Web diagnostics
11.1 Requirements
Configuring and commissioning S7 CPs for Industrial Ethernet
168 Configuration Manual, 09/2013, C79000-G8976-C182-13
Note
Station or device names configured in STEP
7 with special characters (for example umlauts
ä, ü etc.) may not be correctly interpreted in Web diagnostic
s.
Settings for access to diagnostics data
Check the following settings that are necessary for access to the diagnostics data:
● To load diagnostics data, JavaScript must be enabled in the Internet browser.
● The browser must support frames.
● Cookies must be accepted.
● The browser should be set so that it downloads the current data from the server
automatically each time it accesses a page.
In Internet Explorer, you will find these settings in the "Tools" menu > "Internet Options" >
"General" tab > "Temporary Internet Files" > "Settings" button.
● When using a firewall on your PG/PC, the following port must be enabled for Web
diagnostics: "http port 80/TCP"
● Activating Web server functionality
The Web server functionality must be activated in the STEP 7 configuration: refer to
Configuring the Ethernet CP with STEP 7 (Page 39)
As default, the Web server is activated and therefore port 80 of the CP is opened for
HTTP access.
If you want to block port 80, disable the "Activate Web server function" option. This option
is not available in STEP 7 for all CPs.
Security activated - different settings for access to diagnostics data
In addition to or in contrast to the settings listed above, the following requirements must be
kept in mind if security is enabled:
● When using a firewall on your PG/PC, the following port must be enabled for Web
diagnostics: "https port 443/TCP"
● Activating Web server functionality
The Web server functionality must be activated in the STEP 7 configuration.
As default, the "Allow access only via HTTPS" option is enabled and port 443 is therefore
opened for HTTPS.
If you want to block port 443 of the CP, disable the "Allow access only via HTTPS" option.
● Current time-of-day and date on the S7 station
The CP needs to access the current date and current time-of-day. Otherwise, there will
be conflicts in the certificate checks and no Web access will be possible.
