PulseCount (Dest, Reps, PChan, PConfig, POption, Mult, Offset)
Makes a measurement on a pulse channel.
With the PulseCount instruction, a pulse channel can be configured as a high
frequency input, a low level AC input, or as a switch closure input. Control
ports can be configured as high frequency input or switch closure.
PulseCountReset is used to reset both the pulse counter and the running
average values in the pulse count instruction. The 24-bit counter can count up
to 16,777,215. Each scan of the datalogger causes the counter to output the
number of pulses accumulated since the last scan. If the scans stop, as in a
program with more than one scan loop, the counter continues to accumulate
counts until an overrange occurs or a scan is initiated.
