(scaling)
The settings in the Scaling dialog have a direct impact on the process value.
Scaling is carried out for each channel and is saved permanently, i.e. available
after restarting the node.
Figure 23: Scaling parameters
To select the process value for the respective channel, select the
[Channel 1] ...
[Channel (2) 4]
radio button.
To display the value in hexadecimal format, select the
[hexadecimal]
radio
button.
To display the value in decimal format, select the
[decimal]
radio button.
To switch on manufacturer scaling, select the
[Manufacturer scaling]
radio
button. When manufacturer scaling is ON, the process value appears scaled in
1/10 °C or Ohm per digit. When manufacturer scaling is OFF, the process value
appears scaled 1/16 °C or Ohm per digit.
For sensor types with ineffective manufacturer scaling (resistance ... 5 kOhm),
the process value appears scaled in 0.5 Ohm per digit.
To switch on user scaling, select the
[User scaling]
radio button. When user
scaling is ON, the signal charge can be viewed immediately after the
manufacturer scaling. The
Offset
and
Gain
fields involve linearization according
to the formula of a linear equation:
f(x) = mx+b
