I/O Allocations

This section explains the operation method of I/O Allocation taking the example of
Analog Input Modules. The operation method for Analog Output Modules is the
same as for Analog Input Modules.
1) I/O Allocation Items
I/Os must be allocated to use the Analog 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
• Mode
• Service Scan (Normal/High-speed scan)
