Q is triggered for Present Time (PT) after a positive flank.
Note that if a new positive flank is received while Q is
high, the “on” timer will be reset and the output will be
held high for a new PT time.
The CTU has one output Q.
PV is the preset value of the counter i.e. the counter value
to reach for the output to be forced high.
The counter up has a current counter value CV. When CV
is equal to PV the output Q goes high.
CV is incremented after every positive flank of the CU
input
Note that if CV = PV, then CV is not incremented.
CV is reset after a positive flank on the input R.
The output Q is kept high while CV = PV and until R
receives a positive flank
The CTD has one output Q.
PV is the preset value of the counter i.e. the start value of
the counter.
The counter down has a current counter value CV. When
CV is equal to zero the output Q goes high.
CV is decremented after every positive flank of the CD
input
Note that if CV = 0, CV is not decremented.
CV is reloaded (CV is set equal to PV) after a positive
flank on the input LD.
The output Q is kept high while CV = 0 and until LD
receives a positive flank.
