Performance
Faster command processing, language extensions and new data types depending on the CPU type
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, precise position gearing between axes, cams/cam tracks and probes
Trace functions for all CPU tags, both for diagnostics in real time as well as for sporadic error detection; can also be called via the web server of the CPU
Comprehensive control functionalities, e.g. easy to configure 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 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 overview information:
E.g. Station name, plant identifier, location designation, etc., diagnostic information, module information, display settings.
Possible operations on the display:
Set addresses of the CPU or connected Ethernet communications processors, set date and time, select operating mode of CPU, reset CPU to factory settings, disable/enable display, activate protection levels, acknowledge messages, backup and restoring of the project.
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 a 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
Programming with STEP 7 Professional, V12 and higher
Migration tool for migrating from SIMATIC S7-300/S7-400 to S7-1500; converts the program code largely automatically. Non-convertible code is logged and can be manually adapted.
STEP 7 V11 projects can continue to be used with STEP 7 V12 in compatibility mode.
S7-1200 basic programs can be transferred to S7-1500 by copy-paste
