Post by bitwitch on Einheiten umrechnen, Numpad und Eingabegrenzen ^{CODESYS Forge talk (Post)}
Das Codesys-Objekt 'Einheiten umrechnen' wirkt auf timeVar (TIME) z.B. innerhalb eines Visu-Rechtecks und funktionier in den Grundfunktionen einwadfrei. Die Ausgabe der Std. von timeVar läuft. Beispiel: Bei t#3d2h10m wird wunschgemäß 74h (volle Std-Anzahl). Die Grenzüberwachung Max= 10 funktioniert nicht, da die Angabe scheinbar ms erwartet (arbeitet mit 10ms). Irgend wie muss man jetzt codesys davon überzeugen, dass auch für Min und Max die Einheitenumrechnerei wirken soll, wobei die Eingabe der Grenzen in Std erfolen muß. Hat jemad einen TiPPPPPPPPP?

i know, this is the reason for us either. PLC-Handler is to big, and only available with additional Contracts/Costs. OPC-UA is to slow for us. As described, there is a solution available, but im not allowed to post them here. i would prefer you send a message at codesys store by "have a question" or similar called. Not sure. Or, if an Codesys-Official Member allows to share that informations, i can give you the right hints.

Post by wollvieh on License Activation Problems ^{CODESYS Forge talk (Post)}
on a raspberry pi delete the folder and its content before licensing. /var/opt/codesys/cmactlicense If you plug this SD card in another raspi ( which has another hw-serial number) you'll get a second empty softcontainer. This could lead to an unlicensed PFC (it could only handle one container) The solution is: To delete the /var/opt/codesys/cmactlicense directory and content of it and then aktivate the lizenz via WibuCmRau file and Lizenzmanager.

Post by sajid on NMEA Serial data read in Control win v3 x64 ^{CODESYS Forge talk (Post)}
I am using the SerialCom example program from the CODESYS website to read NMEA strings in CODESYS Control Win V3 x64 through a serial-to-USB converter. However, I occasionally receive only partial data or encounter errors in the received string. A screenshot of expected NMEA string attached for reference. Could you please advise on how to ensure the full NMEA string is received consistently? Error in strRead variable is <value of="" the="" expression="" cannot="" be="" retrieved=""></value>

Hi I recently started learning Codesys SoftMotion. At first, I mainly used YouTube videos. I stopped at two videos where the same problem keeps recurring. fbReadPos( Axis := X_Axis, Enable := TRUE, Position => gAxes.lrActualPos); <- axis cannot move I checked the entire code line by line. Zero errors. GPT spits out nonsense, throwing up increasingly worse errors. And when I copy its code, it says the code is wrong and gets stuck in a loop of its own stupidity. Can anyone explain why it doesn't work? Link to the video below: https://www.youtube.com/watch?v=CYa2HvYZgbM&list=PLsEhEcYjG7na0OveU7cqFXBx7ATyGGn0A&index=3

You can definitely pull the actual system time into CODESYS without too much trouble. Take a look at the SysTimeRtc or SysTime library—both let you read the current date and time from the Raspberry Pi. You can call SysTimeRtcGet() or SysTimeGetTime() in your PLC code and then format the hours, minutes, and seconds into variables that feed your 7-segment visualization. Once you’ve mapped those values, your Visu display will update automatically each cycle. It’s a pretty common approach for clocks in CODESYS, so you should be able to get it working quickly. golf hit

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.

Post by hackehucke on Mithilfe von SysSocket eine Verbindung herstellen ^{CODESYS Forge talk (Post)}
Hallo zusammen, vorweg: ich habe sehr sehr wenig Ahnung von Codesys, industrieller Kommunikation etc ... Ich soll für ein Seminar mithilfe der Library SysSocket eine HTTP Verbindung zwischen PC und und der Wago PFC200 herstellen, die wir hier im Labor haben. Ich habe mir unterschiedliche Examples von Codesys angeschaut, ChatGPT gepromptet etc. aber komme nicht in die Nähe von irgendwas, das funktioniert. Kann mir jemand ganz einsteigerfreundlich erklären, welche Bausteine ich benötige und was mit diesen getan werden müsste, um das ganze zum laufen zu bekommen? Wäre auf ewig dankbar ... Verzweifle hier langsam :( Viele Grüße

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 farren on Codesys complains about matching versions ^{CODESYS Forge talk (Post)}
I'm building up a 2nd PC to match an existing developer PC. Installed the same SP and Patch levels but when I open a project that was created on the existing PC, Codesys complains that it's not the same version. Attaching a screenshot..... What else is there to match? Also, can all of the libraries that are on the existing machine be copied from it to the new machine and if so, how? (So I get the same versions) Which files/folders do I copy? Thanks! -Farren

I guess you could archive the project, open the archive and go online. Is that suffiecient for your use case?

Guess you could just add two modbus slaves with the same ip, to enlarge the 10 channel limit.
