7.3.1 Status Flag Bytes - Byte 1 (Low byte of word 26)
7.3.2 Status Flag Bytes - Byte 2 (High byte of word 26)
Bit Description
7 ASI CONFIG OK. If this bit is 1, the configuration stored in EEPROM
matches the current configuration
6 ASI LDS 0. If this bit is 1, the slave with address 0 exists
5 RESERVED
4
ASI AUTO PROG AVAILABLE. If 1, Auto Address Programming is
possible at this moment. This means a slave has failed and can
immediately be replaced with a new slave of same ID and I/O at
address zero. The new slave will be automatically re-addressed.
3 ASI OPERATION MODE. 0 is Protected mode, 1 is Configuration Mode
2 ASI NORMAL OPERATION. If 1, the network is operating normally
1 ASI POWER FAIL. If 1, voltage on AS-Interface line is too low
0 ASI OFFLINE. If this bit is set to 1, it causes an error 75h. Usually, this
is cause by having an extra slave at address zero.
Bit Description
7 - 4 RESERVED
3 ASI AUTO ADDRESS ENABLE. If 1, Auto Address Programming is
enabled. This means if a slave should happen to fail, it can be replaced
with a new slave via Auto Address Programming.
2 ASI EEPROM OK. If 1, the configuration EEPROM is OK (there is
something stored in EEPROM)
