gazza29 Posted September 14, 2021 Report Share Posted September 14, 2021 Looking for best way to set up a tank level monitor on hmi and ladder in unilogic using 4-20ma any examples out there new to all this Gary Quote Link to comment Share on other sites More sharing options...
MVP 2014 Simon Posted September 14, 2021 MVP 2014 Report Share Posted September 14, 2021 Simple Tank Monitor.ulpr Hi Gary, try the attached. The setup is quite simple, this one allows you to enter the level range from the front screen of the HMI, rather than hardcoding it into the logic of the PLC. Hope it helps, Simon Quote Link to comment Share on other sites More sharing options...
pascal Posted November 30, 2021 Report Share Posted November 30, 2021 just found out : in properties of your 4..20mA input, you can determine the values of 4 and 20 mA -> if in your setup 4mA = 0% and 20mA=100%, then you just put these numbers in the properties, so unilogic itself is calculating everything for you 😁 in my example -> 4mA = 4900 and 20mA=1400..... (measuring the filling height seen from the top of a tank - my sensor returns not 4..20mA but 20..4mA) Quote Link to comment Share on other sites More sharing options...
