Note:
SIMATIC Memory Card required for operation of the CPU
Application
The CPU 1516F-3 PN/DP is the CPU with a large program and data memory for demanding standard and fail-safe applications that also contain distributed automation structures alongside central I/O.
It can be used as a PROFINET IO controller or as distributed intelligence (PROFINET I-Device). The integrated PROFINET IO IRT interface is designed as a 2-port switch, enabling a linear topology to be set up in the system. The additional integrated PROFINET interface with separate IP address can be used, for example, for network separation. Distributed I/O can be connected via PROFIBUS (or PROFIsafe) via the integrated PROFIBUS interface. In addition, the CPU offers comprehensive control functionalities as well as the ability to connect drives via standardized PLCopen blocks.
Design
The CPU 1516F-3 PN/DP has:
- A powerful processor:
The CPU achieves a command execution time as low as 6 ns per binary command. - Extensive work memory:
3 MB for program, 7.5 MB for data - SIMATIC Memory Cards as load memory;
permit additional functions such as datalog and archives - Flexible expansion capability:
single-tier configuration with max. 32 modules (CPU + 31 modules) - Display with functions for:
- Display of overview information such as IP address of the integrated interface, device name, plant designation, location designation, etc.

- Supports PROFIsafe in centralized and distributed configuration
Function
Thanks to a variety of innovations and integrated functions, the SIMATIC S7-1500 CPUs offer added value with regard to performance and engineering efficiency. A host of features support users in programming, commissioning, and servicing the S7-1500 controller:
- Performance
- Faster command processing, depending on the CPU type, language extensions and new data types
- Even shorter response times of the CPUs due to considerably faster backplane bus
- High-performance network connection:
PROFINET IO IRT (2-port switch) as standard interface. Additional PROFINET interface integrated, e.g. for network separation.
- Integrated technology
- Connection of analog and PROFIdrive-capable drives via standardized blocks (PLCopen)
- Integrated Motion Control functionalities for controlling speed-controlled, positioning and synchronized axes (gearing), support for external encoders, output cams/cam tracks and probes
- Trace functions for all CPU tags, both for diagnostics in real time as well as for sporadic error detection
- Extensive control functionalities, e.g. easily configurable blocks for automatic optimization of the control parameters for optimum control quality
- Security Integrated
- Password-based know-how protection against unauthorized read-out and modification of program blocks
- Copy protection for tying individual blocks to the serial number of the SIMATIC Memory Card:
The block can only run if the configured memory card is inserted in the CPU.
4-stage authorization concept:
Communication to operator panels can also be restricted. - Manipulation protection:
The controller recognizes changed or unauthorized transmissions of the engineering data.
- Design and handling
- Display of overview information:
e.g. station name, plant designation, location designation, etc., diagnostic information, module information, display settings - Possible operations on the display:
set addresses, set date and time, select operating mode of CPU, reset CPU to factory settings, disable/enable display, activate protection levels.
- Display of overview information:
- Integrated system diagnostics
- System diagnostics information is displayed consistently and in plain text in the display, TIA Portal, operator panels and web server, even for messages from the drives, and updated even if the CPU is in STOP mode.
- Integrated in the firmware of the CPU, no special configuration is required
- SIMATIC Memory Card (required for operation of the CPU)
- Used as plug-in load memory or for updating the firmware.
- Also for storing additional documents or csv files (for recipes and archives)
- Creation of data blocks and storage/reading of data via SFCs of the user program
- Datalog (archives) and recipes
- Storage of csv files for recipes and archives on the SIMATIC Memory Card;
easy access to plant-relevant operating data using Office tools or via web server - Easy access to machine configuration data by means of a Web browser or SD card reader (two-way data exchange from and to the controller)
- Storage of csv files for recipes and archives on the SIMATIC Memory Card;
- Programming of the standard program section
- Programming with STEP 7 V13
- Programming of the fail-safe program section
- Programming of the safety-related program section with the “STEP 7 Safety Advanced” option package.
