3.5.4 Automation interface (AIF−OUT)
3−101
l
EDSVS9332P−EXT DE 2.0
Function
The input signals of this function block are copied into the 8−byte user data of the AIF object and
assigned to the plug−on fieldbus module. The meaning of the user data can be determined very easily
with C0852 and C0853 and the corresponding configuration code (CFG).
Byte 1 and 2
Here, the status word from the function block STAT is mapped. Some of the bits are freely assignable
(see description of the function block STAT in chapter 3.5.60)
Byte 3 and 4
l C0854 = 0
– The analog signal at AIF−OUT.W1 is output.
l C0854 = 3
– The LOW−WORD of AIF−OUT.D2 is output.
Byte 5 and 6
l C0852 = 0
– The analog signal at AIF−OUT.W2 is output at bytes 5 and 6.
l C0852 = 1
– The bits 0 ... 15 of FDO are output.
l C0852 = 2
– The LOW−WORD of AIF−OUT.D1 is output.
l C0852 = 3
– The HIGH−WORD of AIF−OUT.D2 is output.
Byte 7 and 8
l C0853 = 0
– The analog signal at AIF−OUT.W3 is output.
l C0853 = 1
– The bits 16 ... 31 of FDO are output.
l C0853 = 2
– The HIGH−WORD of AIF−OUT.D1 is output.
Example
You want to output 16 digital signals of FDO and the LOW−WORD of AIF−OUT.D1:
l The LOW−WORD of AIF−OUT.D1 can only be output at bytes 5 and 6.
– For this purpose, C0852 is set to 2. The angle signal at C0851 is output at bytes 5 and 6.
l For the digital signals, only the bits 16 ... 31 (bytes 7 and 8) are available (bytes 5 and 6 are
assigned):
– For this purpose, C0853 is set to 1. Bits 16 ... 31 (FDO) are output at bytes 7 and 8.
