device manual AS-i DP-Gateway
5.1.2 Device-specific Profibus DP parameters:
In order to define the addresses of the parallel analogue input and output slaves and to define
parameters of the connected AS-i slaves, up to 100 byte device-specific parameters have to be set:
Device-specific Profibus DP parameters (example):
Byte 1..4:
16#80, 16#00, 16#00, 16#00, (fixed device parameter)
Byte 5:
16#AE, (fixed value: start of analogue input addresses)
Byte 6..20:
16#42, 16#44, 16#45, 16#48, 16#50,... (slaves 2,4,5,8,16, ... of master 1)
Byte 21:
16#AA, (fixed value:start of analogue output addresses)
Byte 22..36:
16#41, 16#43, ... (slaves 1, 3, ... of master 1)
Byte 37:
16#2F (Bit 5 = 1 enables extended diagnostics of the AS-i systems via Profibus DP)
Byte 37:
16#1F (Bit 4 = 1 enables AS-i parameter download)
When using a single master AC1335:
Byte 37..68:
16#1F, 16#FF, ... (predefined parameters of the AS-i slaves)
When using a double master AC1326:
Byte 37..100: 16#1F, 16#FF, ... (predefined parameters of AS-i slaves)
Slave addresses in Profibus parameter bytes 6..20 and 21..36:
MMXSSSSS
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)
Examples:
16#43 : Master 1, slave 3(A)
16#85 : Master 2, slave 5(A)
16#61 : Master 1, slave 1B
16#5C: Master 1, slave28(A)
In the GSD file definitions have been created to make the parameter setting comfortable (if supported
by the configuration tool of the Profibus DP master):
5-28
