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
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 E5CC Controllers
(1) We will run the No. 0 Controller.
Change the RUN/STOP parameter (
r-s
) in the operation level of the E5CC to RUN (
run
).
For a Controller with event inputs, the Event Input 2 Assignment parameter (
ev-2
) in the
initial setting level is set to RUN/STOP (
stop
), so the RUN/STOP parameter will not be dis-
played. Change the Event Input 2 Assignment parameter to NONE (
none
), and then
change the RUN/STOP parameter to RUN.
(2) We will switch the No. 0 Controller to STOP.
Change the display format to
Hexadecimal 16 bit
on the Batch Monitor Dialog Box. Then,
confirm that DM15 (Request Flag) is 1 (Enable Writing), double-click DM16 (Operation
Command Code), enter 0101 hex (Stop), and press the Enter Key.
DM16 will change to 0, DM0 (Response Flag) will remain at 1 (Enable Writing), and “STOP”
will be displayed on the No. 0 Controller.
Confirm this for the No. 1 and No. 2 Controllers as well.
