2.6.4 PLC/MCP/HHU interface
General
On the SINUMERIK 840D/810D, the machine control panel (MCP) is connected on the same
bus that connects the OP with the NC. The advantage of this is that only one bus cable is
required to connect the operator unit. The handheld unit (HHU) can be connected to the MPI
of the PLC or to the operator panel interface (OPI) (840D only). However, since the OP bus
on the 840D supports higher baud rates, two different types of bus topology are provided.
