4.9 Solutions for the engineering station
Engineering station
The engineering station (ES) serves as a central configuration station.
There are no redundant engineering stations in PCS 7.
The ES is generally used to make changes to the configuration data of project components
such as AS, OS and BATCH and then download the changes to the target systems. This makes
PCS 7 configuration centralized and transparent.
Configuration
In order to use an ES as an OS client, you need to configure a PC station in the PCS 7 project
for the ES. This PC station is configured and downloaded the same way as an operator station
with regard to hardware (Station Configuration Editor), networks and connections (NetPro).
The ES is displayed in NetPro.
If you specify permanently configured connections under "Named Connections", the following
rules apply:
● When configuring the connections for the ES, you must configure a connection for every
AS. This will ensure that a connection can be established to every AS regardless of which
WinCC project is loaded.
● For connections from the individual PC stations (OS servers and ES) to the automation
systems, the following rules apply:
– All connections within an AS must have the same name.
– Two connections must be configured for each OS server and the ES, one in AS 1 and
one in AS 2.
– The connections to AS 1 and the connections to AS 2 must always have the same name.
Backing up configuration data
The configuration data should always be backed up following a change in the configuration.
