Variable Minimum, Maximum And Range (Minval, Maxval And Bound) - Siemens Sinumerik 840D sl Programming Manual

1.6 Variable minimum, maximum and range (MINVAL, MAXVAL and
BOUND)
Function
The MINVAL and MAXVAL commands can be used to compare the values of two variables.
The smaller value (in the case of MINVAL) or the larger value (in the case of MAXVAL)
respectively is delivered as a result.
The BOUND command can be used to test whether the value of a test variable falls within a
defined range of values.
Syntax
<smaller value>=MINVAL(<variable1>,<variable2>)
<larger value>=MAXVAL(<variable1>,<variable2>)
<return value>=<BOUND>(<minimum>,<maximum>,<test variable>)
Significance
MINVAL:
<smaller value>:
MAXVAL:
<larger value>:
BOUND:
<minimum>:
<maximum>:
<return value>:

1.6 Variable minimum, maximum and range (MINVAL, MAXVAL and BOUND)

Obtains the smaller value of two variables (<variable1>,
<variable2>)
Result variable for the MINVAL command
Set to the smaller variable value.
Obtains the larger value of two variables (<variable1>,
<variable2>)
Result variable for the MAXVAL command
Set to the larger variable value.
Tests whether a variable (<test variable) is within a defined
range of values.
Variable which defines the minimum value of the range of values.
Variable which defines the maximum value of the range of values.
Result variable for the BOUND command
If the value of the test variable is within the defined range of
values, the result variable is set to the value of the test variable.
If the value of the test variable is greater than the maximum value,
the result variable is set to the maximum value of the definition
range.
If the value of the test variable is less than the minimum value, the
result variable is set to the minimum value of the definition range.
