Differences Between Multiple Station Systems And Single Station Systems - Siemens PCS 7 Installation Manual

The difference between working with multiple PCs when engineering and working with a single
engineering station only involves a few steps.

3.4 Differences between multiple station systems and single station
systems
You can configure each PCS 7 application for process mode, for example OS, BATCH, RCS,
Maintenance Station, as a single station system or a multiple station system with client-server
architecture.
Definition of a multiple station system
A multiple station system is a system of related PCs in which the functionality of a PCS 7
application in a client-server architecture is distributed over several PCs, for example, OS
clients and OS servers. The Process Control System; SIMATIC PCS 7 DVD provides the
associated client or server software for this.
In the case of multiple station systems, we recommend that you configure a terminal bus
(separate from the system bus) for data communication between clients and servers.
Definition of a single station system
A single station system or "single station" is a PC that provides the entire functionality of a
PCS 7 application, for example the operator station. The Process Control System; SIMATIC
PCS 7 DVD provides the "single station" software for this.
You can connect single station systems to the system bus as well as to the terminal bus (for
example, when there are also multiple station systems in the PCS 7 plant).
