If clipping of output is also required, simply check if scaled output is in range. and this is easy because equation only uses basic math operations which are available on every controller.
Now you can use PLC of your choice to implement that equation. universal formula for linear scaling with parameters. Out = (in-in_low)*(out_hi-out_lo)/(in_hi-in_low) + out_lowĪnd that's it. Then substitute in previous m expression to get: The only thing left is to combine everything and you get the universal linear scaling formula where domain and range can be simple to parametrize. There are different ways to go about this, depending on specific application needs, or computational optimization but assuming one wants generic universal scaling with parameters and without clipping, one may proceed as follows:Īnd knowing basic linear equation in intercept formįor line, slope is simply change of Y over change of Xīut can also be expressed relative to "in" and "out": just quickly adapt library and my programs will run on any controller. this way i don't care what the target platform is. in tend to roll my own functions because i don't like incompatibilities that specialized instructions bring. it is easy to do on any platform using nothing but high school math. The first category is in the form of setup files (.exe) for each PLC training course. Mitsubishi provides two types of e-learning materials on PLC basics and programming.
#GX WORKS 2 ANALOG FREE#
This is a very common and straight forward task. Mitsubishi offers free PLC programming courses for automation engineers to learn about the PLC basics, industrial networks, types of products, and PLC software. The signal is 4-20mA and the range of i would like to have 0-100PSI, i cant seem to find any scaling on the manual. i am not impressed how easily people get "stuck". Hi, im pretty new to the programming environment of the GX works 2 and i would like to do scaling of my analog signal from Q64AD module.
