PCS 7 Web option

Requirements
The following requirements apply to using the Web solution:
● The Web solution can be implemented both in plants with a server/client structure as well
as on OS single stations.
● The Web solution gives users the opportunity to use a Web client to access Web servers
whose plants or plant areas still use a previous version of PCS 7 V8.2. You will find further
information on this in the FAQ "What should you watch out for when installing the PCS 7
Web Option with respect to Web Cross Connectivity?"
support.industry.siemens.com/cs/ww/en/view/92190315).
● In order to execute a process operation via faceplates, the OS hierarchy (Picture Tree)
must be derived from the SIMATIC Manager plant hierarchy. At the very minimum, however,
the area names used in the OS and AS must match.
OS server load
In the case of a plant where the configuration is planned as a mixture of OS clients and Web
clients, the permissible number of clients in terms of the load on the OS servers can be roughly
calculated using this formula:
Number of OS clients * 2 + number of Web clients * 1 <= 60
Notes on configuration
The following points must be taken into account when configuring the Web solution:
● Where there is an existing server/client structure, the number of times run through to publish
images, scripts and status displays for the Web server is based on the number of server
packages downloaded (publishing operations: number of server packages + Web server).
● The "WebNavigator" option must be enabled and selected as the startup screen
"@Screen.pd_" for the respective user in the User Administrator of the Web server.
● Different languages, which have been configured in the OS system, can be assigned in the
User Administrator for different logon profiles.
● It is also possible to emit an audible signal on a Web client when new messages occur.
You can find additional information on this in the configuration example "Audible Alarms
for PCS 7 Web Clients" (https://support.industry.siemens.com/cs/ww/en/view/29088810).
Note
You can find important information on the subject of performance improvement of clients and
systems, the Certification authority (CA), or Certificate Revocation List (CRL) in the contribution
