The fail-safe modules of ET 200SP expand the range of the ET 200SP family. They are incorporated seamlessly into the Safety Integrated concept as with ET 200S / ET 200M / ET 200iSP and ET200pro. Safety-related communication via PROFIsafe is also supported. The fail-safe modules for digital inputs and outputs (DI and DQ) are the same size as the standard modules. Their functional safety is certified in accordance with IEC 61508. They are designed for safety-related use up to SIL 3 according to IEC 62061 and PL e according to ISO 13849.

One special feature of the F modules of SIMATIC ET 200SP is that the F addresses no longer have to be set manually by means of the DIP switches on the module. They are now assigned during commissioning using the engineering function. When replacing a module, the F address modules remain in the coding of the BaseUnit. If a new module is inserted, these F addresses are transferred automatically. New assignment of the F addresses is therefore unnecessary. This new feature simplifies the setting process and saves time.

Safety-related groups of standard or fail-safe DQ modules can be switched off using the SIMATIC ET 200SP fail-safe power module. Evaluation of the safety function is then carried out either in the F-CPU or in the F-PM-E power module. This fast and direct group switch-off can be carried out up to SIL 3 / Pl e.

Totally Integrated Automation (TIA)

Safety technology (Safety Integrated) is a component of Totally Integrated Automation, which provides total integration of safety automation and standard automation.

Where standard automation (classical PLCs) and safety automation (electro-mechanics) are still separate today, these two worlds are growing together into a uniform, integrated overall system. Siemens is thus able to present itself as a complete supplier of automation technology, in which safety engineering is part of the standard automation and system-wide integration exists.
