Magelis XBTGT HMI with PLC M241

[Olofsson]

Hi,

I have a project where I have new PLC M241 and an old Magelis XBTGT HMI (XBTGT 5330). The plan is to connect these two with modbusTCP but I have some difficulties to get this to work. I think mostly because the HMI model is deprecated. But for now, I need to work with what I have.

In Vijeo I have selected the modbusTCP driver and I have set my variables as external.

 

In Machine Expert I have the Generic Modbus TCP slave.

And as you can see, I have an alarm. Which is not so helpful 😕

The Industrial Ethernet Manager is happy though

Does anyone have an idea on where I have messed up? Or where I should continue with my trouble shooting?

Thanks!

Hi

You don't need to set in a Modbus Slave in the M241. The PLC should act as a Modbus Server and you have to activate the protocol under the Ethernet interface in Machine Expert

That takes care of my alarm alright 🙂

But then what? How do I find the addresses to the variables in the HMI?

If you are using the Modbus Driver you define addresses in VJD, ie 40001 is %MW0 in PLC depending on your settings on the Driver

Hi @Olofsson ,

Please take a look into this video to connect teh PLC with an HMI in Vijeo Designer using the Machine Expert protocol:

ANother solution using the MOdbusTcp driver in HMI take a look into the next application:

More information about the address in the PLC:

Good luck!

So simple...

I got it to work with a slave but then I had to declare the inputs and outputs. This is far better!

Big thanks !
