Post by vincentger on using ADS1115 ^{CODESYS Forge talk (Post)}
Any reason the ADS1115 wouldnt work with SP20.1 and Runtime 10.0.0.0 on the Raspberry Pi . Using Bullseye or Buster i run into the same issue: Libary and integration works in general as described above BUT i am seeing "bleeding" between the analog inputs . Specifically consecutive ones: So sometimes the raw from AI1 shows on AI2, AI2 on AI3, .. AI4 on AI1. Even with filtering i cant smoothen that out properly and i feel like something is wrong. Almost like the bus is stumbling over itself, or the request from Codesys to the device.

I am configuring a Lenovo M900 computer with CODESYS Control RTE SL 3.5.20.30. I use an Aoc E2272pwut LED 21.5 monitor. The touchscreen works perfectly in the Windows 10 PRO environment but does not work in the WebVisualization environment (Window opened at PLC startup). Does anyone know if it is necessary to configure any drivers in Win RTE? I am at your disposal for any questions. Thank you.

Post by s1ack on PFC200 Will soft-container & IIoT license survive a firmware update? ^{CODESYS Forge talk (Post)}
I have an IIoT License activated on a PFC200 with older firmware 2.08.32 (11). If I flash it to the latest available 4.05.10 (27) does the license get destroyed? I have a back up file '3SLicenseInfo.tar'. But this looks quite a bit different form the backup I got from more modern firmware... 'CMLicenseNew.WibuCmRaU'. Can the new license manager restore it from the old .tar?

Hello everyone, i'm having some problems commanding AS1060 step motor with EL7041 (rev22) drive. With motor i've also the incremental encoder (05.2420.1230.0200.5009). I can correctly move the motor in "Position controller" operating mode with the internal counter. The problems start when i set the Encoder in feedback type or i change the operating mode. Does anyone have experience with these two terminals and can give me some advice of main parameters to check or change? Thanks everyone

Post by aliazzz on Runtime licenses not detected => DEMO Mode 2hour ^{CODESYS Forge talk (Post)}
Hi! After upgrading all my licensed runtimes to V4.14.0.0 (= RaspberryPi SL, LinuxSL and ControlWin x64 SL) I found out via the logfiles they all defaulted back into DEMO mode while all runtimes have a USB dongle inserted. So, my main question is how I can get the Dongle license detected? I use License Server 4.14.0.0 and Edge Gateway 4.14.0.0 on all platforms Any suggestions are welcome.

Post by bruno-roth on Read "Homed" status from EtherCAT drive ^{CODESYS Forge talk (Post)}
Hello, the information if your axis is already homed you could only find out direct from your Slave. In DS402 status there is no Bit defined. But some manufacturer of Drives use some optional bits or status. E.g. if you have Schneider Electric LXM32 Servo you will find this information in Bit 15. You have to check the manual of your used Servo-Drive f this information is provided in any object and then read it out with SDO.

Update, installed 3.5.19.70 with the same result. The error message is as useful as a chocolate fire guard. The container SN is in the 130-xxx range which should work. The Version, Chip, Rev number don't mean anything to me. There is no SD Card installed. I've also reinstalled a fresh Wago FW22 image, Deployed PFC200 SL and Edge for Linux, still the same result.

Hello, I'm using Codesys 3.5.20.0 version and I noticed that even with the most basic standard project create, there are error messages like shown in the acttached picture. The similar questions are already asked here on the CODESYS Forge Talk, but remained unanswered. Exact screenshot is attached, but essentially I would like to know which component in the Codesys has CmpID = 0x00000019 and what this Timeout means?

Post by timvh on Codesys Runtime Devie Password ^{CODESYS Forge talk (Post)}
This has been moved because of security reasons. But it depends on how you start CODESYS where the project files are located (at least for Control Win from SP20). 1) If you start it through the sys tray icon, you start it as a service and the files will be located in: C:\Windows*System32\config\systemprofile\AppData\Roaming\CODESYS... (or C:\Windows*SysWOW64**\config...) 2) If you start it as a user, e.g. with a shortcut to the runtime, you can find it in: C:\Users\<your user="" name="">\AppData\Roaming\CODESYS...</your>

Post by pernockham on Inheritence of struct, ^{CODESYS Forge talk (Post)}
Interesting, thanks! Didnt know about ANY before, and will sure find a use-case for it. Im not sure it will help me here though, it seems to me that an ANY will not accept a string assignment? I actually think that the "ALIAS" should work, that was a hard found error. I had a fair bit of scratching my head looking for misdirected pointers before I understood what was (not) happening. I will use the work-around of individual structs instead.

Post by josul on Web Client HTTPS Communication Issue ^{CODESYS Forge talk (Post)}
Thank you for the suggestion. There is a certificate created in the quarantine directory relating to the URL used for the webclient FB. This certificate should have been valid as it was created only the week before this problem was encountered. I investigated a separate location using the same https URL and it has 2 certificates in the same quarantine directory, 1 is created almost 200 days ago, the other over 100 days ago. There have been no similar problems encountered with these certs or https at all.

Hey tk96 Thank you for your help. I have found the reason why fbreader stuck. It was not the program but it was the gcode itself. G21 command blocks the reader. And multiple G codes in a line also blocks the reader. My code was: N010 G21 G17 G90 -> Blocked the reader When i change it to: N010 G90 N020 G17 Then it worked. The only thing i did not get is why the reader did not thwor error. ErrorId was SMC_NO_ERROR. Anyway, it is now working. Thanks again.

I need official assistance with the following issue: During EtherCAT communication, if a slave station drops off the network or the master station encounters an error, the problem can currently only be resolved by performing a software-based hot reset. In actual production environments, this approach is unacceptable. Is there a method to resolve these issues programmatically, through code?

I would definitely try using the "Reconfigure" function block from "CAA Device Diagnosis@ library. https://content.helpme-codesys.com/en/libs/CAA%20Device%20Diagnosis/3.5.17.0/CAA-Device-Diagnosis/Function-Blocks/Reconfigure/Reconfigure.html#:~:text=This%20function%20block%20reads%20and,take%20effect. Although I have not tried it with Modbus, I had great success with EtherNet/IP, Profinet and EtherCAT. You can also have a look at the other functions in this library. There are useful functions to help iterate through all the nodes under a master node.
