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 E5CC Controllers.
The download areas have not been initialized, so we will initialize them with the set values
from the E5CC Controllers. Double-click D0015 (Request Flag) in the PLC Memory Win-
dow. The following dialog box is displayed. Enter 2 (Initialize Download Areas) and click the
OK Button.
(3) We will confirm that the download areas have been initialized.
When initialization is completed, D0000 (Response Flag) will change to 1 (Normal End) and
D0015 (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 D0017 (Set Point) in the PLC Memory Window, enter 100 (64 hex) for the
value, and then click the OK Button. Confirm that D0000 (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.
