2.5 Out
Basic points to remember:
- Connect the OUT instruction directl
y
to the ri
g
ht hand bus bar.
- It is not possible to use the OUT instruction to drive ‘X’ t
y
pe input devices.
- It is possible to connect multiple OUT instructions in parallel (for example see the
previous pa

2.5.1 Timer and Counter Variations
When confi

urin
g
the OUT instruction for use as either a timer (T) or counter (C) a constant
must also be entered. The constant is identified b
y
the letter “K” (for example see previous
pa
g
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
y
times the counter must be pulsed or tri
gg
ered
before the counter coil activates. For example, a counter with a constant of “8” must be
tri
gg
ered 8 times before the counter coil finall
