FreeScada status of the project.

Hi all.

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 jean.gerhardt@gmail.com

Thank you.

Hi All!

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.

Thanks Eddy

Hi,
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.

Cheers,
RFEE

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.

Hi,
I am wanting to develop an application with the Free Scada,
I'm creating simple programs, but I can not call buttons with actions…
I am also wanting to create a tutorial for setting up the Free SCADA
I need help from someone…
Thanks

Hi Alex,

It might be good to be able to use the value 255 as slave_ID.

Hi,
This is very good Project! I started to work with this programm. As an begginer I cannot find two data formats that I need for my Modbus variables'definition:
— u64 — unsigned 64-bit (4 registers)
— s64 — signed 64-bit (4 registers)
How can I set this type of data?

Also I have another question. Can I define reading schema for reading of one device with multiple variables in text redactor or in excel and after this to import the parametrization data into the programm? Can I save parametrization and copy/paste for multiple devices?

Good luck with project!

could anybody please tell me how to set up the web server free scada to web access? thks

Alguien sabe si el free scada tiene Web Server, muchas gracias
I have an Application, and I need a web server. The free scada hava web server?

I am trying to compile for the first time.

I can not seem to get VisualControls.FS2EasyControls to compile. I am getting Error The type or namespace name 'IVisualControlDescriptor' could not be found (are you missing a using directive or an assembly reference?)

I can not seem to find the reference.

It is a very good scada software;
I hope you please gon…

i want any example.

How can we use MODBUS variables within Python Scripts?
Also, Is there any manual that describes the Python commands that can be used in FreeScada?

Hi,

I'm trying to make a simple program with freescada2 and i think i already see videos with tutorial. Can anyone help me? there is any video tutorial? if yes, where is it?

Thanks in advance.

Hello,

I would like to create an «AnalogueTextValue» the will show the sum of four (4) MODBUS variables.
I have already tried to use the Simulation Settings and create a new variable_1, but I am not very familiar with the Python Syntax to do it correctly.
Can someone help me?

Thanx,
Dimitris

Hello All!

I am trying to find out, how do I change or modify a ModBus Register.
I want to create a button and this button should change a designated register which is responsible to switch ON/OFF a relay.
I am already manage to read a register, thanks to the example on the blog.
But I do not know how to change the values.
Thanks for the help and hints in advance.

Hi, I am new here, I just want to know how to use the User Controls(FreeSCADA2 EasyControls Library), thank you very much.

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

I'm using FreeScada to visualize an RS-485 network of temperature controllers. For this I'm using the chart function and the SQLite database facilities.
1) I'm getting the data in and out allright but have some issues with the chart function: The hi/lo ranges are initially set to -1,1, but if you want to set them to 200,300 you get an error message that the lower value should be lower… If you then do -200,200 it works and also 0,300 works. Sometimes the designer mode accepts a range and the runtime will then not accept the resulting case.
2) In the SQLIte database I cannot change the 1000ms value, I change it, save it, but it still comes back 1000, even after leaving the program. (I'm getting the data in my database)
3) I had issues with the chart function running on a Dutch Windows XP; The hi/lo range came out as -1;1 iso -1,1. This could be a country setting issue, but then the problem as described in 1) still happens. You may want to check in your software whether you are installing it on a US/UK based Windows and otherwise exit in the setup fase.
4) You can't see which version one is using of freescada, you can check for updates but sometimes it says there is a new one which is not true.
Keep up the good work!

Hi,
I was able to associate status of DO on my PLC via OPC connection. I could use your help on how to write (i mean change) status to my plc. Should I write a script or can i somehow do this through OPC server? Could you give me an example of how to achieve this?
Thanxs in advance!
