When I disconnect from the Modbus device, I get a warning in the schema editor, for example to change the colour of the LED to red or to print a warning that the connection has been lost! When I write a script, I cannot log in to the interface, I get an error message like the application is not ready, if the connection is broken or I cannot access the device, I need to specify this in the schema editor if status:error. Can you help me thank you very much.
If you wrote a script with an error, the Server will not start, you can see the cause of the error in the Server log, which is likely to be in CalcEngine.cs
Is there any way to get the warning of the device that I cannot access without writing a script in the schema editor? If I can only do it with script, can you share a script example?
Each device has a service channel with the Status tag code-0=Normal, 1=Error
Just add a channel to the created driver and specify the Status tag code for it, select the Normal-Error format to display in text or leave D to display 0 or 1 as desired.
As you stated, I added a channel to my driver, I edited it as Tag Number 1 Tag Code Error, I entered the channel I added as input to the led object in the scheme editor and made conditions, but the led did not change colour, can you explain a little more descriptively with visuals if possible?
I want to create a channel in this way and change the led colour according to its status, but I can’t do it.

I understand, I edited it as in the image, but where should I enter the status of normal or error, that is, the area specified as (reserved name for driver), that is, how will I detect the status through this channel? How should I proceed now, as in the image Thanks in advance.
Now I understand and solved it, thanks for the help, I’m sorry if I had difficulty understanding, is there a resource you can recommend to learn rapidscada?
For example, as the next step, when I cannot access the device, I want to print the device is not accessed ?
You can probably create a calculated channel with the right length to accommodate your message. Specify it as Format = String.
Specify that these channels are not saved in the database, so as not to waste space. And write a script that will write a line with your message into this channel when the signal = 1 is in the form of an ascii or unicode string.You can also add new enumeration text in auxiliary tables – formats. For example, for each device that you will have. It will most likely be
it seems there are educational videos on youtube. There is also a Documentation section on the website.
is there a resource you can recommend to learn rapidscada?
