Module 4:
Content
:
Only AC1326:
binary inputs and outputs of B-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

..
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 2. (For more about this subject see module 1.)
Module 5:
Content
:
multiplexed analogue inputs of AS-i master 1 and 2

SSSSS:= 5 bit slave number 1..31
CC:= 2 bit channel No. 0..3
to calculate: (slave No.) + (master No. * 64) + (32 if B-Slave)
2nd word: not used
AS-i DP -Gateway response:
1st word: MMXSSSSS EEEE00CC (copy of request)
EEEE:= 4 bit error No. of response: 0=OK, 1=not valid,
2=Overflow, 4=no active analogue slave.
2nd word: analogue value, INTEGER
