Product overview
2.1 Applications of the S7-1500 CPUs
Other technology functions
Technology modules also implement functions such as high-speed counting, position
detection, measuring functions and pulse generators (PTO, PWM and frequency output). For
compact CPU 1511C-1 PN and CPU 1512C-1 PN CPUs, these functions are already
integrated and can be implemented without additional technology modules.
SIWAREX is a versatile and flexible weighing module which you can use as a static scale for
operation.
Security Integrated
In conjunction with STEP 7 (TIA Portal), each CPU offers password-based know-how
protection against unauthorized reading out or modification of the program blocks.
The copy protection provides reliable protection against unauthorized reproduction of
program blocks. With copy protection, individual blocks on the SIMATIC memory card are
linked to its serial number so that 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 rights to various user groups.
Improved manipulation protection allows the CPUs to detect changed or unauthorized
transfers of the engineering data.
The use of an Ethernet CP (CP 1543-1) provides the user with additional access protection
by means of a firewall and/or the option of secured VPN connections.
Safety Integrated
The fail-safe CPUs are intended for users who want to implement demanding standard and
fail-safe applications both centrally and distributed.
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. The integration
also provides the system advantages and the extensive functionality of SIMATIC 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.
