Table: Master flags
12475
Bits 12...15 of the first word of the digital input data contain the master flags. They provide information
on the operating state of the AS-i master. The following table shows the meaning of each bit:
Bit 15
Bit 14
Bit 13
Bit 12
AS-i power fail
(19 V)
Configuration error in the
AS-i circuit
AS-i master is offline
(AS-i data is invalid)
Periphery fault in the AS-i
circuit
Possible values per bit:
0 = no error
1 = error
In the digital output data, bits 12...15 have no relevance and are not evaluated!
