HEIDENHAIN iTNC 530 HSCI - Data Transfer PLC - NC Program (Q-Parameters)

1714 HEIDENHAIN Technical Manual iTNC 530 HSCI
9.5.2 Data transfer PLC > NC program (Q-parameters)
Data transfer from the PLC to the NC program goes through Q parameters
Q100 to Q107, i.e., from the PLC you can overwrite Q parameters Q100 to
Q107:
 In double word D528, enter the numerical value to be transferred.
 In word W516, define the target parameter (0=Q100, 7=Q107).
 Activate transfer with strobe marker M4131.
 The iTNC transfers the values with the next strobe.
Q parameters in OEM cycles are only effective locally if the NC program of the
OEM cycle is saved in the *.CYC format, otherwise (*.H) the Q parameters are
effective globally.
Cycle 12 (PGM CALL) acts like CALL PGM, meaning the Q parameters are
effective globally.

Q parameters Effectiveness/Meaning
Q0 to Q99 Freely applicable parameters, as long as no
overlapping with SL cycles can occur, globally
effective for all programs stored in the TNC memory
Q100 to Q199 Parameters for special TNC functions
Q200 to Q1199 Parameters that are primarily used for cycles, globally
effective for all programs stored in the TNC memory
Q1199 to Q1399 Parameters that should primarily be used for OEM
cycles, and are globally effective for all programs
stored in the TNC memory. This may require
coordination with third-party suppliers.
Q1400 to Q1499 Reserved for OEM cycles (CALL-active)
Parameters that are primarily used for call-active OEM
cycles, and are globally effective for all programs that
are stored in the TNC memory.
