Domain example
Changes can be made centrally, fast and conveniently in the domain structure. However, the
administration of a domain requires know-how, experience and additional work.
Workgroup example
In the workgroup, the majority of settings have to be made on the local computer. If a PCS 7
plant is running with fixed settings, however, and few changes are expected, these settings
only need to be made once. In this case, additional time for creating a domain and providing
extra training for the operating personnel is not required.
Integration in a domain
All PCs in the PCS 7 product bundles are configured for a Windows workgroup. If you include
preconfigured PC systems in a Windows domain, you must reactivate the security settings
using the SIMATIC "Security Controller" software.
DHCP server
Note
In PCS 7, the use of a DHCP server is only permitted with address reservation. All PC stations
must work with reserved addresses.
DNS / WINS server
The recommended solution for name resolution is the use of a DNS / WINS server.
