3.4.2 Using OUT to drive an STL coil
This has the same operational features as usin
SET. However, there is one ma
or function
which SET is not used. This is to make what is termed ‘distant
umps’.
OUT is used for loops and jumps
If a user wishes to ‘
ump’ back up a pro
ram,
i.e.
o back to a state which has alread
been
processed, the OUT instruction would be used
with the appropriate STL state number.
Alternativel
the user ma
wish to make a
lar
e ‘
ump’ forwards skippin
a whole section
of STL pro
rammed states.
Out is used for distant jumps
If a step in one STL pro
ram flow was required
to tri
er a step in a second, separate STL
pro
ram flow the OUT instruction would be
used.

Note:
Althou
h it is possible to use SET for
umps and loops use of OUT is needed for
displa
