Type Network port
Units Port number
Value range 0 - 65000

Network idle timeout
It 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 Arctic. 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.

Network idle timeout for IEC-104 connections
Type Timeout
Units Seconds
Value range 0 – 65000
Note The network idle timeout must be longer than IEC-104 link test
interval (t3).
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.
