Function-extension:
When exporting the binary logbook (extended diagnostics for Lenze development) via device command (0x2022:036), additional log information is now provided in JSON file format.
This log information can be used for 3rd-party visualizations, for example.
In a JSON file, for each logbook entry next to the error code also includes the timestamp from the time of Appearance and the severity of the error message saved.
Error texts are not included in the JSON file. However, these can be generated using the export function in Easy-Starter and exported to a text file:
Export => error texts *.txt.
- device command (0x2022:036): spokes / Overwriting the JSON file.
- Device command (0x2022:037): Delete the already stored JSON file.
The JSON file is stored next to the binary logbook under the following directory filed: ("/tmp/user_data/"). Size: Maximum 1000 entries.
Example for JSON data:
[ {
"LogEntryNumber": 1,
"Timestamp": 1727980437,
"Severity": 11,

{
"LogEntryNumber": 2,
"Timestamp": 1727980439,
"Severity": 2,
"ErrorID": "0x20094381"
},
