About the Siemens DP/DP coupler

It consists out of 2 DP slaves which continuously copy the output data to the input data of the other (and vice versa). The slaves have to be integrated in the configuration of the masters (every master controls 1 slave).

The outcome is a mailbox with a maximum of 244 bytes input and 244 bytes output. The networks can have different baudrates and bus parameters. The bus addresses of both slaves can be set by 2 DIP switches.
