SIMOCODE pro - Fail-Safe Digital Modules
Manual, 11/2017, NEB631679702000/RS-AA/002
15
The SIMOCODE pro V motor management system has two modules/safety relays for the
safety-related tripping of motors:
● DM-F Local fail-safe digital module
● DM-F PROFIsafe fail-safe digital module
These modules conform to the general requirements for emergency stop devices or safety
circuits described in DIN EN ISO 13849 and EN 60204-1.
The maximum performance / safety integrity levels are as follows, depending on the external
circuitry:
● PL e with Category 4 according to EN ISO 13849-1 or
● SIL 3 according to IEC 61508, EN 62061.
Safety engineering and safety-related functions
● Are exclusively restricted to the fail-safe digital modules.
● Therefore have no direct impact on existing SIMOCODE pro components and concepts.
The strict separation of SIMOCODE pro standard functions and safety-related functions
prevents unwanted mutual interference between these functions and allows shared functions
to be optimally combined.
DM-F Local fail-safe digital module
The DM-F Local fail-safe digital module facilitates safety-related tripping of a motor feeder by
means of a hardware signal that is detected and evaluated by the module.
DM-F PROFIsafe fail-safe digital module
The DM-F PROFIsafe fail-safe digital module facilitates safety-related tripping of a motor
feeder from a fail-safe controller (F-CPU). The controller is controlled over
PROFIBUS / PROFINET with the fail-safe PROFIsafe profile.
