Hello Darren,
Try checking the installation of WCF 4 or 4.5. It is a part of .NET Framework required for the schemes. Depending on the version of Windows it can be among Windows features.
Is there ScadaScheme.log in C:\SCADA\ScadaWeb\log ? If it exists, what does it contain?In the future versions we are going to use pure HTML5+JavaScript and such problems will disappear.
Probably your vague memorials is about other protocol than Modbus )
Modbus has special error codes for such cases or device does not respond anything.
Good luck in experiments! Your questions help others to solve their issues.The device responses the same bytes as were requested.
According to MODBUS APPLICATION PROTOCOL SPECIFICATION and MODBUS MESSAGING ON TCP/IP IMPLEMENTATION GUIDE the content of the response is definitely wrong.You can get proper communication log for comparison by using Modbus emulator mod_RSsim
Try the following:
1. Create a simple console application that play a sound. You can use Microsoft Visual Studio 2013 Community Edition.
2. In the formula call
System.Diagnostics.Process.Start(“C:\\MyPath\\PlaySound.exe”);
3. Be careful using such formulas. Do not use them for calculated channels.Please, write here about the result.
Hello,
Formulas are calculated on a server machine by SCADA-Server service.
Most likely Windows doesn’t allow services to access a sound card.
What device should play a sound in your case?Sorry, I don’t get into the way of using GUI on Linux.
Just install Midnight Commander
sudo apt-get install mc
and run the necessary scripts.
Also it is a good idea to use Putty to remote connection to your device.I hope that SCADA-Web for RPi will be ready within a few days.
Could you tell more about the system that you are going to implement? The understanding of the aim helps me to suggest the best solution.
Porting of SCADA-Web is under construction. You can wait for it or fork the project on GitHub and make the necessary changes.
The one of known issues – Raspi doesn’t contain real time clock. That’s why after reboot a system, SCADA may write data with incorrect timestamp. This issue can be solved by writing special script that starts SCADA after a clock sync.
Dear Tom,
I think Rapid SCADA perfectly fits your purposes. Of course you can use it.
Rapid SCADA has low hardware requirements, full features and stable.
Talking about possible problems, we have no enough statistics about working on Raspberry Pi because the appropriate version of the software was recently created.The best way is to start using Rapid SCADA on Raspberry and interact with me in this forum to discuss and solve issues.
Thanks!
