2.11.5 VARIABLES (Cent’d)

Item
Concept of “#O”
Variable
is commanded in
the replacement
(1) Variable
is commanded in
the part program
(2) On F commands
Variable
is commanded in
the condition of
and
Others
Blanks in
conditions
except EQ and
NE are
treated
as O.
Meaning of (Blank)
. #O defined as variables
of blank>
. Commanding #O at the
left-hand side of the
causes
. Where #2 is blank>
command #3=#2; means
#3= .
. Where #2 is command
GOO X #2: equivalent to COO
is ignored.)
F figure 1, F 2:
Numeral 1 and numeral 2 include
Indirect
#2
Blank Full - Blank
Blank Blank - Numeral 2
Full
Blank - Numeral 1
Full Full - Numeral 2.. . Note
. Where #2 is #3 is O
Condition “IF #3 #2”
is not established.
Condition “IF #3 EQ
#2 is established,
#3=#[ . . is blank.
#3=#2 * #O:
#3=#o + I
#3=#o/#o;
#3=5*#o ;
mands, #3=0,
#3=2-#O; means #3=2
#0: causes alarm.
Blank” in the replacement
other than described above
is treated as “O. ”
. Condition is
established when #2 and #3
are , or #2 is O
and #3 is .
. Condition IF #3LT #2 is
not established when #2 and
#3 are , or #2 is
and #3=0.
Note: Parameter setting can be made to select whether to
cause double address error to enable numeral 2, when both
numeral 1 and numeral 2 are full.
Setting parameter #6073 D3 1: Numeral 2 is effective
o: Double address error
2.11.6 OPERATION COMMANDS
Various operations can be performed between
variables and between variables and constants .
The operation expression is represented in the
form of #i
❑
, in which
is a general arithmetic operational expression pro-
duced by combining variables and constants with
and functions. The available
and functions are as follows. Instead of
and #k, constants may be used.
Note: must be commanded at the
right-hand side of the equation,
(1) Variable Definition and Replacement
Definition, replacement.
Indirect specification
(2) A d d - T y p e O p e r a t i o n s
. . .
#i = - #k . . Difference.
Logical sum (for each of
32 bits) .
Exclusive logical sum
(for each of 32 bits) .
(3) M u l t i p l y - T y p e O p e r a t i o n s
#i = *#k . . . Product.
#i
❑
#k . . . Quotient.
#i
❑
AND #k . . . Logical product
(for each of 32 bits) .
Note: In OR, XOR, or AND operation, the
variable value (or constant) is converted into
the binarv 32-bit equivalent and the operation
is performed on
(4)
#i

,SIN [#j]
bit.
. . . Sine (in degrees) .
. . . (in degrees) .
. . . Tangent (in degrees) .
#i
❑
A T A N [ # j ] / [ # k ]
[#j]
. .
BIN [#j]
. . .
#i
❑
ROUND . . .
FIX [#j]
Arctangent
Square root.
Absolute value.
Convert from BCD .
Convert into BCD.
Produce integer by rounding
Truncate the fractions.
Raise the fractions to a unit.
(5) Combinations of operations
The above operations and functions may be used
in combinations.
A functional operation is per-
formed first. Then, a multiply-type operation is
p e r f o r m e d . An add-type operation is performed
last.
Sample #i = + #k * SIN
(6) C h a n g e o f o p e r a t i o n a l o r d e r b y [ 1
Priority can be given to an operation by enclosing it in
brackets [ ]. Up to quintuple (five-hold) nesting of
brackets is permitted including those of functional
operations.
