Ok, as per title I have had a couple of HMI kicking around for ages that I managed to pick up cheap. This is the kind of stuff I do for my day job, so it’s not too tricky a project for me to tackle but maybe interesting for others to see how it’s done...
I originally got them to have a mess around with but decided one might as well be put to some use so it is going to be set up as a display for my VFD that my lathe runs on.
The HMI themselves are Samkoon HE 043 - a small colour touchscreen with one serial communications port. This port will be used to communicate with the drive (Schneider ATV 313 1.5kw) via a protocol called Modbus. This allocates a set of “registers” to values within the drive (or whatever you are communicating with) that allows you to view or write to them.
The idea being that I will get the HMI to display stuff like amps, frequency, drive &motor thermal state, alarms etc. Completely unnecessary but a mildly interesting diversion from other stuff!
