I/O Table Settings

2-13-1 Memory Required for Units and Inner Boards

Note

2-14 I/O Table Settings

used in the CPU Bus Unit Setting Area by all of the CPU Bus Units and the
Inner Board does not exceed this capacity. If the wrong combination of Units
is used, the capacity will be exceeded and either Units will operate from
default settings only or will not operate at all.
The following table shows the number of bytes required in the CPU Bus Unit
Setting Area by each Unit and the Inner Board. Any Unit or Inner Board with a
usage of "0" does not use the CPU Bus Unit Setting Area at all.

1. Units that are allocated no bytes do not use the CPU Bus Unit Setting Area
at all.
2. When duplex Ethernet communications are used, twice the listed memory
will be required (i.e., memory will be required for two Units). With Duplex
Controller Link communications (CS1W-CLK12/52-V1), memory is re-
quired only for one Unit even though two Controller Link Units are mount-
ed.
3. Only for Process-control CPU Units.
4. Only for Single CPU Systems.
The following settings are used in the I/O tables on the CX-Programmer.
Note Refer to the CX-Programmer manual for Units not listed in the table.
