I created an NI1 memory bit and assigned it an address of VB249.0. Now for me to read or write to this bit with Modbus/Tcp I have program in my other Plc to service address 125.

Everything works just like it's suppose to but I don't understand why?

 And I don't understand why you keep creating a new topic for the same question.

I also don't understand why you create a topic once in the German-speaking forum and then again in the international forum and then again in the German-speaking part of the forum.

Also, there is no VB249.0.
There is one bit, V249.0.
And there is a byte VB249.
