System overview
4.1 Overview of the SIMATIC S7-1500 automation system
4.1.1 The SIMATIC automation systems
You need optimum solutions for every application in order to automate your machines and
plants economically and flexibly.
The SIMATIC controller portfolio includes a variety of systems:
• The SIMATIC S7-1200 Basic Controller is the intelligent choice for compact automation
solutions with integrated communication and technology functions.
• If plant complexity and system performance are priorities, the SIMATIC S7-1500
automation system is the right choice for you. The SIMATIC S7-1500 controller builds on
the more simple functionality of the SIMATIC S7-1200 Basic Controller and fulfills the
highest demands on performance, flexibility and networking capability.
• The SIMATIC ET 200SP Distributed Controller combines the advantages of the S7-1500 and
the very compact design of the ET 200SP with high channel density. By using distributed
intelligence, you save costs and space in the control cabinet.
• For use outside the cabinet, the CPU 1513pro-2 PN and CPU 1516pro-2 PN offer you
SIMATIC S7-1500 functionality in the design of the ET 200pro in the degree of protection
IP65/IP67.
• If you require PC-based automation, use the SIMATIC S7-1500 software controller. The PC-
based controller is autonomous from the operating system during operation.
• If you want to increase the availability of your system, use the redundant system S7-
1500R/H. In the system, two CPUs (primary and backup CPU) process the user program in
parallel and permanently synchronize all relevant data. In the event of failure of the
primary CPU, the backup CPU takes over control of the process at the point of interruption.
