Diagnostics
The module offers various diagnostic options for users. These messages are divided into hardware warnings and hardware errors. The respective status words for the channels (except digital inputs and outputs) contain a bit for warnings and errors. The exact cause is analyzed via the diagnostic data (0xA050). Warnings are reset automatically. Errors may result in the output stage being switched off (PWMi) and have to be acknowledged in the control word (0x7050:07 Reset)
