3 Basic System Operation
3.5.4 Defining Function I/O
3-26
2. Fig. 3.8 shows an example of the I/O definitions of a function.
Fig. 3.8 Graphic Representation of a Function 2 (Example)
3. I/O signal addresses are automatically allocated from the highest signal on the graphic
representation. For the example given in Fig. 3.8, the allocation of each I/O register will
be as shown in Table 3.10.
Note: XW00000 and YW00000 of the X and Y registers are used for bit
data.
4. The function I/O registers shown in Fig. 3.8 are allocated automatically. The external
framework of the function is completed at this stage.
