Siemens 6ES7516-3AN02-0AB0 SIMATIC S7-1500 CPU 1516-3 PN/DP With Work Memory 1MB

Overview
Part Number: 6ES7516-3AN02-0AB0
The Siemens S7-1500 CPU 1516-3 PN/DP is a mid-range to high-end PLC powerhouse engineered for fast, deterministic control of large I/O counts, motion axes and integrated safety. It features three onboard communication interfaces—two Gigabit Ethernet ports (PROFINET IRT, RT, TCP/IP, OPC UA server) and one PROFIBUS DP master—making it ideal for hybrid factory-automation and process applications.

Key Specifications
• Work memory: 1 MB for program + 5 MB for data
• Load memory: Up to 32 GB SIMATIC Memory Card (SMC) support
• Processing time: 10 ns / bit operation, 64 ns / word operation
• I/O capacity: Up to 32 768 DI/DO or 2 048 AI/AO per CPU
• Integrated motion: 128 axes via PROFINET IRT or PROFIBUS DP (without additional hardware)
• Web server, user-defined webpages, e-mail & FTP for IIoT connectivity
• Security built-in: Know-how protection, integrity protection, encrypted communication (TLS 1.3)
• Redundant power supply support via optional system power module

Hardware Features
• Compact single-slot width (35 mm) – saves panel space
• Built-in display with 6-line plain-text diagnostics and IP address setting
• High-speed counters (100 kHz) and PTO/PWM for stepper/servo drives
• Retentive data without battery thanks to SMC backup
• Operating temperature –25 °C … +60 °C, conformal-coated boards available

Typical Applications
• Modular packaging machines with vision & robotics
• High-speed bottling & labeling lines
• Process skids with integrated safety & energy monitoring
• Material handling AS/RS systems
• Centralized or distributed motion control solutions
