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 RT (2-port switch) as the standard interface.
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, 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 a plug-in load memory or for updating the firmware.
Also for storing additional documents or csv files (for recipes and archives)
