TNC 407/TNC 415/TNC 425 2 Program creation 7-21
The number transfer from the PLC to the machining program is carried out by the Q parameters
Q100 to Q107, i.e. the Q Parameters Q100 to Q107 can be overwritten by the PLC. The required
numerical value is entered in doubleword D528 and the Q parameter number (0-7) is defined in
Word W516. The transfer is activated by the strobe marker M2713. The Q parameter values are
transferred with the next M/S/T strobe.

Address Function
D 528 Doubleword with multiple function, in this instance data for transfer
from the PLC to the NC (0–7, Q number from W516, strobe marker
M2713)
W516 Q number for numerical value transfer from PLC to NC (transfer of
the value from D528, strobe marker M2713)
122 different machine parameters are reserved for data transfer in the PLC. MP4210.x, MP4220.x
and MP4310.x are stored in PLC words. The contents of MP4230.x and 4231.x must be called by
module 9032. 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.
Although the TNC 407 / TNC 415F / TNC 425E accept entry values to 0.0001 mm (or °), the controls
round these values to 0.001 mm (or °) for their calculations.
