– The number of displayed words is the number of words of a block displayed in the Network Config-

when uploaded, the number of displayed words will be set to 100 and displayed.
Specifying Auto-allocation at Registration
• If the option for auto-allocation (Auto-allocation as is registered) is selected, words will be allocated for I/
O automatically in the order of registration when slaves are registered to a master in the Edit Device
Parameters Window. This option is effective only in the Edit Device Parameters Window.
Auto-allocation allocates words starting from unused words in Block 1 of the corresponding I/O memory
block in the order of registration (i.e., in the order slaves are dropped).
• Deleting or changing I/O allocations for the selected slaves (allocating unused word) can be performed
anytime by clicking the Auto Register/Unregister Button.
