C# realizes the communication technology between host computer and PLC

1. Download and install Mitsubishi MX COMPONENT

2. Communication test and data monitoring
Open the PLC monitoring program:

You can see the previously set communication configuration and reset it:

Click OK

On the right side, you can enter the address to monitor the PLC data.

PS: 1: plc address, 2: start and end monitoring, 3: change monitoring mode

Buffer memory monitoring

You can also perform customized monitoring based on the input address

Write data to PLC and set PLC time

You can write bit by bit or write multiple bits at a time

3. Many people started looking for the source code of the communication. I also searched for a long time at the beginning. The annoying thing is that some people not only do not provide the source code but also charge gold coins for downloading. I draw a circle here. Generally, this kind of software comes with the source code. I don’t believe that MX COMPONENT doesn’t have it. Finally, I found it in a corner. I feel very emotional...

Select the program and right-click Properties:

Select Open File Location in the Properties panel:

Find the folder where the program is located:

Return to the previous directory:

Enter the samples folder (finally found the C# source code, haha):

You can refer to the source code for testing.

Here I will tell you how to build your own project:
create a new C# form application, add a reference, and find that there is no dll in the case program.

Select Tools in the menu bar and click the Toolbox item in the drop-down box.

Select the com component tab and check the controls you need in the selection interface.

You can see the mx controls in the general items in the toolbox!
