The above Signal ID and Signal Text assignment for a specific Bay Unit can also be made via
HMI500 providing a COMTRADE file for the Bay Unit disturbance recorder is uploaded. The file
filename .cfg generated by the PC contains the same information as the list generated by the
export tool.
The assignment can change when the disturbance recorder configuration changes, for
example, by deleting or adding signals. The above list then has to be recreated and possibly
corrected by the control system.

ACC actual channel

The REB500 Bay Unit 500BU04 supports five voltage channels. Since, however, the compatible
range of the standard only lists four voltage channels, the fifth channel is transferred to the
private domain.
