1.5.3 Expressions
An expression is any valid combination of operators, constants,
parameters and variables.
The priorities of the operators and the way they can be associated
determine how these expressions are calculated:
Brackets should be used in order to clarify the order in which the
expression is to be evaluated. Using redundant or additional brackets
will neither cause errors nor slow down the execution.
P3 = P4/P5 - P6 * P7 - P8/P9
P3 = [P4/P5] - [P6 * P7] - [P8/P9]
Arithmetic
Their result is a numerical value. They consist of a combination of
arithmetic and binary operators with constants, parameters and
variables.
This type of expressions may also be used to assign values to
parameters and variables:
P100 = P9 P101 = P[P7] P102 = P[P8 + SIN[P8*20]]
P103 = V.G.TOOL
V.G.FIXT[1].X=20 V.G.FIXT[1].Y=40 V.G.FIXT[1].Z=35
Relational
Their result is a TRUE or a FALSE. They combine relational and logic
operators with arithmetic expressions, constants, parameters and
variables.
... [P8==12.6] ...
It compares if the value of P8 is equal to 12.6.
... ABS[SIN[P4]] > 0.8 ...
It compares if the absolute value of the sine of P4 is greater than
0.8.
... [[P8<=12] + [ABS[SIN[P4]] >=0.8] * [V.G.TOOL==1]] ...
