5.4.3 I/O Allocations
1) I/O Allocation Items
I/O Modules must be allocated to use the Register Input and Output Modules. I/O
allocations are made using the MEMOSOFT and the results are recorded in the I/O
allocation tables stored in memory of the CPU Module.
The following items must be set for I/O allocations.
• Module Type
• I/O References
• Service Scan (Normal/High-speed scan)
• Timeout Output (Clear/Hold)*
Note: This item is to be set only for Register Output Module.
• Mode (8CH/16CH)
• Cycle
• Select Timing
This section describes the operation method of I/O Allocation taking the example of
Register Output Modules. The operation method for Register Input Modules is the
same as for Register Output Modules.
2) Module Type Setting
Set the Module Type in the following procedure.
(1) Start the MEMOSOFT and select Online from the Mode Menu.

I/O allocations cannot be performed while the CPU Module is in RUN status. If
necessary, stop the CPU Module. For the procedure to stop the CPU Module,
refer to 6.1 PLC Operations in the MEMOSOFT User’s Manual (Manual No.
SIEZ-C825-60.10).
