Allocating I/O Data
Section 9-2
Two-point Output Units
Four-point Output Units
Two-point I/O Units
Note Upper bits indicated “not used” for two-point Output Units are unused bits.
Treat unused bits as follows:
• Unused bits in bit output area: Use 0.
• Unused bits in bit input area: 0 is input.
Four-point I/O Units
Bit Slave Units are allocated node address areas in order without leaving any
bits unused in the middle. For example, eight, two-point Slave Units are allo-
cated one word. Likewise, four, two-point Slave Units and two, four-point Slave
Units are also allocated one word.
