Siemens WAITM/WAITMC/SETM/CLEARM: Siemens multi-channel synchronization

Coordination commands between channels: WAITM wait with exact stop, WAITMC without exact stop, SETM activates mark, CLEARM deletes it.

For reference only: syntax changes with the control, the post-processor and the machine parameters. Check the official manual and run a simulation before cutting. Legal notice.

Family: Siemens
Machine: Milling, Turning, Mill-turn
Risk: High
Example: WAITM(5, 1, 2) ; esperar marca 5 en canales 1 y 2
