Combining Devices, Levels, and Channels

NetLinx Programming Language Reference Guide
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. The syntax must follow one of these two forms:
DEFINE_CONNECT_LEVEL
(Vdevice1, 1, DEVLEV [ ])
- or -
DEFINE_CONNECT_LEVEL
(VDEVLEV, DEVLEV [ ])
Combining levels
COMBINE_LEVELS connects a single device-level array (DEVLEV[ ]) to a DEVLEV array.
Any element in a
DEVLEV array appears to come from the virtual device-level representing the group,
and output to any element in a
DEVLEV array is directed to all elements in the group. Here's a syntax
example:
COMBINE_LEVELS (DEVLEV VDLSET, DEVLEV[ ] DLSETS)
Parameters:
Un-combining levels
UNCOMBINE_LEVELS undoes the effect of COMBINE_LEVELS. All combines related to the specified
virtual device-level are disabled.
UNCOMBINE_LEVELS (DEVLEV)
Parameters:
COMBINE_LEVELS(VDL, DLSet)
.
.
UNCOMBINE_LEVELS(VDL)
The NetLinx code example below illustrates how to dynamically combine and un-combine levels.
DEFINE_DEVICE
VIRTUAL1 = 33000
TP1 = 128
TP2 = 129
TP3 = 130
VDLSET Virtual device-level. Each element will represent one device-level combine group.
DLSETS Device-level sets containing the device-level pairs to combine. Corresponding ele-
ments in each set are combined with the corresponding element in the virtual device-
level array.
VDL The virtual device-level passed to COMBINE_LEVELS.
DEVLEV The device-level passed to COMBINE_LEVELS.
Input and output changes occurring on non-combined panels will not affect combined
panels, and vice versa.
