The Advantage of SIMATIC S7-300 and Fail Safe I/O





The importance of safety technology is increasingly steadily. The market demands safety-oriented solutions in order to make sure that people, machines, and the environments are protected.

The new solution denoted Distributed Safety comprises the fail-safe controller S7-300F and the Distributed I/O system SIMATIC ET200S, in addition to fail-safe signal modules. The modular design of the F peripherals requires you to employ safety technology only where it is indispensable.

It is also possible to connect the fail-safe signal modules of the ET200M to the S7-300F-either centrally distributed. This new concept provides the following advantages:
• Freely programmable safe linking of sensors with actuators.
• Selective safe shutdown of actuators.
• Mixed configuration of fail safe and standard modules in one station.
• 1-bus concept, transmission of fail-safe signals and standard signals through a bus medium (PROFIBUS DP).

This new solutions offer both mechanical engineers (OEMs, system constructors) and system operators (end customers) significant benefits in comparison to conventional solutions.

Siemens safety technology is part of standard automation-while maintaining continuity over the entire system, in applications where standard automation (traditional PLCs) and safety automation (electromechanics) are still separate. Distributed safety can combine these two worlds seamlessly to create an integrated complete system. Siemens is all-in-one provider for automation systems and integrates safety technology in standard automation components.
