Post by imdatatas on The default ramp type selection in SoftMotion V4.18.0.0 is Quadratic ^{CODESYS Forge talk (Post)}
Dear @gseidel, @tk096, I noticed that with SoftMotion V4.18.0.0, if a new axis is added to the project, the ramp type selection defaults to "Quadratic". In all previous versions, the velocity ramp type selection was "Trapezoidal". This causes some unexpected issues in projects with SoftMotion version V4.18.0.0 for newly created or newly added axes to existing projects. Is it possible to reconsider this situation in the next update and set the velocity ramp type to "Trapezoid" by default again? Best Regards, Imdat

Hello everyone, Updating and converting an existing working Codesys Softmotion axis control project to the latest Codesys IDE and Softmotion version always gives the following error message during compilation. " [ERROR] sm3_basic, 4.18.0.0 (codesys): MC_MoveAbsolute: C0138: No matching 'FB_Init' method found for instantiation of SMC_MoveAbsRelPerformerImpl " -- Previously working version: Codesys IDE SP18.50, Softmotion 4.10.0.0 -- Later updated version with the error: Codesys IDE SP21.10, Softmotion 4.18.0.0 Has anyone encountered a similar issue? How can this be resolved? Regards, Imdat

Post by bmatlove on AXIS_REF_SM3 Error Codes? ^{CODESYS Forge talk (Post)}
I'm trying to firm up alarming of axis faults. Declutter the code and figure out what's what. Diving into it, I see the AXIS_REF_SM3 function block provides uiDriveInterfaceError and dwErrorId, but I can't find any significance of these further than Drive interface error number Parameter number: 1014 and Drive specific error identifier, parameter number: 1031, respectively. Is there some corresponding appendix I could use to decode these? Also, is there any relation to the Error ID (of type SMC_Error) of the MC POUs? MC_Jog, MC_Reset, MC_MoveRelative, etc? If so, are the above errors redundant? Thanks in advance.

Post by esave on Softmotion Axis Controll ^{CODESYS Forge talk (Post)}
Hello everybody I have two of these EtherCat CiA402 stepper driver from Leadshine: https://www.leadshine.com/product-detail/EM3E-556E.html I want to controll them. I already have implemented them in Codesys with Softmotion. I see the position, the velocity and the status word so I can read everything. See picture 1. But when I want to write something like MC_Power or MC_MoveAbsolut with the SM3_Basic library it wont work and with the MC_Reset POU it shows: "SMC_R_DRIVE_DOESNT_ANSWER". See picture 2. Can somebody help me? Thanks a lot esave

Post by joep on Custom robotics kinematics model debugging ^{CODESYS Forge talk (Post)}
When trying to move my axis using any group move instruction I get the following error: SMC_CP_INVALID_PATH_ELEM and axisgroup goes into errorstop state. I tested my methods thoroughly which makes it hard for me to debug. Are there some hidden rules I need to abide to? How would one go about debugging a custom robotics model, since the information inside isn't accesible. Is it possible to find the source of where the function breaks? Any hint in the right direction would be appreciated. Best regards

this is a security issue not to read/write in the plc allowed path I would recommend to update and change the path in the application were the files are😏

Thank you for the return. The path targets to a CFast card. User has R/W access to it. We will try to change it.

Select in tree "DEVICE", right-click and select "Update Device" Select "Library manager" and Change the version of the Library (down manualy). Samoetimes "Try reload Library". If you open a project version 3.5.19 in version 3.5.16, there are difficulties.

I'm now circumventing the problem by creating a separate TCP client for all Write actions. Upon registering a changed variable, I enable this client, until the change is processed.

It would be such a simple fix to first check if the file is missing or changed before writing to it, onedrive only has a problem because codesys writes to the file every second no matter the change.

Only idea I have is that new textlists are not loaded with an online change. When you add them, maybe you always have to do a full download first.

Hi, Yes this should be possible, you should find the CodesysControl.cfg file on your plc. Open this with a text editor, and change the placeholder filepath for alarms. You can find the Placeholder filepath in the CodesysControl file under Sysfile.

it could be due to security settings. In codesys IDE, go to device-> change run-time security policy, and click the checkbox that says "Allow anonymous login". try if this works.

Should work by using the property Dynamic bitmap - Bitmap version. Change the value of the variable you linked to this property after you updated the image. See: https://content.helpme-codesys.com/en/CODESYS%20Visualization/_visu_elem_image.html
