 NetLinx NetModules

NetLinx Control Cards and NetModules 

NetLinx Control Cards can be installed in the NXF CardFrame, NI-4000, or 
NetModules. The NetModules provide enclosures for the Control Cards. 
The product name of the generic NetModule shell is NXS-NMS. For more 
information on the NetModules and NetLinx Control Cards, refer to the 

NetLinx CardFrame, Control Cards, and NetModules

NetModules (NXS-NMS)

NetModules accommodate a 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. 1 shows a NetModule shell and its main components.   

ID Button:

The ID Button on the rear panel of the NetModules is used in conjunction 
with the NetLinx Studio software program to allow you to assign new Device 
and System numbers for the Module.

1.

Using NetLinx Studio, place the system in Identity (ID) Mode. ID Mode 
means that 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 a Module). The device generating the first event is the 
device that is identified.

2.

Press the ID Mode button to generate an event from the Module to 
allow you to assign new Device and System numbers in NetLinx 
Studio.

+12 VDC Power Supply Connectors:

Two parallel male 2-pin (green) parallel connectors for 12 VDC power. 

Connection to either power connector provides loop through power to 
the other connector.

Connecting an external power source disconnects the NetModule from 

the power supplied via ICSNet.

Control Card Connectors:

To install a Control Card into a NetModule:

1.

Remove the magnetic front faceplate/viewing window from the Net-
Module. 

2.

Align the edge of the Control Card with the slot Control Card slot on 
the front of the NetModule. Slide the card into the enclosure and press 
until you feel the Card seat in the connector.

3.

Put the magnetic faceplate back on the NetModule.

Compatible NetLinx Control Cards:

The NetModules accepts the following NetLinx Control Cards: 

  

  

Device:Port:System (D:P:S)

A device is any hardware component that can be connected to an AXLink 
or NetLinx (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 0-32,000. Device 0 (zero) refers to the master, and 
numbers greater than 32,000 are reserved.
NetLinx requires a Device:Port:System (D:P:S) specification. 
This D:P:S triplet can be expressed as series of constants, variables 
separated by colons, or as a DEV structure. For example:

STRUCTURE DEV

{

INTEGER Number  // Device number

INTEGER Port    // Port on device

INTEGER System  // System 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 the device TP on 
this system. 
If the Port and System numbers are omitted, Port #1 and System #0 (zero) 
are assumed. Here's a syntax sample:

NUMBER:PORT:SYSTEM

where:

NUMBER: 6-bit integer representing the device number

PORT: 6-bit integer representing the port number (in the range 1 

through the number of ports on the Controller or device)

SYSTEM: 6-bit integer representing the system number (0 = this 

system)

NetLinx Device Number Conventions:

NXS modules typically occupy the device number range from 5001 to 5999.

Mounting Modules Into an Equipment Rack:

The NetLinx Modules can be rack-mounted using an optional AC-RK Rack 
Mount Kit.
