[UNSOLVED, but ignored] Simulink model with red border and outlinks
112 views (last 30 days)
I built a Simulink model and from a certain point, where I don't exactly remember my commitment to that, one subsystem is framed by a red line and the background turned yellow. Please see screenshot attached. Because of data policy I had to pixelate some parts...
There is literally nothing displayed that reveals anything of the cause for that. Taking a look inside of that subsystem, there is everything as usual with respect to the colors. As I seem to be the first one in this company having that problem, noone other knew a solution, nor I was able to find a solution using searching machines.
Despite the simulation still runs, I would be extraordinarily glad to get rid of that suspicious red box. Any help is appreciated!
Best regards, Patrik

I've seen blocks get "stuck" like this several times after errors. If you right-click on the block and select Format, you'll likely see that the foreground and background colors are set. I just change them back to black and white (or whatever I'm using).

There are many sources of error/ warning in your model, am just listing something
1. the error may be due to input signal/data length or data type or handling the data inside the subsytem may be the the problem
2.It may be of data dependency error
3. Enabling some warnings/errors setting in configuration parameter settings

You should not ignore this error (bug?). In my experience, if your block is Red, then you can have problems if you interact with your block programmatically, e.g., you are not able anymore to set the "logs" of your signals 'on' or 'off' programmatically. A quick workaround for this problem is the following: 1) ensure that all your I/O datatypes are correctly set (into Model Data Editor) 2), select everything from your block and COPY. Now go outside your block (i.e., one level up), and PASTE everything. Now regroup into a new block using the just pasted (yet selected) elements (under windows, CTRL+G). This will re-create a new block, hopefully black instead of red. You can now delete your old red block. I have solved my problems with this workaround.
