Measurement (M5)
13.5 Tool measuring in JOG
Turning, Milling, Nibbling

● The axis is repositioned by the NC program, the probe is approached again, and finally
retracted. The HMI then transmits the command to switch back to JOG mode (V1800
0000.2) to the PLC. The "Change mode disable" interface signal (V3000 0000.4) is then
reset by the PLC. The PLC outputs JOG mode (V3000 0000.2) to the NCK and the NCK
returns the IS "JOG mode active" (V3100 0000.2) to the NCK.
● The next direction of approach/axis for traversing to the probe is selected with the "Next
step" softkey. The further procedure is analogous - until all directions/axes have been
traversed.
After measuring or probe calibration is complete the function can be deselected via the
"Back" softkey. This also resets the IS "Measuring in JOG active" (V1700 0003.0). It is also
reset when the operating area is exited. The automatic program can be cancelled via IS
"Reset" (V3000 0000.7) or measuring in JOG can be closed via the the "Back" softkey. This
also cancels any set IS "Feed disable" (V3200 0006.0) and IS "Change mode disable"
(V3000 0000.4) or intermediately saved signals.
PLC user program
The required functionality corresponding with the above-described procedure in the PLC
user program must be provided by the user.
The toolbox for SINUMERIK 802D sl supplied by SIEMENS includes a user example in the
PLC library. You can use this. In this case it should be noted that PLC_INI (SBR32) and
MCP_NCK (SBR38) must always be opened in OB1 as these transfer the signals of the
MEAS_JOG (SBR43) subroutine to the NCK/HMI.
