TwinCAT3 error output
Errors under TwinCAT3 are output
- via the PLC or
- directly in the TwinCAT Event Logger.
The overview diagram below shows the general function of the Event Logger:
Default parameter definition
By default, errors are output to the PLC together with logging to the Event Logger via the original ChannelError function block.
If an existing CNC configuration is migrated from TwinCAT2 to TwinCAT3, the start-up parameters for error management require no adaptation in P-STUP-00167 (error_protocol_mode).

Error texts
With a CNC release, language-specific error texts are automatically installed by the TcCncErrors-xml file.
