Error code
A CS31 bus slave error is indicated by an error LED on the CS31 bus slave. The error LED
remains on even after elimination of the error and is switched off only after the error has been
acknowledged by the CS31 bus master.
The acknowledgment of a CS31 bus slave error can take place via the CS31 bus master by
means of the function block CS31QU_EXT (see AC500 documentation).
