Post by antonz on CoDeSys v3.5: creating libraries for both 32-bit and 64-bit controllers ^{CODESYS Forge talk (Post)}
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?

Is there a way to not enforce password policy or change the rules for this policy? Device is a Codesys Control for Raspberry Pi 4.17.

Post by gseidel on Using an Axis of an Axis Group in Torque Conctrol ^{CODESYS Forge talk (Post)}
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

I can also add the kernel log messages from the same time. Seems like some kind of packet storm to the PLC?

Post by alexgooi on Licensing info not available. ^{CODESYS Forge talk (Post)}
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?

Post by caliberbishop on Having trouble using the Web Client SL library ^{CODESYS Forge talk (Post)}
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

you could try to uninstall 4.8.0.0 Package by the CODESYS installer - and reinstall (I would use current version) - this should solve it

Post by kevinl on RevPi Connect RS485 ^{CODESYS Forge talk (Post)}
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 ;-)

Because it starts listening on all interfaces, which is against security considerations.

Post by manuknecht on Using SMC_MOVTYP.INITPOS without specifying the start position ^{CODESYS Forge talk (Post)}
I am using the object SMC_GEOINFO to generate a trajectory and move a system accordingly using the SMC_INTERPOLATOR function block similar to the sample project CNC10_DynamicPath.project. According to the documentation, the movement type INITPOS does not require a start position in the SMC_GEOINFO object, which is confirmed in the documentation of the SMC_GEOINFO object. When using the movement type INITPOS however, the motion will still start from the starting point defined in the SMC_GEOINFO object (0,0,0 if not specified otherwise). Does someone know how to resolve this or is there an example project that makes use of the INITPOS movement type without specifying the starting point? Thanks in advance!

Post by ewi04 on Recipe Manager - RecipeManCommands, load & write wrong values, Bug? ^{CODESYS Forge talk (Post)}
Hello, according to Codesys, the problem should be solved with version 4.3.0.0. After the update to version 4.3.0.0 I had the problem that the recipes weren’t saved correctly, but loading was okay. Return to the version 4.2.0.0 didn’t change the behavior. Strange… So I uninstalled the update, cleaned the project and built it new. The known behavior of version 4.2.0.0 was back. Update to version 4.3.0.0, clean and build it new, it works. Even with version 4.2.0.0. Strange, but okay. Notice: ManCommands.LoadRecipe() no longer writes into the PLC. Just as it should be. As of now, I can use the new version.

Post by jdjennings1962 on Trouble accessing Math functions in OSCAT library ^{CODESYS Forge talk (Post)}
Hi all, I am trying to utilize the ARRAY_SDV standard deviation function, part of the Math group in the OSCAT library downloaded from the CODESYS store. My Codesys version is 3.5.19.10. When I add the OSCAT to my Library, it shows a subset of the library (Standard) as fully installed and signed (see pic). However, the Math functions are not in this Standard group. The Math functions I need can be viewed as source code in the full OSCAT_BASIC, though this the symbol next to this library suggests it is source only and not fully installed. When I try to declare an instance of the ARRAY_SDV function in a program, it is not known. I have tried reinstalling and Building . . . Any help would be greatly appreciated. Jeff

Post by askjong on Update variables when OPC UA Client updates. Error ID: 268468277 BadAttributeIdInvalid ^{CODESYS Forge talk (Post)}
Hi, I'm connecting to a OPC UA Server using the Data Soruce Manager OPC UA Client. This works well until the OPC UA Server updates and the OPC UA list doesn't match up when i did last clicked the "Update variables" to add variables. All the variables are still the exists and none are removed from the server, but more are added during the engineering process. The error message i get in CODESYS is "Error in OPC UA call BadAttributeIdInvalid, Error ID: 268468277". The issues is fixed when i press the "Update variables" button and just press ok without adding or removing any variables in the list. Is there a way to either automatically update the browsepath if it fails or on startup, or to trigger it by code?
