System overview
2.1 What is the SIMATIC S7-1500 automation system?
Field of application
The S7-1500 automation system offers the required flexibility and performance for a wide
range of controller applications in machine and plant engineering. The scalable configuration
makes it possible for you to adapt your PLC to the local conditions.
By using fail-safe S7-1500 CPUs and fail-safe modules, you can implement applications for
safety engineering. Configuration and programming of your safety program takes place the
same way as for standard CPUs - in the TIA Portal.
In addition to the standard motion control and technology functions available in the S7-1500,
SIMATIC S7-1500 technology CPUs offer you additional features such as enhanced
synchronous operation and cam disk functionalities.
The S7-1500 automation system is approved for IP20 degree of protection and is intended
for use in a dry environment and installation in a control cabinet.
Configuration
The SIMATIC S7-1500 automation system is made up of the following components:
● CPU (standard, fail-safe, compact or technology CPU)
● Digital and analog I/O modules
● Communications modules (PROFINET/Ethernet, PROFIBUS, point-to-point)
● Technology modules (counting, position detection, time-based IO)
● Load current supply
● System power supply (optional)
You install the S7-1500 automation system on a mounting rail. It can consist of up to 32
modules (CPU, system supply and 30 I/O modules). You connect the modules to each other
with U connectors.
