Function
Theinput signals ofthisfunctionblock arecopied to the8byteuserdataof theAIFobject and applied
to the plugged-in fieldbus module.
Bytes 1-2 and bytes 3-4
It is possible, using different variables, to write simultaneously to bytes 1-2 or bytes 3-4. Avoid this
situation, since the data in bytes 1-2 or bytes 3-4 are then not unambiguous.
The variables ... write data simultaneously to ...
AIF2_nOutW1_a
Byte 1 and 2
AIF2_bFDO0_b ... AIF2_bFDO15_b
y
e
a
d
AIF2_dnOutD1_p
AIF2_nOutW2_a
Bytes 3 and 4
AIF2_bFDO16_b ... AIF2_bFDO31_b

a
d
AIF2_dnOutD1_p
Example:
If you write to bytes 3-4, using the variables
AIF2_nOutW2_a and AIF2_dnOutD1_p then bytes 3-4
will be rewritten every time a variable is processed. The data in bytes 3-4 arethus not unambiguous.
Byte 5 and 6
You can freely link bytes 5 and 6 with variables of the corresponding data type, as a 16-bit data word
(quasi-analog signal).
Bytes 7, 8
You can freely link bytes 7 and 8 with variables of the corresponding data type, as a 16-bit data word
(quasi-analog signal).
Address range from byte 1 - 7
Byte Address
1, 2 %QB42.0 and %QB42.1
3, 4 %QB42.2 and %QB42.3
5, 6 %QB42.4 and %QB42.5
7, 8 %QB42.6 and %QB42.7
