What Is an Index?

An index is a numbered slot in the virtual rack of the PC station. The PC-based
controller occupies one index. The PC station contains other slots for the SIMATIC
components of a PC-based controller, such as those listed below:
•
CP card(s) (requires installation of SIMATIC NET)
•
SIMATIC HMI
•
SIMATIC NET OPC Server (requires installation of SIMATIC NET)
•
WinLC RTX
•
WinLC Basis
Each slot in the PC station corresponds to a number or index. When you install a
CPU 41x-2 PCI, the setup program configures the controller in the third index slot
by default. The Station Configuration Editor shows the configuration of your
PC station.
The index number for the CPU 41x-2 PCI must be between 2 and 18. However, the
index number in the Station Configuration Editor must be the same as the slot
number in the STEP 7 Hardware Configuration tool for the same component.
