Bit 5: not in normal operation
Bit 4: configuration mode actice
Bit 6: AS-i power fail
Bit 7: AS-i master is offline

Each element of the user diagnosis (ec-flags and slave lists) can be switched off
by setting the appropriate bit in the parameter telegram.
Each element which is not used will be filled up with zeroes. This way the data el-
ements in the diagnosis telegram will keep its designated position (and clear text
diagnosis still fits to the data).
Only if an element at the end of the user diagnosis is not used, the length of the
diagnosis will be shortened.
ExtDiag will be set if at least one of the following conditions is fulfilled:
• ConfigError ≡ 1
• APF ≡ 1
• PeripheryFault ≡ 1
The conditions when to set the ExtDiag bit can be chosen using the user parame-
ters or the commands of the command interface.
The GSD file includes the following presettings:
• The diagnosis transmitts ec-flags, delta list and LPF.
• ExtDiag will be set if ConfigError = 1 and APF = 1. ExtDiag will not be set if there
is a periphery fault.
