Dear All,
I’m using S7-300. I need to scale an output value for a valve open control. I have an I/O field on my SCADA (WinCC v6.0) where an operator inputs value between 0% and 100%, which is the percent of the valve open, 0% for 4 mA and 100% for 20 mA. I’ve tried to use FC105 and FC106, but in both cases I have 0 on the OUT. I’ve also tried to write the formula from these functions’ “help” manually, but the result was same (zero on the “out”). I’d like to know what I am doing wrong.
Thanks in advance and Best Regards!
