The Q parameters Q100 to Q107 transfer numbers from the PLC to the part program. This means
that Q100 to Q107 can be overwritten by the PLC. The numerical value is registered in Double word
D528 and the Q parameter numbers 0 to 7 are defined in Word W516. The numbers 0 to 7
correspond to parameters Q100 to Q107. The transfer is activated with the strobe marker M2713,
which must be set with the next M/S/T strobe.
Marker Function Set Reset
M2713 Activate the transfer of the value from D528
to the Q-Parameter defined in W516 PLC NC

Double word with multiple function, here data for transfer from the
PLC to the NC
W516 Q-Parameter No. for numerical transfer from PLC to NC
(0 – 7 = Q100 – Q107)

Various machine parameters are reserved for data transfer in the PLC. These machine parameters
are kept in the Double words D768 to D956 and the Words W960 to W974 and W976 to W1006.
PLC-positioning, datum-shifts, feed rates for PLC-positioning or coding for the release of certain
PLC-functions etc. can be filed in these machine parameters. The eroding parameters are still
available, which, depending on whether they are defined as Q parameters in the NC program or with
a table, are transferred by the NC or E-table into the PLC. The evaluation of all numerical values
transferred to the PLC takes place in the PLC program. (See chapter "Machine integration", section
"Eroding parameters.")
