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

Hi ustad41, cams can be buffered using the BufferMode input of MC_CamIn. If the end- and start-velocity of two buffered cams are not zero, there will be no stop. Not sure this answers your question. Cams can be changes on the fly by aborting the active cam. Please see [0] for details on switching cams.

1) Based on your first screenshot. Do NOT filter on "Phoenix". Then first select the Ethernet adapter (of CODESYS) and add this to your device. 2) Then to this Ethernet adapter add a Profinet Controller of CODESYS. 3) Then to this Profinet Controller, add your Phoenix Profinet coupler/adapter.

Thank you Pernockham, I am using Windows SoftPLC and the device is CODESYS Control Win V3 x64. In the above attached example, the file is Linux-based. This is an external add-on file in the CODESYS installer (CODESYS Control for PLCnext SL). I am trying to implement it without this add-on file.

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.

Hi liai, I tried it with a fresh CODESYS SP21 Patch 2 installation and SoftMotion 4.18, but cannot reproduce the compile errors. Could you please upload a project archive that has the errors? Then I can have a deeper look. https://dl.codesys.com/s/q4KcbKCcZndg6oR Best regards, Georg

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)

Hello. I'm using Visualization XY Chart, and when I mark a circle through XY position data, a blue line is displayed in the circle with a red circle. At this time, can't I set the blue line not to be seen in the circle? Currently, whenever XY position is drawn, the line follows.

Post by snhatton on How to write a for loop in ladder? ^{CODESYS Forge talk (Post)}
Hi there, little late to the party, but you could also use the ST block for in-line ST code and implement a for loop as you normally would. ST Block is super handy if you just need a small amount of in-line structured text code without creating a new POU. Hope this helps!

Post by arjunk on How to correctly create a device descriptor (.devdesc.xml) for a custom Linux ARM64 PLC in CODESYS 3.5.21.20? ^{CODESYS Forge talk (Post)}
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!

Post by snhatton on OPC UA: How to change NodeId ?! ^{CODESYS Forge talk (Post)}
You can change the node id by adding the following to /etc/CODESYSControl.cfg: [CmpOPCUAProviderIecVarAccess] CustomNodeName=MyPLC123 Then restart the runtime and the new Node name will appear with the connection. I don't know if it's possible to remove the |var| from the name. I hope this helps!

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.

Hello. I created a project that uses SPI. This project is working well. I can see with an oscilloscope that the SPI pins are actually changing. But when I resave this project in the IDE and open it later in the system, I see a constant error. What do I need to fix? What am I doing wrong? Thank you.

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?

So none of the images from the 64bit archive work with any Codesys Control versions? I have tried the last Pi OS with every Codesys Control version and they don't work. I was wondering if there's any stable combination of versions.

Post by tvm on Cannot pass array of constant size to a function as a reference ^{CODESYS Forge talk (Post)}
It will be a reference, because it's a VAR_IN_OUT. it's a little weird debugging the array online. It just shows as a POINTER TO INT, and you can't actually see the array from the function side. But you can still work with it as a normal array, not a pointer.

Have you found a solution for this? Id be thankful for every hint. I have a controller with the same events in log and sometimes it crashes. Memory of the codesys3 task rises until the linux system kills the task because the controller runs out of memory.
