Post by winki on Not Possible to connect using control SL ^{CODESYS Forge talk (Post)}
Hello, I used to connect into my gateway using control SL tool 4.13, (it was called Update Linux.) I formated my computer, so today I install the new version of codesys and all package. Now I am not able to connect to my PLC using control SL. It says, check the status. Normally it used to worked perfectly before that.

Post by teichhei on The selected container ... does not fit your ticket ^{CODESYS Forge talk (Post)}
After correspondence with Mr Schwellinger from Codesys the resolution for this was to uninstall the SL 4.14 and install SL 4.13 on the device. Once this was done the licensing worked as expected. I noted that the container then showed a Version 3.00 and not 0.00.

Post by pernockham on Preferred way of managing Ip-adress/es for linux (debian) host? ^{CODESYS Forge talk (Post)}
I have a debian linux host running Control SL. I tried to manage IP-addresses through codesys/Control SL but that was not successful. What works though is manually editing the network-interfaces config file. /etc/network/interfaces. Is there a way to set this up so that IP-addresses can be managed from within codesys instead? Thanks! / Per

Hello, many thanks for your reply. I checked the logs. It seems that dll is not loaded. However other dll such as the Webserver are loaded. Could you tell me what I need to do such that my dll is loaded. (Furthermore I changed the C-Function a bit. I used the M4.exe from the SDK.) Many thanks.

Post by atone on Set DeviceID of an IO-Link Sensor at Runtime ^{CODESYS Forge talk (Post)}
Answering to myself: is not possible according to the IFM support, this possibility has not been taken into account, although the interfaces and FBs in Codesys would apparently support it. So I ended up having to deactivate the sensor validation and the backup & restore functionality in the master and implement it in the PLC myself.

Post by atone on Change IO-Link Device Interface connected to a Profinet-Slave at Runtime ^{CODESYS Forge talk (Post)}
OK, I figured out that I can simply define all the sensors as 16 bytes IN/OUT, even if they are not all used. EDIT: The negative effect is that each bit is taken into account as an I/O for the license, even if not used.

the Answer is easy, you don't reapecting the codesys-behaviour and pre-request on a dll/so like you like to create. codesys won't load it about the fact that the dll isn't registered in codesys. check this page for more informations: https://content.helpme-codesys.com/en/CODESYS%20Control/_rtsl_extension_extension_sdk.html

hi imdatatas, thanks for your suggestion! I added the process execution to be sure. In the meantime I reïnstall Windows but it dind't help directly. Finally I deleted CodeMeter Runtime Server after Codesys installation. Because this Service was not able to start. And it works (for now) :)!

Post by timvh on Reading multiple lines from csv file ^{CODESYS Forge talk (Post)}
Not sure, but maybe before you enter step 5, set i, lineindex and charIndex to 0. And the buffer variable should have a size bigger than 1 line. Additionally I think you should set bufferstart to 0 before you enter step 5. And in the OSCAT function you always point to the buffer address, but shouldn't this be (buffer + bufferstart)?

Hi, which CODESYS Version are you using exactly? Either update to 3.5.21.x if you are on 3.5.20.x if not - add a more secure pw. Seems that on adding the login credentials it is mandatory in 4.16.0.0 -to have complianct to password policy seems a bug that the message not occure.

Post by rajatdas2005 on Codesys Virtual control SL ^{CODESYS Forge talk (Post)}
Thanks once again. Right now the codesys virtual control sl docker is using the host ip itself not the docker ip. so the local host edge gateway was able to search the virtual plc. so you are telling me instead of local host edge gateway I should use the edge gateway docker version?

I am currently having the issue that Codesyscontrol only runs for 10 seconds on my Raspberry Pi 4. I believe the problem is because the MAC address range is of the Raspberry is 88:A2:9E:XX:XX:XX. When will Codesys Control For Raspberry Pi 4.17.0.0 be released to fix this issue?

Post by sandro66 on Application-based license Modbus Channels ^{CODESYS Forge talk (Post)}
Hi, I imported an old project created with version 3.51.20.50 into the new version 3.51.21.20. I'm using ModbusFB.ClientTCP v4.5.0.0. Strangely, I can no longer download the project due to a licensing issue I didn't have before. The number of Modbus channels has gone from 1 to 54!, and there's no license that would work. Can anyone tell me where I'm going wrong? Thanks Sandro

Hello yann, In the past I have experimented with the execution of Linux commands using Codesys. Maybe this article helps: https://www.linkedin.com/pulse/run-linux-commands-from-codesys-jouke-aalvanger When you are able to execute Linux commands in Codesys, you can run the Python script.

Enabling Anonymous Login 1. Navigate to 'Device' > 'Communication Settings' > 'Device'. 2. Next, click on 'Change Runtime Security Policy'. 3. In the new window, find and check the box for 'Allow anonymous login'. After completing these steps, you should be able to communicate with the OPC UA server.

Gateway and runtime (Control for linux SL) on a debian linux. Thanks for your check. Good to know. I will probably travel there in about a months time so that will give me better possibility for further testing. (on a side note, I dont get mail-updates on forum-subscriptions, need to check the topics manually)

Hi, I’m evaluating CODESYS for our devices. If I buy a standard runtime and the Toolkit, can I create a custom device descriptor so users can select my device (instead of just “CODESYS Control for Linux ARM64 SL”) when starting a new project? Has anyone done this or know if it’s possible? Thanks!

I tried both 3B en 4. But every time with a lite version. I didn't try the full version of raspberry pi os. Nice to hear you are aware of the problem and trying to fix it. I'll hold on to the image from 2023-10-10 for now.

Same issue here: Raspberry Pi 4 Model B HW 1.5 Regardless of the image (tried 32bit / 64bit version from Raspberry Pi Imager- all the "standard version") and with all tested Codesys Control versions (4.2.0, 4.8.0, 4.10.0) and regardless if single core / multicore / 64 bit variant.

Post by dhumphries on Execution Order of Function Blocks ^{CODESYS Forge talk (Post)}
Function blocks in a SFC are executed left to right, top to bottom, instructions in ST are executed from left to right top to bottom as well. I think you are asking about the execution of POUs although you use the name function block, I believe POUs are executed in the order they are shown under the main task.

Hi! I'm still on the hunt for drivers for example TCA9548 and a list or somewhere where all devices for raspberry is gathered. as this post is quite old I'm hoping/gussing that there is somewhere where work after 2021 is gathered? Or has the raspberry part if the community slowed down on creating device drivers?
