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:

• 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)
  • Support of speed-controlled and positioning axes as well as external encoders
  • Trace functions for all CPU tags, 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 in 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 overview information:
    e.g. station name, plant identifier, location ID, diagnostic information, module information, display settings, etc.
  • 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.
  • Also 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 V13
• Programming of the failsafe program section
  • Programming of the safety-related program section with the option package "STEP 7 Safety Advanced".
