device manual AS-i DP-Gateway
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 master 2 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 2. (For more about this subject see module 1.)
Module 5:
Content: multiplexed analogue inputs of AS-i master 1 and 2
Length: 2 word consistent I/O (=0 if not used)
DP master request:
1st word: MMXSSSSS 000000CC
Bit:
15 14 13 12 11 10 9 8 7 6 5 4 3 2 1 0
MM X SSSSS 0 0 0 0 0 0 CC
MM:= 2 bit master number 1..2;
X:= 0=A/Single, 1=B-Slave;
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
5-18
