System composition

Central Processing Unit (CPU)
Various CPUs have different performances. For example, some CPUs are integrated with input/output points, and some CPUs are integrated with PROFIBUS-DP communication interfaces.
Signal Module (SM)
For digital and analog input/output
Communication Processor (CP)
Used to connect to the network and point-to-point connection
Functional Module (FM)
Used for high-speed counting, positioning operation (open-loop or closed-loop positioning), and closed-loop control.
Load Power Supply Module (PS)
Used to connect SIMATIC S7-300 to 120/230 volt AC power supply, or 24/48/60/110 volt DC power supply.
Interface Module (IM)
Connect the main rack (CR) and expansion rack (ER) when used in a multi-rack configuration. The S7-300 can operate up to 32 modules through a distributed mainframe (CR) and 3 expansion frames (ER). No fan is required during operation.

SIMATIC S7-300 is suitable for the general field

High electromagnetic compatibility and strong anti-vibration and shock resistance, making it have the highest industrial environment adaptability.
