The SIMATIC S7-300 is a versatile solution that excels in driving innovation in manufacturing processes.
he SIMATIC S7-300 is highly suitable for deployment in various sectors such as plastics processing, packaging, food and beverage, as well as process engineering.
A hierarchical CPU family with an extremely wide performance range is available for configuring the controller.
The product range includes 7 standard CPUs,
7 compact CPUs, 5 fail-safe CPUs and 3 technology CPUs.
Existing CPUs are only 40mm wide
The SIMATIC S7-300 is part of our Totally Integrated Automation design and is the most sold controller.
Scope of applications
The S7-300 enables space-saving and modular configuration. In addition to the modules, only a DIN mounting rail is required to hold the modules and rotate them into place.
This results in a robust and EMC-compatible design.
The ready-to-use backplane bus can be expanded by simply plugging in additional modules and bus connectors. The extensive range of the S7-300 series can be used both for central expansion and for building distributed structures with ET 200M; thus enabling cost-effective spare parts control.
If the automation task requires more than 8 modules, the central controller (CC) of the S7-300 can be expanded using expansion units (EU). There can be a maximum of 32 modules on the center shelf, with a maximum of 8 on each expansion unit. An interface module (IM) can handle the communication between the various racks simultaneously. CC/EU can also be installed at long distances from each other (up to 10m) if the plant covers a wide area.
In a single-level structure, this enables a maximum configuration of 256 I/Os, and in a multi-level structure up to 1024 I/Os. In a distributed configuration with PROFIBUS DP, there can be 65536 I/O connections (up to 125 stations, eg ET200M via IM153). Slots are freely addressable, so slot rules are not required.
The wide variety of S7-300 modules can also be used in distributed automation solutions.
The ET 200M I/O system with the same structure as the S7-300 can be connected not only to PROFIBUS but also to PROFINET via interface modules.
