j.
The second rung does the followings:
if
( count >=
10 )
{
count = 0;
//set the count to zero
}
Step 9: Save and Close (the Ladder).
Step 10: Tune the scan time if necessary.
a.
Click the menu [HMI] > [Refresh Time (I/O Scan)] to set the scan time.
b.
The default scan time is 100 ms. The scan time is the time interval between two
consecutive Ladder scan. That is, TouchPAD executes each rung of the ladder serially
from the first rung to the last and after finishing the last rung, it waits until the scan
time interval is up (the scan time interval is calculated from the time of the first rung’s
execution) to execute from the beginning (the first rung) again.
c.
The scan time might influence the feeling of sensitivity. If the scan time is too small,
touching the BitButton on the screen one time may causes it triggering many times
and thus makes the counter increment more than one.
