Controller Addresses Human and Machine Safety
Siemens’ Simocode pro Safety is positioned to address the concerns of human and machine safety. Man and machine are protected by the combination of various multistage protection and monitoring functions in Simocode pro and by the safe switching off of the device. The company asserts that requirements of the IEC 61508/62061 and ISO 13849-1 standards for functional safety up to SIL 3 or PL e are satisfied. Hardware and wiring expenses are reduced, and additional outputs or peripheral devices can be omitted. Depending on the specific requirement, two different expansion modules are available and they can be easily connected to the basic Simocode pro V device. The digital module DM-F PROFIsafe is used with a safe signal where the switch-off is generated in a fail-safe controller, and is transmitted to the motor management system via the PROFIBUS/PROFIsafe. For local safety applications in which the fail-safe switch-off of the motor takes place via an emergency stop, a DM-F Local module is available. Viathe integrated diagnostic function, the user is provided with meaningful data outlining the status of the safety system.
