Post by mohammedben on Fail communication between CODESYS and Fuxa SCADA via OPC UA ^{CODESYS Forge talk (Post)}
hi, When I try to establish communication between CODESYS and Fuxa SCADA via OPC UA, the connection fails, and I receive the following error: 2026-02-15T08:38:13.618Z [ERR] 'codesys' connect failure! Error: The connection may have been rejected by server, Err = (ClientTCP_transport6: socket has been disconnected by third party) 2026-02-15T08:38:13.619Z [ERR] 'codesys' try to connect error! Error: The connection may have been rejected by server, Err = (ClientTCP_transport6: socket has been disconnected by third party) 2026-02-15T08:38:13.622Z [ERR] 'codesys' connect error! undefined (1) Note that there are no problems when I establish communication with the UaExpert and OPC UA Client Simulator software. I also previously tried communicating with RapidSCADA and received the following error: Endpoint with the specified security options not found. And when I try to connect with "none" in the security policy, I get this error: BadSecureChannelClosed I have tried almost all the solutions available online and have not found a solution. I hope you can provide me with a solution that solves this problem. Thanks in advance

Post by paulg on Converting hex bytes to float ^{CODESYS Forge talk (Post)}
I'll be capturing a hex stream over serial into a RasPi and I'd like to convert a group of bytes into a float. I see this is available (https://content.helpme-codesys.com/en/CODESYS%20Development%20System/cdsoperatorrealto.html) but not its inverse (i.e. BYTE_TO_REAL). The packets will be 18 bytes but I'll be selecting 4 byte segments from the middle, swapping byte endianness (i.e. changing 0x51847641 to 0x41768451), and converting to float; I believe they adhere to IEEE 754. Is there a pre-built function for some or all of this, or do I need to follow (https://forge.codesys.com/forge/talk/Engineering/thread/dc5829c7ea/)? Thanks!
