PLC Analog output analog output FB analog2nda (Mitsubishi FX3U)

Function block (FB)analog2NDA apply FX3U Series connection FX2N series 2DA modular , We use WR3A Instructions . There are multiple in the system FX2N_2DA When , We only need to instantiate multiple FB after , Modify unit number , Just call it directly . Analog acquisition FB See the following article ：

PLC Analog input Analog quantity conversion FB S_ITR（ Mitsubishi FX3U）_RXXW_Dor The blog of -CSDN Blog 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 analog collection library how to design , 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 fohttps://blog.csdn.net/m0_46143730/article/details/125555891
