Changing E5CD Settings
(1) We will check the area that is used to change E5CD set values.
The area that is used to change the set value is called the download area.
DM15 to DM29 is the download area for the No. 0 Controller (E5CD), DM45 to DM59 is the
download area for the No. 1 Controller, and DM75 to DM89 is the download area for the
No. 2 Controller.
With the default settings, the following parameters are set for the download areas.

(2) We will initialize the download areas with the set values from the E5CD Controllers.
The download areas have not been initialized, so we will initialize them with the set values
from the E5CD Controllers.
Double-click DM15 (Request Flag) on the Batch Monitor Dialog Box, enter 2 (Initialize
Download Areas), and press the Enter Key.
(3) We will confirm that the download areas have been initialized.
When initialization is completed, DM0 (Response Flag) will change to 1 (Normal End) and
DM15 (Request Flag) will automatically change to 1 (Enable Writing). Check the download
area to see if it has been initialized to the values given in the above table.
Confirm this for the No. 1 and No. 2 Controllers as well.
(4) We will change the set point for the No. 0 Controller.
Double-click DM17 (Set Point) on the Batch Monitor Dialog Box, enter 100 (64 hex) as the
value, and press the Enter Key. Confirm that DM0 (Request Flag) remains at 1 (Enable
Writing) and that the SV Display on the No. 0 Controller changes to 100.
Confirm this for the No. 1 and No. 2 Controllers as well.
Stopping the E5CD Controllers
(1) We will run the No. 0 Controller.
Change the RUN/STOP parameter (r-s) in the operation level of the E5CD to RUN (run).
