Post by svn123 on In Simulation Mode, logic is not executing ^{CODESYS Forge talk (Post)}
Please check the attached snapshot. I am converting an int to real and storing in rVlv01_SV and then scaling the value using LIN_TRAFO. In the bottom Status Bar of Codesys, both RUN and SIMULATION are visible. When I enter value 100 as input to INT_TO_REAL instruction and press Ctrl-F7, the value can be seen at the input but the logic seems not to work. I searched for help but could not find anything relevant. What could be the reason. Codesys ver3.5.11 svn

Post by atone on CAA File Handling: "Read only" error ^{CODESYS Forge talk (Post)}
In case of error while opening the file to read you assume that the file doesn't exist and try to create one. But it could be that the SD card is not ready yet or simply not there. I would try to check first if the SD card is there and accessible. Otherwise with FILE.Create you could end up creating a new directory that is not mapped to the SD card. This would explain the errors even after a reboot, though it doesn't explain the READ_ONLY_CAA error I guess? I would use FILE.DirOpen and FILE.DirList to check if the SD card is there and ready.

Post by artem1223 on Synaxis of library declarations in the ST ^{CODESYS Forge talk (Post)}
Codesys 3.5 17.30, plc - crevis GN-9373. I need to use RTC of pls for write in registers (need to check difference of writen 100 and 200 registers). For this i try to use SysTimeRtc (SysTimeRtc.SysTimeRtcGet) but its not working. After it i tryed to use SysTimeGetMs and something like this but still not working. Library? Mb but check project, SysTime with SysTimeRtc already, all what i know - already is here. Its my first try to learn ST (early used fbd and ladder, yeah), pls help with it. Mb problem with a syntaxis, but im not sure.

Post by andrax on Save Recipe on Paspberry ^{CODESYS Forge talk (Post)}
Unfortunately not. The folder does not work. There are neither error messages nor any other indication that this may be due to missing rights. I have searched the entire forum and also tested the Codesys example. The simple recipe management generally does not work! The Raspi crashes with the extended recipe management from the example. I have now found another sample that works. https://forge.codesys.com/forge/talk/Engineering/thread/61c6a04b79/ Many thanks to mcodem. After some trial and error I have found out: xcreate must be called at least once at runtime. After that xload_write and xread_save work All other functions do not work. It is also possible to save to the /home/Documents folder. So it is not due to the rights. It would be nice if Codesys would check where the problem really lies.

@fscardovi You might check the location of your CODESYS.exe.
