SINUMERIK Safety Integrated

SINUMERIK Safety Integrated provides integrated safety functions that support the implementation of highly effective personnel and machine protection. These safety functions meet the requirements of EN 61508 for use up to and including SIL2 and Category 3, as well as PL d according to EN ISO 13849. This allows not only for simple and economic implementation of the main requirements for functional safety, but also the realization of practical operating and security concepts.

Available functions include, among others:

• Functions for safety monitoring of velocity and standstill
• Functions for establishing safe boundaries in work spaces and protected spaces, and for range recognition
• Direct connection of all safety-related signals and their internal logical linking
• Safe Brake Management
• Safe communication via PROFIBUS or PROFINET
• Operator-controlled acceptance test – integrated in SINUMERIK Operate

• High level of safety:
  Complete implementation of the safety functions in Category 3/SIL 2/PL d
• High level of flexibility:
  Practical safety and operating concepts can be implemented
• Extremely cost-effective:
  Reduced hardware and installation costs
• Enhanced availability:
  Absence of interference-susceptible electromechanical switching elements

SINUMERIK Safety Integrated

The safety functions are available in all modes and can communicate with the process using safety-oriented input/output signals. They can be implemented for each individual axis and spindle.

Safety Integrated drive-based (basic version):

• Safe Torque Off (STO)
  Suppression of drive pulses, providing safe electronic interruption of the energy supply
• Safe Brake Control (SBC)
  Safe, 2-channel control of a holding brake – integrated in the SINAMICS S120 Motor Module
• Safe Stop 1 (SS1) time-controlled
  Safe shutdown of a drive, with subsequent transition into the STO state

The Safety Integrated basic functions are license-free.

Requirements:

• SINUMERIK 840D sl
• SINAMICS S120 Booksize format
• The encoder systems used must meet the requirements of SINUMERIK Safety Integrated.
• The measuring circuit cables must comply with the specifications of SINAMICS S120.
• Sensor/actuator integration with PROFIsafe I/Os
• Fail-safe modules (PROFINET IO/PROFIBUS DP):
  • SIMATIC S7‑300 signal modules in ET 200M
  • SIMATIC ET 200MP
  • SIMATIC ET 200SP
  • SIMATIC ET 200S
  • SIMATIC ET 200pro
  • SIMATIC ET 200iSP
  • SIMATIC ET 200eco
• Fail-safe standard I/O or DP devices (light array, laser scanner, etc.)
• Extension of the configuration with standard I/O devices possible.
• SIMATIC S7 F Configuration Pack available as a download at:

• For the integrated acceptance test:
  • SinuCom software tool (can run on PC/PG)

Only one SI Basic and one SI Comfort option can be ordered for each SINUMERIK 840D sl. If a machine with Safety Integrated requires up to 4 safe inputs and 4 safe outputs, the SI Basic option can be ordered. If five or more safe inputs/outputs are required, the SI Comfort option should be ordered.

Ordering example 1:
The machine has 2 axes and 1 spindle which are to be monitored by Safety Integrated. 4 safe inputs and 3 safe outputs are required. The following options must be ordered:

Ordering example 2:
The machine has 5 axes and 1 spindle, which are to be monitored by Safety Integrated. 9 safe inputs and 5 safe outputs are required. The following options must be ordered:

The Safety Integrated functions of the SINUMERIK are generally certified by independent institutes. An up-to-date list of certified components is available on request from your local Siemens office or regional company. If you have any questions relating to certifications that have not been completed, please ask your Siemens contact.

Encoder systems

If you require information about the use of suitable encoder systems with SINUMERIK Safety Integrated, please contact your local Siemens office or regional company.
