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)

N.. #L1=PARA("Z1","CFGAXISPROPERTIES","THREADSAFETYDIST")
Reads the thread safety clearance for Z1
N.. #L1=PARA("","CFGCOORDSYSTEM","COORDSYSTEM")

. . .
#X2=PARA("#X30","CFGCAXISPROPERTIES","RELATEDWPSPINDLE",0)
Check whether the optional parameter is set
