Function
The input signals of this function block are copied into the 8-byte user data of the AIF object and
assigned to the 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 thefunction block STATis mapped. Some of the bits are freely assignable
(see description of the function block STAT in chapter 9.2.61)
Byte 3 and 4
z C0854 = 0
– The analog signal at AIF-OUT.W1 is output.
z C0854 = 3
– The LOW-WORD of AIF-OUT.D2 is output.
Byte 5 and 6
z C0852 = 0
– The analog signal at AIF-OUT.W2 is output to bytes 5 and 6.
z C0852 = 1
– The bits 0 ... 15 of FDO are output.
z C0852 = 2
– The LOW-WORD of AIF-OUT.D1 is output.
z C0852 = 3
– The HIGH-WORD of AIF-OUT.D2 is output.
Byte 7 and 8
z C0853 = 0
– The analog signal at AIF-OUT.W3 is output.
z C0853 = 1
– The bits 16 ... 31 of FDO are output.
z 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:
z TheoutputofLOW-WORDofAIF-OUT.D1isonlypossibleonbyte5and6.
– For this purpose, C0852 is set to 2. The phase signal at C0851 is output to the bytes 5 and
6.
z 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 to bytes 7 and 8.
