Innovative real-time system based on visualization technology: The real-time system of the integrated S7-1500 software controllers enables parallel, independent operation of Windows:
Maximum real-time and deterministic properties
Supports restart of Windows while the controller is in operation
High-speed program execution with several priority-controlled execution levels (cyclic, time-controlled, isochronous with PROFINET or PROFIBUS, event-driven via process and diagnostics alarms)
Saving of retentive data: The CPU 1515SP PC ensures the security of plant data even when the power fails:
Saving of retentive data on the NVRAM of the CPU possible during voltage dips
Retentive data storage possible on CPU CFast card (UPS required)
Communication:
PROFINET IO communication via the ET 200SP BusAdapter; PROFIBUS communication via ET 200SP CM DP: PROFINET IO RT/IRT, isochronous mode, IO controller, I-Device, media redundancy, PROFIenergy, PROFIBUS DP master
SIMATIC and Open User communication with Windows applications or external devices via the Windows interfaces (GB Ethernet) of the CPU
Configuration control (option handling) for flexible variations of the central configuration
Configure a controller and operate variants (options) that differ from this configuration
Integrated Web server: Scanning the CPU via the Web server is supported by all CPUs of the S7?1500 automation system. The CPU Web server offers the following diagnostics options:
Image of the CPU with LEDs and the current operating state
Readout of the diagnostics buffer entries
Query of module status
Query of current messages
Information on the status of the topology/PROFINET devices
Transfer and management of user data on load memory of the CPU
User-programmable Web pages for supporting servicing and commissioning of specific machine functions
Trace functionality: The trace function is supported by all CPUs of the S7-1500 automation system. It enables recording of analog and digital variables for each cycle and their representation as a curve with STEP 7. This is especially useful for Motion Control or closed-loop control applications
Integrated technology:
S7-1500 Motion Control PLCopen blocks for programming the motion functionality via PROFINET IO IRT interface. The functionality supports speed-controlled axes, positioning axes and external encoders.
Integral closed-loop control functionality: Universal PID or 3-step controller with integrated optimization. Integrated temperature controller.
Integrated system diagnostics: System diagnostics can be displayed via a connected monitor, an HMI device, the Web server, or the operator panel of the software controller. Drive messages are also displayed in this way. System diagnostics are also available when the CPU is in STOP mode. If new hardware components are configured, the diagnostic information is updated automatically.
Integrated safety:
Know-how protection: Algorithms and program blocks can be reliably password-protected against unauthorized access and modification.
Access protection: Extended access protection provides comprehensive protection against unauthorized configuration changes. Various authorization levels are available for assigning separate rights to different user groups.
Integrity protection: The system protects the data transferred to the CPU against unauthorized tampering. Modified or third-party transmission of engineering data are safely detected by the CPU.
