I cannot even get the test project with KpModbus_Adam6015.xml to run. I get “error” instead of normal and communication error.

If you provide screenshots, I will try to help you.

Does my other program polling the PAC3200, powerconfig, have to be offline to communicate?

If you use RS-485, the only one application can poll.
If you use TCP, it depends on a particular device. Many devices support only 1 connection.

After you do the above, next step is integrating OPC server with SCADA.

OPC server is a software developed by a manufacturer of controller.
First, you should download, install it and get data from a device.
If you need support in this process, you should ask developers of OPC server for help.

Hi,

You should try SMA OPC SERVER.

Other option is creating a native driver for Rapid SCADA which interacts with Sunny Webbox directly.

Hi,
The start question was about another thing.
RPC, JSON and Modbus are completely different.
You should start a new topic and provide the datasheet of your device.

In the properties of communication channel untick the checkbox “Stay connected”.
Increase the timeout and delay parameters of the device.

Hi Vishnu,
Please post the same log as a text (not image), so I can check it using a tool.
You can find the file in C:\SCADA\ScadaComm\Log

Hi,
If Windows itself works fast enough, it will be OK for Rapid SCADA.

Hi,

To be honest, I did this the first time in my life in the simulator.
Likely, addresses are displayed in the left column. The same addresses are specified in the Modbus template in the project.

Enter 1 into Address and
enter 192.168.1.103 into Call number.

Hi,

The formula is incorrect.
It’s better to fix error in KpMqtt to make it stable. Could you write here the error which is written in communication line log when connection lost?

Since then some websites that I visit every day or at least every 2 weeks have buttons that run scripts but when I click on them now, nothing happens.

Rapid SCADA is not related to any other websites.
