7.8 Setting areas
The E5AR/ER has two setting areas for communication functions:
Setting area 0 and setting area 1.
In setting area 0, control continues.
As such, setting area 0 makes it possible to perform operations that
require control to be in progress, such as reading the PV, writing an
SP, and run/stop, as well as operations that do not interfere with
control. On the other hand, operations that may change control such
as writing initial setting data cannot be performed. (Note that setting
data that cannot be written can still be read.)
In setting area 1, control is stopped.
This makes it possible to perform operations such as writing initial
setting data which are not possible in setting area 0.
When the power is turned on, setting area 0 is selected. To access
setting area 1, use the "Move to setting area 1" operation command.
To return to setting area 0 from setting area 1, turn off the power or
use the "Software reset" operation command.
