MULTIPLE CPU SYSTEM CONCEPT
(3) Outputs to output modules and intelligent function modules
(4) Access to intelligent function module buffer memory
ON/OFF data cannot be output to non-controlled modules.
When the outputs of the output modules and intelligent function modules controlled by
another CPU are turned ON/OFF from the C Controller module, they are not output to
the output modules and intelligent function modules.
/* Y is read in 1 word unit */
ret = QBF_Y_Out_WordEx(path, flg, yno, size, data, datasize);

(a) Read from buffer memory
Using the bus interface function (QBF_FromBuf function), data can be read from
the buffer memory of the intelligent function module controlled by another CPU.
