Switch Control Setup
Entering an IP Address
IP address entry has been simplied, follow these steps:
STEP 1. Click and highlight the character in the rst cell.
STEP 2. Type one to three characters as needed.
STEP 3. Hit the space bar to advance to the next eld. Advancing in this fashion
automatically highlights the characters in the next eld.
STEP 4. Repeat typing, followed by the space bar until entry is complete.
To revert to the IP address value presently configured in the control memory, press
the <Esc> key or click the Reset button in the tool bar.
Port Code
This is the port through which unsolicited report-by-exception DNP frames to the master
station are sent. Port A (serial) is the default. Select TCP if the SCADA master is congured
for a TCP/IP connection, and select UDP if the SCADA master is congured for UDP/IP.
The port code also is used to check that an incoming message is from a registered
master. In addition to the DNP address and IP address (if TCP or UDP is used), the port
code must also match.
TCP Port
This setting is ignored unless the TCP option has been selected for the master station
port. This port is the outgoing port for unsolicited messages that occur when there isn’t
an active session with the master. (Range: 1,024-65,535; Step: 1; Default: 20,000)
Note: UDP uses the fixed port 20,000 as source and destination.
TCP Interface
When conguring the IP address (if applicable), set this to the Ethernet port associated
with that IP address. This setting is ignored unless the TCP option has been selected
for the master station port. Select the Add-On or Native setting. The Not TCP option
is a placeholder and is not applicable.
TCP Interface FAILOVER
This is the interface selected for the Failover IP address. As above, select the Add-On
setting for IntelliRupter fault interrupters.
Unsolicited Responses
When enabled (the default), the control sends a message to the master station when new
event data are available based on the Unsolicited Transmit Delay Event Count setting
and the Unsolicited Transmit Delay Time setting. A master station DNP address and
master station port code or master station IP address must be entered. Enabling this
feature may add signicant trafc to the communication network.
Unsolicited Response Mode
Select Normal (default) or 5800 V2 Mode setting. The Normal mode requires that
the master station acknowledge an initial empty (null) unsolicited message at control
restart. The SCADA master must send a command to enable unsolicited reporting.
If acknowledgment of the initial empty unsolicited message is not received, the
control continues to resend these messages at the congured retry interval until an
acknowledgment is received. The 5800 V2 Mode setting is a non-standard mode that
bypasses the initial empty unsolicited messages and the requirement for the master
station to enable unsolicited reporting with a SCADA command. It simply starts sending
unsolicited responses as events occur, provided that the Unsolicited Responses
parameter is enabled.
The 5800 V2 Mode setting may require restarting the control unless the control is
presently sending unsolicited responses in the Normal mode or a remote command
to enable unsolicited responses can be sent to the control. To restart the control after
