Hello Franck;

The S7-1214C can use its first 6 input as high-speed counters (HSC), with a max. frequency of 100 kHz on the first 2 HSC. The screenshot below, from the datasheet of the S7-1214C AC/DC/RLY, confirms this. This document provides details on the S7-1200 HSC:

There are many posts on the forum discussing the connection of a pulse flowmeter with HSC inputs of a S7-1200. This one points to example applications that you could find useful; if you want to look at more discussions, use the search box at the right of this page.

Good evening Mr Chartier,

Attached you will find the program that I wrote. I request your assistance in making it operational. I included the flow meter specifications in network 1 of my code. Thank you for helping me, any other help from a third party would also be appreciated, it would help me to orient myself better.

Sincerely.
