High Processing Performance:Equipped with a powerful CPU enabling fast instruction execution (as low as 0.1 μs for bit operations), ideal for complex logic and high-speed control applications.
Large Memory Capacity & Expandability:
Up to 512 KB of working RAM for handling large programs and extensive data processing.Load memory can be expanded via SIMATIC Memory Cards (e.g., 64 KB or higher), supporting easy program backup and updates.Integrated MPI/DP Communication Interface:
Built-in MPI (Multi-Point Interface) and PROFIBUS DP Master interface for high-speed communication with HMIs, SCADA systems, and distributed I/O (e.g., ET200 stations).Supports up to 32 nodes on the MPI network, offering flexible networking options.PROFIBUS-DP Fieldbus Support:Operates as a DP master to connect remote I/O modules (e.g., IM153), enabling distributed automation architectures—perfect for large-scale plant control systems.
High I/O Expansion Capability:
Supports up to 32 expansion modules via IM360/361 or distributed I/O setups.Fully compatible with the entire S7-300 module family (digital/analog I/O, function modules, communication processors).
