1. A circuit for coupling a field bus and a local bus, the circuit comprising:
a field bus controller that is equipped to send and receive process data over the field bus;
a local bus controller that is equipped to send and receive the process data over the local bus;
a data management unit connected to the field bus controller and the local bus controller, the data management unit being equipped to transfer the process data between the field bus controller and the local bus controller;
a memory area connected to the data management unit to copy and store the process data; and
a processor connected to the data management unit and connected to the memory area, the processor being equipped to set up the data management unit so that the data management unit copies the process data into the memory area, and the processor being equipped to read out the process data copied in the memory area.
