Note: Other machine functions, like tool change (usually M06) or coolant control, have their M-code value specified by the PLC application not by the CNC software. Most of the M-code values in above list are configurable.

Other M-codes (up to M699) can be handled by the PLC application based on the particular machine requirements.
