z Use the AND and ANI instructions for serial connection of contacts.
As many contacts as required can be connected in series. They can
be used for many times.
z The output processing to a coil, through writing the initial OUT
instruction is called a “follow-on” output (For an example see the
program below: OUT M2 and OUT Y003). Follow-on outputs are
e output order is correct. There’s
contacts’ No. and follow-on outputs’
permitted repeatedly as long as th
no limit for the serial connected
number.
