 seconds.
