Hi,

Generally I would recommend using the grapchical tools to learn OPC UA to understand the basic concepts, i.e. https://www.prosysopc.com/products/opc-ua-browser/, https://www.prosysopc.com/products/opc-ua-simulation-server/, https://www.unified-automation.com/products/development-tools/uaexpert.html, https://www.unified-automation.com/downloads/opc-ua-servers.html .

With the SampleConsoleClient, you will need to first navigate to the node for which you want to write by using the option ‘3’ to Browse to the desired node, and only after then use the ‘5’ option for writing, i.e. the options are relative to the “Current Node” displayed above the menu. Additionally for writing to the Value Attribute, you will need to use the ’13’ option (i.e. the 13 – Value; after ‘5’) to actually to try to Write to it (since any Attribute could in theory be written in OPC UA).

Also the writing capability of that sample is rather limited, it will only work on basic types.

As far as I’m aware there isn’t exactly a video tutorial like you would like (could be maybe a good idea for the future). Usually people read the user manuals of the applications and that is mostly enough. Or well usually they just install them, run them and usually figure out things quickly from what is shown (or at least that is one of the design goals we have, but probably are not yet there). However our applications have a user manual pdf that can be opened from the Help menu when it is running.

Our partner’s Unified Automation’s UaExpert might have a bit better doc if you are just starting out: https://documentation.unified-automation.com/uaexpert/1.5.1/html/index.html

There are some videos on the internet about OPC UA, but I’m not sure they are on the level of detail you would like:

– What is OPC? UA in a Minute,
РGetting Started with OPC UA, Pyry Gr̦nholm, Prosys OPC, (this is a more general overview)
– Getting Started with OPC UA – End Users Products, 2018 by Jouni Aro,
– The Tech-Intro videos by Uwe Steinkrauss, you should see them from here: https://www.youtube.com/user/TheOPCFoundation/featured
– You can try to Google more

P.S.

To clarify, in general the SDK support is limited to solving technical issues, i.e. bugs. Java knowledge is assumed. Assumed is also some OPC UA knowledge, even though we usually answer them anyway as some parts are hard. However the point of the SDK is that you can develop applications relatively easy, but it still does require some knowledge.

We do organize workshops from time-to-time (e.g. next is https://www.prosysopc.com/events/opc-ua-workshop-2020-spring-finland/) and offer services (https://www.prosysopc.com/services/).

P.S.2.

Personally I would recommend reading the raw specification at some point, https://opcfoundation.org/developer-tools/specifications-unified-architecture (does require making an account, but it is free). Stating from part 1 and then 3,4, possibly 5.
