Update of actual values (on every rising edge
)

| | Input | `wBaseAdressMbusDevice` | `WORD` | 10 | Modbus - base register for the information of the MBus device | | Input | `xResError` | `BOOL` | FALSE |

Reinitialization of the outputs eErrorCodeCom in the
fault-free state (on each rising edge)

| | Inout | `ModbusClient` | `ModbusClientBase` | | Client of the device | | Output | `dwMeterID` | `DWORD` | | Serial number of the MBus device | | Output | `sManufacturer` | `STRING` | | Manufacturer ID of the MBus device | | Output | `byMeterGeneration` | `BYTE` | | Version of the MBus device | | Output | `eMedium` | SOLVIMUS\_GE20\_MBUS\_DEVICE\_MEDIA\_TYPE | | Media ID of the MBus device | | Output | `dtSysTime` | `DT` | |

Timestamp of the MBus device (UTC, in Germany UTC +1 /
+2 h depending on summer / winter time)

| | Output | `wStatusFlags` | `WORD` | | Current status of the status flags | | Output | `xAlarm` | `BOOL` | FALSE | Collective fault (TRUE = fault) | | Output | `xAlarmCom` | `BOOL` | FALSE | Collective fault - communication (TRUE = fault) | | Output | `eErrorCodeCom` | ModbusErrorCode | | Error code - communication (0 = no error) | | Output | `xBusy` | `BOOL` | | Communication indicator (TRUE = communication) | | Input Const | `diAdrOffset` | `DINT` | 0 |

Offset for calculating the Modbus addresses (from the Modbus
registers) (permitted range: -1, 0, +1)

GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com. ## Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question. Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter: ``` GET https://support.powerio.com/hub/codesys-hvac/en/hvac-modbus-library/functionblocks/solvimus/solvimus_ge20_mbus_device.md?ask=&goal= ``` `ask` is the immediate question: it should be specific, self-contained, and written in natural language. `goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
