First steps using Labview with an PLC Arduino
Controlling a digital PWM Output with Labview
In this first example, we will control a digital output of our industrial PLC from Labview. For this, we have chosen a digital output with PWM to be able to modify the clock cycles from the Labview interface by creating our own application.
In this first example we have used an M-Duino 21+, but the following industrial Arduino PLCs can also be used to perform the same example (check the user guide to see which Arduino pins are related to a PWM output of your PLC).

Preparing the environment
We will use Labview to help us program graphically in a simple way. In addition, you have got integrated and specific libraries for engineering software functions and hardware interface and features for analysis, visualization and data sharing among other options.
We will use the tools provided to control our Arduino-based PLC from the monitor of our PC with the graphical interface that we are going to create. National Instruments offer us the Arduino toolkit for Labview, which we have already downloaded in the previous Labview post.
