CNT (Pulse Counter)
The Messenger 570 system allows pulse counting on all eight analog inputs. It uses two commands in data mode,
CNT R, to display all eight counters, and CNT O, to clear individual counters.
The maximum transition rate is 100 state transitions/second (50 Hz signal = 50 counts/second) with no two
transitions occurring within less than 10ms of each other. The signal can be a square, saw-tooth, or sine wave, with
a transition being a change from above three volts and below two volts, and vice versa. Total counts are displayed
as decimals.
Help with the CNT command
Type CNT at the command prompt and the Messenger 570 system will return a list of valid counter commands
and related instructions.
