Structure of SIMATIC PCS 7 BOX 
  Process Control System PCS 7 - PCS 7 BOX 
3-8  A5E00272813-01 
Mode of Operation 
The station (Box PC 620 with integrated AS in the form of a CPU 416-2 PCI) is not 
networked from the viewpoint of the PCS 7 project. You create and edit your PCS 7 
project on this station and download the PCS 7 project from the ES to the OS and 
CPU 416-2 PCI. The program created with SIMATIC PCS 7 operates in runtime on 
the OS/WinCC and CPU 416-2 PCI.  
You can use the Process Device Manager to access the PROFIBUS line and its 
stations/devices via the special on-board CP5611 interface. In the SIMATIC 
Manager, you can access the integrated CPU 416-2 PCI via the PCI interface just 
like in standard SIMATIC PCS 7. 
 
 
Note 
For more information, read the note in the Chapter "Special Features about the 
CPU 416-2 PCI Interfaces". 
 
Changes can be made in runtime as usual with PCS 7. 
There are no restrictions for the PCS 7 programs that can be created. 
Restrictions 
The following functions are not possible with the SIMATIC PCS 7 BOX as a single 
station system: 
•  The time synchronization between the OS/WinCC and CPU 416-2 PCI can 
only be implemented in this configuration variant using the WinAC time 
synchronization from the PC clock since no external clock can be connected. 
•  The PROFIBUS DP/MPI interface of the CPU 416-2 PCI is fully functional but 
the capacity of the PROFIBUS DP/MPI interface is limited. It is recommended 
to only connected I/O stations that do not require PDM operation to this 
interface. 
•  Plant changes during ongoing operation using CiR (Configuration in Run) 
cannot be performed. 
•  Configuration changes to the OS cannot be downloaded online.
