NI-3101-SIG Signature Series NetLinx Integrated Controller
Master IP Local Port Send_Commands
These commands are specific to the Master and not the Controller. These commands are sent to the DPS
0:1:0 (the Master). A device must first be defined in the NetLinx programming language with values for
the Device: Port: System.
In these programming examples, <DEV> = Device. The term <D:P:S> = Device:Port:System.
Using the ID Button
The ID Button on the rear panel of the Integrated Controller is used in conjunction with the NetLinx
Studio 2.x software program to allow you to assign new Device and System numbers for the Integrated
Controller.
1.
Using NetLinx Studio 2.x, place the system in Identity (ID) Mode. ID Mode means the entire
system is put on hold while it waits for an event from any NetLinx device in the named system (for
example, pushing the ID button on the Integrated Controller). The device that generates the first
event is the identified device.
2.
Press the ID Mode button to generate an event from the Integrated Controller and assign new device
and system numbers in NetLinx Studio.
Master IP Local Port Send_Commands
Command
Description
UDPSENDTO
Set the IP and port number of
the UDP local ports
destination for sending future
packets.
This is only available for Type 2 and Type 3 Local Ports. Type 2 and Type 3 are
referring to the protocol type that is part of the IP_CLIENT_OPEN call (4th
parameter).
Type 1 is TCP.
Type 2 is UDP (standard)
Type 3 is UDP (2 way)
The NetLinx.axi defines constants for the protocol types:
CHAR IP_TCP = 1
CHAR IP_UDP = 2
CHAR IP_UDP_2WAY = 3
Syntax:
SEND_COMMAND <D:P:S>,"'UDPSENDTO-<IP or URL>:<UDP Port
Number>'"
Variables:
IP or URL = A string containing the IP Address or URL of the desired
destination.
UDP Port Number = A String containing the UDP port number of the desired
destination.
Example 1:
SEND_COMMAND 0:3:0,"'UDPSENDTO-192.168.0.1:10000'"
Any subsequent SEND_STRING to 0:3:0 are sent to the IP Address
192.168.0.1 port 10000.
Example 2:
SEND_COMMAND 0:3:0,"'UDPSENDTO-myUrl.com:15000'"
Any subsequent SEND_STRING to 0:3:0 are sent to the URL myURL.com port
15000.
Only the Device number can be changed on the Controllers using the ID
button. Port and System can not be defined.
