I have an iX T7A panel connected to a Mitsubishi FX3U PLC.
Additionally I need a secondary iX T7A panel on which I should be able to have read access to a number of tags on the primary iX T7A panel.
The two iX T7A panels is connected on ethernet, and only the primary panel is connected to the PLC.

How to do that?
Shall I use the Data Exchange function?

I'm running iX Developer 2.0

Kind regards
Bill

Hi Bill,

If you make the HMI that is connected to the PLC an OPC UA server, you can then share its tags with another HMI that will act as a client. You do not need to use "Data Exchange" as you will access the tags in the OPC Server HMI directly.

Make one HMI the OPC UA Server (the one connected to the PLC):

Assign a tag to mirror the value in the PLC like you always do to access memory addresses in a PLC:

Add the OPC UA server as a controller in the other HMI:

Reference the tag in the OPC Server like you normally do:
