Simulation in LOGO!Soft Comfort
With simulation in LOGO!Soft Comfort you can read the following values:
①
Physical value; the ranges are stipulated by the measuring range (3)
②
Standardized value
③
Measurement range
④
Analog value (after processing gain and offset)
⑤
Analog value on the analog output

Possible settings with LOGO!
If you directly program your circuit program on the LOGO!, then you can only enter the gain
and offset parameters. You can calculate the gain and offset as follows:
External value range min
External value range min
Sensor
- max
Sensor
:
Range of a physical quantity that the sensor can measure.
Standardized value range min
Standardized value range min
norm
- max
norm
:
Value range of the standardized values.
With sensors that provide 0 to 10 V or 0 to 20 mA, the standardized value range is 0 – 1000.
With sensors that provide 4 to 20 mA, the standardized range is 200 – 1000.
So for gain and offset it follows:
Gain = (max
With sensors that provide 0 to 10 V or 0 to 20 mA, the standardized value range is 0 – 1000.
With sensors that provide 4 to 20 mA, the standardized range is 200 – 1000.
So for gain and offset it follows:
Gain = (max
Sensor
- min
Sensor
) / (max
norm
– min
norm
)
Offset = [(min
Sensor
x max
norm
) – (max
Sensor
x min
norm
)] / (max
norm
– min
norm
)
If you have calculated either the gain or the offset in accordance with the formulas above,
you can then calculate the respective other value in accordance with the following formula:
Gain = (min
Gain = (min
Sensor
- Offset) / min
norm
Offset = (min
Sensor
– (Gain x min
norm
)
