Function
The input signals of this function block are copied to the 8 byte user data of the AIF object and laid
on the connected 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 of the function block STAT is mapped. Some of the bits are freely assignable
(see description function block STAT in chapter 7.6.70)
Byte 3 and 4
l
C0854 = 0
– The analog signal at AIF-OUT.W1 is output.
l
C0854 = 3
– The LOW WORD from AIF-OUT.D2 is output.
Byte 5 and 6
l
C0852 = 0
– The analog signal at AIF-OUT.W2 is output on byte 5 and 6.
l
C0852 = 1
– Bits 0 ... 15 of FDO are output.
l
C0852 = 2
– The LOW WORD from 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
– 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 on byte 5 and 6.
– For this, C0852 is set to 2. The phase signal at C0851 is output on byte 5 and 6.
l
For the digital signals, only the bits 16 ... 31 (byte 7 and 8) are available (byte 5 and 6 are
assigned):
– For this, C0853 is set to 1. Bit 16 ... 31 (FDO)are output on byte 7 and 8.
