3.6.2 PLC/NC variable, write/read MD
The RNP (Read NC PLC)/WNP (Write NC PLC) commands can be used to read
and write NC or PLC variables.
Each time a WNP or RNP function is processed, NC/PLC variables are re-
accessed. This means that an NC/PLC access is always executed in a CHANGE
method. It is advisable to use this option in cases where a system or user variable
changes value frequently. If an NC/PLC variable is to be accessed only once, then
it must be configured in a LOAD or UNLOAD method.
Read
RNP ("System or user variable")
where:
System or user variable Name of NC or PLC variable
VAR2=RNP("$AA_IN[2]") ;Read NC variable
Write
WNP ("System or user variable", value)
where:
System or
user variable Name of NC or PLC variable
Value Value that is to be written to the system or
user variable.
