Hi, CODESYS Control Standard S + CODESYS Visualization L, CODESYS Control for Beaglebone 4.11.0.0, CODESYS V3.5 SP20 + (64-bit) I have problem that license manager say that this device is not supported when i try active whole license. When I select only runtime and communication it is go next step, but then I no have license on in Visualistion section, all of rest of software metric licese is ok(IO, Istances of com et, code size etc.). Thanks!

I ran into a problem. Uploaded an example (https://content.helpme-codesys.com/en/CODESYS%20Examples/_ex_uacapi_example.html) After launch. on the emulator. I see that I am having problems: - UaExpert does not connect. There are many servers but no connection. - I can’t transfer the certificate from quarantine to trusted ones. There is some problem with creating the certificate. CS 19.2. If anyone has had similar problems, please give me advice. Thank you.

Post by ph0010421 on General question about library versions ^{CODESYS Forge talk (Post)}
Hello I can't find anything to read on the subject so I'll ask here. Up to now, when adding a (for example) Modbus Master, I've selected the version <= the RT version, so if I'm using SP13 Patch 3, I can use a library that doesn't exceed this. I've no idea if this is correct, but it's always worked. Can someone explain the 4.x.x.x libraries that have appeared; are they tied to a RT version? The controller I use is now at SP18Patch60, so should I continue to use 3.5.xxx or change? thanks

Post by swe-hob on call of a method of a function block in another program ^{CODESYS Forge talk (Post)}
Hi, Let's assume following: PRG_1 fb_1 : fbExample1; fb_1.method_1 do something... PRG_2 fb_2 : fbExample2; fb_2.method_2 if xTest then PRG_1.fb_1.method_1(); end_if; Is there a reason why runtime hangs when I call the method_1 in PRG_1 from a method in PRG_2? Both programs run in the same task. No chance that any other program calls the method. What I practically do there is that in the program PRG_2 I add a structed object into a buffer. In PRG_1 I just process the items in the buffer.

Post by xnoop on MBTCP Slave configuration ^{CODESYS Forge talk (Post)}
Hello, I use Codesys 3.5 SP18 Patch 4 (64 bit) My Codesys project is composed of several dozen of Modbus TCP Slaves. I want to configure each of them by define : - Modbus TCP Slave Configuration : Name, IPAddress, port - Channels - Mapping I can't afford to configure manually and I need to find automatic way What possibilities does the Codesys offer? 1. I know it possible to use python script to create Modbus TCP Master and Slave. But I don't find anyway to create Channels and Mapping through the API 2. I 've tested to set mapping with file.csv on a Modbus Tcp Slave, but no way to import channels definition from file 3. I 've tried to use PLCOpenXml file. For example I 've create a project with an Ethernet device. I've exported it in PlcOpenXml file. After delete the Ethernet device, I've imported the PlcOpenXml file without success. I've tried the same by creating Modbus TCP Slave. Could you help me to find to good way ? Thanks

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 kenth1973 on MC_Phasing state explenation ^{CODESYS Forge talk (Post)}
My MC_Phasing FB was stuck in iPhasingState=1 and error output HIGH on one axis. I could manually overwrite the state to 0 in the instance data. During normal run I see the state change from 0 to 10 to 100 back to 0 (maybe more states that I couldnt catch with the naked eye) But - what are the states numbers and their different explenations? This is not explained in the FB guide on codesys. (the pictures show state = 0 after I reset)

Post by youness on CSVReaderInit returns error : INVALID_HANDLE ^{CODESYS Forge talk (Post)}
I have Already the same problem when i'm trying to write data more than 10 times in the same file. In fact, i send my data periodicaly to a file that i configured to have permission of W/R in my CodesysContol.cfg. When the Error occurs, i must reboot my machine to success. It means that the problem isn't realted to a limitation of size, but a problem in the function supposed to handle the file. totorovic : allow me to know if you've found a solution to your problem. Thanks.

Post by valenting on License problem with Raspberry Pi ^{CODESYS Forge talk (Post)}
Hello, I have a raspberry pi with a license installed, but Codesys stops after 2 hours, and when I start it manually I have the following message: pszInfo=!!!! no runtime license - running in demo mode(~2 hours) I tried using License Manager, and got the following message: Licensing info not available. There is no dongle attached to the device. I have this message frequently, and usually removing the content of /var/opt/codesys/.cmact_license makes it work. After doing it and restarting Codesys, I have an empty Softcontainer without my License. I tried using "Install license" using the .WibuCmRau file for the corresponding license and got the following message: Licensing info not available. The device does not support this service. I also tried using Additional Functions > Restore Licenses with the Ticket ID and got the following message: This device does not support automatic license backup. How can I reinstall the license to this Raspberry Pi?

hi @eschwellinger Thanks for the hint. This is what I get with "cmu -x" There is no Dongle. I think that I'm trying to install the soft container from CODESYS development system, where I have the licensed installed in the License Repository. The development system gives me the error when I try to install the Soft Container license. # cmu -x - CodeMeter Universal Support Tool.

Post by rk-gaw on Unhandled exception and refactoring error ^{CODESYS Forge talk (Post)}
Hello everyone. I hope this is the right place to ask for help, this error is causing me a great amount of time loss and I really would like to end this nightmare. I don't know why but at times if I try to Browse -> Display Cross Reference on a variable Codesys just crashes. I'll attach the file with the complete crash report hoping someone can figure why it happend. I think that the unhandled exception comes from the PersisranceManager Module and is connected with the other big problem I'm facing: I cannot refactor in my project, if I'll try to refactor a POU name the whole POU will become "frozen", it's like its desynchronizing from the project and the project cannot find the pointer to the POU once I refactor it. And when I open the project a warning pop-up will show up with the frozen POUs name, but I cannot figure out what the warning is telling me. I'll attach every warning and error pop up the project is showing me, and thanks in advance to anyone who can figure something out.

Post by nxbp on About Compatibility ^{CODESYS Forge talk (Post)}
Let's say I have a CODESYS controller (PLC) with a runtime version around 3.5.19. If I use development software version 3.5.21.40 or a later version that will be released in the future for programming, could there be any problems or malfunctions in the controller's program execution or in the execution of the new, updated function blocks from the newer software? I mostly work with servo-based motion applications, so please keep that in mind when answering, and provide a detailed answer so I don't have to email you again about this topic.

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 ;-)

Can anyone shed some light on this issue im having. at random, sometimes days, sometimes weeks or months. i get this error and have to reset the plc. Im using a Weintek HMI with ethernet/ip remote io and vsd. i have tried increasing my task times and watchdogs. and when i view my PLCload in the shell its normally around 3-4%, highest ive ever seen is 7%. Nothing i do seems to help the issue. Could the HMI's Codesys CPU be getting to hot do to high ambient temp?

Post by konstantin on Lenze i950 Servo and WAGO PFC200 ^{CODESYS Forge talk (Post)}
Hello, In our workshop we have a Lenze i950 servo drive that has an EtherCAT bus and CiA402 compatibility. The WAGO is PFC200 750-8212 and as per documentation it has built-in license for SoftMotion Light functionality. It is not capable of supporting the full SoftMotion functionality like gearing and synchronizing. I added the EtherCAT esi files from Lenze and the EtherCAT master does see the drive, then I added a SoftMotion Light Axis object. The problem is that I can only energize the axis, I cannot execute any other commands. I set the positive and negative torque limits from the PDOs to 200% and when I try to move the axis by force it does not move back to its original position. I use the SML function blocks from the PLCOpen library and the error from the function blocks is that the op mode cannot be changed. Then I tried using a standard SoftMotion axis object and everything works fine, except the MC_Home function block. The axis moves back to its position when forced out of it. I follow this guide from Lenze - Lenze i950 CODESYS V3 What could cause this issue with the SoftMotion Light axis object? Best Regards Konstantin Kolev

Post by lukasz on Unresolved reference when trying to upload to Codesys Runtime V3 ^{CODESYS Forge talk (Post)}
Hello! I'm working with Codesys SP21 Patch 4. The project builds without any errors. When trying to upload my project to Codesys Runtime V3 x64 I get a lot of Unresolved Reference errors, all with FU- at the start and then -CLOSELAYER2, -GETBUSINFO, -GETFRAME etc. I also get a error pop-up that I should 'update device' in the project but it's not specified to which version or anything useful really.There's also not much to choose from. When I check Runtime version in the systray I get 3.5.21.40 and it's the same as I have set up in the project as the device. All information I get is that it should be clear from the errors but no useful information is provided in the errors. Do I need to install some library? I checked other posts and for different reference error and this was the answer. Thanks in advance!

Post by iliyatsukerman on SoftMotion auf PFC200 ^{CODESYS Forge talk (Post)}
Hallo, Wir würden Ihre Unterstützung bei der Überprüfung der Kompatibilität der folgenden Konfiguration sehr schätzen: • PSTR-LO-16/400FEV ELMO • SCALANCE XC208 • WAGO PFC200 750-8213/40-010 • Die SPS (WAGO) wird gleichzeitig eingesetzt als: o EtherCAT-Master zur Kommunikation mit einem Elmo-Servoantrieb (EtherCAT-Slave, 4 Achsen – generisches CiA 402-Profil), und o Modbus-TCP-Server zur Kommunikation mit einem Siemens Modbus-TCP-Client, welcher zur Fernsteuerung des Elmo-Servoantriebs über die SPS dient. Bitte bestätigen Sie, ob die SPS in der Lage ist, diese Dualfunktion — als EtherCAT-Master und gleichzeitig als Modbus-TCP-Server — ohne Konflikte oder Performanceprobleme zu unterstützen. Insbesondere interessiert uns, ob die CODESYS SoftMotion SL Basislizenz (2305000000-F) notwendig ist, um 4 Servoachsen zu steuern, und ob diese Lizenz auf einer WAGO PFC200 SPS mit CODESYS Version 3.5 Service Pack 19 Patch 40 oder höher unterstützt wird. Alle Achsen im Servoantrieb werden unabhängig voneinander gesteuert. Mit freundlichen Grüßen. ILIYA
