Post by rabaggett on No Visu on RasPi ^{CODESYS Forge talk (Post)}
OK, I got this to work as shown above in mos89p's comment. What I did: Tools/Update Raspberry Pi. Reloading the runtime seems to have solved the web problem. I can view the visualization on the Pi and laptop using a browser as shown above. Thanks! But Isn't the visualization supposed to take over the screen of the Raspi? When I run visu projects on Windows or Wago, the visualization shows on that device's screen by default.. But this is not happening in this case

Post by ducng on SMC_FB_WASNT_CALLED_DURING_MOTION when enable MC_MoveRelative ^{CODESYS Forge talk (Post)}
Hello, I am using an Inovance PLC to control a servo via EtherCAT. When I enable MC_POWER, the drive switches to Run mode successfully. After that I call MC_MoveRelative, but I get the error SMC_FB_WASNT_CALLED_DURING_MOTION. The servo vibrates but the motor shaft does not move. I am new to EtherCAT/servo motion control, so I would appreciate any guidance or suggestions for troubleshooting this issue. Thank you in advance for your help.

Post by jonasz on Deploy LicenseServer for Linux SL ^{CODESYS Forge talk (Post)}
Hello, I'm asking for help with installing the license server for Linux SL 4.18.0.0. When I try to install it, I get a message that the WIBUCodeMeter package is missing. I checked the package manager tab to see if the package is installed, and it is - Codemeter 8.40.7120.501. I've checked the CodeMeter Runtime on the target machine, and everything seems to be working fine. One thing caught my eye: the Device Architecture tab says "None" Please help me solve this problem.

Post by marciohogenelst on stablish CAN communication through the PC's USB port ^{CODESYS Forge talk (Post)}
I'm using Codesys v3.21SP4 on my PC via ControlWin to establish CAN communication through the PC's USB port. The software works fine. The CAN/USB converter works fine and is validated. However, there is no communication. Which folder and file should be modified to allow the CAN/USB converter to work and thus achieve the connection? Converter used: PCAN-View Information not yet processed: Access the folder: C:\Program Files (x86)\3S CODESYS\GatewayPLC\CODESYSControl.cfg Uncomment the line: Component.5=CmpPCANBasicDrv Any help would be appreciated.

Hi Georg OK got it, thank you. I respect your (CODESYS) policies on that issue. Will try to update according to your recommondation if the customer experience same error in the future. Though - from within my coding heart it does bother me deeply, that I cannot get further understanging/knowledge on the iPhasingState, but I guees I will have to swollow that bitter pill and get on with it! hehe ;-)

Post by timvh on OPC UA PubSub SL 1.3 — UADP WriterGroup with assigned PSS.SecurityGroup still publishes plaintext ^{CODESYS Forge talk (Post)}
I never tried this, but maybe you need to create a certificate on the controller for this? See the menu View - Security Screen. Select the device and see if you need to create a certificate. And maybe you also need to accept the certificate of the other device. This can also be done in the security screen. PS, the CODESYS Runtime Control version must be greater than 3.5.21.0.

Post by ryusoup on 'keep last value' option in CODESYS EtherCAT ^{CODESYS Forge talk (Post)}
Hello, I’m using CODESYS EtherCAT Master on a Raspberry Pi controller with several remote I/O modules. I’m facing an issue where the input values from the remote I/Os drop to 0 when a connection error occurs. Is there a way to configure a “keep last value” behavior (i.e., hold the last valid input) instead of defaulting to 0 on communication loss? Best regards,

Post by seler on Custom button with output status ^{CODESYS Forge talk (Post)}
Just to clarify. Output for lamp will have two inputs: from plc IN (wall switch) and from visu button. Until now I had separate object for visu button and separate for visu lamp. Now I want it to be one object, bulb icone which will change color on lamp status and yet by touching it will change visu button state. Tried "Switch Image" object but there is no way to assign switch var.

Post by antonz on OSCAT Scale_r function not working in LD 4.60 works in LAD2 on 3.5.21sp3 ^{CODESYS Forge talk (Post)}
That's what I found as well Shaun. I have seen it at least in versions 3.5.21.1 and 3.5.21.3. There seems to be an issue with the FBD/LD package v4.6.0.0. The workaround proposed by Tim works but needs to be done manually on every code change/addition. For now we manually downgrade the FBD/LD package from v4.6.0.0 down to v4.5.0.0 after installation of CoDeSys. Same as you did. I hope this gets fixed on a next patch.

Post by rtlman on Scan devices hangs CODESYS ^{CODESYS Forge talk (Post)}
Hello, I have a problem that randomly appeared today. When trying to scan a network adapter in "Deploy Control SL" the whole program hangs and needs to be restarted. I have been running "CODESYS v3.5 SP21 Patch 3" for a while and it has worked without any issues until now. I've tried upgrading to "CODESYS v3.5 SP21 Patch 4" with the same result. I've not made any system settings recently that im aware of which could cause this. Has anybody had similar a issue?

I am running tests using the Windows runtime environment. The alarm history is not being logged and displays the error: "Some kind of disk I/O error occurred. Check disk space" in the alarm table. Furthermore, it is not possible to export the alarms. I have already tried to find a configuration field in Alarm storage and Alarm configuration to fix this problem, but I haven't found any related fields.

Post by spilin on All devices lost for all installed version ^{CODESYS Forge talk (Post)}
hello. After installing the latest version of codesys (3.5.20) from codesys installer, I had a problem. All my devices disappeared. Both PLCs and IO modules and network devices disappeared from my list. I browsed through the Windows files and I can find them in the programdata/codesys/devices folder. The files remain there, but they are not available within codesys (same error in all installed versions) which in this case are 3.5.16 and 3.5.19. Does anyone know how I can reimport or resynchronize my devices folder again? Thanks

Post by gseidel on CAM Motion Recover after STO ^{CODESYS Forge talk (Post)}
Dear Mr. Kolev, can you please explain a little more: what happens at an STO? I assume the slave axes will be stopped and retain their current position? How, then, do you call MC_CamIn after the STO? Do you restart it with a new rising edge, but on the same master position as before the STO? Which StartMode are you using, is the cam slave absolute or relative, master absolute or relative? Are the slave axes modulo or finite axes? Best regards, Georg Seidel
