Post by mmoncada on Dinamically loading recipes ^{CODESYS Forge talk (Post)}
I'm having trouble with the initial loading of recipes. I can create them and load one or the other, but when the program restarts the recipes are not listed. I'm calling: RecipeManCommands.ReloadRecipes and then RecipeManCommands.GetRecipeCount which returns 0 recipes. None of the methods returns error and if i call them again after RecipeManCommands.CreateRecipe RecipeManCommands.ReadAndSaveRecipe getRecipeCount returns the number of recipes created. When i restart the system, once again they are not listed even though the recipe files are there. Any ideas? Martin Btw, Codesys 3.5 SP 16 Path 9

Post by ducng on SMC_FB_WASNT_CALLED_DURING_MOTION when enable MC_MoveRelative ^{CODESYS Forge talk (Post)}
Hello, I am using an Inovance PLC to control a servo via EtherCAT. When I enable MC_POWER, the drive switches to Run mode successfully. After that I call MC_MoveRelative, but I get the error SMC_FB_WASNT_CALLED_DURING_MOTION. The servo vibrates but the motor shaft does not move. I am new to EtherCAT/servo motion control, so I would appreciate any guidance or suggestions for troubleshooting this issue. Thank you in advance for your help.

Post by imdatatas on Unrecoverable SoftMotion state after switch to PreOp ^{CODESYS Forge talk (Post)}
Dear @alimans, Additionally, As far as I know since starting from Softmotion V4.18.0.0 automatic restart behaviour for an axis has been changed for this issue. See below explanation from release notes. "With CODESYS SoftMotion 4.18.0.0, the behavior of SoftMotion axes after a loss of communication to the servo drive has changed. Now, an automatic reinitialization is performed as soon as the communication is established again. Before, an explicit call to SMC3_ReinitDrive had to be performed. An example for a loss of communication is that the cable to one of the drives is unplugged." Regards, imdatatas

Hi, you can call the decoder function block in a loop and/or decrease the task cycle interval of Task_PATH.

Post by hermsen on Raspberry Pi 4.12.0.0 SL also stops after 15s ^{CODESYS Forge talk (Post)}
After installing this new 4.12.0.0 SL version on my RPi5 8GB and the latest bootloader, the runtime disappeared after 15secs. The bootloader my pi uses is from 2024-06-11. I was able to resolve this issue using this post: https://forge.codesys.com/forge/talk/Runtime/thread/be25c0ff66/ The workaround works for me.

Post by markushunter on Different behavior between the "Start" button in the IDE and the Cmp function "AppStartApplication()" ^{CODESYS Forge talk (Post)}
One workaround is to create a second application which is started after the rested of the main application. The second application starts the main application after time x and is rest after done start of the main application. No problems during the fieldbus re-start by this workaround.
