3.1 Flexible NC programming
Note
GETVARPHU can be used, for example, to check whether both variables have the expected
physical units in a variable assignment a = b.
Read access right
Syntax:
<Result>=GETVARAP(<name>,<access>)
Meaning:
<result>:
GETVARAP:
<name>:
<access>:
Example:
Program code
DEF INT result=0
result=GETVARAP("$TC_MAP8","WB")
IF (result < 0) GOTOF error
The value 7 is returned as result. This corresponds to the key switch position 0 (= no access
protection).
