Hello Community,
I am new to ctrlX PLC CXAC_Diagnostics library.
I saw this example how should i declare MyPendingDiagnostics and MyDiagnostics.
or is there any example to use the CXAC_Diagnostics library.
Warmest regards,
How to use CXAC_Diagnostics?

See online documentation for the library CXAC_Diagnostics and my hints and example below.
- See online documentation for a description of the diagnostic code
- Test.json file needs to be at "ActiveConfiguration/plc/run/linux-gcc-x64/data" and can be put there via ctrlX PLC Engineering or WebDAV
- Only reset errors can be cleared and warnings do not need / cannot be cleared
- Problems in verison 1.18:
- Function "UnregisterDiagnostics" has no function
- Fuctions "SetDiagnostics" and "ResetDiagnostics" give back an error even when function was executed properly (still investigating this)
- The Pending error list will always show one item more then actually visible in the ctrlX CORE WebUI
Test.json:
