Post by darwin03 on Mismatch between coordinate monitor and actual motion using SMC_GroupJog2, MC_MoveLinearAbsolute (6DOF) ^{CODESYS Forge talk (Post)}
Dear Georg, Thank you for your explanation about the axis scaling. I checked the scaling of Joint6 and corrected it so that one technical unit equals one angular degree. However, I am now facing another issue. When I move all axes to zero position and then try to use SMC_GroupJog2 and MC_MoveLinearAbsolute, I receive the error SMC_CP_CONFIGS_DIFFER I already tried moving each joint manually to different positions before executing the motion command, but the error still appears. Could you please explain: What exactly causes SMC_CP_CONFIGS_DIFFER Thank you very much for your support. Best regards, darwin03

Importing a library overrides parameters of a referenced library ^{CODESYS Forge talk (Thread)}
Importing a library overrides parameters of a referenced library

Post by egau on Importing a library overrides parameters of a referenced library ^{CODESYS Forge talk (Post)}
Hi, In my CODESYS project (ABC.project), I’m using the MQTT library. I’ve also created a separate library (DEF.library) which itself references the MQTT library. In ABC.project, I’ve customized some MQTT parameters—for example, setting g_udiMaxPublishersAndSubscribers to 100 instead of the default value of 20. However, when I import DEF.library into ABC.project, the MQTT parameters get reset to their default values. I assume this happens because DEF.library still uses the default MQTT configuration, which then overrides my project settings. A straightforward workaround would be to manually align the parameter values in DEF.library, but that doesn’t feel like the right approach. Is there a better or recommended way to handle this situation? I'm using SP18 Patch3. Any insights would be greatly appreciated. Thanks in advance!

The OpcUa_StatusCode enum exists in CmpOPCUAStack Interfaces — how do I bind one to a published symbol so clients see the StatusCode change?

... and SP21 P6 also. Kind of bummer, migrating from TIA Portal to Codesys for PLC educational courses. These kind of bugs, and other deficiencies, really makes me regret my choice.

And also we do not have any opc ua related license . Do we need to have a opc ua license to communicate with OPC UA server with username and password?

Hi, I'm using codesys v3.5 sp21 software. I have downloaded the sample opc ua client project from https://content.helpme-codesys.com/en/CODESYS%20Examples/_ex_uacapi_example.html and i tested connecting to "prosys opc ua simulation server". Through Anonymous connection it is connecting to server and can read data. Later tried to connect using username and password. First got a SECURITY_CHECKS_FAILED error, trusted the client certificate in the server and this issue resolved. Next got an INVALID_CERTIFICATE error, trusted the server certificate in the client and this issue resolved. After these two error it is not establishing the connection and not giving any error messages. UAAsyncProp: UA.AsyncProperty := (tnTaskName:='UAClientTask', usiTaskPrio:=20, udiTaskInterval:=10000); UAPolicy: UA.SecurityPolicy := (sPolicy:=UA.OpcUa_SecurityPolicy.OpcUa_SecurityPolicy_Aes128Sha256RsaOaep, eSecurity:=UA.SECURITY_MODE.SIGN_AND_ENCRYPT); //UAPolicy: UA.SecurityPolicy := (sPolicy:=UA.OpcUa_SecurityPolicy.OpcUa_SecurityPolicy_None, eSecurity:=UA.SECURITY_MODE.NONE); UAAuth: UA.UserNameAuth := (sUserName:=UAVars.sUser, sPassword:=UAVars.sPass); UAClient: UA.Client := ( itfAsyncProperty:= UAAsyncProp, //sClientName:= 'MyOPC UA client name', //default: ‘CODESYS OPC UA Client’ sURL:= UAVars.sURL, sSession:= UAVars.sSession, itfPolicy:= UAPolicy, itfAuth:=UAAuth, udiTimeout:= 100000 //,itfNamespaceArray:= UAVars.itfNamespaceArray //optional use ); ----------------------------------------------------------------------------------------------------------------------- Please let me know if any additional information required. Thank you...

If anyone here are working with robots and using Codesys to control it and implement tasks, Please let me know. I am currently in my Master thesis and i need some advice on this. We have Pilz Robot with Codesys and I am trying to proceed with certain tasks but have no documentation for it. Would be helpful if anyone of you can suggest and help connect with the right people.

Hi Suyash, if possible update to latest CODESYS version. license should work version independent.

Thanks for your reply @eschwellinger. Update : the is problem is resolved. It was done by renaming the User database file (/var/opt/codesys/.UserDatabase.csv) as deleting it was risky. After restart the IDE asked me to create new user. On doing that the problem got resolved. Reference for members facing similar problem/s : sudo systemctl stop codesyscontrol sudo mv /var/opt/codesys/.UserDatabase.csv_ /var/opt/codesys/.UserDatabase.csv_.old sudo systemctl start codesyscontrol

Hey Guys, I am trying to create a ModbusTCP_FunctionCode06 which i will use as a single write register for programming a test code for Power Meter(PQM_1000) I have tried to reserach how to add it it from the libraray manager and have largely been unsuccessful. Does anyone know where I should Look? And by the way, I am i wam using Codesys V3.5 Vs 21 Patch 4 I look forward to something positive. Best, Kmax365.
