The 369 Motor Management Relay supports both slave mandatory (6 bytes system-wide
standardized) and slave specific diagnostic data. If the diagnostics are considered high
priority, the PLC/host program will be informed of the fault (alarm or trip) and can call a
special error routine.
Diagnostic bytes 1 through 6 represent standard diagnostic data and are formatted as
follows.
