Integrated technology functions
The CPUs of the SIMATIC S7-1500 family support Motion Control functions. STEP 7 offers
PLCopen standardized blocks for configuring and connecting a drive to the CPU. Motion
Control supports speed, positioning and synchronous axes, as well as external encoders.
For effective commissioning, diagnostics and fast optimization of drives and controls, the
SIMATIC S7-1500 controller family offers extensive trace functions for all CPU tags.
In addition to drive integration, the SIMATIC S7-1500 has extensive control functionalities,
such as easy-to-configure blocks for automatic optimization of the controller parameters for
optimized control quality.
Technology modules also implement functions such as high-speed counting, position
detection and measuring functions for 24 V signals up to 200 kHz.
Due to the integrated technology function, the CPUs are suitable, for example, for pumps,
fans, mixers, conveyor belts, lifting platforms, gate control systems, building management
systems, synchronized axes, cross cutters, etc.
Security Integrated
The CPUs are aimed at users that require the maximum possible plant security.
In combination with STEP 7, each CPU offers password-based know-how protection against
unauthorized reading or modifying of the program blocks.
The copy protection provides high-performance protection against unauthorized reproduction
of program blocks. The copy protection can be used to link individual blocks on the SIMATIC
memory card with their serial numbers. The block can only be executed if the configured
memory card is inserted in the CPU.
In addition, four different authorization levels in the CPUs can be used to assign different
access right to various user groups.
Improved manipulation protection allows the CPUs to detect changed or unauthorized
transfers of the engineering data.
Safety Integrated
The fail-safe CPUs are aimed at users that want to implement demanding standard and
fail-safe applications in both a centralized and a distributed manner.
These fail-safe CPUs allow the processing of standard and safety programs on a single
CPU. This allows fail-safe data to be evaluated in the standard user program. This
integration thus provides the system advantages and the extensive functionality of SIMATIC
also for fail-safe applications.
The fail-safe CPUs are certified for use in safety mode up to:
● Safety class (Safety Integrity Level) SIL 3 according to IEC 61508:2010
● Performance Level (PL) e and Category 4 according to ISO 13849-1:2006 or according to
EN ISO 13849-1:2008
Additional password protection for F-configuration and F-program is set up for IT security.
