Hi all, I am attempting to use the Control Win V3 soft PLC to control a WAGO 750-315 remote I/O system via modbus RTU communication. I am struggling to connect to the device. I have been following this tutorial: https://www.youtube.com/watch?v=YlRfkESaNds I have setup my devices as shown in the images below. I have verified that my com port settings are correct as I am able to connect/control using modbus simulator software with these settings. I have also connected to a modbus master simulator program as instructed in the video, but the orange triangles will not go away. Additionally, I have updated my settings to 485 using the PLC shell. I have also set "always update variables" to enabled (1). Serial port, PCI-Bus, and modbus serial device status all show as "Not Running."

Hi, yes i did solve it. You have to change the namespace 0 model in the UaModeler. Open the modeler --> Settings --> Edit Settings --> scroll down to the last option "External Model Support" --> Check "Allow replacing built-in..." Now create a new project in the UaModeler. If you have to choose your base models, you can see the option "Find another Opc.Ua.NodeSet2". I have attached the .xml i am using.

Add existing version (with SM drive) - without scan - disable under expert settings in the slave the revision check.

Hi yr00, the default sampling interval is set to 1s. you can generate your own client settings, this link should help you:- https://content.helpme-codesys.com/en/CODESYS%20Communication/_comm_use_dynamic_opc_ua_server_comm_settings.html

Hi! I'm sorry if this has been asked before. I have tried looking up previous topics regaring this, but even though I'm following tutorials and other posts I cant seem to get this to work consistently. I actually got the connection established on a test project after some trial and error. I only got it to work with the "Anonymous login". But after i deleted the test project and tried to get the same thing to work on another project I cant get it to work anymore. What I'm trying to do: Set up and OPC UA Server using CODESYS with the free soft PLC. I then try to connect to the OPC UA Server with the program "UaExpert". What happens: I get the error Error "'BadUserAccessDenied' was returned during ActivateSession". What I have done in CODESYS: - Added the object "Symbol configuration" and checked some test variables - Checked "Support OPC UA features - In "Communication settings -> device -> Change runtime security policy" I have checked "Allow anonymous login" What I have done in UAExpert: - Found the OPC UA server under "local". (It is showing two servers though, I do not know why. It showed the same when it worked yesterday). Se attachment - Checked "Anonymous" under "Authentication settings in the OPC UA server. I'm new to CODESYS, so it could be something elementary wrong in my settings. Maybe something in the user settings in CODESYS regarding user rights or something?

Thanks for the answer. So yes I've enabled expert settings, and yes i've added some SDOs, but some of them who are generated are likely making a mess in the network and generated error with my device... From which library comes those 2 function blocks ?

Most likely related to the Device Diagnostics functionality. Double click on your device (PLC), go to the tab "PLC settings". Enable the advanced option "Enable diagnosis for devices". Build your application again.

Maybe also good to know that you could use the CODESYS installer to switch between gateways. - open the CODESYS installer - Select the (hamburger) menu - Select Settings - Select Services Then select the Gateway you would like to use.

Go to Online>Communication Parameters...>Gateway>TCP/IP> Click on "New..." and reestablish your connections with whatever IP address and set up information you have. Bypass whatever is necessary as you may have to redownload to the PLC.

I am having the same trouble. However, if I change the Login Configuration settings to 'Type: Login using the credentials determined at runtime' then the Connection information continues as 'Connection state: Connecting' and 'Error information: OK'. There is no User Management on the source PLC.

Is is possible to use the compiler "Fix Version" in SP18+? I have noticed that in SP17 and below, the option is available in the compiler options under project settings, but in versions 18+ it is unselectable. The help topic does not provide any information.

it could be due to security settings. In codesys IDE, go to device-> change run-time security policy, and click the checkbox that says "Allow anonymous login". try if this works.
