Siemens Automation and Drives recently launched its own Safety Integrated initiative, which includes everything from failsafe PLCs and I/O modules to emergency stop buttons and light curtains.
The new S7-300 CPU 319F is designed for top-performance applications requiring safety-related functions in standard and special mechanical equipment manufacture, such as presses and plant building.
The device has integral Profibus and Profinet interfaces, and as a proxy device it can handle standard and failsafe communication between the bus systems over Profisafe.
The safety-related program itself is created with Simatic Step 7 and S7-Distributed Safety.
The digital, failsafe ET 200S input/output module EM 4F-DI / 3F-DO 24V dc/2A is tailored to the requirements of SIL 2/Cat.3 and corresponds to requirements for standard applications in production machinery and machine tools.
The input/output module has the functions short-circuit test and discrepancy time monitoring and can be used, for example, in mixed configurations with standard modules and SIL3/Category 4 modules.
