Post by viksym on How to get the motor scaling value from code

Is there a way to see what value is set as the "Work travel distance per motor rotation" that is set in the Scaling menu of the axis ? I am working on my own homing function block for sensorless (hardstop) homing and I want to make it be universal between different axes with different motor's scaling for distance per rev so I need to know this value from the axis itself. I know I could do it by just creating an input variable for the function block but I'm leaving that option as a last resort.

This is a phenomenon that I have seen myself and with others. Texas instruments wrote an application note with this same issue. They noted with Codesys 3.5.19.10, that selecting CPU 1 as the EtherCAT task showed CPU spiking improvements over the performance of cores 0, 2, and 3. It appears to be linked to EtherCAT, are you configuring for use with distributed clocks? If so, I recommend choosing the 'Based on Input Reference' option. I have found it to reduce the CPU usage spike maximum slightly (see attached). See link to TI (also attached in case link breaks) https://www.ti.com/lit/an/spradh0/spradh0.pdf?ts=1723546111357

CODESYS Forge

As far as I remember, the Reconfigure functionality doesn't work for Modbus devices. But... Each Modbus device in your device tree has a name. You can set the property "Enable" of this device to FALSE to stop communicating with it. So if one of your Modbus Slave devices name is "MbSlave1" in the device tree, then in your code you can set the Enable to FALSE to let it stop communicating: MbSlave1.Enable := FALSE; Please let us know if this worked on your controller with your application and your CODESYS version. Alternatively you could use the ModbusFB library. See: https://forge.codesys.com/prj/codesys-example/modbus/home/Home/

Hi, I’m currently managing over 50 PLCs running Codesys version 3.5.18.60. At seemingly random intervals, some of these devices experience a failure where: All persistent variables are lost. Attempting to log in results in the message: “The application does not exist on device. Do you want to create it and proceed with download?” The log shows: “Loading retain-data/bootproject failed.” From what I’ve gathered, this may be due to a corrupted persistent data file, but I’m not entirely sure how to confirm or resolve this issue. If anyone has encountered something similar or has suggestions for troubleshooting or preventing this, I would greatly appreciate your input. Best regards

Post by antonz on CoDeSys v3.5: creating libraries for both 32-bit and 64-bit controllers

Follow up question: in the Project Settings, under Library Development, there is an option related to this: Check all Pool Objects -> Pointer size to use Options are: * 32 Bit * 64 Bit * 32 and 64 Bit The descriptions and online help suggest to me this is only relevant for checking and showing any incorrect pointer types as an error in the IDE. E.g. using a DWORD to store a pointer value on a 64-bit controller. It would not control the creation of either 32-bit or 64-bit compiled libraries. Is that correct?

CODESYS Forge

Hi manuknecht, the axis group currently always writes the axis set torque values. If no dynamic model has been configured for the axis group, then the set torques are written to 0. The solution for your use case is to call SMC_GroupUpdate [0] before you call SMC_SetTorque on the axes. This way, the axis group will write 0 to the set torques in the call to SMC_GroupUpdate(), and SMC_SetTorque then will write the desired set torque. Best regards, Georg [0] https://content.helpme-codesys.com/en/libs/SM3_Robotics/Current/SM3_Robotics/POUs/AdministrativeConfiguration/Computation/SMC_GroupUpdate.html

Thank you for the response, The empty softcontainer does not become visible unfortunately, but I think I can get that back to working. I think I'm misunderstanding something. You are pointing to the Softcontainer number and the ticket code, I thought that I needed to fill in the virtual control containers serial code is this a misunderstanding? And if this is indeed the case, how is the link between the server (softcontainer) and the Codesys control docker container made? If I have multiple Codesys docker containers running on the same docker server, how is the correct license distributed to the correct Codesys runtime container?

Hello, I'm trying to use the Web Client SL library, I installed it in the IDE (did not purchase a license yet, as this is still a proof of concept so demo mode is good enough) and added it to the library manager. However, when trying to define a FB of the type WebClient I get a "Identifier 'WebClient' not defined" error message, setting the type to Web_Client_SL.WebClient did not work as well. Opening the example project the FBs defined there give the same error message. From the problem in the example project I deduce this is not a syntax problem, so maybe a license problem, but there should be a working demo mode, so what am I missing? IDE v 3.5.21.30 Library v 1.12.0.0 Thanks

I figured this out on my own with this logic: usually the Serial port on a Raspberry pi is on /dev/ttyUSB0 then you need to set linux.DeviceFile=/dev/ttyUSB in codesys you then must set com port to 1 so i assumed codesys subtracts 1 from the number and adds this to the filename... (in code it would look like this: var comPort : byte := '1'; linuxDevice : string := '/dev/ttyUSB'; filename : string; end_var filename := concat(linuxDevice, (to_string(comPort-1)); filaname then is /dev/ttyUSB0 RevPi uses ttyRS485 as Serial port so you must remove the last number from the name and set the com port to this number +1 i hope this is understandable ;-)

To exclude a word or phrase, put a dash in front of it. Example: docs -help
To search on specific fields, use these field names instead of a general text search. You can group with AND or OR.
