controller. The CPU can also be used as standalone device.
By using fail-safe CPUs, you can implement applications for safety engineering.
Configuration and programming of your safety program takes place the same way as for
standard CPUs.
A wide range of I/O modules rounds off the product range.
SIMATIC ET 200SP is designed with degree of protection IP20 and is intended for
installation in a control cabinet.
