3.2 Introduction to PC-based control
Overview
The SIMATIC S7-1500 Software Controller is a PC-based controller and offers the same
functionality as all CPUs of the SIMATIC S7-1500 automation system in a PC-based real-
time environment.
As part of the SIMATIC series of products, the CPU can communicate with STEP 7 and
other SIMATIC products, such as WinCC, via Industrial Ethernet networks. You
communicate with the distributed I/O devices in the same way via PROFINET. The CPU
uses distributed I/O in order to control the automation process. You use the interfaces of
your PC to network the CPU with the distributed I/O. In addition, the CPU 1505SP can use
the centralized I/O of the ET 200SP Open Controller.
It uses PG/OP communication (Industrial Ethernet) for connection with STEP 7 or other
programming packages on a different PC.

You use the same programming languages, program structure, and programming interface
(STEP 7) to develop your user programs with the PC-based controller as for hardware
controllers. For the SIMATIC S7-1500 Software Controller, you can use the same user
program as for a hardware controller.
The CPU has a web server that can be run remotely from another PC. The web server
displays the operating status of the CPU. You can use the web server to perform diagnostics
and commissioning tasks.
