Hello everyone.
I was wondering if I could get some help with a project that been push onto to me this past week. My background is in computer science and I'm more at home getting a pointer to video memory and drawing my interfaces that way then going through all these hoops.
We have a HMI device (MT8070iE) which meets our explosive testing requirement. I have the HMI device connected to a switch. A PC is also connected to this switch as well.
I was wondering if there is any way to talk to the HMI programmatically via TCP/IP using the computer or small SOC (system on a chip)?
For example, opening a port and changing the value of the bar chart. Please point me to a tutorial online (if any) that can get me started.
So far, I have done this using the EasyBuilder Pro that came with the HMI.
And I was unable to deploy it just fine over Ethernet.
What I want to do is to be able to change the value of the vertical bar chart from the computer that is on the switch. I have added a MODBUS TCP/IP (PLC) to the project and pointed the IP address to the computer on the switch. But not quite sure if it should be a MODBUS Server instead? I have also changed the address of the bar chart to "RW" and 2000.
Currently, I'm stuck and the getting started PDFs and other online resources I have found are not helping me in this regard. I'm currently looking at the MODBUS protocol but it might be reinventing the wheel if I were to write it myself.
Thanks again.
