Hi All,
I need your help in this task
I have to read (visualise) the output of a flowmeter in kg/s on an HMI screen (before I use it in a flow control loop to adjust a valve).
The problem is it's a pulse output so I'm a little bit confused since I've been always working with analog sensors output (0-10V/4-20mA...) using SCALE/UNSCALE
Do I need to use a counter for pulses ?
What I/O module to use in HW config ?
I am using Siemens Step 7 v5.5
315 CPU
Thank you.
