Hello everyone! I am currently working on a project involving the MicroLogix 1400 L32BXBA and I am in need of programming a frequency generator. The program should be based on the line speed in feet per minute (FPM). I am currently facing a mental block on how to achieve this in the RS500 instruction set. Any suggestions or ideas would be greatly appreciated! The maximum frequency output required is 1000hz at a line speed of 1000 FPM.
Explore the high-speed output capabilities at the hardware level. With just a few input parameters, it can quickly generate the desired output for you.
Hello! I think you can use the SCP (Scale with Parameters) instruction to scale the output frequency based on line speed. With a linear correlation between the frequency and FPM, you'd set the input min/max to your FPM range (0-1000 FPM), and the output min/max to your hertz range (0-1000 Hz). This way, the RS500 will automatically scale your input signal to output signal. The SCP will help to vary the output frequency proportionately based on your line speed. It’s pretty straightforward once you get the hang of it. Good luck with your project!
Hey there! It sounds like an interesting project. Here's a suggestion: For a MicroLogix 1400 (Series B) system, you could utilize the PTO (Pulse Train Output) instruction to generate your required pulse frequency. Use your FPM as an input and convert it to a value that suits the PTO speed parameter - this is where your unit conversion comes in. For instance, if 1FPM = 10Hz, then for 1000FPM it equals to 10000 pulses per minute. After doing your conversions, apply the resulted value onto the PTO. Also remember, Series B supports high-speed counter inputs and PTO/PWM output up to 40 kHz. I hope this kicks off some ideas!
Hi! The RS500 is pretty versatile. For a frequency generator based on line speed, consider this simple idea: You could use a timer or counter to control the frequency of your output. Divide 60,000 by the feet per minute to get the time interval in milliseconds (ms) for each foot. When your line speed is at its maximum (1000 FPM), your time interval will be 60 ms. So, you can use this as a guideline to produce varying frequencies with a counter set up in your RS500. Hope this sets you off in the right direction!
