Function
A function calculates a result according to the current value of its inputs. A function has no internal data and is not linked to declared instances. block - generate a PWM signal.
Inputs
| XIN : REAL | Input analog value |
| XinMin : REAL | Minimum input value |
| XinMax : REAL | Maximum input value |
| MinPulse : TIME | Minimum pulse time on output |
| Period : TIME | Period of the output signal |
Outputs
| Q : BOOL | Blinking PWM signal |
Remarks
The input value is truncated to [XinMin .. XinMax] interval. XinMax must be greater than XinMin.
The signal is TRUE during:
(Xin - XinMin) * Period / (XinMax - XinMin)
ST Language
PWM1 is a declared instance of PWM function block.
PWM1 (rIn, rInMin, rInMax, tMinPulse, tPeriod);
Signal := PWM1.Q;
