3.6 Solutions for multiple station systems
3.6.1 Operator station multiple station system
Operator station as multiple station system with client-server architecture
● The OS multiple station system consists of OS clients (workstations), which are supplied
with data (project data, process values, archives, alarms, and messages) from an OS server
or multiple OS servers via a terminal bus (OS LAN).
● The OS servers feature additional client functions that allow them to access data on other
OS servers (their archives, messages, tags and variables). Process pictures from an OS
server can then also contain tags of other OS servers.
● You can achieve high availability for the Operator Station by configuring a redundant OS
server. You also need the "SIMATIC PCS 7 Server Redundancy" software package for
redundant OS servers.
For smaller plants, system configurations with multiple OS single station systems is
appropriate. You can find information about this in section "OS single station system
(Page 29)".
