Scenarios (examples)
Domain (AD; Active Directory)
Workgroup (WG)
Devices are added (e.g.
printer, fax or scanner).
The devices are announced by AD.
Devices not announced.
The information for connecting to the device
must be known.
The security settings can be made centrally for
each device.
Each user that uses the device must be created
locally at this PC station and log on with local
user information.
One user uses multiple
computers.
The user profile can be saved centrally.
This applies the settings to all PC stations at
logon.
The user has a local profile on each PC station.
If the profile is not saved centrally, every user
will have their own local profile.
The lists above are not weighted in terms of importance; you must determine which advantage
or disadvantage is the most significant for the PCS 7 plant in question.
Setting package size for communication (MTU size)
As of PCS 7 V8.1 SP1, the MTU (maximum transmission unit) size must be set for all computers
located in the PCS 7 plant.
● Setup makes the necessary settings on computers with installed PCS 7 components.
● The MTU size has to be set to 1494 bytes for all components without a PCS 7 installation.
This can be done on computers without a PCS 7 installation (e.g. domain controller and
file server) or network components based on Windows (e.g. Automation Firewall) using the
tool "set_mtu_size_to_1494.exe".
– You can find the "set_mtu_size_to_1494.exe" tool on the PCS 7 DVD 2 in the folder
Additional_Products > MTU.
Documentation on the tool can be found in the same folder.
– An administrator must execute this file on all computers on which no PCS 7 components
are installed.
