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.
Assignment of REB500 channels to IEC 60870-5-103 channel numbers:

Diagnostic information
Status and diagnostic information is generated by the various REB500 application
software modules and transferred spontaneously as events every time the status
changes. A separate group exists for diagnostic information with an entry for every
subsystem of the REB500 system software REBSYS.
Diagnostic event group:
