ConfigError:
0 = ConfigOK, 1 = ConfigError
APF:
0 = AS-i Power OK, 1 = AS-i Power Fail
PeripheryFault:
0 = PeripheryOK, 1 = PeripheryFault
ConfigurationActive:0 = ConfigurationActive, 1 = ConfigurationInactive
Offline:
0 = Online, 1 = Offline
LOS-Master-Bit
0 = Offline by ConfigError deactivated
1 = Offline by ConfigError activated
A rising edge of F2 and F3 switch the master to the desired mode.
A rising edge of the "LOS master bit" effects that all bits in the
LOS
are set. A falling
edge effects that all bits are deleted.

EC-Flags and AS-i watchdog
In addition to EC flags, the AS-i watchdog flags will be transferred in diagnostic
data too.
Diagnostic data are assembled as follows:
ec-flags (high):
Bit 0:
periphery fault
Bit 1 … Bit 2 reserved
Bit 3:
failure redundant 24 V (option single master)
Bit 4:
earth fault
Bit 5:
over voltage
Bit 6:
noise
Bit 7:
duplicate address
ec-flags (low):
Bit 0:
configuration error
Bit 1:
slave with address0 detected
Bit 2:
Auto_address_assignment not possible
Bit 3:
Auto_address_assingment available
Bit 4:
configuration mode actice
Bit 5:
not in normal operation
