The following table indicates the QD60P8-G functions.
This function counts from 0 to 99999999 and detects an overflow
when the count range is exceeded.
This function repeats counting between 0 and 99999999.
This function turns ON the accumulating counter comparison flag
when the accumulating count value reaches or exceeds the
comparison output setting value. (The accumulating counter
comparison flag turns OFF at a comparison signal reset request.)
This function changes the count cycle of the sampling pulse
number or accumulating count value.
This function performs movement averaging processing by the
specified number of times if there are variations in the sampling
pulse number.
This function converts the input pulse number into the unit pulse
number when its weight per pulse is a fraction.
This function sets the upper/upper limit value, upper/lower limit
value, lower/upper limit value and lower/lower limit value for the
sampling pulse number converted by the pre-scale function to
output alarms.
This function resets the sampling pulse number, accumulating
count value or input pulse value. A reset can be made at any
timing.
This function selects whether the rise or fall of an input pulse will
be used for counting. (This setting can be made for each channel
using the intelligent function module switch.)
This function starts input pulse count operation when the count
enable signal is turned ON.
This function changes the module without stopping the system.
(Perform an online module change according to the messages of
GX Developer.)
This function uses the utility package (GX Configurator-CT) to
perform initial setting, auto refresh setting, monitor/test or similar
from within the software without using sequence programs.
POINT
The above functions can be used in combination.
However, the linear counter function and ring counter function cannot be used
together.
Please select either of them.
