E5AR/ER-DRT Operation Data and Setting Data
Monitor values and setting data with communications addresses that be-
long to the following variable types can be allocated. Duplicate settings are
possible and are processed in ascending order.
Note
If items are allocated in the read-only area of the OUT Area, words
are allocated in memory but operate as if they had not been allo-
cated.

Output Enable Bits
Output Enable Bits are allocated in the first word of the OUT Area.
When Output Enable Bits are allocated in the IN Area, they are always set
to 0 (OFF).
Note
If data allocated to the IN or OUT Area is changed, use a software reset or
cycle the power to enable the new settings.
