SAMPLE (Sample a statement)
Unitary pre-APOGEE APOGEE BACnet
   
Syntax
SAMPLE(sec) line
sec Interval in seconds between evaluations of state.
• This value must be entered as an integer ranging
from 1 to 32,767.
line Any PPCL statement that does not include its own timing
function. This includes: WAIT, PDL, TOD, TIMAVG, LOOP,
SSTO, or another SAMPLE command.
Use
Defines how often a command is evaluated. The SAMPLE command
can be helpful in situations, such as preventing short cycling in
ON/OFF decisions or reducing COVs from noisy flow transmitters.
Example
200 SAMPLE(600) ON(HALFAN)
Notes
The SAMPLE command executes immediately on a return from
power failure, after an ENABLE command, or during the first
execution of PPCL following a database load.
Valid commands can include assignment, calculations, and program
control (GOTO, GOSUB).
