server will be active every time the device is turned on.
Activation by program
All of the program's AL alarm function blocks will be read before the web
server is started. At least one alarm function block must start the web
server – otherwise, it will remain deactivated.
The → "Web server startup behavior", page 718 table describes the vari-
ous possibilities regarding the web server's startup behavior.
CORS active
Only available on firmware version 2.00 or higher.
Only available on easySoft 8 or higher.
CORS (cross-origin resource sharing) makes it possible to access the
easyE4 base device's data from other websites.
One possible use case is using the JSON API to access the easyE4 base
device's data and then publish it on a selected website.
Parameter list enabled
If this option is enabled, the Parameter list menu option will be shown
in the web client catalog. In this case, it will be able to put together a
custom parameter list with operands in the web client. This will make
monitoring and controlling the relevant operands significantly easier.
Enable marker (write)
This is where the marker range for access through the web client is
enabled. The enabled range will apply to the administrator and to all
defined users equally.

Mode
If this option is enabled with a check mark, the relevant user will be able to
change the RUN/STOP operating mode for the easyE4 base device using
the web client's menu bar. The administrator definitely has the permission.
(the administrator always has the required permissions for this).
Clock
If this option is enabled with a check mark, the device time of the device
clock can be modified from the web client. This function may be helpful dur-
ing commissioning.
However, if in Project view/Clock the option
Synchronize clock via wireless (DCF77) is enabled, the device will get
its device time as a client from an SNTP server or from a wireless clock
(DCF77).
In the process, the time modified via the web client is overwritten again.
