CLICK PLC High Speed Inputs: Setup for Rate on a Single Input from AutomationDirect

Setting up High speed inputs and calculating the rate can be intimidating, but with CLICK it becomes just another simple function. This video shows how to setup to high speed inputs on a CLICK PLC for Rate calculation. To use High speed inputs on Click. You must have a Click CPU that supports Ethernet and has DC inputs. High speed counting is not supported on units with AC inputs. You must have CLICK Programming software 2.30 or higher and update the firmware to match this software version. I have an NPN inductive prox, that meets the voltage requirements of the CLICK PLC. I wire the output of the inductive prox to X1, and since this is an NPN prox, I will place positive 24 volts DC to the C1 common on the CLICK CPU. To start the setup, select the Function Tab. Select here on High speed input setup. Now, this display is what really makes the difference. It shows you exactly what each function does. Just check the graphic and then select the button that says, “Use this mode”. We are calculating rate so select here on Frequency measurement. First, I am going to give this function a Name. Select here to assign where the rate will be stored. I will use DD1. Now, this is a signed double integer so the range will be: Select the type as single input. Now, we need to assign the input for this function. Select here. Select X1. For rate you have two options, you have either Hz or Rotations per minute. Hertz is just a function of the amount of pulses per second. Were as, RPM is specific to your application. So, once I select RPM, you will notice that I am asked to enter a number. This is asking for the amount of pulses per one rotation of your process. For this example, I will use 360. Press Ok. Now you will see your rate function assigned here. Press Ok. And now here, you will see all of the registers that are assigned to this function. Let’s load this project into our CPU and test our rate. Open up a Data View. Add my rate register and then start the pulses. So, no more intimidation when it comes to setting up high speed inputs and calculating the rate. Just another way that CLICK makes advanced simple.
