FreeScada status of the project.
I wonder if someone is still working on this project, I downloaded the source from the sourceforge site, but this with compilation errors.
If you have someone working on this project and would be grateful to help me, I would like to take this project to meet a need and also contribute to my community in general.
My contact email is email@example.com

I am trying to work with this FreeScada program but somehow I get stuck all the time.
The available examples are not so much helpful.
What I missing concrete a good debugger, which is able to check the right methods and variable.
The most important the methods.
For example: I do not know what kind of methods (name of the method) are available for a button function or to do a graph. Or at least where I can find those.
Does someone knows???
I think buttons, alarms and graphs are essential for a good SCADA program.
I hope more people are going to work with this program thereby it gets better and better.
Nice piece of software, simple to use and easy to learn.
I have a Modbus RTU slave connection which is polling nicely and putting the decimal values on the graphical interface.
What I would like to do is scale those Modbus values to show 0-100% instead of 16384 to 49152 as recorded from the device.
I have tried putting in a computable Simulator variable with some code to do it, however it doesn't seem to be able to reference a MODBUS variable from the simulator plugin.
Has anyone else done this before?
I am about to delve into the scripting to see if there is another way.

Hello dear friends. Im trying this software but i have some questions. I hope somebody culd help me. I designed a SCADA visualization for temperatures monitoring. But the problem i have is the computer was broken. I need to use my development in a new computer. Well i saved a baackup of the files but the problem is that apparently i can not just change the original file from 1 computer to another. Because when try to open it a warning error brings up to the screen. I dont know whats going on. Sorry for my english. Thanks
MODBUS Plugin Configuration and test
MODBUS is an application layer messaging protocol, positioned at level 7 of the OSI model, that provides client/server communication between devices connected on different types of buses or networks.
It is currently implemented using:
TCP/IP over Ethernet at a reserved system port 502 on the TCP/IP stack
Asynchronous serial transmission
MODBUS is a request/reply protocol and offers services specified by function codes. MODBUS function codes are elements of MODBUS request/reply PDUs.
Guys. I had move your posts from your personal blogs to collective Ā«HelpĀ» blog, you can see a collective blogs names at bottom right of the page. Pls select the most appropriate blog when you post new topic. For do this you should be joined to appropriate blog. Look to the picture.
Also you can subscribe on new topics in joined blogs and new comments. Go to Ā«site settingsĀ» like showed in pict.
I would like to see a BCD Data type when creating a Modbus Variable. Many of the PLC's I work with have data in BCD format. This will make it much easier to attach graphics if you don't need to do the conversion in code.
Keep up the good work. I am looking forward to seeing some of the bugs fixed. I lost a few tinkering projects when the designer crashed and would no longer load the project. Once it is running and my scripting is de-bugged it seems to be pretty stable.

I am wanting to develop an application with the Free Scada,
I'm creating simple programs, but I can not call buttons with actionsā¦
I am also wanting to create a tutorial for setting up the Free SCADA
I need help from someoneā¦
It might be good to be able to use the value 255 as slave_ID.
