Advanced HMI - Using With TwinCAT

See how to get the Advanced HMI software to communicate with Beckhoff TwinCAT. If you are unfamiliar with either product, watch the "TwinCAT Quick Start" and "Advanced HMI - Building a Free HMI" videos prior to this.

POST THREE:

How can I change this? Are there controls (in the advancedHMI project) that allow to do what I want? (push a value (float) from my VB program into the PLC)

Thank you for any help!

@jadexvdp There are two ways. One is to use the Keypad cotrol, the other is within code: Try  TwinCATComm1.WriteData("PRG.Va­ribleName", 1234) Catch ex As Exception MsgBox(ex.Message) End Try

Very cool demonstration with nice graphics, thanks for posting.

Another solution is to use a PLC that supports Codesys web visualizations, that way you can display it on any browser on the network. I have some tutorials on my channel showing how this can be done.

@arj3090 Thank you for your reply, it was indeed very helpful, exactly what I was looking for! : )

POST TWO:

Now, I want to try and have my VB program determine a float and set it inside the PLC. So not monitor a float value present in the PLC, but push a float value inside the PLC from my VB program.

I tried this by having my VB program set the DigitalPanelMeter.Value to a certainvalue, but the value in the PLC isn't changed. Instead it gets immediately overwritten again with the value inside the PLC...

POST ONE:

A question about the TwinCat-VisualStudio link:

With some controls, f.e. the MomenteryButton, I can swith a BOOL variable in a PLC program on and off.

With other controls, f.e. the DigitalPanelMeter, I can monitor values (f.e. a float) in the PLC (They get displayed on the GUI element, once the PLCaddress is set correctly).
