Hello,
I faced problems with the Socket class for C++: https://api.plcnext.help/api_docs_2020-6/classArp_1_1System_1_1Commons_1_1Net_1_1Socket.html The program is allready unable to use the Bind() function, as it has 'Invalid arguments'. Example code is also not working at the setup I use, so I doubt the function call is not right. The setup is: [list] [*] Engineer 2021.9 [*] PLCNCLI 2021.6 [*] SDK 2021.9 [*] Firmware 2021.9 [/list] Does someone experienced this as well? What could be the problem? Maybe someone has a working setup to share? We did manage to run all the code with the TCP block in Engineer and connect the C++ program with ports. With that library from PxC, the PLCNext has no problems with same configurations. Thanks in advance, Arne Simac QuadCore
