5.7.5 TTMR (FNC 64)
Operation:
The duration of time that the TTMR instruction is
ener
ized, is measured and stored in device D
+1
(as a count of 100ms periods).
The data value of D
+1
(in secs), multiplied b
the
factor selected b
the operand n, is moved in to
re
ister D. The contents of D could be used as the
source data for an indirect timer settin
or even as
raw data for manipulation.
When the TTMR instruction is de-ener
ized D
+1
is
automaticall
reset (D is unchan
ed).
5.7.6 STMR (FNC 65)
Operation:
The desi
nated timer Swill operate for the duration
n with the operational effect bein
fla
ed b
devices D+0to D+3. Device D+0is an off-dela
timer, D+1is a one shot timer. When D+3is used in
the confi
uration below, D+1and D+2act in a
alternate flashin
sequence.
