I/O Allocation Methods
Reserving I/O Words for Expected Changes
1,2,3...
If the system configuration will be changed at a later date, changes to the pro-
gram can be minimized by reserving I/O words in advance for future Unit
changes or additions. To reserve I/O words, edit the I/O table with the CX-Pro-
grammer.
I/O Table Editing Operation
1. Double-click IO Table in the project tree in the main window. The I/O Table
Window will be displayed.
2. Right-click the slot for which a word is to be reserved and select the Dum-
my item from under the Basic I/O Unit with the correct number of I/O points.
Note 1. Do not execute the I/O table creation operation after completing the above
editing operation. The reserved word settings will be lost.
2. The following High-density I/O Units are not Basic I/O Units, but Special I/O
Units. These Units are allocated 10 words/Unit in the Special I/O Unit Area
(CIO 2000 to CIO 2959) based on their unit number settings. Refer to 8-2-
2 I/O Allocations to Special I/O Units for more details.
