MPI Controller / PROFIBUS-DP Slave General Description The profichip MPI12x is a communication chip with processor interface for MPI applications. The MPI12x handles the message and address identification, the data security sequences and the protocol processing for PROFIBUS, which is the underlying transmission protocol. Token handling, error detection and data pre-processing is executed out automatically by the MPI12x, relieving the host processor from all time-critical tasks and time-consuming arithmetic operations. Support of data transmission rates up to 12 Mbit/s, the integration of the PFOFIBus protocol into hardware, 4 KByte communication RAM and the configurable processor interface are features to create high-performance MPI applications. Alternatively, the MPI12x can be used as a Serial Interface Device supporting synchronous and asynchronous standard protocols as well as user defined protocols with data transmission rates up to 12 Mbits/s. Moreover the well-known PROFIBUS Slave Core VPC3+C (extended by DP-V2 service "Clock Synchronisation") is integrated as well. Features: MPI communication up to 12Mbits/s PROFIBUS-DP Slave incl.
