Rules
Only use the PC configurations described here within a PCS 7 project.
Several program packages may be installed on a PC station. However, these
stations may only be used simultaneously in exceptional cases (see the con‐
figuration tables below).
Activating several program packages will impair the performance of the indi‐
vidual applications.
More powerful equipment may be required for the PC configurations descri‐
bed here (for example, larger work memory, operating system).
You can find information about the minimum performance requirements of the
individual standard configurations in the catalog
You can activate the properties of several standard configurations on a PC
station if:
● Other program packages have been installed in addition to the standard
configuration (for example, BATCH client on engineering station) or
● You activate special properties of the standard configuration
(for example, OS workstation on OS server).
If you use a server as a workstation also, you can connect a maximum of five
workstations (monitors) to that server (workstation on server + workstations
on assigned clients).
The maintenance station can be configured as a single station or multiple
station system. You can configure the MS server with PCS 7 servers on a
PC‑station in accordance with Table 2 below. The engineering station or an
OS client can be used as MS‑client.
The Information Server can be installed on a Process
formation Server) Historian.
Information Server
OpenPCS 7 can be installed on the following PC stations:
● Separate PC station
● OS client
● OS server
● OS single station system
In the interests of maintaining performance levels, you must not use more
than two server applications on a PC station.
If several PCS 7 server applications are active in process mode on one server
of a pair (for example, BATCH server and Route Control server), we recom‐
mend the following:
Make sure that you always start or stop all of a server's PCS 7 server appli‐
cations. This will allow you to avoid faults should a redundant server fail.
Note: Should a PCS 7 server application on a PC of a PCS 7 server pair fail,
all PCS 7 applications for this PC's process mode will be terminated automat‐
ically.
