Table 4-3. Operator Usage - Description And Examples
OPERATOR DESCRIPTION USAGE EXAMPLE
< less than Evaluates two expressions and is
true if the one on the left is less
than the one on the right.
tcon01.PV < 100
<= less than or
equal to
Evaluates two expressions and is
true if the one on the left is less
than or equal to the one on the
right.
tcon01.PV <= 100.7
> greater than Evaluates two expressions and is
true if the one on the left is greater
than the one on the right.
tcon01.PV > tcon01.SP
>= greater than or
equal to
Evaluates two expressions and is
true if the one on the left is greater
than or equal to the one on the
right.
tcon01.PV >= 0.25
== equal Evaluates two expressions and is
true if the one on the left is equal
to the one on the right.
ani01.AIH == 0
!=
not equal Evaluates two expressions
and is true if they are not
equal.
ani01.PA != 0
+ add The addition operator causes
the two values on either side
of it to be added together
yielding the sum of the two
values.
tcon01.PV + tcon01.SP > 500
- subtract The number after the - sign is
subtracted from the number
before the sign.
ani01.OUT - tcon01.SP == 0
* multiply The multiplication operator
multiplies the values on either
side of it, yielding the product
of the two values.
tcon01.PV * 0.5 < 4658.0
/ divide The value to the left of the / is
divided by the value to the
right.
(tcon01.PV + 500) / 2 >
ani01.OUT
- minus The minus sign is used to indi-
cate or change the algebraic
sign of a value. This is a unary
operator which takes just one
operand.
ani10.OUT > -50
! logical "not" Evaluates the expression on
the right and is true if that
expression is false, and vice
versa.
!ani01.PA
