Post by yannickasselin on codesys VLAN tagging ^{CODESYS Forge talk (Post)}
I ordered a cheap managed switch and tested it as soon as I received the switch. It works great! I even went a bit further. As you can see in the screenshot, I created 2 Codesys containers. Each one having 2 fieldbuses. The first one has EtherCAT and EtherNet/IP and the second one has EtherCAT and Modbus/TCP. All going through the same ethernet port from the PC to the switch. The switch splits it up into 4 different networks. The hardest part was to figure out how to configure the switch. @eschwellinger, thank you very much.

Post by andrax on CodeSys Raspberry pi I2C driver not found ^{CODESYS Forge talk (Post)}
Ok, with debug you suppress the errors, but that doesn't help you any further. You can find information about the missing drivers here https://forge.codesys.com/forge/talk/Runtime/thread/8981ce928a/ and here https://github.com/stefandreyer/I2C-Multiplex I'll have to have another look at which library you need. But you can easily find out. Create a completely empty project and insert the TCA9548. You don't need the board. Then look in the library and resolve all conflicts If you can compile the project without errors, delete the TCA9548 and insert the ADS1115. The driver should then also run. Small bonus: with the TCA9548 you can expand your network as you wish and use identical sensors multiple times

Post by hyys12 on CODESYS 3.5 dicovery of PLC modules ^{CODESYS Forge talk (Post)}
I have a WAGO PLC, to which I am establishing a connection. Here I use the autodiscover to register the connected modules. Now, I have tested the in-/outputs of the different modules, to verify they are consistent with how they are physically connected to the PLC in regards to how CODESYS has numbered them. Will CODESYS always number the modules closest to the PLC itself lowest, and the one furthest away, the highest? I am rather new to the program, so I both hope my question makes sense, as well as not being completely obvious. Thanks!

Hi, Could you please send an print of your ethernet adapter info? Ip addr Subnet Mask Default Gateway Also, check if the gateway service is active in your windows. Win+R > services.msc > Look in the list CODESYS Control Win V3 x64 Gateway OR CODESYS Gateway V3 Hook up the M12 code D into the ETH port, supply the controller, it should apperars to you. Make sure when you try to connect with the controller, the target of your project has to match with the controller. Otherwise, click on the device in the devices tree > Communications Settings tab > Device > Options > And disable "Filter Network Scans by Target ID". Good luck.

Hi, I have problem with connecting Wago PLC WAGO 750-8212/0025-0002 configured as OPC UA client to Kepware OPC UA Server. I am using Codesys 3.5.19.70. What I did so far. To the Codesys project I added object Data Source Manager and configured connection OPC UA like below: pic 1 Then I can browse the OPC server tags in “Variables” tab after prior trust on the server side of the client certificate created in the “Communication” tab: pic 2 Additionally second certificate has been created in Codesys for runtime process in “Security screen” as well as the server certificate was approved here: pic 3 But when I compiled project, downloaded it to PLC and go to RUN I can’t read selected in “Variables” tab, OPC Server tags. I am getting such error (ID: 7001): pic 4 All two PLC certificates has been trusted in OPC server (Kepware) side: pic 5 and Kepware server configuration look like this: pic 6 I can easily connect using third party OPC UA client UaExpert to Kepware server without problem. In attachment I added also log from Kepware OPC UA server. pic # - this specifies the number of a concrete graphic from one of the collective in attachment

Previously, I have used ModbusEthernet_04 library for Wago for ModbusTCP Master communicational in Codesys V2.3. How to use same communication of similar UDT for Opto22 Groov PR2 PLC in Codesys V3.5 SP20. Can I use OSCAT library - Network -MB_Client or IODrvModbusTCP - ModbusRequest for this requirement? If any other please guide.

I've post the Versions in the Attachments. It seems with htop, that there is a very high CPU Load. In the Log I can see nothing, as mentioned above I've to restart the PLC with Power off/on and the log in codesys was deleted. Or what do you mean with plclogger?

Post by kees-b on PLCnext Phoenix Contact ^{CODESYS Forge talk (Post)}
Hello We started with the new design of Codesys, through a "CODESYS Control Standard S" license. However, after installing the license, connecting, etc. (without any problems), we cannot get the program into the PLC with entries that we have not seen before. Is there anyone who has also experienced this? Better yet, does anyone have the solution?

Post by dhumphries on Using Codesys example problems ^{CODESYS Forge talk (Post)}
You have to install any libraries needed by the sample program. Click the button with ... next to one of the errors (see attached image,) then choose download missing libraries. Codesys should automatically locate and install the missing libraries, it's not flawless though, I've had some issues getting libraries to install. The best advice I can give if it doesn't work is re-install Codesys.

please tell us the exact error message from diagnostic. U can view it at devicetree in the node-element diagnostic from modbus-configuration. u also can activate the function auto-reconnect in master and increase a little bit the timeout and the repetition to male thw communication a little bit more robust

I have found a similar topic but tried to run it in C3.5.16 and the visualization crashed. https://forge.codesys.com/forge/talk/Engineering/thread/8be0f6f14a/ My question is what is the easiest way to run a dialog from ST, as we need an external device to open the dialog so we cannot use the button on the display itself.

Post by installwhat on raspistepper error after install ^{CODESYS Forge talk (Post)}
from another post on this forum .... In your library project select Project -> Project Information. On the Properties table remove the "LanguageModelAttribute" Value "Qualified Access Only". This will allow you to access the object without qualifying the access. ...... I guess they've compiled it the library with that setting and now I need to mess around with versions.

Post by dhumphries on Rounding error in simple addition ^{CODESYS Forge talk (Post)}
I have discovered a rounding error, either in Codesys or in my understanding of numbers. The attached ladder shows that when the up button is pressed the number increases by 0.1, when the down button is pressed number decreases by 0.1, after several button presses the number isn't equally divisible by 0.1. Have I discovered a bug or am I doing something wrong?

At the moment there are some changes on PI OS, which lead to problems with the PI5 an Pi runtime. I would use Arm SL or Arm 64 SL as runtime depending on which OS you have installed. just use the CODESYS Installer and deploy the the Arm runtime.
