I'm an Electronics and Automation Engineer. I've done serial communications through Visual Basic with PLCs, HMIs and other Electronics Devices. My own designed software and hardware are running industrial machines via serial communication for years.
I've worked on SIEMENS, Delta, Fatek and other communication protocols for serial control and automation. Please have a look at my portfolio for software GUI samples.
As your detailed requirements are not mentioned and if there would be some unseen circumstances, we may negotiate project cooperatively. Thanks for your understanding. Please contact me at shahzad125[at]hotmail.com.
