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 the parameter offset is added or subtracted to or from the standardized value before the value is multiplied with the parameter gain.
Hence, 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
Here you can enter values between -999 and + 999.
