The MDT should be read and written at a processing station. First, 32 bytes should
be read from the MDT address 0x0110, then 60 bytes should be written from the
MDT address 0x0100. The MDT status is also transmitted in order to allow any errors
in the MDT to be addressed.
The actual link state is read in an event-oriented manner to determine whether or
not a new MDT is in the link. The link state is contained in the event-oriented data
channel by default and is, e.g., provided in the input map in PLC systems.
The remaining data is exchanged with the MDT directly in the CONNECTED state. The
MDT then signs off with the commanded link state RECONNECT. The SLK switches to
the CONNECTING state to wait for the next MDT.
SLK preparation
The SLK switches to the link state CONNECTING with the command-oriented data
exchange.
