IP Address (if applicable)
This is the IP address to which the control sends all unsolicited responses (if enabled).
It is also used to verify whether a master is one of the registered masters (both DNP
and IP addresses must match). An IP address of 0.0.0.0 is represented as blank on the
IntelliLink software screen. When using serial communications, specify the DNP master
address and the serial port to be used. All other IP related parameters are ignored. The
listening port for incoming TCP connections and UDP packets is hard coded at 20,000.
Entering an IP Address
The IP address entry has been simplified, follow these steps to enter an IP address:
STEP 1.
Click and highlight the character in the first cell.
STEP 2.
Type one to three characters as needed.
STEP 3.
Hit the space bar to advance to the next field. Advancing in this fashion
automatically highlights the characters in the next field.
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 configured
for a TCP/IP connection, and select UDP if the SCADA master is configured 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.
Port Number
This setting is ignored unless the
TCP
or
UDP
option has been selected for the master
station
Port Code
setting. This port is the outgoing port for unsolicited TCP or UDP
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 configuring 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
setting. Select the
Add-On
or
Native
setting. The
Not TCP
option is a placeholder and is not applicable. Select the
Add-On
setting for IntelliRupter
fault interrupters because they do not have a native Ethernet port.
For IntelliRupter fault interrupters, the control module catalog number SDA-4540R3
has Ethernet I and Ethernet 2 ports. Ethernet 1 is the Native port and Ethernet 2 is the
Add-On port. Either port can be configured for an IP address.
