I have done several machine and process control projects using a PLC with a touchscreen type HMI such as units available from Total Control and many others. I know it is possible to use a PC as the HMI and would like to learm more about doing this. My basic objective here is to use a PC as the HMI for control and monitoring just like would be done with an off the shelf HMI.
My present knowledge and understanding of doing this is very limited and I don't expect to get an education here. I would like to get answers to a few basic questions and perhaps links, etc. to more detailed information.
I know that PLC manufacturers offer software packages to do this but that is not an option for me. The ones I have looked at are far too expensive for what I'm doing. I believe this can be done using Visual Basic or something similar. Am I correct about that? Point me in the right direction please.
