7.8 Setting Areas

7-18
The E5AR-T/ER-T has two setting areas for communications: Setting
area 0 and setting area 1.
In setting area 0, operation continues. Setting area 0 makes it possible
to perform operations that require operation to be in progress, such as
reading the PV, writing an SP, and starting/resetting operation (Run/
Reset), as well as operations that do not interfere with control. On the
other hand, operations that may change control, such as writing Initial
set values, cannot be performed. (Set values that cannot be written
can still be read.)
In setting area 1, operation is stopped. This makes it possible to
perform operations such as writing Initial set values, which cannot be
written 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.
