IR n.02 Normal_Operation Flag
0 Master is not in Normal Operation.
The AS-Interface master is not executing cyclic data ex-
changes with its slaves.
1 Master is in Normal Operation.
The master executes the AS-Interface cycle of Data Ex-
change, Management and Inclusion Phases.
See also 1-1-3, Technical Details.
IR n.03 Configuration_OK Flag
0 Configuration Error.
At least one mismatch exists between the permanent
configuration data and the slaves actually detected on the
network.
1 Configuration is OK.
The actual configuration matches the configuration data
stored in non-volatile memory, i.e. all detected slaves have
an ID code and I/O code as in the permanent configuration
data.

IR m.00 Auto_Address_Disable Bit
0 Auto Addressing is enabled.
When the AS-Interface master is in Protected Mode, it is
possible to replace slaves on-line by 'blank' slaves (address
0) with the same ID- and I/O codes.
1 Auto Addressing is disabled.
IR m.01 Mode Control Bit
0 Standard Modes
Requests the master to operate in Configuration / Protected
Mode, depending on the position of the MOD switch.
1 Setup Mode
Requests the master to operate in Setup Mode. This request
will only be granted when the MOD switch is OFF.
After setting this bit, always check IR n.00 (Mode Flag) to
determine the actual operating state of the master. If the master
is set to Protected Mode by the MOD switch, setting the Mode
Control Bit to Setup Mode will have no effect.
