Siemens 6ES7516-3AN01-0AB0 SIMATIC S7-1500 CPU 1516-3 PN/DP
01Technical Summary
Siemens 6ES7516-3AN01-0AB0 is a SIMATIC S7-1500 CPU 1516-3 PN/DP central processing unit with 1 MB program work memory and 5 MB data work memory. Its integrated communications comprise a PROFINET IRT interface with a two-port switch, a second PROFINET RT interface and a PROFIBUS interface. The CPU requires a SIMATIC Memory Card and is identified by Siemens as a cancelled spare-part article, so both the installed hardware generation and the officially named successor must be reviewed before a change is approved.

03Features
Key Functions
- Executes S7-1500 control logic with a typical bit-operation time of 10 ns.
- Separates program and data work memory into 1 MB and 5 MB capacities.
- Provides deterministic PROFINET IRT connectivity through an integrated two-port switch.
- Adds a second PROFINET RT interface for another Ethernet communication path.
- Includes an integrated PROFIBUS interface for established distributed automation networks.
- Supports I&M data, configuration control by data set and isochronous operation in supported configurations.
Identification
- Manufacturer: Siemens
- Model: 6ES7516-3AN01-0AB0
- Product Type: SIMATIC S7-1500 CPU 1516-3 PN/DP central processing unit
- Status: Spare part; cancelled product
04Compatibility
- Confirm the complete article number and hardware functional status before exchanging an installed CPU.
- A SIMATIC Memory Card is mandatory; transfer the project only after verifying card capacity, firmware and protection settings.
- Match the existing PROFINET IRT topology, device names, IP configuration, update times and the second PROFINET network.
- Verify PROFIBUS address, baud rate, bus termination, device configuration and diagnostic organization.
- TIA Portal support depends on the installed firmware; Siemens lists V17 for firmware V2.9 and earlier integration paths for older firmware.
- Preserve the hardware configuration, user program, technology objects, communication relationships and retentive-data plan before replacement.
05Replacement
- Siemens identifies this article as a cancelled spare-part product with cancellation effective 2 June 2020.
- Siemens names 6ES7516-3AP03-0AB0 as the successor product; it is not a drop-in assumption because memory, performance and firmware differ.
- Compare work memory, CPU performance, interface behavior, firmware, TIA Portal version and all approvals before migration.
- Back up the project and record device names, IP parameters, PROFIBUS settings, certificates, passwords and Memory Card details.
- After installation, commission every communication path, distributed I/O station, safety-independent interlock and process sequence under controlled conditions.
