New Features
4 Changes
| Title | Description |
|---|---|
| Free-text filter for scan results | Data points from scan results can be filtered using freely definable text. This makes it possible to find relevant data points more quickly and incorporate them specifically into the project planning. |
| Mapping Based on an M-Bus Data Point Scan | Data points imported from an M-Bus scan can be mapped directly to new data points, eliminating the need for additional intermediate steps. |
| Device Configuration During M-Bus Scans | When importing data points from an M-Bus scan, the corresponding device entries are created automatically. Manual reconfiguration is not required. |
| Manufacturer Information in the Web Interface | The web interface displays information about the device manufacturer. This makes it easier to identify the appropriate contact person for support inquiries. |
Improvements
7 changes
| Title | Description |
|---|---|
| Notification After Uploading a Configuration | After uploading a configuration file, the data points and links it contains are immediately displayed in the web interface. This allows you to view the current configuration status without any additional steps. |
| Advanced SSH Authentication | The maximum number of public SSH keys that can be stored has been increased from 10 to 256. This allows more users to be authorized for secure remote administration of devices. |
| Serial Number in the Web Interface | A device's serial number is displayed on the dashboard under "Device" and in the system information. If no serial number is available, the message "unknown" appears. |
| Storing the BACnet Present Value | A bug has been fixed that prevented the configuration of BACnet property persistence bac_present_value in expert mode. Persistent storage of the value can be enabled via the web interface. |
| Optimized License Requests | License request packages contain additional device information that uniquely identifies the device. In addition, the packages can be retrieved via a new HTTPS interface, which is also used for downloads through the web interface. |
| Dispatch Error Message | If no mappable driver is active, a corresponding error message will be displayed in the web interface when the Dispatch button is pressed. |
| Logging Firmware Updates | Messages related to the installation process are displayed in the system log. This makes it easier to track and analyze errors that occur during firmware updates. |
Troubleshooting
6 changes
| Title | Description |
|---|---|
| Driver Configuration After Firmware Updates | A bug has been fixed that caused firmware updates to re-run the existing device customization process, which in turn could alter driver configurations. Existing driver configurations remain unchanged after a firmware update. |
| Reset User Configuration | A bug has been fixed that occurred after deleting the user.json (User Configuration) prevented the creation of an initial user via the API. |
| Modbus Driver Interface Selection | The selection of RS232 and RS485 interfaces in the Modbus driver has been corrected. |
| Availability Test Button | The Test button is displayed correctly as disabled (grayed out) when multiple data points are selected at the same time. |
| HTTPS Certificate Name | The incorrect term “HTTP Certificate” has been corrected to “HTTPS Certificate.” |
| Transmission of Profinet Data Point Values | An error in the transmission of value changes between a PLC and the XT gateway has been fixed. Value changes are now reliably transmitted, even when different Profinet data point types are used. |
