Title: Question about BRX encoders and Speed Display
Post by: DefenderY on November 26, 2024, 12:21:17 PM

Hello,
I am new at this software and I have been trying to display speed on an HMI that I have installed in a machine. The machine has an encoder x0,x1,x2 are my high speed inputs on the PLC. I tried configuring quadratic encoder along wit the MOVE, MATH, ant timers but it does not work correctly.

Do you have an easy way to do this ? I just need the speed of copies per hour displayed on an HMI. I already have The HMI setup for it

Thanks

If they are quadrature encoders, you'll need at least 2 inputs, Count A and Count B, so say X0 and X1 for the first encoder. The remaining X2 input does something else, and may or may not be needed for your application.

You can find the value in the $DeviceName.Acc (or ScaledValue, etc) in a Data View to get a feel for how the numbers look before you massage them with MATH, etc.

Thanks, yes I have everything connected. I was able to solve the issue by experimenting. Thanks again
