Post by lordsteve on OPC UA certificate upgrade ^{CODESYS Forge talk (Post)}
Hi, I have the same issue. It should be possible to create a certificate without using Codesys IDE. The functionality of the security agent could be handled in some fb. Can anyone here give the right hint?

Post by spiessli on Objects in OPC UA Information Model ^{CODESYS Forge talk (Post)}
Hi, I have an OPC UA information model with objects defined in it. I can import the model and use the data types defined in it and create instances of these types. These instances are accessible at Root > Objects > DeviceSet > CODE[...] > Resources > Application > GlobalVars > OPC_UA_Symbols for created instances and at [...] > Programs > PLC_PRG for mapped instances. The object defined in the information model is accessible in UA Expert by the name I have defined in the information model (Manipulator) at Root > Objects > Manipulator. How can I assign values to the Variables defined in the object "Manipulator"? Cheers, spiessli
