Function
Theinput signalsofthisfunctionblockarecopied tothe8byteuserdataoftheAIFobject and applied
to the plugged-in fieldbus module.
Byte 1 and 2
Byte 1, 2 can be used as word information.
Bytes 3 and 4
You can freely link bytes 3 and 4 with variables of the corresponding data type, as a 16-bit data word
(quasi-analog signal).
Bytes 5-6 and bytes 7-8
It is possible, using different variables, to write simultaneously to bytes 5-6 or bytes 7-8. Avoid this
situation, since the data in bytes 5-6 or bytes 7-8 are then not unambiguous.
The variables ... write data simultaneously to ...
AIF1_nOutW2_a
Byte 5 and 6
AIF1_bFDO0_b ... AIF1_bFDO15_b
AIF1_dnOutD1_p
AIF1_nOutW3_a
Bytes 7, 8
AIF1_bFDO16_b ... AIF1_bFDO31_b
AIF1_dnOutD1_p
Example:
If you write to bytes 3-4, using the variables
AIF1_nOutW3_a
and
AIF1_dnOutD1_p
then bytes 7-8
will be rewritten every time a variable is processed. The data in bytes 7-8 arethus not unambiguous.
Address range from byte 1 - 7
Byte Address
1, 2 %QB41.0 and %QB41.1
3, 4 %QB41.2 and %QB41.3
5, 6 %QB41.4 and %QB41.5
7, 8 %QB41.6 and %QB41.7
