Sequence instructions
As
with the programmable controller, there are the following sequence instructions, all
of
which are
of the instantaneous progressing type
(1
msec or less).
Contact instructions such as LD/LDI, AND/ANI, and
OR/ORI
are used
to
drive coil instructions such
as
SET/RST
and CJ/CJN (see page
126).

an
addition and subtraction operation instruction as well as a parallel contact connection instruction
Example
1
ADR +1,000
ADR +2,000 Set value register
SVR
stores
+1
,000
+2,000
=
+3,000.
OR

Example
2
EXT K654
When the digital switch DSW#654
=
100,
set value register
SVR
stores 100 -400
=
-300.
OR
I
ADR
-400 (EXT K designated by a
DSW
is regarded as a positive number.)
Example

EXT K70
EXT K654
OR
OR
t
When BFM#ll and
#10
=
+500,
DSW#654
=
100, and BFM#13 and #12
=
1000,
+500
+lo0
=
+600 and +600
-1000
=
-400.
Set value register stores -400.

The above examples show an addition
of
set values designated
by
2 ADR or EXT instructions.
The following additions use
OR
instructions.
