Transmission
This variable is transmitted immediately when the
corresponding network input variable has changed more
than 1 % or immediately as an answer to an
nviAoValuePct[ ] or nviAoSwitch[ ] update.
Default Service Type
The default service type is unacknowledged.
Analog Output Command – nviAoSwitch[ ]
This network variable is used to drive the analog output to
0 … 100 %.
It is typically bound to a L
ONWORKS control device issuing an
output level 0 … 100 %.
If both nviAoSwitch[ ] and nviAoValuePct[ ] receive valid
values, nviAoValuePct[ ] will have priority.
Default Value
