Post by khaledkhalil on Import OPC UA model to Codesys ^{CODESYS Forge talk (Post)}
I have added a models in SiOME which a software to design nodes and add instances. and created a resultant xml file. I tried to import the xml file to Codesys through OPC UA information model Repository the problem i don't know how to view my objects which i have designed. and map it to my PLC to make viewable on my server UaExpert. I watched the tutorial video https://youtu.be/aJhzN3Uk-Do?feature=shared. But it only give you how to add the Information model, and my resultant model doesn't have information type. So how in Codesys i can view a model which i have designed in SiOME and mapped my instances (Objects, Variable or methods) with my Variables in PLC I saw people do it in Tia Portal or other Software, but i have no clue how to do it on CODESYS

Post by alexgooi on Codesys OPC DA server requires more then 2 GB of ram ^{CODESYS Forge talk (Post)}
Dear Forum, We are currently running into a problem that the CODESYS OPC DA server is running out of RAM (larger than 2 GB). We have a setup of 10 Codesys controllers which features around 300.000 discoverable tags per controller. We are only interested in 10 percent of the tags to be communicated to the OPC-server, this is due to the fact the program consists of arrays of objects which on their part implements arrays of objects, simply reducing the number of discoverable tags is not an option The OPC-DA server loads all the discoverable tags, is it possible to: 1 let the OPC-DA server only load the tags that are requested by the SCADA/MES system. 2 let the OPC-DA server claim more memory. 3 run 2 OPC-DA servers in parallel? Thank you in advance

Post by bryandimino on OPC Da Server Code Meter Issues after Enabling License ^{CODESYS Forge talk (Post)}
I'm trying to get the OPC server setup on my machine and currently I'm not having luck. I went ahead and got my license setup. However when I go to run WinCoDeSysOPC.exe I get an error message that I don't have the code meter licenses installed. Does anyone have any ideas on how I can fix this issue?

Post by ofey on two different OPC clients with different privileges ^{CODESYS Forge talk (Post)}
Hi! I have usually only connected one OPC client (our system) to an OPC server created in the codesys environment on a PLC. This OPC client has a lot of write privileges. A customer also want OPC access, but I want to restrict his access to only read certain values. Do you know if this is possible inside the single codesys runtime running on a controller?

it is mandatory to activate the OPC DA license into the 32-xxxxxx legacy container (not UFC) you need a remove ticket -> contact CODESYS store - my question to move the license
