Hi,

I would appreciate your opinion and advice:

My customer has 3 independent machines. Each machine has 1 PLC FX3U and 1 operator panel iXTA70 (serial communication between the panel and the PLC). Here attached you will see a picture with an overview.

Currently, the user save and load the recipe on each operator panel.

But now, these 3 machines work together.
In the futur, the customer would only handle the recipes (save / load or delete) from 1 operator panel.
So 1 operator panel will receive or send data to the 2 others.
(During the operation save or load for example)

What is the best and cheapest solution to realize this need?
(For example: Ethernet Modbus TCP/IP or OPC UA ???)

Thank you
Philippe

Hi filou,

I think the easiest way would be for you to make the HMI that the operator is going to save/load recipes on an OPC UA server, and have the other two HMI's as UA clients.

Then when the recipe is loaded/saved on the HMI that is acting as the OPC server you can have it set the tag values in the two other units based on the recipe they loaded.
