7.5.5 I/O Point Marking
Point marking process has only start delays, so the end sequence in the example above is put to Start Delay 4 and Start Delay5.
The example above is a typical point marking I/O map when the plasma is used for point marking. This is the same as line
marking but without machine movement.
SD4
SD5
- Drill head stays down
- Drill turns ON
- Timer counts down for 1s before
sequence moves to SD5.
- Drill head turns OFF and starts
to move up
- Drill turns OFF
- Timer counts down for 20s and
waits for inbit 9 to turn ON before
sequence moves to SD4.
Outbits 17 and 18 ON
Machine moves to drill point
Machine moves to next pierce point
SD3
Outbit 17 ON
- Drill head commanded down
- Timer counts down for 20s and
waits for inbit 8 to turn ON before
sequence moves to SD4.

The example above is a typical point marking I/O map when a drill is used. Here outbit 17 commands the drill head to go
down, 18 turns the drill on and inbits 8 and 9 are used to check whether the drill has reach down position or upper position.
If neither inbits are received in the 20s time period an error message will be prompted “No inbit 8 Drill Head Down” or “No
inbit 9 Drill Head Up” and the drilling sequence will be canceled.
NOTE!
Only hardwire marking supported.
