  • data acquiring means for receiving a predetermined amount of data from an external device during a single data reception period and having a buffer to receive and store the predetermined amount of data;

    a nonvolatile memory;

    writing means, connected to the data acquiring means and the nonvolatile memory, for writing the data stored in the buffer to the nonvolatile memory;

    determining means for determining whether the entire contents of the buffer have been written to the nonvolatile memory;

    signal sending means for, when the determining means determines that the entire contents of the buffer have been written to the nonvolatile memory, thereafter sending only a single request signal to the external device to request the predetermined amount of data to be sent to the control system, said single request signal being the only signal sent to the external device between successive write cycle operations and there being no other signal sent during or between successive sending and writing cycles;

    the predetermined amount of received data being a multiple of an amount of data which can be written to the non-volatile memory during one write operation.
