Relationship between the number of points of parameters managed by the OPCUA server and the communication cycle.

Thank you for answering my question.

Is there a correlation chart between performance and registered parameters?
If it exists, I would like it.

How can I set up polling?

Thank you very much.

We don't have any correlation chart available. 

In some cases it might be a good way to get the values by c# code - by this you can controll the update rates in a very detailed way - how to access it via code can be found on this page here:

I tried with the polling checked, but it got worse. (It froze and stopped working.)

[Questions]

1. When I checked the script I described in reference to the sample,
   I found that the "ReadNode function" is called with "FixedUpdate" when polling is enabled.
   Is this correct?
   Or is it intended to be used in a way that the user can play with whether it is called at "FixedUpdate" or at some other cycle?
2. If polling is not enabled, how and at what period do you read the OPC server?
   

[Prediction of what is happening]
When polling was disabled, we can communicate piecemeal, although it was not clear which function was being called in which cycle.
When polling was enabled, the "ReadNode function" was set to be called in a fast "FixedUpdate" cycle, which increased the number of calls and the load on Unity itself, resulting in a super drop in FPS.

Hi, you are right - polling is currently in FixedUpdate. We should implement in the next release a cycle time when the Read is done so that you can slow it down. Currently only way for slowing the polling down is to call the ReeadNode function manually in a custom method. Sorry for the misunderstanding.

Thank you very much.

We should implement in the next release a cycle time when the Read is done so that you can slow it down.

1. When do you plan to release it?
2. Are you planning to implement it for sure?

Could you also answer the following questions?

2. If polling is not enabled, how and at what period do you read the OPC server?

1.)  we can do a beta for this until end of next week

2.) yes

Weather you read in code or you subscribe to the variables. If you subscribe to the variables it depends on the subscription parameters. There is a (requested) subscription publishing interval. It also dependes on the server settings how ofthen the subscriptions are published.

Is it possible to get a beta version?

Yes you will get a beta asap.

We released a new version including what you requestet. It is version 2021.17. You can find it on the Unity Asset Store and on our download pages - depending where you purchased it.
