Post by snhatton on OpC UA server on Raspberry Pi 64 SL runtime ^{CODESYS Forge} ^talk ^(Post)
Good afternoon, After changing the security settings to: CommunicationPolicy: POLICY_BASICSHA256SHA256 CommunicationMode: ALL Activation: Activated UserAuthentication: ENABLED Then generate a new certificate on the device for the OPC-UA server from Security Agent->Device->OPC UA Server. Restart the runtime using tools->Update Raspberry Pi->Stop->Start for the changes to take effect. It may take a minute for the runtime to start. Initiate the connection from the UA server side. You should see a pop-up asking you to trust the certificate. Click on the button 'Trust Server Certificate'. Next, you should see a certificate in the quarantined folder of the security agent in CODESYS. Click and drag this from quarantined to trusted and then try connecting from UA expert to the device. These steps worked for me and my setup and I hope they can help you!

Post by sean-barton on Ambiguous namespace in library dependencies ^{CODESYS Forge} ^talk ^(Post)
I am trying to install the MQTT Client SL in an existing project I have been working on for years. After adding the library to the project, and without adding any other code, upon building I get a C0180: Ambiguous namespace 'MBM' error between the memory block manager (MBM) in the NetBaseSrv dependency of the MQTT Client SL library and the memory block manager (MBM) in the CAA CanL2 dependency of the 3S CANopen stack library. I have tried: * setting "Only allow qualified access to all identifiers." in the properties for both the parent libraries. * deleting the 3S CANopen stack library. Upon (re)building the error simply points to another conflicting library - there are many. * deleting the Library Manager and rebuilding it. * adding the memory block manager library (used in the NetBaseSrv) manually and changing its namespace to MBM3S. None of the above allow me to access the MQTT library through its namespace (MQTT). Adding the memory block manager manually removes the C0180 error, but the MQTT library is not accessible - i.e. mqttClient : MQTT.MQTTClient; highlights the mqttClient as "Identifier 'MQTT.MQTTClient' not defined". Is there anything else I can try?

Post by royw on Profinet library for C# ^{CODESYS Forge} ^talk ^(Post)
Hi, I don't know if I'm in the right place or if it's even possible... I'm looking for a way to address a Profinet device with Record Read and Write from my own PC. I actually only need very few commands to configure our device. This means setting the MAC address and a serial number. We would like to do this from a C# program. Now we are looking for a library or something similar. Since you can do it from Codesys, I thought there might be a DLL or something similar that you could use for this. As I said, we don't want real-time queries of the cyclic data but only record read/write. Does anyone have any helpful hint? Thanks in advance
