Restriction for device family 0BA4
The Gain cannot be a negative value.
Calculation with the device families 0BA0 to 0BA3
With LOGO! devices from these device families, LOGO! adds or subtracts the parameter offset to or from the standardized value before multiplying the value with the parameter gain.
Therefore, the following formulas apply:
Analog value = (standardized value + offset) x (gain x 100)
Gain (in percent) = (maxSensor - minSensor) / [(maxnorm – minnorm) x 100]
Offset = [(minSensor x maxnorm) – (maxSensor x minnorm)] / (maxSensor – minSensor)
Gain (in percent) = minSensor / [(minnorm + offset) x 100]
Offset = [maxSensor / (gain x 100)] - maxnorm
Gain
This parameter is given in %.
The Gain cannot be a negative value.
Zero point offset
You can enter values between -999 and +999 for the zero point offset.
