Web server for easy Internet connectivity
9
The Web server provides Web page access to data about your CPU and to the process data
within the CPU. With these Web pages, you access the CPU with the Web browser of your
PC or mobile device. The standard web pages allow authorized users to perform a variety of
functions:
● You can change the operating mode (STOP and RUN) of the CPU.
● You can monitor and modify the status of the PLC tags.
● You can view and download any data logs being collected by the CPU.
● You can view the diagnostic buffer of the CPU.
● You can update the firmware of the CPU.
The Web server also allows you to create user-defined Web pages that can access CPU
data. You can develop these pages with the HTML authoring software of your choice. You
insert pre-defined "AWP" (Automation Web Programming) commands in your HTML code to
access the data in the CPU.
You set up users and privilege levels for the Web server in the device configuration for the
CPU in STEP 7.
