| Step | Check | Result | Code | Note |
|---|---|---|---|---|
| 10 | Was processing possible in the backend of the MSB? | no | A01 | Backend of the MSB is overloaded. |
| — | — | yes | → Step 20 | — |
| 20 | Was a communication connection to the control box possible? | no | A02 | The communication link to the control box is faulty. |
| — | — | yes | → Step 30 | — |
| 30 | Was it procedurally possible to implement the control command? | no | A03 | Process-wise it is currently not possible to implement the request (e.g. due to maintenance work). |
| — | — | yes | A04 | The control command can in principle be implemented. |
## Result codes
| Result code | Cluster | Meaning |
|---|---|---|
| `A01` | — | Backend of the MSB is overloaded. |
| `A02` | — | The communication link to the control box is faulty. |
| `A03` | — | Process-wise it is currently not possible to implement the request (e.g. due to maintenance work). |
| `A04` | — | The control command can in principle be implemented. |

**No** consistency check was carried out for this decision tree — no generated BPMN found. Whether the MACO APP implements this tree completely is therefore not evidenced here.
