Hi,
If you simply need to change command value, you can set a formula of the output channel to 1, for example.

Do you have an input channel that changes according to a command?

Hello,
ModRapidGate.xml and ModRapidGate_Reg.xml are created automatically in the proper location of the project when you configure the module using the Administrator application.

I guess, OPC server should have an option that allows to restrict publishing speed. Or may be, it’s a client subscription includes such parameter. For example, Rapid SCADA OPC UA client subscription have the Publishing interval option.

If your project requires work with a large amount of incoming data, we can take part in it to improve existing Rapid SCADA modules.
Alternatively, if you are a software developer, you can join the development and submit a solution.

Just for info: PostgreSQL archives (ModArcPostgreSql.dll) appends all data points in the queue. And it’s easy to monitor the queue size and data insert rate.

Talking about Influx DB client, we can implement our own data queue in Rapid SCADA to gain more control. But that would be stupid, since the Influx DB client claims to provide a built-in queue as a feature.

Hi,

You have done interesting tests.

1. OPC UA. If you sent data to the OPC UA Server data source (implemented y DrvDsOpcUaServer.dll) fast and for a long time, are there some RAM issues or hangs?
Currently, I have no info how such situation should be processed by the used libraries https://github.com/OPCFoundation/UA-.NETStandard
Would you ask the OPC developers on GitHub? If you ask please share a link to the issue.

2. Influx DB. There is no limits. If data points are sent too fast, the internal queue of the client should eat a lot of RAM. Could you post a screenshot of the archive settings and data samples?
Check the issue I created a few months ago https://github.com/influxdata/influxdb-client-csharp/issues/478

There are 2 different issues.
1. Lock of ScadaComm.txt file. Try deleting the existing file, so it will be automatically recreated.

2. Browser error. Could you switch to the Network tab of the tools to check which request causes the error?

Note that in the screenshot of the device data, the tag is not bound to the channel. It is incorrect. You should not change channel data type manually.

Hello,
Glad the problem got resolved.

Hi,

SVGs containing JS are not tested.
You could open the browser tools pressing F12 to check the errors.

[Mikhail]

Hello,
Please provide the screenshots.

I mean get channel value and status in your database. After that play with SQL functions to set channel value to NULL if status = 0.

[Mikhail]

Hi,

It changed in Rapid SCADA 6, see the example https://ibb.co/zXj9HCN

Hello,
What username is written in the Communicator log?
If the port exists, but cannot be open, you would get another error message.
Could you copy here a part of communication line log?

[Mikhail]

SQL functions should be used. First of all, get the correct raw data. Then try using SQL functions to add some processing.
