5.7.5 TTMR (FNC 64)
Operation:
The duration of time that the TTMR instruction is
ener
g
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
y
the
factor selected b
y
the operand n, is moved in to
re
g
ister D. The contents of D could be used as the
source data for an indirect timer settin
g
or even as
raw data for manipulation.
When the TTMR instruction is de-ener
g
ized D
+1
is
automaticall
y
reset (D is unchan
g
ed).
