Note that executing external scripts is not secure. They can hang, or can be modified by an intruder. It’s better to interact with other services via API or industrial protocols.
Hello,
The general algorithm is as follows:
1. Send a command via the web interface.
2. In a channel, use an output formula that executes a script.
3. As shown above, the channel’s output formula should run a command likeProcess.Start(@"C:\SCADA\1.bat");Ask for more details if needed.
It means exception throw in OpcNetApi.dll. Maybe OpcNetApi.dll not implement the requirement interface(IOPCServerList2, I found project B implement and it doesn’t use OpcNetApi.dll)?
Sometimes it’s possible. If an OPC server implements not all required interfaces, some OPC clients work with it, others don’t work.
Where do I have to enter the program call so that it can be called by the UI? In views? How?
If you need to execute some external app from the web interface, there should be another approach. Please create a new topic to discuss it.
For example, if some channel value > 0, the module can send commands to switch a led. Use a channel data trigger for this purpose.
Hello,
The mentioned article provides basic information about using formulas. You can create your own scripts and formulas.
Check the Scripts table of the HelloWorld project for the examples.Hello,
I am also interested in the possibility of creating a pure CSV file without an XML header.
Could you provide an example of the existing file you get and a file you need?
Is it possible, like the other plugins, to integrate the function into the frontend
In the modern Administrator app, there is ExtExternalTools extension. Using this extension, you can add custom command to run command line utilities from the UI.
Hello,
According to the manual,
“An instance is a set of Rapid SCADA applications running the same project and installed on the same computer.”Hello,
Possible cause is that the communication channel is not configured. Please provide screenshots of the communication line main options.So, you can send a command from Rapid SCADA to the device. Commands can be send using the Administrator application and the web interface.
