Post by salvadegianluca on SysPlcCtrl23 and C0338: The library 'cmperrors interfaces, 3.5.5.0 (system)' is supported just in 32 bit applications ^{CODESYS Forge talk (Post)}
Good afternoon to everyone; I'm stuck with this error and I don't know how to get out from it... I tried several time googling for alternative systems to control the PLC applications and resets but without success. I would like to realize the possibility to reset the CPU and to start/stop the applications as it was possible with the SysPlcCtrl23, but this library is no longer supported in 64 bit systems and it seems due to the cmperrors interfaces sub library that was included in the above said one. Someone found a work around for this issue?

Post by kazuhiro on Problems using MySql Library and SysProcessExecuteCommand2 together ^{CODESYS Forge talk (Post)}
I use fbMsSQL_compact(FUN) of the MySQL Library to write data to the database. There is no problem when writing data using only fbMsSQL_compact(FUN). However, when I try to write data obtained using SysProcessExecuteCommand2 to the database using fbMsSQL_compact(FUN), an error message "Dest server on ip address:xxx.xxx.xxx.xxx and port:1433 is unreachable" appears and writing is not possible. From what I have researched, it seems that writing is not completed in one cycle of fbMsSQL_compact(FUN), and when SysProcessExecuteCommand2 is executed first in the second cycle, the work done in one cycle of fbMsSQL_compact(FUN) is reset. Could you please give me some advice?

For anyone confused with the process visit this link (the bottom section about creating a .pfx file) https://content.helpme-codesys.com/en/LibDevSummary/certificate.html#import-of-client-certificates-with-private-key. I solved this problem by creating a .pfx file and importing it into the security store under 'Own Certificates'(must have SP18 or newer to import .pfx). I used a gitbash shell to enter the openssl command that created the .pfx file. Once you import the file, in your TLS context, set your 'sUseCaseName' to be the same as the name listed in the 'Information' column of your imported certificate. This did it for me

Post by uluking on CodeSys2.3 Modbus 64-Bit Double Read Problem ^{CODESYS Forge talk (Post)}
Hi everyone, I would appreciate your help with a problem I've been working on for a few days but haven't been able to resolve. I am reading data from a Siemens PAC3220 energy analyzer using Modbus with Wago-8202. However, the device's energy indices are given as doubles. Since a double variable is 64-bit, it is not possible to read it directly. I have been struggling for days, I have written many conversion functions but I have not been able to get results. I would appreciate your help. I read 4 word variables and processed them. I am converting them according to IEEE-754, but I can't seem to read the correct data. I would appreciate your help.

Post by wchin on Passing EtheNetIP adapter device into a Function Block to access it's IO ^{CODESYS Forge talk (Post)}
We are creating helper function blocks for our VFD(EtherNetIP). How should I set it up so that I can pass the device into and out of the Function Block so that ideally I can access the IO of the device by devicename.channelname. So something like for example we have a VFD with a start bit that is in the ControlWord channel and a SetVelocity that is a channel. And we want to create a Function Block called StartVFD. So I declare something like: FUNCTION_BLOCK StartVFD VAR_IN_OUT device: ioDrvEthernetIP.RemoteAdapter; END_VAR VAR_INPUT velocity : REAL; So in the code it would look something like device.SetVelocity := velocity; device.ControlWord.6 := True; We have a pretty basic eds file for our VFD and can update it if necessary. Thanks in advance.

Post by tali on Configuration of disabled/deactivated visu elements ^{CODESYS Forge talk (Post)}
would be great to have such fucntionality. Sometimes it is not clear for user which elemetns are blocked and which are not - the greyed out eleemtns are not so different for low resolution / low quality screeens. What I have in my mind as well is to have a possibility to detect the visu Element clicked on and get its Access Rights. If it is blocked/deactivated, the dialog can be rised with INFO 'please login first with proper rights'. It is possible now to have a Mose event Handler ( Examples -> EventHandler) and rise the dialog out of ST (Exapmpals -> ST Dialogs). I am struggling still with getting the separate Visu Element under the mouse and its structure info

Post by gseidel on Can't get SMC_SmoothPath to work ^{CODESYS Forge talk (Post)}
Hi bertus, I cannot see any problem in the code you posted. Just some ideas: What is the value of D_ANGLE_TOL? - Do you need the assignment bAbort := NOT bDecoder? Does it help to leave it out? Any errors (e.g. SMC_SmoothPath.Error/ErrorID) or PLC log messages? What if you comment out SMC_SmoothMerge and SMC_LimtiDynamics, is corner smoothing still not working? Is bDecode written from a different task (e.g. visu)? Then I would recommend to assign to a local variable (bDecodeLocal := bDecode) and use that for all FBs. Otherwise, FBs might see different values of bDecode in a single cycle, which will cause problems. Regards, Georg

Post by pernockham on Unable to deploy "Control for Linux SL 4.18.0.0" ^{CODESYS Forge talk (Post)}
The option to update "Control for Linux SL" is not shown in the "deploy control SL tool", I can see and update the gateway but not the control (3.5.21 SP4). Has the way to update control SL changed? In the process of fault finding I removed the control SL entirely from my target, then I had to revert to version 3.5.21.0 SP 1 to re-install "Control SL 4.17.0.0". So I thought it was just a matter of using SP1 to update also to 4.18.0.0, but after installing the files for 4.18.0.0 in the SP1-version, the behavior was identical to SP4, ie no Control for Linux SL shown in the deploy tool.. See screenshots.

PLC — XSA-330L, rev. 1.2, drivers — DC5C2 (rev.5) In the task configurator, all tasks are set to simple numbers (11, 13, 41 ms) for convenience. The jitter for EtherCat and SoftMotion tasks is less than the task cycle (2 ms jitter for a 6 ms task). The power supply is sufficient for both the PLC and the motors. The cables are in good condition. Please suggest where to look for the problem. P.S. The PLC uses proprietary Linux and there is no SSH access.

I think google has fooled me here, the only thing I can conclude so far is what i now from reading the licenseManager, which tells me that my valid license have the following product-code CONTROL - 16#3000 VISU - 16#3003, feature map: 1000 COM - 16#3004, feature map: 0200 Will different level of license give different product codes or will I see the active license level by other means? What I am trying to achieve is block Starting a machine with time limited operation should the application be larger than what the license permits (DEMO-mode). And give this information to the user by an alarm/information.

Post by gseidel on SMC_Interpolator / CNC Abort – ControlAxisByPos Sometimes Remains Busy and Axis Continues Moving ^{CODESYS Forge talk (Post)}
Hi kishan, I would recommend to first execute a stop (input bSlowStop or bQuickStop of the interpolator). Only when the interpolator has stopped you should abort the interpolator and preprocessing FBs. BTW., a new rising edge of the execute input should suffice. In case preprocessing is done in a different task: take care to write the abort signal to a local variable in the path and interpolation task and use this local copy. (Otherwise, some preprocessing FBs might see an abort and others not, in the same cycle of the task.) Best regards, Georg

Post by mascara on JOG continues in WCS ( SMC_GroupJog2 ) ^{CODESYS Forge talk (Post)}
I'm using the SMC_GroupJog2 block from the SM3_Robotics library for manual movement of an AxisGroup in WCS coordinates. The observed behavior is: When pressing X+, the X-axis starts moving correctly. If I press Y+ during the movement, the block interrupts the current movement and starts a new movement in X and Y. If I release any button, all axes stop, even if another button is still pressed. Example: Pressing X+ → X moves Pressing X+ and Y+ → X stops momentarily and starts XY movement Releasing X+ while holding Y+ → all axes stop The expected behavior would be: to allow simultaneous continuous movement on multiple axes to not interrupt movement when another axis is added or removed. Is there a correct configuration of SMC_GroupJog2 to achieve this behavior, or is there another block more suitable for continuous manual jog in AxisGroup (WCS)?

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

Post by baotthitawat on SCADA Systems Are Becoming Easier to Integrate With Modern Applications ^{CODESYS Forge talk (Post)}
One thing I’ve been seeing recently is that more industrial systems are starting to expose realtime SCADA data through APIs instead of keeping everything isolated inside the local monitoring software. This makes integration much easier for cloud platforms, mobile dashboards, AI analytics, and enterprise applications that need realtime industrial data. Instead of exporting reports manually or building complicated middleware, APIs allow external systems to access SCADA data directly in realtime. I think this becomes especially useful for applications like wastewater treatment monitoring, where operators need better visibility into alarms, equipment status, and operational conditions across different locations. Feels like modern SCADA is slowly evolving from a standalone monitoring platform into part of a larger connected industrial ecosystem.
