Control unit – Insert stop marks (insert command)
| Insert stop marks | |
| Description | During runtime, the PLC can use this control unit to set stop points in the future NC program. The control unit must then be enabled by enable_w = TRUE. The PLC signals a new assignment of command_2 by setting command_semaphor_rw to TRUE. The CNC sets the command_semaphor_rw to FALSE after the command_w data is read. |
