System:
Node-red Version: @1.0.4
Device: Simatic IOT2040
SO Image: 2.6.0

There's any way to install/run this package on my device?

Hi, this error is not related to this node, but instead to [email protected] that is not available. Please try a clean install, and let us know if the problem persists

[elyancorrea]

Thankou @gfcittolin,

I followed this step on: https://support.industry.siemens.com/tf/ww/en/posts/problem-adding-nodes-to-node-red-with-v2-6-0-image/229076/?page=0&pageSize=10
After this, I can install OPC-DA module normally.

However, when I try to "Test and get items" still getting a message:
"No response from Node-RED runtime"
You know if is a problem from my install? There is a way to test opc-da module?

Greetings
Could you post your Node-RED log?
Thx

I did a fresh install of my image on Siemens IOT2040 and installed node-red-contrib-opc-da, no problems until now.

When I attempt to connect do OPC server, got this error:

4/7/2020, 6:07:38 PM
msg : string[45]
"Disconnected from the server - Unknown error!"

@gfcittolin @gfcittolin
I did a fresh install of node-red + node-red-contrib-opc-da on raspberry pi running raspian and got same error. I realized that my computer runninc OPC Server is not in a domain, just in the "workgroup", does it affect behavior of node module? What is the requirements from OPC Server computer to work with this node module? OPC Server PC need to belongs a domain? Thanks for the reply.

[gfcittolin]

No, you should be able to connect to it even if it's not part of a domain. What is the server type / OS you're trying to connect to? Speaking of Windows, you'll probably have to setup your system so that it allows external OPC access to it

[elyancorrea]

@gfcittolin
OPC Server is running on my laptop: Windows 10 Pro (no domain) Version 1909 Build 18363.752 - Static IP - MatrikonOPC Server for Simulation;
If I don't have domain, workgroup is compatible? I can't leave blank.
Where I can find a log for connection issues?
You recommend any setup to allow external access?

Currently we have a few issues on W7 and W10 environments. Fixing those is in our roadmap but for now we really don't have an alternative since we are still trying to figure out what is happening.
Thank your for your feedback.

Thank you for your reply.
Which setup are you running your server on now? so I will set up a similar server here. After this I can help you to improve documentation.
Congratulations for your work.

[steuck13]

Sure, currently we got testing machines running NT4.0 and XP SP3.

Your help is more than welcome

I've done a WINXP laptop run Iconic Simulator as a OPC Server, now I got this message when I try to connect:

I've double checked my ip, user and password, I don't have domain, so I typed "WORKGROUP". There's any idea? I should change any administrative settings on laptop to give access? User is admin.

Ty for your help.
*P.S: Timeout is 1000ms cause i was testing, however behave is same with greater values.

Did you configured your system's DCOM to work with authenticated users? Here you can see how to do a setup for 'everyone' but the procedure is the same for authenticated users.

Hello @steuck13
I was unaware of this setup, I will do it later and inform the result.

Ty.
