Pulse counting - Vision V700 + V200-18-E1B

Recommended Posts

I have looked for some basic information about pulse counting but I couldn't answer what i believe is a simple question?

I have some experience using the Vision series PLC for simple digital I/O and analog I/O. But I have a requirement to count pulse from a flow meter and plan to set up one of the inputs on the snap on module V200-18-E1B as a HSC linked to ML-95. 

I can make the connection to PLC direct or make a link between the flow meter device and the inputs to count the pulse with a PR Electronics 9202 pulse isolator. Then my scaled flow pulse should just increment ML-95. I am attaching some info on the flow meter compute pulse (max frequency 6.5hz. 

Just want to check I am understanding the function of the HSC input correctly.
