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 ;-)

Post by niloufar on Execution Order of Function Blocks ^{CODESYS Forge talk (Post)}
Hi, Our program incorporates various function blocks and programs written in different languages such as St and SFC. They implement numerous actions and methods using different languages from their function blocks. My question is whether the execution order of function blocks is associated with the programming languages used. I understand that cycle time can be configured in the task configuration, but I'm curious if there is a specific sequence order of execution for function blocks written in different languages. For example, all function blocks in (ST) are executed first, followed by the execution of (SFC). Specifically, when the function is written in (ST) and the action is implemented in (SFC). I modified all function blocks in the main PLC program and configured a task configuration for the main program.

Post by tama00 on Datenübertragung mit SSP0 zw. uC und Raspberry Pi mit Codesys Runtime ^{CODESYS Forge talk (Post)}
Hallo zusammen, ich arbeite derzeit an einem Projekt, bei dem ich einen Microcontroller habe, der Messwerte über die SSP0-Schnittstelle an einen Raspberry Pi senden soll. Diese Daten sollen dann in Codesys für eine Soll/Istwert Vergleich/Regelung verwendet werden, und das Ergebnis soll zurück an den Microcontroller geschickt werden. Meine Frage ist, ob es möglich ist, diese Kommunikation über die SSP0-Schnittstelle (als SPI frame format) zu realisieren, oder ob ich auf eine 'reine' SPI-Schnittstelle des uCs zurückzugreifen muss. Gibt es spezielle Dinge, die ich beachten muss, um diese Datenübertragung erfolgreich in Codesys zu implementieren? Ich wäre sehr dankbar für Ratschläge oder Hinweise, wie ich dieses Vorhaben am besten umsetzen kann. Vielen Dank im Voraus!

Try using an Ethernet/IP scanner instead of an adapter, I'm guessing the 2 devices you're trying to communicate with are adapters, you have to have a scanner somewhere and Codesys should be a scanner. I don't know why you're getting the error, you should be able to use your Ethernet port as an EthernetIP adapter (although I've never had a reason to try,) but it's probably not what you wanted to do, unless you're connecting to another PLC that is a scanner. Good luck configuring the devices you're trying to connect to, it will be a lot easier if you have an .EDS file instead of starting with a generic module, even with an .EDS it can be tricky getting the communication working.

Post by arundara on OPC UA Server Stops after 5 consecutive disconnections of ethernet port ^{CODESYS Forge talk (Post)}
Hello Every one, During testing of OPC UA communication between UA Expert software and the CODESYS SoftPLC on a Linux environment, an observation was made. When the Ethernet cable was disconnected and reconnected with 2-minute intervals, on the 5th attempt, the OPC UA connection failed to establish in UA Expert software. At this juncture, restarting the CODESYS SoftPLC enabled the reestablishment of OPC UA communication. The same result was obtained when testing on a Raspberry Pi SoftPLC. What is the reason behind this phenomenon? and whether there are settings to stop this behavior? Please help. Thanks & Regards.

I recognized that I have to start the two services "/etc/init.d/codemeter" and "/etc/init.d/codemeter-webadmin" in the docker container as well. If I do so, then the command "cmu -x" returns root@sensoredge-field-netfield-produktmanagment:/# cmu -x cmu - CodeMeter Universal Support Tool.

So this time there is no indication any more that "Codemeter is not running". But still we are getting the error when using the license manager in CODESYS development system.

Post by dhumphries on How to determine code size ^{CODESYS Forge talk (Post)}
I'm trying to determine which Codesys Control license I need, the Control Standard S has all the features I think I'll need, but the code size is limited to 3mb, I created a simple program with only 1 line of ladder logic and a simple visualization with a button and an indicator. When I generate code I get some messages, one indicates that the total allocated memory size for code and data is 2.1mb. Is this metric the correct size of the code? I question the size because it exceeds the allowable code size for the Basic S and Basic M licenses and consumes 2/3 of the available memory for the Basic L or Standard S license. What tool can I use to estimate the size of code as it relates to the runtime license limit?

Post by sachem on Problem retain values Weidmuller UC20-WL2000 ^{CODESYS Forge talk (Post)}
Good afternoon. I am working with a weidmuller uc20-wl2000 controller, using a codesys license. We made a ladder code to control a process, and it works well, but we want some variables to remain stored even when the controller is turned off. We tried to use retain variables, but at the time of loading the program, when we went offline from the controller, the program was deleted, it did not remain in the controller, and in the same way if we turned off the controller. In addition to this, when we tried to program it again, the program would not stay loaded and began to present errors with the opc-ua communication. What could be causing this problem? How can we maintain the values of the variables without damaging the program or affecting the controller? thank you

Post by fontrap on cmDongle Raspberry Pi issue ^{CODESYS Forge talk (Post)}
Good morning @eschwellinger, After some research I found out that the problem is the preinstalled CodeMeter on Raspberry Pi. As I mentioned the CodeMeter was installed on the Raspberry because I use a license from other vendor that needs the CodeMeter to be installed. The problem is that when I uninstall the CodeMeter from Raspberry I am able to detect the dongle from CODESYS and everything works as it should be but now the other product can not detect its own license. When I reinstall the CodeMeter I am back to the initial problem. Is there a way to overcome this conflict through CODESYS?

Post by fajean on CODESYS control on RPi starts, shortly runs, then exits ^{CODESYS Forge talk (Post)}
4.11 appears to solve the problem. Thanks for your help. I had first installed the 64-bit version of RPiOS, but looking at various posts and the product's page on the store which only lists 32-bit compatibility, I downgraded to the 32-bit version. I did this before trying 4.11, and it did not solve the problem. Thus my working system is 32-bit, and I am wondering if I can go back to 64-bit or not. An 64-bit OS is not listed as compatible on the store's web page, but when installing there actually is a 64-bit version listed (automatically chosen when installing on 64-bit, but otherwise greyed out). Is 64-bit supported and the website is out-of-date, or is that some kind of work-in-progress?

Hello, I have almost exactly problem already discussed here in this old thread: https://forge.codesys.com/forge/talk/Engineering/thread/03af9426eb/ However, this is quite old and I assume not completely relevant. In my case, I use v3.5.20 on windows 11, so Winpcap is no longer supported on newer OS. Also, this hint about adding entry to the .cfg file under ProgramFiles(x86) is also not relevant anymore. I guess, I need to add entry SysEthernet to this .cfg file: C:\ProgramData\CODESYS\CODESYSControlWinV3x64...\CODESYSControl.cfg like this one: [ComponentManager] Component.1=CmpTargetVisuStub Component.2=CmpWebServer Component.3=CmpWebServerHandlerV3 Component.4=SysCpuMultiCore Component.5=SysReadWriteLock Component.6=SysCpuBreakpoints Component.7=SysPipeWindows Component.8=SysEthernet But I'm not sure about Npcap vs WinpCap. Please, if applicable, update these instructions.

Hello everyone. Raspberry Pi CM4 after some 1 week of work was hard reset mannualy several times and after these hard resets User Management file was missed (when click login button, enter login/password, error: User Management File missed). Also programm can not open file via SysFile library, but this file exists and size of him is 0 bytes, but must be more any way (I keep some kind of archive via this lib). What happens, how files corrupted? Where do I need try to find this error of the codesys or system whole? In the log files of codesys nothing interesting about this happens. Thanks for reading Is this enough hold PlcLogic and SysFileMap.cfg as reserve copy in another place for restoring the programm? And how automate restoring actions if programm files corrupted?

I tried to follow the steps described in the page to implement the OPC UA subscriber: https://content.helpme-codesys.com/en/CODESYS%20Examples/_ex_opcua_pubsub.html Seems that the example provided was created with version 3.5.16.0. Now with version 3.5.20.20 is not possible to open the complete project neither convert it. Anyway, after configuring all IPs and ports used in the OPC UA connection function block but the connection state always shows DISABLED. Can someone help me to do the proper configuration of the OPC UA subscriber? Many thanks in advance.
