5.6.1 Use IP List
N
O
(0) or Y
ES
(1)
This parameter specifies if the IP address of the host connected to the system
will be validated. If the parameter is set to N
O
(0), any host may connect to the
unit. If the parameter is set to Y
ES
(1), only hosts in the IP list will be permitted to
connect to the unit.
5.6.2 Override StartDT
N
O
(0) or Y
ES
(1)
This parameter is used when testing the module with a simulator or with a Client
unit that does not meet the IEC 60870-5-104 specification. After the Client
connects to the module, it will send a STARTDT.ACT U-format message to the
module to permit the module to start sending data. If the Client does not support
this requirement, set the parameter to Y
ES
(1). Set the parameter to N
O
(0) if the
Client sends the STARTDT.ACT message.
Note: This parameter must be set to N
O
(0) if you wish to use the redundant Clients feature.
5.6.3 Clear Queue on Close
N
O
(0) or Y
ES
(1)
Use this command to define whether the module will store the unacknowledged
buffers in the unit after the connection is closed. If the specification is to be
followed, set this parameter to N
O
(0) and the packets will be resent after a
connection is made. If you want to flush the packets after the connection is
closed, set this parameter to Y
ES
(1) (this is not according to the IEC 60870-5-
104 specification).
5.6.4 t0 Connection Timeout
1
to 1000, default value = 30
This is a timeout value, in seconds, to determine if a connection has been lost
with the remote Client. If no traffic from the remote client is received for the
period of time specified by this parameter, the currently open server IP socket
connection will be closed. The connection can be re-established by the remote
Client by opening a new connection.
5.6.5 t1 Timeout Set Value
1 to 255
This is the timeout of send or test ASDUs in seconds. After a packet is sent from
the unit, the Client must acknowledge the packet within this time interval or else
the unit will close the connection.
