The CPU 1511-1 PN is the cost-effective entry-level CPU for standard and fail-safe applications with medium requirements for processing speed and speed of response in discrete production technology. With its RAM size, this CPU is also suitable for medium-sized applications. 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 2-port switch so that a linear topology can be set up in the system. In addition, the CPU offers comprehensive control functionalities via easy-to-configure blocks as well as the ability to connect drives via standardized PLC-open blocks.

The CPU 1511F-1 PN has:

• a powerful processor: 
  The CPU achieves a command execution time as low as 60 ns per binary command.
• extensive RAM: 
  230 KB for program, 1 MB for data
• SIMATIC memory cards as load memory; 
  permit additional functions such as datalog and archives
• Flexible expansion possibilities: single-tier configuration with max. 32 modules (CPU + 31 modules)
• Display with functions for the
  • Display of overview information such as station name, higher level designation, location designation, etc.
  • Display of diagnostic information
  • Display of module information
  • Display of display settings
  • Setting of IP addresses
  • Setting of date and time
  • Selection of the operating mode
  • Resetting of the CPU to factory settings
  • Disabling/enabling of the display,
  • Enabling of protection levels
  • display of safety mode, overall signature and date of the last download with signature change.
• PROFINET IO IRT interface for connecting distributed I/O via PROFINET
• Supports PROFIsafe in centralized and distributed configuration

• 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
  • Powerful network connection:
    each CPU is equipped with PROFINET IO IRT (2-port switch) as standard interface.
• Integrated technology
  • Connection of analog and PROFIdrive-capable drives via standardized blocks (PLCopen)
  • Support of speed-controlled and positioning axes as well as external encoders
  • Trace functions for all CPU variables, both for diagnostics in real time as well as for sporadic error detection
  • Comprehensive 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 reading 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 into the CPU.
  • 4-level authorization concept: 
    Communication to the HMI devices can also be restricted.
  • Manipulation protection: 
    The controller recognizes changed or unauthorized transmissions of the engineering data.
• Design and handling
  • Display of the overview information:
    e.g. station name, plant identifier, 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.
• Integrated system diagnostics
  • System diagnostics information is displayed consistently and in plain text in the display, TIA Portal, HMI devices 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.
  • Additionally for storing additional documents or csv files (for recipes and archives)
  • Creation of data blocks for 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 a web server
  • Easy access to configuration data of the machine by means of a web browser or SD card reader (two-way data exchange from and to the controller)
• Programming of the standard program section
  • Programming with STEP 7 V12 SP1
• Programming of the fail-safe program section
  • Programming of the safety-related program section with the option package "STEP 7 Safety Advanced". STEP 7 Safety Advanced V12 can run under SIMATIC STEP 7 Professional V12 SP1.
