The axis is repositioned by the NC program, the probe is approached again, and finally
retracted. The HMI then tr
ansmits the command to switch back to "JOG" mode
(DB1800.DBX0000.2) to the PLC. The "Change mode disable" interface signal
(DB3000.DBX0000.4) is then reset by the PLC. The PLC outputs "JOG" mode
(DB3000.DBX0000.2) to the NCK and the NCK returns the IS "JOG
mode active"
(DB3100.DBX0000.2) to the NCK.
After measuring or probe calibration is complete the function can be deselected via the following softkey:
This also resets the IS "Measuring in JOG active" (DB1700.DBX0003.0). It is also reset when the operating area is exited.
The automatic program can be cancelled via IS "Reset" (DB3000.DBX0000.7) or measuring in JOG can be closed via the
following softkey:
This also cancels any set IS "Feed disable" (DB3200.DBX0006.0) and IS "Change mode disable" (DB3000.DBX0000.4) or
intermediately saved signals.
The required functionality corresponding with the above-described procedure in the PLC user program must be provided by
the user.
The toolbox for the SINUMERIK 808D/SINUMERIK 808D ADVANCED 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.
