device manual AS-i DP - Gateway
Module 6:
Note: If the analogue outputs are also driven by module 10 the output values of module 6 are
overwritten by the values of module 10.
Content: multiplexed analogue outputs of AS-i master 1 and 2
Length: 2 word consistent I/O (=0 if not used)
DP master request:
1st word: MMXSSSSS 000000CC
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: analogue value, INTEGER
AS-i DP -Gateway response:
1st word: MMXSSSSS EEEE00CC (copy of request)
EEEE:= 4 bit error No. of response: 0=OK, 1= invalid,
2=Overflow, 4=no active analogue slave.
2nd word: analogue value, INTEGER (copy of request)
Module 7:
Content: command channel
Length: 4 byte consistent I/O (=0 if not used)
DP master request:
1st byte command No.
2nd byte: MMXSSSSS (as far as necessary; see table below)
MM:= 2 bit master number 1..2;
X:= 0=A/Single, 1=B-Slave;
SSSSS:= 5 bit slave number 1..31
to calculate: (slave No.) + (master No. * 64) + (32 if B-Slave)
3rd to 4th byte: data; see table below
AS-i DP -Gateway response:
1st byte command No. (copy of request)
2st byte: MMXSSSSS (copy of request)
3rd to 4th byte: data; see table below
