Hi.
I'm new to allen bradley PLC's and PLC's in general.
I've been asked to make a program that can determine the water flow of a machine. I have a HB-therm water heater that has a flow sensor connected to it and to the PLC's DI.
My question is, how do I determine the input voltage in the PLC? I figured that's the only way to determine the flow. When the sensor is at 24v/100Hz (Which is when the flow is at it's max), the flow is at max speed (15L/min) and vice versa with 0v. From there it's a simple calculation and few functions.
Any help is appreciated, since it's a pretty big task to do, as a beginner. Thanks in advance!
