Determining the index of a parameter element—
PARA
You activate the index search for an element by appending the name
of the list element to the attribute, separated by a comma.
Example:
Determining the logical axis number of spindle S1
#c1 = PARA( "", "CfgAxes", "axisList,S1", 0)
The function returns the index of the "S1" element in the "axisList"
attribute of the "CfgAxes" entity. The index of element S1 equals the
logical axis number in this example.
Access to configuration data
Syntax: PARA("key","entity","attribute,elem
ent", index)
 Key: Key word
 Entity: Name of the configuration
group
 Attribute,name: Attribute name and
element name
 Index: 0 (not required)
Without the attribute extension "S1", the function would
read the element located at the list index number 0. Since
the element is a string in this example, the result has to be
assigned to a string variable.
#x1 = PARA( "", "CfgAxes", "axisList", 0)
The function reads the string name of the element at list
index number 0.
