Question: Using the TCK with an sparkplug enabled device

[omarhogni]

What do you want to know?

It seems that a device id is required for some of the tests to run properly. Is there something I am missing and this functionality already exists?

replacing the device id with a space character enables some of the tests to be run but not all of them.

Is this related to a Sparkplug Listing request? If so, link the issue from https://github.com/eclipse-sparkplug/sparkplug.listings here.

Hello and thanks for your inquiry.

If you are using the TCK to validate a Sparkplug Edge Node, the device ID is required. The device should have a field that defines the device ID. It's possible the value is a constant but it should be advertised.

I believe he is asking weather the TCK will support Sparkplug Enabled device

as opposed to Edge Node

since Sparkplug Enabled device doesn't require device ID

[bryce-nakatani]

Sorry. I misspoke. Your device may not represent a device, just node level tags. I'll see if the TCK developer has any ideas.

I hadn't considered this variant when writing the TCK - no-one pointed it out to me either.

Does this mean that in this situation, a Sparkplug Node carries out all the operations that would otherwise be implemented by a Device?

So NDATA instead of DDATA, NCMD instead of NDATA?

That will need some TCK updates which I'll have to think about and get back to you.

@bryce-nakatani I assume we can't have a Device without a Node as well?

[bryce-nakatani]

Devices are optional to a node implementation.

I sculpted my implementation so that multiple devices could exist under the node. Thus all my implementations contain devices (even if there is only a single device possible). Tahu's Compatible Edge Node implementation also contains a device.

I have been overbiased with a node/device implementation.

I can see an implementation when a single device could be absorbed as just a node.

In the node-only case, the node publishes NDATA (similar to DDATA) and receives writes and other commands on NCMD (similar to DCMD).

@icraggs-sparkplug You're correct, devices cannot exist without a node.
