Central Processing Units (CPU) control and regulate processes in plant and machinery. The CPUs are selected according to application with the appropriate performance and work memory and can be extended with signal and function modules, as well as communication processors.
The System 300S CPUs are designed command compatible to Siemens STEP7 and for medium and large applications.
The CPUs are based on the SPEED7 technology. Here, the CPU is supported by co-processors. The integrated SPEED7 ASIC system is among the world's fastest automation systems.
A wide range of CPU options makes the system universally deployable: From C-class CPUs with integrated I/O peripherals for smaller applications up to CPU versions with integrated Ethernet, fieldbus master interfaces, and high-speed bus.
The CPUs of System 300S make possible short machine cycle times due to their high processing speed, and are therefore particularly suitable for complex control and automation tasks in the manufacturing and process industries. The compact CPUs with integrated I/Os are designed especially for cost-sensitive applications.
