Changing the Size of the Full Logic Area
Introduction The number shown in the Available Logic Area field in the PLC Configuration
screen indicates the total amount of memory available for your application logic.
You cannot directly enter this field to modify the value. You can, however, change
the amount of memory available by manipulating the size of other fields in the PLC
Configuration screen.
Example 1 For example, if you reduce the expansion size of the I/O Map, the number in the
Available Logic Area field automatically increases. Say you are using a 12.2K
machine and you change the size of the I/O Map from 512 to 256, a decrease of
256 words. The Available Logic Area will automatically increase from 1198 to 1454.
Example 2 Similarly, if you allocate some number of words to the Peer Cop expansion size,
you will reduce the Available Logic Area by the number of words allocated for Peer
Cop.
