Hello,

I am looking for a way to change an image live on the file system and have it updated on the target/web visu.
It seems that once the runtime has loaded, it will always display a cached version of the image on the targetvisu.
I have tried unregistering/registering the file, but it does not seems to do anything.

BmpPoolUnRegister(IMAGE_POOL_ID);
BmpPoolRegister(szFile := IMAGE_FILE_LOCATION, szId := IMAGE_POOL_ID);

I have also tried registering a new file under a new ID without any luck.
Changing the page does not help either.

Is there a way to do this without restarting the runtime in 3.5.4.x?

Thanks!

Hi,

this is only possible with a setting:

in webvisu.cfg.json in /visu "NumCachedImages": 0

Code:

{
"UpdateRate": 200,
"PlcAddress": "0000.9ED4.C1D5",
"UseLocalHost": true,
"Application": "Application",
"StartVisu": "SendTweetVisu",
"NumCachedImages": 0,
"BestFit": true,
"LogLevel": "INFO",
"CommBufferSize": 50000,
"HasKeyboard": false
}

Then you need to take care that CODESYS doen not overwrite webvisu.cfg.json on every download - make it readonly or change the name in CODESYS to webvisu_my in CODESYS.
