Post by rkohser on Python Script for Finding "Last saved with" Value ^{CODESYS Forge talk (Post)}
Hi jkilburn, I have the exact same issue and thought I would search a solution on this forum. I see you did not get any answer, did you find a solution on how to extract the last saved version of codesys from the project file ? Roland

Post by dhumphries on Using Codesys example problems ^{CODESYS Forge talk (Post)}
You have to install any libraries needed by the sample program. Click the button with ... next to one of the errors (see attached image,) then choose download missing libraries. Codesys should automatically locate and install the missing libraries, it's not flawless though, I've had some issues getting libraries to install. The best advice I can give if it doesn't work is re-install Codesys.

I am looking for some help with using Gifs in the WebVisu of codesys 3.5.18.40 as the model we tried with ladder logic does not animate the Gif and leaves as the first image of the Gif. Is there a way for ST or LL for it to be animated?

Post by durstloescher on Library Documentation DocScripting ^{CODESYS Forge talk (Post)}
Hi, I am currently creating a documentation for our library with DocScripting. In the process, I noticed that Visu images are created before the merge and transform, i.e. "screenshots" of the different Visus. Unfortunately, these are not used in the later process (Merge/Transform). Is there a way to set it up so that they are found in the html file?

Finally this solved my issue: https://forge.codesys.com/forge/talk/Engineering/thread/3da9ded84e/, and the official documentation https://faq.codesys.com/display/CDSFAQ/SysFile%2C+Persistence+Manager%2C+Datalog+Manager . Add the media folder to the PlaceholderFilePath. Like this: PlaceholderFilePath.2=/media/pi, $usb$ PlaceholderFilePath.2.View=1 PlaceholderFilePath.2.Volatile=1

My experience is that opening pdf file is very dependent on which browser is used. I have tried a couple of them and only Mozilla Firefox has opened file correctly in same screen. All other browsers face some issues. Therefor I had to flip my pdf to txt which has not been nice solution.

Hi @eschwellinger Just wondering if there is any update when the Expression or part of it has no effect will be fixed? Also have the ability to open an FB when online and offline. It would also be great to be able to view the ST code block when online.

Post by felipemsgarcia on Generic EtherCAT slave ^{CODESYS Forge talk (Post)}
Hello Edwin, Thank you foryour answer but, I believe I was not very clear in my question, sorry. What I wanted to know is if there is a generic EtherCAT slave object already in CODESYS that I can use for anything, remote IO, Drives, VFD's and so on, as long as I match PDO's. Is there such an object? Thank you again!

Im using SysCom ver. 3.5.17.0 and seem to have the same issue on a Raspberry Pi. It's not waiting for the requested number of bytes, no matter if "ulTimeout := SYS_INFINITE" or any other value. The only solution I have found is to stall the program to allow the serial port to recieve the data.

Post by timvh on Array to String ^{CODESYS Forge talk (Post)}
The new (UTF8) string library is faster and can handle large strings. https://content.helpme-codesys.com/en/CODESYS%20String%20Libraries/_strlib_start_page.html PS, in CODESYS, the maximum string length is not 255 characters. The String functions of the standard library are limited to strings of 255 characters. But you can use other (memory) functions to handle strings larger than 255 characters.
