PLC Analog input analog conversion FB s_ ITR (Mitsubishi FX3U)

Analog acquisition （ Linear sensor ） See the following blog post for the mathematical principle of ：

PLC Analog acquisition linear function (y=kx+b)_RXXW_Dor The blog of -CSDN Blog How to design analog acquisition Library , For the specific algorithm code, please refer to another blog post ：PLC Analog input Analog quantity conversion FC：S_ITR_RXXW_BOSS The blog of -CSDN Blog _s_itr Analog acquisition 、 It is widely used in industrial field 、 The measured value and output signal of most sensors are linear , So we can use linear function to directly convert , Not much to say , Direct drawing and code S_ITRScale Integer to RealThe formula is as follows:Ov = [(OSH - OSL) * (Iv - ISL) / (ISH - ISL)] + OSLwit.....https://blog.csdn.net/m0_46143730/article/details/124910267
