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 Doubleword
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.
The Q parameter values are transferred with the next M/S/T strobe.

Sixty different machine parameters are reserved for data transfer in the PLC. These machine
parameters are kept in the Doublewords D768 to D956 and the Words W960 to W968 and W976 to
W988. For example, PLC positioning, datum shifts, feed rates for PLC positioning or coding for the
release of certain PLC functions can be filed in these machine parameters. These numerical values
are evaluated in the PLC program.
