Note
You need to separately order the license keys for the optional add-on product bundles (such
as SIMATIC PDM).
Operating principle
The external engineering station is networked with the SIMATIC PCS 7 BOX station. The
SIMATIC PCS 7 BOX PC is connected to the external engineering station via one of the two
on-board Ethernet interfaces. You use this connection to load the SIMATIC PCS 7 BOX station
(AS and OS). You can use the "Download Changes of OS" function in this configuration.
Properties of SIMATIC PCS 7 BOX RTX
The time synchronization of the OS and the CPU in this configuration is performed using WinAC
time synchronization with the local PC clock only, if no externally connected clock is included.
Interface properties
You can find information about this in the following sections:
● Section "Connection to PROFIBUS DP (Page 41)"
● Section "Network connection to Industrial Ethernet (Page 42)"

In this configuration, you integrate the SIMATIC PCS 7 BOX station in a PCS 7 network as a
PC station with OS/AS. Here, in contrast to the "SIMATIC PCS 7 BOX with external
engineering (Page 36)" configuration, you need two network connections – from the SIMATIC
PCS 7 BOX station to the terminal bus and to the plant bus. In this configuration, you can
synchronize the time of day of the CPU using a time master connected to the plant bus.
