In this case, if it’s possible, we should contact with the OPC server developers and works with the to fix the issue. I can assist you in email conversation. We did the same thing to fix another OPC server for BACnet (I forgot its name).
Hi,
Duplicated hereDo you know that you can simulate sending data by the Generator function of the Server app? May be it helps. Also you can write simple application that sends data to Server. I can assist a bit here.
in case new data are the same as old data, there are no new data or are not written as the values for SQL Instruction
As I remember, if data don’t change, Communicator doesn’t send them to Server, so they are not passed to DB.
To fully understand your task, I have to do a research. This is not a part of free support. I can reproduce a simple example, and if it doesn’t work as expected, fix it. Also I can explain how Rapid SCADA works.
Another option is connecting to your machine remotely and find out the cause of the problem. This is a commercial service.
I hope I can help you in a one form or another.Anyway, I think I understand what you are talking about. How would you like the software to work to make your task clear without tricks? Should Communicator send all data, that were read, after each communication session?
Hi,
Try this utility to test https://yadi.sk/d/d1UOUw153DcoDp Does it work?
When does E_NETWORK_ERROR occur?The OPC server also can be the cause of the problem. For example, we contacted with a developer on a one OPC server to append the proper implementation of all needed OPC methods. When he does it, connection was OK.
I think, it is possible to create a component for schemes that can show IPcam in a popup window over a scheme.
Why you don’t use hardware modules that counts off/on cycles? This would be much reliable and transparent.

Could you open the code you interested in by GitHub and copy link to a particular line of code? Of course, I will help to understand.
