With an operator terminal with RS 232 interface, a connection to an MPI bus is established via the HMI-RS232 MPI box. Its main purpose is to adapt the RS 232 interface to the RS 485 bus system of the MPI interface. In the transport layer (layer 4), the MPI box uses the RK512 protocol. For further information, for example on the parameterisation of the MPI box, please refer to the MPI box manual.
