• Program Memory: 15 MB

• Load Memory: Typically loaded via MMC (MultiMediaCard) or other supported storage media, depending on system configuration

• Retentive Memory: Available for retaining data blocks across power cycles

Programming Environment

• Supported Software: STEP 7 V5.5 + SP1 or higher (recommended for best compatibility and features)

Processing Capabilities

• Processing performance tailored for complex automation tasks and high-speed operations

• Detailed operation times (e.g., bit, word, fixed-point, and floating-point arithmetic) should be consulted in the official documentation, as they can vary based on specific CPU model and configuration

Additional Features

• Program Block Quantities:

• Maximum number of Data Blocks (DBs): Dependent on memory allocation, but designed for large-scale applications

• Maximum number of Function Blocks (FBs) and Functions (FCs): Dependent on memory allocation, allowing for modular and reusable code

• Types and quantities of Organization Blocks (OBs): Comprehensive set including OB1 (main cycle), OBs for interrupts, errors, and system events, and others tailored for high-availability operations

• Counters and Timers:

• S7 Counters: Unlimited (limited only by RAM capacity), with retentivity for critical applications

• S7 Timers: Unlimited (limited only by RAM capacity), with retentivity to maintain timing across power cycles or failures

• High-availability features:

• Automatic CPU synchronization

• Failover and failback mechanisms

• Integrated diagnostic and error reporting
