Currently I use ModBus, but the goal is to support any kind of PLC4X driver …
My hope was that every PlcValue in PLC4X has a timestamp and a status … and if
the protocol does not support it, then the timestamp/status should be
“undefined” ...

So far the only protocol I worked on, that supports this "quality of data"
feature, was the delta-v protocol. For all otbers we would have to provide the
constant max value.
Unfortunately their was the only driver I wasn't able to finish. As I have no
hardware available.
So this
This is not a simple questing and depends on the protocol and device you are
using. What are you using?

Hi,
How can I get the source time of a PlcValue?
a) from a subscription PlcSubscriptionEvent
b) from a read request PlcReadResponse
Best regards,

Thank you Ben, for me it is not super important. For OPC UA I use Eclipse Milo
“native” (without PLC4X)… I just wanted to test subscriptions with PLC4X.
Is there a documentation of this sampling subscription api? I assume I can use
that kind of subscription also with drivers which does not
Hi Andreas,
It looks like there's a bit of a mismatch between the PLC4X change of state
api and the Milo subscription api. When using the change of state
subscription that is used in the example a default duration gets used of 1
second it also doesn't look like it reports by exception which I
Thx, it works now.
BUT: I only get values every one second…

Hi Andreas,
That looks like an issue specific to your setup. It seems it's not finding
some of the other modules that the opcua driver and the example rely on.
Can you build the entire project 'mvn clean && mvn install'?
If you could send through some more info, maven logs, etc.. it would be
Hi Ben,
with this Branch I get a build error - just opened it in Intellij and tried to
run the subscribe example...

Hi Andreas,
I also saw the same issue running the example. I have just pushed a branch
to fix this bug/opcua_subscription. If you can try it out that would be
great.
Kind Regards
