1.2 PC Stations in SIMATIC
Use of PCs in Automation
A “PC station” is a PC with communication modules and software components
within an automation solution with SIMATIC.
The hardware configuration of a PC station can be compared with the configuration
of an S7 controller In SIMATIC:
In the same way, components of
a PC station, for example
modules, are assigned to a
virtual slot per software.
The virtual rack is implemented
on the PC station by software.
In an SIMATIC S7-400,
modules are inserted in the
slots in the rack.

applications. One typical software application with which user programs can
communicate is the SIMATIC NET OPC server.
