Disculpen, tengo unas dudas acerca de una comunicación de un PLC S5 95u con una PC que se utiliza como SCADA/HMI. No me deja comunicarme con el PLC, ya tengo la aplicación de WinCC e instalado el WinCC en la PC, hay una máquina gemela con la que he cambiado PLC y en la PC que ya tiene no hay problema de conexión, por lo que por parte del PLC no debería haber problema, pero al momento de querer hacer lo mismo en otra PC para actualizarla en la otra máquina no me deja hacer la conexión. ------------------------------------------------------------------------------------------ Split from WinCC Flexible and S5 PLC.

This is an international community, and we try to focus on one language. Posting in English will help you to get more response to your question. This is the translation of your question: AutoGen_1934123 Hi how are things? Excuse me, I have some doubts about communication between an S5 95u PLC and a PC that is used as SCADA/HMI. It doesn't let me communicate with the PLC, I already have the WinCC application and WinCC installed on the PC, there is a twin machine with which I have changed the PLC and on the PC that it already has there is no connection problem, so on the part from the PLC there should be no problem, but when I want to do the same on another PC to update it on the other machine it won't let me make the connection. Regards, Jen_Moderator

I´m not sure if I understand correctly (an own translation of your questiontext would help), you have two winCC flexible RT stations that should connect to one S5? hen It could be a matter of communication ressources. s5 only alows few connections at the same time. stop the other runtime and have a look if the connection then works Bye Murof
