All Slaves Failed	All Slaves Failed = true Bus startup failed for all slaves. No slave has reached the ESM state requested by the master.
Distributed Clocks Failed To Lock	Distributed Clocks Failed To Lock = true The master failed to synchronize the distributed clocks (DC) of the slaves.

The "Runtime" structure provides possible error causes during ongoing bus operation:

Detected Collective Inconsistence	Detected Collective Inconsistence = true At least one slave is not in the bus state specified by the master.
Detected All Slaves Unreachable	Detected All Slaves Unreachable = true The master does not reach a slave on the bus.
