10.13 Setting up a web server
Only possible with easySoft 8.
The web server is intended to make it even more convenient for users to use an
easyE4 control relay. This web server makes it possible to use a web client (i.e., a
web browser) to access the device as though it were being accessed directly on the
easyE4 base device. In other words, this means that the web service offers an addi-
tional interface for communication that is much like an additional HMI for the easyE4
device. In addition to this, the web client is also perfectly compatible with mobile
devices.
The device status can be ready directly on the display on EASY-E4-...-12...C1(P)
devices – please refer to → Section "Status display on control relay easyE4 with dis-
play and keypad", page 111.
EASY-E4-...-12...CX1(P) devices without a display can also be read using the web
server function.
The web server only has a limited amount of computing time available. This ensures
that easyE4 will not be negatively affected when it comes to running programs.
The web server needs to be configured in easySoft 8 by opening the Project view and
then going to the Web server tab.
10.13.1 Web server tab
For easySoft 8 and higher, the settings for web server communications are con-
figured under the Ethernet tab.
