DP master interface
The DP master interface on the DP master module is used to connect the
distributed I/O (slaves). Transmission rates of up to 12 Mbaud are possible.
The DP master interface can be configured to be a DP master or to be inactive.
As a DP master the interface requires a configuration. Slaves can be operated
when the configuration is loaded; PD/OP functions and routing are possible.
The interface is always inactive when there is not configuration.
