2.5 Out
Basic points to remember:
- Connect the OUT instruction directl
to the ri
ht hand bus bar.
- It is not possible to use the OUT instruction to drive ‘X’ t
pe input devices.
- It is possible to connect multiple OUT instructions in parallel (for example see the
previous pa
e; M100/T0 confi
uration)
2.5.1 Timer and Counter Variations
When confi
urin
the OUT instruction for use as either a timer (T) or counter (C) a constant
must also be entered. The constant is identified b
the letter “K” (for example see previous
pa
e; T0 K19).
In the case of a timer, the constant “K” holds the duration data for the timer to operate, i.e. if a
100 msec timer has a constant of “K100” it will be (1005 100 msec) 10 seconds before the
timer coil activates.
With counters, the constant identifies how man
times the counter must be pulsed or tri
ered
before the counter coil activates. For example, a counter with a constant of “8” must be
tri
ered 8 times before the counter coil finall
ener
izes.
