NI-3101-SIG Signature Series NetLinx Integrated Controller
Device:Port:System (D:P:S)
A device is any hardware component that can be connected to an AXlink or ICSNet bus. Each device must be
assigned a unique number to locate that device on the bus. The NetLinx programming language allows
numbers in the range 1-32,767 for ICSNet (255 for AXlink).
NetLinx requires a Device:Port:System (D:P:S) specification. This D:P:S triplet can be expressed as a series of
constants, variables separated by colons, or a DEV structure.
For example:
STRUCTURE DEV
{
INTEGER Number // Device number
INTEGER Port // Port on device
INTEGER System // System the device belongs to
}
The D:P:S notation is used to explicitly represent a device number, port and system. For example, 128:1:0
represents the first port on device 128 on this system. If the system and Port specifications are omitted, (e.g.
128), system 0 (indicating this system) and port 1 (the first port) is assumed. Here's the syntax:
NUMBER:PORT:SYSTEM

Configuration Port Commands
The Configuration Port commands listed in the following table can be sent directly to the Master Card using a
terminal program (i.e. Telnet). Be sure that your PC's COM port and terminal program's communication
settings match those in the table below:
Each of the NetLinx Integrated Controllers has specific port assignments:
In your terminal program, type "Help" or a question mark ("?") and <Enter> to display the Configuration Port
commands listed in the following table.
NUMBER: 16-bit integer represents the device number
PORT: 16-bit integer represents the port number (in the range 1 through the number of
ports on the Controller or device)
SYSTEM: 16-bit integer represents the system number (0 = this system)
