PLC Mitsubishi High Speed Counting

5 posts in this topic

Dear friends,

I want to calculate the flow with the help of a flow sensor that has 650 pulses per litre.

My question is that can i do that with the help of plc FX1N ? can plc count such fast pulses and how .. need some help

Use C235 and X0 as your count input.

Don't use X0 in your program though, that counter looks at signals on that input.

Also do not use inputs X1 nor X2.

650 pulses per litre is not a flow rate.

Well, if it flows e.g. 1 liter a minute, then you can basically go with any input on the PLC. They can all take 10.5 pulses/sec. You need to provide more (realistic) information if you want a realistic answer.
