Hello,
Please check this post.
Values extracted from JSON are tags of Communicator. They bound to channels and displayed in a common way.

There are Modbus scanner apps. They can read available integer registers, but do not provide info what a register means. And probably they are not efficient with floating point numbers.

[Mikhail]

Hi,
Modbus register addresses and data types should be specified in the device documentation, or declared by a PLC developer. The Modbus protocol does not support providing the list of registers from a device.

Hi,
Access to the files is denied. Could you share the files?

[Mikhail]

Hello,
Archive options can be found in Server – Archives.
May be ask a more specific question.

[Mikhail]

Device template is not the cause of that error. You should check the device settings.

[Mikhail]

Hi,
May be the controller’s IP address is not specified in the device settings. Please follow this article.

The question about measuring time should be in a separate topic. Thank you.

[Mikhail]

Inside the server logic there is a matrix created based on object inheritance and role inheritance. I hope, in the future we will somehow display that matrix for understanding.

[Mikhail]

Yes, the idea of inheritance is joining roles.

If a user has access rights to a parent object, he have access to child objects. No need to explicitly specify rights on the child objects. It saves a time needed for configuration.

Hello,
Please write a question to a proper topic or create a new one.

Hi,
To update a register on the Modbus device, you need to send a command to the device. To do that, you need Automatic Control Module. The module can trigger on the counter channel change and send a corresponding command.

The OPC client driver of Rapid SCADA uses the official .NET libraries provided by OPC Foundation to deal with OPC. I’m not sure that we can easily change them.
