| `xRequest`         | *FALSE*     | Trigger für einmaliges Lesen                  |
| `xRequestVisu`     | *FALSE*     | Trigger für einmaliges Lesen (Visualisierung) |
| `tRequestTime`     | *T#0S*      | Intervall für zyklisches Lesen                |
| `eDPT_Format`      | -           | DPT 19.x Format-Auswahl                       |
| `byAdrGroup`       | *0*         | Gruppenadresse (0-255)                        |
| `byAdrMiddleGroup` | *0*         | Mittlere Gruppenadresse (0-7)                 |
| `byAdrMainGroup`   | *0*         | Hauptgruppenadresse (0-31)                    |
| `dtInitValue`      | -           | Initialwert (nicht wirksam)                   |
| `eInitOption`      | -           | Initialisierungsoption                        |

#### Ausgänge

* `wYear` (WORD): Jahr
* `wMonth` (WORD): Monat
* `wDayOfMonth` (WORD): Tag des Monats
* `wDayOfWeek` (WORD): Wochentag
* `wHourOfDay` (WORD): Stunde
* `wMinutes` (WORD): Minuten
* `wSeconds` (WORD): Sekunden
* `tNextRequest` (TIME): Zeit bis zum nächsten Lesevorgang

#### Verwendung

1. Wählen Sie das DPT 19.x Format mit `eDPT_Format`.
2. Konfigurieren Sie die Leseoptionen:
   * Für zyklisches Lesen: `tRequestTime` > T#0S
   * Für ereignisbasiertes Lesen: Nutzen Sie `xRequest` oder `xRequestVisu`
3. Setzen Sie `eInitOption` für die Initialisierung (Beachten Sie, dass `dtInitValue` nicht wirksam ist).
4. Überwachen Sie die einzelnen Zeitkomponenten (wYear, wMonth, etc.) für empfangene Werte.
