Any plans to develop an OPCUA version?

For Arduino UNO maybe could be a bit heavy but maybe for YÚN could be possible. Any plan to use it in a real project to test it?

Hi! I think a OPCUA Version running on either the Yùn or perhaps the zero would be very interesting to test out. I can think of multiple uses for this at my workplace, ranging from valve automation to pressure control just to mention a few things.

Thank you Martin for the information and suggestions

At this moment I have no plans to integrate OPCUA because not enough time but maybe soon ;)

Sorry to reopen this! But if you want i can help you making an UA version of your great job! I'm working on a simulation platform based on a cortex m0+ (feather m0 wifi) and i want to integrate OPCUA architecture! I saw this project (https://github.com/Pro/open62541-arduino) but i can't build it with arduino ide!

Hello

some Arduinos does not have enough power to server OPC UA....I am trying to do it with a Yun and OPC library from https://github.com/FreeOpcUa/python-opcua but need more space than the memory of the device....is a progress work

maybe could start from there?

Hello Arduino Yun have both linux and arduino core, but my platform is based only on arduino core, meanwhile i wrote to the open62541-arduino repo to ask some help :)

You simply need to find an AT Mega based MCU that supports the hardware foot print necessary for the OPCUA stack and port accordingly.

I agree that this should be developed in OPC UA. At this moment this is working on COM/DCOM what is a huge drawback. There would be much more capabilities using Ethernet, you could use with phone etc. Then this project could become very useful.

I want to create an Arduino OPC UA server. Will it be possible to create an Arduino opc Ua server? Does Arduino equipped with OPC UA protocol?

[nzfarmer1]

Not enough SRAM. You could start with an STM32 and it would be a worthy project. Run it on a linux flavoured RTOS.

Thank you for your suggestion. Could you provide me any source that will help me? I want to communicate via LAN cable and want to send sensor analog data to the the OPC UA client.

You could start with something like this. But I think you may be underestimating the effort a bit.

Hi all, sorry for my delay on this topic, i'm stuck with porting Open62541 to my Feather M0 + WIZ5500 ethernet featherwing. I am not a cmake and code compilation expert so i have some trouble with this library! If anyone has made progress in the meantime let us know!
