 Siemens SIMATIC S7 controllers range from compact, entry-level units to high-performance modular systems designed for complex industrial automation. The S7-1200 and S7-1500 represent the current generation optimized for the TIA Portal, while the S7-300 and S7-400 are legacy modular systems. Siemens SIMATIC S7 controllers range from compact, entry-level units to high-performance modular systems designed for complex industrial automation.
