Post by stiller on OPC UA RPI 4.8.0.0 Status Code / "out of range" ^{CODESYS Forge talk (Post)}
Hello, I have an OPC-UA server with an information model. For many values, there is a defined range (e.g., 0 to 100). If a client enters a value outside this range (e.g., 120), the StatusCode should change to Bad. How can I accomplish this? Any help is appreciated! Thank you in advance. Best regards, Christian Stiller

I am using the Data Source Manager with OPC-UA Client to get data from another CodeSys application in the same Project. How can I check in the PLC_PRG structured text if the connection is ok or not?

Post by ekristoffe on Modbus UDP ^{CODESYS Forge talk (Post)}
UDP has no packet ordering mechanism, and Modbus protocol has no order checking mechanism nor session establishment. I'm sorry but this is false, Modbus IP based have the Transaction Identifier. Transaction Identifier - It is used for transaction pairing, the MODBUS server copies in the response the transaction identifier of the request. Modbus UDP make more sense than Modbus TCP in a local environment.

Post by madskaizer on Exception when OPCUA datasource disconnects from Server ^{CODESYS Forge talk (Post)}
We have similar issues, with crashing PLCs, but this ranges from 3.5.16.40 to 3.5.19.70. Which log made you confirm the exception crash? I am currently looking for evidence of what causes our PLCs to crash. Network stability could be an issue with latest security roll-outs like 802.1X and segregation.
