Tap, don't type.
Every machine gets a panel (a touch screen, also called an HMI, human-machine interface). It is built for operators who are busy, wear gloves, or may not read well.
- Big Start and Stop buttons in clear colours
- Stop reasons as pictures: breakdown, no material, changeover, break, cleaning
- Nobody types a code or an ID, ever
- The panel remembers its machine, and checks the machine still exists
