Communication information
Note
With AnIn Min, AnIn Max, AnIn Function Min and AnIn Function Max settings,
loss of feedback signals (e.g. voltage drop due to long sensor wiring) can be
compensated to ensure an accurate process control.
Example:
Process sensor is a sensor with the following specification:
Range:0–3 bar
Output:2–10 mA
Analogue input should be set up according to:
[512] AnIn1 Setup = User mA
[5131] AnIn1 Min = 2 mA
[5132] AnIn1 Max = 10 mA
[5134] AnIn1 Function Min = User-defined
[5135] AnIn1 VaMin = 0.000 bar
[5136] AnIn 1 Function Max = User-defined
[5137] AnIn1 VaMax = 3.000 bar
AnIn1 Operation [5138]
Communication information
If the input signal is unstable (e.g. fluctuation reference value), the filter can be
used to stabilize the signal. A change of the input signal will reach 63% on
AnIn1 within the set AnIn1 Filter time. After 5 times the set time, AnIn1 will
have reached 100% of the input change. See Fig. 99.
