Additional diagnostic data
The following additional diagnostic data supports startup and facilitates troubleshooting during operation:
- Feedback contacts of the switching elements – The feedback contacts of the switching elements of the energy storage synchronization and the multi-stage safety concept are provided as a bit field on PI X+1.
- Fault response of current fault – each fault has a stored fault response. This fault response of the current fault is provided on PI X+2. For further information, refer to chapter Fault Manager (FaultManager).
- Remaining runtime error response – Remaining runtime of the current error response (if the output stage is inhibited with a delay or the storage unit is disconnected with a delay) is provided on PI X+3. If the time has expired or there is no delay, 0 is returned.
- Selected fault – The fault that was selected in the fault list under the selected list index is provided via PI X+4. The selection is also made on PI X+4 for the setpoints.
- Maximum storage temperature – The highest storage temperature known to storage monitoring is provided via PI X+5. This temperature is also provided via the user interface.
- Current consumer power – The sum of all consumer powers known to power monitoring is supplied via PI X+6.

PI X+2 | Fault response of the current fault |
| 10, 20, 30, 40 See Fault responses |
PI X+3 | Remaining runtime error response |
| Remaining runtime until the output stage is inhibited and/or the storage unit is disconnected |
PI X+4 | Selected fault |
| Fault in the fault chain of the pending faults whose index is selected for the setpoints. If 0, the first fault that occurred is displayed. |
PI X+5 | Maximum storage temperature |
| Maximum of all measured individual module temperatures of the additional function "Storage monitoring" in [±10-1 °C] |
PI X+6 | Sum of all consumer powers |
| Sum of all power ratings of the consumers (MDS, MDA, ...) in [±10-1W] |

PO X+2 | Set test fault |
| Setting a fault response 10, 20, 30 or 40. This can trigger a corresponding fault. This fault has its own test fault code. |

PO X+4 | Fault selection |
| Fault in the fault chain of the pending fault whose index is selected for the setpoints. If 0, the first fault that occurred in time is displayed. |
