channel 50 for all three devices in the list.
Now let's see how the code example shown above would translate into NetLinx.

DEFINE_DEVICE
VIRTUAL1 = 33000
TP1 = 128
TP2 = 129
TP3 = 130

Note the use of the virtual device (
require that the first device in the list (the primary device) must be a virtual device. By specifying a
virtual device as the primary device in a
targeting the virtual device, but effectively operating on each physical device. Furthermore, since a
virtual device is not an actual physical device, the primary device cannot be taken off-line or removed
from the system (which avoids the potential problems that occurred in Axcess).
The virtual device's address number must be in the range of 32768 to 36863.
The example above combines the three touch panel devices:

Output changes (including level changes) sent to any device in the list will automatically be sent to all
devices in the list. For instance, the statement:

The example below illustrates the use of a device array (

the program as coming from the virtual device. Output changes, directed to the virtual device or any
device in the array, are sent to all devices in the array. Here's a syntax example:
COMBINE_DEVICES (VIRTUAL1, TP1, TP2, TP3)
In addition to virtual devices and device arrays, the NetLinx language contains several new keywords for
combine and un-combine operations:
