The safety-related SIMATIC controllers are based on a standard controller whose operating system and hardware components have been expanded by a variety of different protection mechanisms. They can thus also be used as standard controllers.
Safety-related tasks can thus be implemented cost effectively with just one controller, or, as before, separately.
The safety controllers can be expanded with the safety-related signal modules of the ET 200M, ET 200S, ET 200pro (IP67) and/or the block I/O ET 200eco (IP67).
Communication between two safety controllers or between one safety controller and assigned safety I/O takes place via PROFIBUS or PROFINET using the PROFIsafe profile.
The safety SIMATIC controllers are based on different hardware and software architectures. You can choose from different designs and CPU classes:
- SIMATIC S7-mEC-RTX F:
safety, embedded controller in S7-300 design pre-installed with Windows XP Embedded
and the SIMATIC WinAC RTX F S7 software controller
- SIMATIC IPC427C-RTX F:
safety, embedded, turnkey DIN rail PC pre-installed with Windows XP Embedded and the
SIMATIC WinAC RTX F S7 software controller
- SIMATIC HMI IPC477C-RTX F:
fail-safe panel PC pre-installed with Windows XP Embedded (Compact Flash Card) and
S7 Software-Controller WinAC RTX F
Range of application
Safety systems provide the highest level of safety for humans, machines and environment. They are used to prevent accidents and damage resulting from a fault or malfunction. The safety SIMATIC controllers (SIMATIC Safety Integrated) monitor themselves, detect faults autonomously and immediately change into or remain in a safe mode when a fault occurs. They are optimized for use in production engineering and provide air-tight safety for all its many facets.
