Laser marking
The laser marker gives every board its identity. Everything recorded later on the line hangs on this one code, so the MES makes sure that no code is ever used twice.
Where the data comes from
- Marking head
- Writes the code; the program and the mark time come from here.
- The code on the board
- The code is scanned at every later station, and every record hangs on it.
- Operator screen
- Shows the work order and the last serial, so a restart never reuses a code.
What we record at LM-1
Example values from the demo board KRZ-0917-00042. The source says where each fact comes from: the machine itself, a scan, an operator or the MES.

| Code type and size | DataMatrix 18 by 18 | Machine |
| Panel and position | Panel P-0917-007, board 3 of 4 | MES |

Checks at this station
Rules the station applies before a board moves on. Which ones run on your line is agreed with production and quality.
- No duplicate serials
- A code that already exists in the record is refused before it is marked.
- Numbered your way
- Serials follow the identifier scheme set for each product, with its own counter, so the format stays the one your customer expects.
- The right program
- The marking program must match the product of the running work order.
In the manufacturing record
This is the line the station adds to the record of the board, the same record that follows it through the whole line.
