Post by gseidel on Limit Axis CNC Jerk using SMC_Polynomial_AbsMaxLocs ^{CODESYS Forge talk (Post)}
Dear josepmariarams, this (internal) function has been removed with SoftMotion 4.17.0.0. We do not have public functions to compute the extrema of a polynomial. On which polynomials exactly did you call SMC_Polynomial_AbsMaxLocs? (Maybe if I understand better how you limit the jerk I can come up with an alternative.) There is no functionality to limit the jerk of individual axes in the CNC. With SMC_LimitDynamics, you can limit the velocity and acceleration of cartesian (X/Y/Z) and additional (P/Q/U/V/W/A/B/C) axes, but not the jerk. And with a quadratic ramp type you can limit the jerk on the path. Best regards, Georg

Post by cd-tt on cannot connect ot linux runtime: device does not answer the scanrequest ^{CODESYS Forge talk (Post)}
I have the following setup: Proxmox PC with a debian 13 VM running CODESYS Control Linux SL and Edge Gateway. Installation method was through the Deploy Control SL and went rather smoothly. In my Device Tab I find the gateway and when scanning my network I also find my runtime. I want to connect and get promted that I should add a user. After setting up the user I get an error saying, that the device is not responding my scanrequest. Deploy Control SL Operation saying everythings up and running. I can confirm that from the terminal on the VM with "systemctl status codesyscontrol" and "systemctl status codesysgateway". I am running out of ideas how to fix that issue. Can anybody help? Screenshots attached.

I believe I have installed the correct device descriptions and library, in an attempt to use the MCP3008 in conjunction with RPI; when project runs the MCP3008 is unable to find the correct driver. Is there anything I'm missing? Very new to this so any help is apprecated!

Post by i-campbell on Official MQTT-Client: MAX_RECEIVE_BUFFER_SIZE_EXCEEDED ^{CODESYS Forge talk (Post)}
I can't answer why it's not resetting, but from the description of g_udiMaxReceiveBufferSize, I would guess the sum of sizes of the mqtt packets received in one cycle exceeded this value. So the answer may be to increase that parameter. https://content.helpme-codesys.com/en/libs/MQTT%20Client%20SL/Current/MQTT-Client/Common/Params/MQTTParam.html https://content.helpme-codesys.com/en/CODESYS%20Development%20System/_cds_dlg_library_parameter.html

Post by tk096 on Some 'pathetic' errors in SoftMotion program ^{CODESYS Forge talk (Post)}
Hi, I suppose that you are referring to the error code "SMC_FB_WASNT_CALLED_DURING_MOTION"? Starting of Softmotion version 4.15.0.0 the instance path of the function block that has not been called is logged into the device log. This might help you to identify why it has not been called.
