Combining and Un-Combining Levels

To approach setting up level combine and un-combine operations in NetLinx, let's first look at the way
that level combine operations are done in the Axcess language. The example below illustrates how an
Axcess program would combine three Touch Panel levels to act as one.
The code shown in the Axcess example will not work in NetLinx, due to
incompatibilities between the languages (i.e. Axcess does not allow virtual devices,
which are required for Combine/Uncombine operations in NetLinx).
DEFINE_DEVICE
TP1 = 128
TP2 = 129
TP3 = 130
DEFINE_CONNECT_LEVEL
(TP1,1, TP2,1, TP3,1)
,
TP1 TP2
on any of the three devices, Axcess sees the level coming only from the first device in the list (
Likewise, any level change sent to any device in the list will automatically be sent to all devices in the
list.
Now let's see how the code example shown above would translate into NetLinx. This is code that would
function correctly within a NetLinx system, but still uses the Axcess-based.
DEFINE_CONNECT_LEVEL
DEFINE_DEVICE
VIRTUAL1 = 33000
TP1 = 128
TP2 = 129
TP3 = 130
DEFINE_CONNECT_LEVEL
(VIRTUAL1, 1, TP1,1, TP2,1, TP3,1)
The example above combines the levels for the three touch panels:
change occurs on any of the three devices, NetLinx detects the level as coming only from
The example below illustrates the use of a device array (
