It is a universally accepted bus system that can network every area or unit level based on an international standard (Ethernet).
(2) PROFIBUS
It is a bus system suitable for the field of minicomputers and medium-sized computers. It is based on PROFIBUS, and PROFIBUS is consistent with EN50170 Volume2.
(3) AS-Interface
It is a network system of binary sensors and actuators used in the field of the smallest computer. SIMATIC is successfully integrated into the SIMATIC NET network landscape; it can be connected to PROFIBUS and Industrial Ethernet through its own inherent interfaces or communication modules.
(4) Multi-occupancy interface MPI
The successor of SINEC L1, MP realizes networking from simple to complex HMI systems, programming of devices/PCs and expansion of SIMATIC systems in a low-cost, high-efficiency way. In addition, powerful communication modules are also available for point-to-point connections.
(5) Point-to-point interface PPI
Available in the SIMATIC S7-200, this interface enables the user to communicate with many different nodes.
