SCALE_B4 calculates from the input values IN and the setup values IN_MIN and IN_MAX internal values, then add all the internal values, multiplies the sum by K and add the offset O. An input value IN = 0 means IN_MIN is included, IN = 255 means IN_MAX is not considered. If K is not connected, then the multiplier is 1 |
| OUT |
= (in1 * (IN1_MAX – IN1_MIN) / 255 + IN1_MIN |
|
+ in2 * (IN2_MAX – IN2_MIN) / 255 + IN2_MIN |
|
+ in3 * (IN3_MAX – IN3_MIN) / 255 + IN3_MIN |
|
+ in4 * (IN4_MAX – IN4_MIN) / 255 + IN4_MIN) * K + O |

SCALE_B4 can ie be used for calculation total air quantities in ventilation systems, or wherever controlled mixers are used and the resulting total needs to be calculated.. More detailed explanations you can find at SCALE_B2. |
