4.11 Inserting an NC block (Module 9150)
With Module 9150 is it possible to define an NC block during an active M/S/T/G/Q output from the
NC to the PLC, or also when no program has been started. The defined NC block is executed after
the acknowledgement of the M/S/T/G/Q strobe (immediately, if no PGM is started), before the
control continues with the execution the NC program.
Constraints:
- If there are several commands during a strobe output, only the last one is executed.
- If there are several commands when the spindle is stationary, it is not defined which command is
recognized.
- Erroneous parameters (e.g. incorrect tool number, non-existent file) result in a abortion of the NC
program with the corresponding error message. If the error occurs while the spindle is stationary,
there is no error message.
Possible errors:
- The call was made during a running NC program without active M/S/T/G/Q strobe.
- The call was made with an unknown command code.
Call:
PS B/W/D/K <Command code>
0: TOOL-CALL
