Setting the CardFrame's starting address

The 8-position CardFrame Number DIP switch, located on the rear of the CardFrame (FIG. 1 on page 1), 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 12-3060. The formula for setting the starting address is:

(DIP switch address x 12) + Card slot Number (1-12) = Card address

For example:

For DIP switch setting, 00010101: (0 + 0 + 0 + 0 + 96 + 0 + 384 + 1536) + SLOT #(ex:1) = 2017.

A card in slot number 7 would be device address 2023.

1.Set the CardFrame Number DIP switch based on the information listed in the table below.

Positio	1	2	3	4	5	6	7	8
n
Value	12	24	48	96	192	384	768	1536

2.Cycle power for approximately 5 seconds, so the system can read the new device number settings.

Factory default DIP switch value = 0 (zero) (All DIP switches are in the OFF position).

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)
