SIMATIC S7-300 is the mini PLC system for the lower and medium performance ranges.
The modular and fan-free design, simple implementation of distributed structures, and convenient handling make the SIMATIC S7-300 the cost-effective and user-friendly solution for the most diverse tasks in the low-end and mid performance ranges.
S7-300 has different communication interfaces:
They are Communications processors for connecting to the bus systems AS-Interface, PROFIBUS and PROFINET/Industrial Ethernet. It has Communication modules for point-to-point connections. It has Multipoint interface (MPI), integrated into the CPU. It is the low-cost solution for simultaneous connection of PGs/PCs, HMI systems and other SIMATIC S7/C7 automation systems.
The SIMATIC S7-300 is connected to the PROFIBUS DP bus system via a communications module or via the CPUs with integral PROFIBUS DP interfaces. The CPUs with PROFIBUS DP master/slave interface enable distributed automation configurations with high speed and simple handling.
