Read In Word Range - HEIDENHAIN TNC 415 Technical Manual

4.1.2 Read in Word Range (Module 9010/9011/9012)
A byte, word or doubleword is read from the defined position in the word memory and returned to
the stack as an output variable. Indexed reading in the memory is possible by specifying a variable
as the name of the memory cell.
Possible errors:
- The defined address is outside the valid range (0..1023).
- Module 9011: The defined address is not a word address (not divisible by 2).
- Module 9012: The defined address is not a doubleword address (not divisible by 4).
Call:
PS B/W/D/K <Number of byte to be read>
