if digital input 1 is low, load 60 msec
on counter
if digital input 1 is high for 60 msec
b99.0 will be set to 1 and b90.11=1
if digital input 1 is high, load 60
msec on counter
if digital input 1 is low for 60 msec,
b99.0=1 and b90.11=0
b90.11 is the status of filtered digital
input 1
calculate difference between Pr0 and
Pr80 to set b99.2 and b99.3
