device manual AS-i DP - Gateway
The AS-i ma
ster status information in the first byte of the digital inputs of the single /A slave data (byte
0, bit 4..7) contains the master flags of the respective AS-i system:
Bit7 Bit6 Bit5 Bit4
reserved configuration error in
AS-i system
no AS-i slave detected periphery fault
The AS-i master control information in the first byte of the digital outputs of the single/A slave data
(byte 0, bit 4..7) controls the stored diagnostic information:
bit7 bit6 bit5 bit4
reserved reserved reset the stored diagnostic
data
activate transfer of the stored
diagnostic data
If bit 4 of the control information is TRUE, the AS-i DP -Gateway transmits the stored periphery and
configuration error in the device-specific diagnostics. The flags remain TRUE even if the error is no
longer present. Bit 5 in the control information resets this information.
More information on this subject is to be found in the paragraph "AS-i diagnostics".
Module 2:
Content: Only AC1326: binary inputs and outputs of Single- or A-slaves of AS-i master 2
Length: 0..16 Byte I/O (=0 if not used)
Byte No. Bits 4..7 Bits 0..3
1 flags master 2 Slave1 (a)
2 Slave2 (a) Slave3 (a)
..
15 Slave28 (a) Slave29 (a)
16 Slave30 (a) Slave31 (a)
The flags in the first input byte contain status information, the flags in the first output byte contain
control information refering to AS-i master 2. (For more about this subject see module 1.)
Module 3:
Content: binary inputs and outputs of B-slaves of AS-i master 1
Length: 0..16 Byte I/O (=0 if not used)
Byte No. Bits 4..7 Bits 0..3
1 flags master 1 Slave1b
2 Slave2b Slave3b
..
15 Slave28b Slave29b
16 Slave30b Slave31b
The flags in the first input byte contain status information, the flags in the first output byte contain
control information refering to AS-i master 1. (For more about this subject see module 1.)
