B.3 B.3 Channel-specific diagnostics data, starting at byte 8
Introduction
Data record 1 contains the channel-specific diagnostic data, starting at bytes 8 to 15. The
figures below show the assignment of the diagnostics byte of a module-specific channel or
channel group. General rule: An error is indicated by a logic "1" at the relevant bit.
For information on possible error causes and troubleshooting routines, refer to the chapter
"Module diagnostics."
