NetLinx Integrated Controllers
Setting the NetLinx Control Card Addresses (NI-4000 Only)
The 8-position CardFrame Number DIP switch, located on the rear of the Integrated Controller, sets
the starting address (the device number in the D:P:S specification) for the Control Cards installed in
the CardFrame. The address range is 1-3064. The factory default CardFrame DIP switch value = 0
(All CardFrame DIP switches in the OFF position). The formula for setting the starting address is:
(DIP switch address x 12) + Card slot Number (1-12) = Card address
For example:
DIP switch setting, 00010101: (0 + 0 + 0 + 96 + 0 + 384 + 1536) + SLOT #(ex:1) = 2017.
A card in slot number 1 would be device address 2017.
1. Set the CardFrame Number DIP switch based on the information listed in the table below.
2. Cycle power to the unit for approximately 5 seconds. This allows the unit to read the new
device number settings.
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).
Only the Device value can be set through the DIP switch settings mentioned above.
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 a device is declared in a NetLinx program with just the Device number (System and Port are
omitted), the NetLinx Compiler assumes it has a Port number of 1 and a System number of 0.
However, you should convert all existing device declarations using the D:P:S (Device:Port:System)
notation. This enables certain NetLinx specific debugging features and can help pinpoint other
possibly obscure errors.
If the cards do not appear in the Workspace window for the selected Master System
number: give the system time to detect the inserted cards (and refresh the system)
and/or cycle power to the NI-4000 unit.
