Configuring Safety Integrated (SPL)

10.7.1

Introduction

With the aid of safe programmable logic (SPL), safety-related sensors and actuators can be
directly connected to the control's I/O and evaluated by means of software without external
evaluation units.
In order to check that the NCK SPL and PLC SPL are functioning, the system program
organizes a cyclic data cross-check between the PLC and the NCK.
Figure 10-10
The Safety Integrated (SPL) mode is supported by all NCU versions available in the TIA Portal.
The Safety Integrated (SPL) mode has the following characteristics:
● SINAMICS Integrated or connected NX use the SINUMERIK "SI Motion Monitoring"
telegrams, not the PROFIsafe telegrams.
● The user program is programmed like a standard user program in the editors for STL, FBD
or LAD. Each safety-related program must be created in two programming languages in
order to allow the data cross-check (PLC SPL and NCK SPL).
● During the programming, the SGE/SGA of the data block SPL [DB18] is used that you
assign on the NCU (e.g. via SINUMERIK Operate) to the I/O addresses of the field devices.

Configuring the F-peripherals

During the configuring of F-peripherals with Safety Integrated (SPL), you can orient yourself on
the following handling overview with sample configuring sequence. This serves, however, only
as an introduction to the configuring and programming of SINUMERIK Safety Integrated (SPL).
Therefore, observe the following documentation prior to configuring Safety Integrated (SPL):
