Ft pt1
Type Function module¶
| Input IN | REAL (input signal) |
| T | TIME (time constant) |
| K | REAL (multiplier) |
| Output OUT_MAX | REAL (upper output limit) |
| FT_PT1 is an LZI- Transmission link with a proportional transfer behavior 1 Order, even as a low pass filter 1 order referred to. The multiplier K sets the gain (multiplier) is fixed and T is the time constant. A change at the input is attenuated at the output visible. The output signal increases within T to 63% of the input value and after 3 * T to 95% of input values. Thus, after an abrupt change of the input signal of 0 to 10 at the time of the initial input change 0, increasing to 1 at T * 6.3 and after 3 * T 9.5 and then approaches asymptotically the value 10. The first time the output OUT to the IN input value is initialized to a defined starting performance guarantee. If the input T of T#0s is equal to the output OUT = K * IN. |
