Post by talpade on WAGO PLC 200 750-8216 Ethernet connection to Codesys 3.5 ^{CODESYS Forge talk (Post)}
Hello, I have the WAGO PLC 200 750-8210. In addition I have downloaded the "WAGO Devices and Libraries 2.0.4.3" and installed the library into the Codesys v 3.5. I then create a new project on Codesys 3.5 and select the device "750-8216 PFC200 (WAGO)" (which I downloaded from the WAGO library). However when I have connected the ethernet cable from the WAGO device to my computer and on my codesys 3.5 i press "Scan Network" on codesys and it does not detect the device. How can I get it to detect the device? (I have put the ethernet cable from my WAGO to the computer, but it does not show the device).

Post by mp9876 on Device logon problem following fresh install ^{CODESYS Forge talk (Post)}
All screenshots are enclosed in MS Word document. NOTE; 4 questions features at the end. Any assistance would be greatly appreciated! Hi everyone, I am still having device logon problem following a fresh install Here are the STEPS I went through following a FRESH CODESYS Win 64 3.5.19.60 install on a different computer. ‘Gateway not configured properly’ when attempting to REFRESH from the Users and Groups. Then did Gateway manage and confirmed it was ok: This message popped out as it was a fresh install: YES then: Initially went with Administrator twice (user & password) but it did not like it. No device is responding to …: Continued by setting a new user Pressed OK and obtained the following message: Stopped and Restarted PLC at that point: Obtained the following: Attempted to login a 2nd time without success. Then I scanned the network to see if matching device can be detected: Only way to get it detected was to remove the tick in the ‘Hide non-matching devices…’ Attempted a WINK but got a return like this one: REFRESH either @ Users and Groups or @ Access Rights returns: Then created user ‘mp’ at Project level ang logged in: Understandably device user mp9876 was not valid for the Project. Device information A few questions comes to my mind following these connection attempts: 1- Gateway not configured properly message pops out because of a non-compatible device ? 2- Why would the device not be compatible ? 3- Any way to make the device compatible ? 4- Any ideas on how to get this connectivity problem to the device solved ?

Post by nizrahel on OpC UA server on Raspberry Pi 64 SL runtime ^{CODESYS Forge talk (Post)}
Hi all! I'm working on an home project using a Raspberry Pi 3 device with Codesys for Raspberry Pi 64 SL runtime. I would like to create the HMI interface with Siemens WinCC Unified (or Advanced) configuring the Raspberry as OPC UA server. I tryed everything, but I didn't find the way to let the OPC UA connection works using UaExpert. I tryed to use anonymous connection, authenticated connection and the ip address instead of the server name in the path connection. There is no way to connect to the OPC UA server and I was asking myself if this feature is really supported for the runtime version used. Another strange thing I noted, is that is not possible to quickly create an OPC UA certificate in the Security Screen, as show in any tutorials. I have correctly created the Symbol Configuration enabling the OPC UA feature. I attach to this topic some printscreen of the actual configuration (sorry for the italian language interface, but I didn't find the way to switch to english). Thank you very much in advance for your support and advices!

Post by artplc on 3.5 P20 hangs - no response ^{CODESYS Forge talk (Post)}
Subject: Solution: CODESYS Freezes Linked to Large Symbol Configuration (OPC UA) Hello everyone, I was experiencing the same problem as many here: CODESYS (v3.5 SP20+) freezing during compilation and download, especially on projects that use OPC UA for SCADA. The only workaround was to run Build > Clean all before every download. I believe I have found the root cause and a permanent solution. The Problem: The issue is directly related to a large Symbol Configuration. In my project, I only need about 700 tags for OPC UA, but the Symbol Configuration list was showing over 250,000 tags. This is because it automatically includes all variables from Global Variable Lists (GVLs) and other memory areas. When any static variable is changed, the IDE tries to rebuild this enormous list, causing it to freeze for several minutes. The Solution: Instead of letting CODESYS export every variable by default, you can use a pragma to tell it which variables or GVLs to exclude from the symbol export process. Place the following pragma at the top of any GVL or data structure that you do not want to be part of the symbol configuration: 1 {attribute 'symbol' := 'none'} 2 VAR_GLOBAL 3 // All variables in this GVL will now be excluded from the 4 // Symbol Configuration by default. 5 InternalVariable1 : INT; 6 InternalVariable2 : BOOL; 7 END_VAR After adding this pragma to all the GVLs that were not needed for OPC UA, the number of tags in my Symbol Configuration dropped to the correct amount. The compilation and download process is now fast again, with no freezing. This method is much more efficient than manually managing the symbol list in the editor. I hope this helps others who are facing this frustrating issue. Best regards.

Post by timvh on Codesys virtual control redundancy ^{CODESYS Forge talk (Post)}
I think it depends on what you consider as redundant. Is it allowed to plug the network cable in another device (server), move the USB key with license to the other device (server) and then start it up? Or should it automatically switch over within msec and take over the communication with the I/O flawlessly without noticing the switchover? We helped several customers setting up the CODESYS Redundancy functionality and the nice thing is that when you have it up and running, you can easily switchover from active to passive and when you download a new applicaiton, CODESYS handles the update of boot project on the passive controller automatically. Sure this will require an additional license and the license for redundancy, but if your installation is that critical it should be worth it. Please contact us (Extend Smart Coding) if you need any further information. We could help you setup the configuration and possibly provide the licenses for it (I noticed you are situated in the Netherlands).

Are you sure when running as service, it is not reading configuration from C:\Windows\System32\config\systemprofile\AppData\Roaming\CODESYS... ? Is the SRV user is set for the CODESYS services? 2 ways to fix it: Change the CODESYSControl.cfg in the installation directory (ProgramFiles/CODESYS...). Replace %APPDATA% with something fix. Modify the service configuration in windows service manager to run as a different user (ie bot as Local system account)

Post by alexgooi on Disable OPC-UA server ^{CODESYS Forge talk (Post)}
Dear Forum, I recently updated to the newest Codesys IDE (3.5 SP19 patch 5) The program wouldn't download cause of the amount of OPC-UA server tags (see picture) I'm not planning on using the OPC-UA server and therefore I unchecked the "Support OPC-UA features" checkbox in the symbol configuration. But this didn’t solve the issue of the OPC-UA server exceeding its license. How can I disable the OPC-UA server while still maintaining the symbol configuration. Thank you in advance Alex

Hello, I am new on CODESYS env. I would like to do some Modbus TCP, but I am wondering If using codesys you must use the device "Modbus_TCP_Client" & "Modbus_TCP_Server". I would like to do it without device, only using ST. Is that possible ? I try the example : MODBUS_master_example, but it is not working. If it is possible to dot it without any Device I will show my code. Thx a lot

Post by timothyzalusky on Missing Device Descriptions in Repository ^{CODESYS Forge talk (Post)}
After updating my Codesys to later versions, it seems my device repository no longer lists the proper runtime devices, nor ethernet adapters, or other previously installed device descriptions. What needs to be done here? Do I need to uninstall and do a clean install? I am now updating to SP21.1 to see if that fixes it. Any tips what I am doing wrong here are much appreciated. I don't see codesys control win, or have the ability to add an ethernet adapter in my project.

Hi, I want to use Maxon IDX drives for some simple robotic applications. I have used Maxon's Epos for generating a DCF file to import in Codesys (attached). Then I can add the IDX motors under a CANopen manager in the device tree. Unfortunately, I cannot add a "softmotion axis" to the IDX motors. Now I am wondering, why? Without being able to attach a softmotion axis to the device in the device tree, the use of the motor is greatly reduced... spiessli

Good day, Currently running a project on a windows 10 IPC with TargetVisu. the project starts and runs but the TargetVisu screens will not accept a touch on the monitor but will work with a mouse. I have the option to use as a touchscreen active. I did not put my license on the device just yet. Do you have to have the license activated on the device before the TargetVisu will work via a touch? running Codesys v3.5 SP 19 Patch 6, 64bit. device is Codesys Control Win v3 X64

Just adding some info regarding the issue above. Logged onto the project using dev3og5 user (see screenshots); appeared to be ok although when attempting to logon to the device message says 'currently not authorized to perform this operation on the device' (screenshot). If user dev3og5 has same permissions as Owner user; why would it not be authorized. I am at a loss; any assistance would greatly be appreciated. Thank you Mike

Post by wbj0t on Global variable access by Programms and Modbus Devices (attach device to bus) ^{CODESYS Forge talk (Post)}
Hi everyone. I use Raspberry Pi 4, one core codesys SL. I have a question about global variable access via programm when I glued the same variable to MODBUS SERIAL/TCP DEVICE holding register. So, the question: what behavior of this modifying? When I set "Always update variables (in bus cycle)" and set some task as bus for the Device, then in another task I cant change this varible (can, but immediatly the old value setted again). But the same things works with MODBUS SLAVE: again "Always update..." and master attached to some task, then I change variable in another task and all works. I cant set up my variables from retains file at PrepareStart event because of this behavior with MODBUS SERIAL/TCP DEVICE. Thanks, wbj0t.
