scroll, and the way the fields are being displayed will remain unchanged.

Web client cycle time
The web client's cycle time is the time between two requests for the device used to
update local data. In the following screen refresh cycle, the modified data is shown
in the web client (please note that the cycle time for the web client and the screen
refresh cycle time and independent from each other). The value range for the web cli-
ent's cycle time is 250 ms to 30000 ms, with the default value being 450 ms.
The web client's cycle time can be shortened if data needs to be shown in the web
client faster than the default value and the program is able to do this with its cycle
time.
Please note that reducing the web client's cycle time can
place an excessive load on the easyE4 device and block
device responses under certain circumstances.
