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 0- 32,767. Device 0 refers to the local Master; numbers greater than 32,767 are reserved.

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

where:

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)

NXS-NMS NetModules

The NXS-NMS NetModules (FG2009-10) accommodate one NetLinx Control Card, and connect to the NetLinx bus via ICSNet connections. The NetModules offer a simple and economical way to integrate additional functionality to control systems. FIG. 2 shows a NetModule shell and its main components.

The table below lists the NXS-NMS specifications.

NXS-NMS NetModules Specifications

Dimensions (HWD)	1.50" x 5.55" x 9.25" (3.81 cm x 14.10 cm x 23.50 cm)
ID button	Generates an event from the NetModule to allow you to assign new Device and
	System numbers, using ID mode in the NetLinx Studio software program (seeUsing
	the ID button section on page 4 for details).
Control connector	20-pin black (male) connector that connects the NetModule to external devices.
	These connectors are keyed to insure proper installation.
