6ES7151-8FB00-0AB0 - Interface Module - SIEMENS

Compared to the previous version, this manual contains the following changes or additions: ● New digital electronic modules 4/8 F-DI DC24V PROFIsafe (6ES7138-4FA05- 0AB0) and 4 F-DO DC24V/2A PROFIsafe (6ES7138-4FB04-0AB0) with the following additional functions: – Module-internal diagnostic buffer – Firmware update – I&M identification data – Reduction of the residual current for the M channel of the new EM module 4 F-DO DC24V/2A PROFIsafe to max. 0.5 mA.

Safety automation systems (F-systems) are used in systems with high safety requirements. F-systems are used to control processes in which the safe state is immediately reached by switching off. This means that F-systems control processes in which direct deactivation poses no danger to humans or the environment.

The ET 200S distributed I/O system is a DP slave/IO device of the PROFIBUS DP/PROFINET IO network that can contain fail-safe modules in addition to the standard ET 200S modules. You can construct PROFIBUS DP/PROFINET IO lines using copper, fiber optic or WLAN cables (S7 Distributed Safety from version 5.4).

The fail-safe modules differ primarily from the standard ET 200S modules in their internal two-channel structure. The two integrated processors monitor each other and automatically test the input or output circuits. They switch the F-module to a safe state in the event of an error. The F-CPU communicates with the fail-safe module via the safe PROFIsafe bus profile. The fail-safe power modules are used to supply the potential group with load voltage and to safely shut down the load voltage of the standard output modules. The fail-safe digital input modules record the signal states from the safe sensors and send corresponding safety telegrams to the F-CPU. The fail-safe digital output modules are used for safe deactivation procedures with short-circuit monitoring up to the actuator.
