Features:
- Separate program and data work-memory areas keep executable code apart from live controller data.
- The first PROFINET path provides a two-port IRT switch, while the second Ethernet path has a separate communication role.
- A dedicated RS-485 channel supplies PROFIBUS DP master communication up to 12 Mbit/s.
The 6ES7516-3AN00-0AB0 performs the CPU 1516-3 PN/DP control role within a SIMATIC S7-1500 station.
A required SIMATIC Memory Card holds the load-memory content used with the integrated program and data work memory.
Local display, mode-selection, access-protection, and network-status functions support controller commissioning and operation.
The Siemens 6ES7516-3AN00-0AB0 SIMATIC S7-1500 CPU 1516-3 PN/DP Central Processing Unit may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).

Program, Data, and Load Storage
- Program area: Executable control code occupies the dedicated 1 MB work-memory partition.
- Data area: The separate 5 MB partition holds the working data used during execution.
- Load path: Project content is supplied through the required plug-in SIMATIC Memory Card.
- Runtime relation: The CPU transfers the required project content from removable load storage into its execution areas.
Separated Ethernet Functions
- First interface: Two switched RJ45 ports provide the PROFINET IRT connection.
- IO operation: This first path can operate as both PROFINET IO controller and IO device.
- Second interface: A single RJ45 port carries SIMATIC and open IE communication independently.
- Service access: Web-server communication is available on both documented Ethernet paths.
DP Master Communication Path
- Physical layer: The third communication interface uses an isolated RS-485 connection.
- Controller role: The channel is assigned to PROFIBUS DP master operation rather than DP-slave operation.
- Bus rate: The documented transmission ceiling is 12 Mbit/s.
- System relation: PROFIBUS devices remain on a dedicated fieldbus path instead of sharing the two Ethernet interfaces.
Project and Controller Access Controls
- User program: Password protection controls access to the loaded automation project.
- Program assets: Copy protection and block protection are supported for configured content.
- CPU access: Write, read/write, and complete protection levels can be selected.
- Local interface: The front display can be protected with its own password.
