8.8.7
Analog output range
This parameter is used to define the output current range.
Function code
Output current
0
0 … 20 mA
1 (default) 4 … 20 mA
8.8.8
Analog output source
The analog output can be used for a range of purposes. This parameter defines the tag that
controls the analog output.
Function code
Basis for the analog output
0
Gross weight (rounded according to DR 3)
1 (default) Net weight (rounded according to DR 3)
2
Tare weight (rounded according to DR 3)
3
Coarse/fine signal (specified percentage from DR 25)
4
Control using data record DR 17
5

This parameter defines the response of the analog output following a fault of the SIWAREX
module or SIMATIC STOP.
Function code
Response
0 (default)
Switch off
1
Retain function
2
Output configured substitute value (e.g. 3.5 mA)
3

8.8.10
Start value for the analog output
This parameter defines the start value of the scaling of the analog output and thus
corresponds to 0 mA or 4 mA, depending on the setting. The value can be greater or less
than the end value.
8.8.11
End value for the analog output
This parameter defines the end value of the scaling of the analog output and thus
corresponds to 20 mA.
