New proximity switch for mechanical handling
Siemens Automation and Drives is extending its family of Opto-BERO 3RG7 proximity switches to include a new optical sensor, which has been specifically designed for the mechanical handling market.
The 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 4 F-DI / 3 F-DO 24VDC/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.
