CJ1M-CPU23 Reading a square wave

2 posts in this topic

Hello,

I have a flowmeter (macnaught flowmeter) which says that it outputs a 2 square waves. I am unsure how to connect the flowmeter to my plc (CJ1M-CPU23), do I need an additional unit or can I use the general purpose IO things mentions in the manual (IN6-9 say they are high speed counters)? Any advice would be appreciated.

Thanks,

Jay

Depending on the pulse frequency, you should be able to use the CPU23 high speed counter inputs.

Check the W395 manual for specific information on the built in I/O.

Hope this will help.
