Reading configuration data—PARA
The PARA function is used to read configuration data. To do this, use
the parameter designations from the configuration parameters. You
also use the designations from the configuration parameters to read
user parameters.
When you read optional parameters, check whether the return value
is valid. Depending on the data type of the parameter (REAL/STRING),
the value "0" or the text "_EMPTY" is returned when reading an optional
attribute that has not been set.
Example: PARA function
Access to configuration data
Syntax: PARA(key, entity, attribute, index)
 Key: Key word
 Entity: Name of the configuration
group
 Attribute: Element name
 Index: Array number if the attribute is
from an array
. . .
N.. #l10=PARA("","CfgDisplayLanguage","ncLanguage") Reads the number of the currently selected
language
N.. #l1=PARA("","CfgGlobalTechPara","safetyDistWorkpOut") Reads the external safety clearance on the
machined part (SAT)
N.. #l1=PARA("Z1","CfgAxisProperties","threadSafetyDist") Reads the thread safety clearance for Z1
N.. #l1=PARA("","CfgCoordSystem","coordSystem") Reads the machine orientation number
. . .
#x2=PARA("#x30","CfgCAxisProperties","relatedWpSpindle",0) Check whether the optional parameter is set
IF #x2<>"_EMPTY" Evaluation:
THEN
[ The parameter "relatedWpSpindle" was set ]
ELSE
[ The parameter "relatedWpSpindle" was not set ]
