You will need to provide more details of your problem; it is not clear exactly what you are trying to do. Also, you need to understand that this site does not provide code to order.

This is not a good question - we cannot work out from that little what you are trying to do.
Remember that we can't see your screen, access your HDD, or read your mind - we only get exactly what you type to work with - we get no other context for your project.
Imagine this: you go for a drive in the country, but you have a problem with the car. You call the garage, say "it broke" and turn off your phone. How long will you be waiting before the garage arrives with the right bits and tools to fix the car given they don't know what make or model it is, who you are, what happened when it all went wrong, or even where you are?

That's what you've done here. So stop typing as little as possible and try explaining things to people who have no way to access your project!

Use the "Improve question" widget to edit your question and provide better information.

A very simple step would be to buy a third-party support driver based on your choice of PLC and choice of protocols you select. If you are looking at a hard way [pun intended] then I would suggest you start learning a little more about how the PLC communication works. Anyways AdvancedHMI is one of the options that can make your life easy. Just google it, they have a very good forum and have all the basic drivers required to connect to multiple controllers.
