Hi to all,
I am newbie in PLC and I have a project to do with Siemens s7 1200.
I have one Analog Input, IW1 which is 4 – 20mA from a flow meter and I want to represent it on HMI as m3/h with scale 0 – 1000 m3/h .
When the flow falls below 50% (500 m3/h) an indicator ‘’low flow’’ must be on.
I make some steps which I am not sure if are going to work (see attachment) and I don’t have any idea how to continue it and represent on HMI.
Please for a help!!!
