Electrical door interlock according to UL 508A and NFPA 79.
When implementing operating mode selection with functional safety, questions frequently arise regarding the requirements to be implemented. This application example is based on a practical safety concept - which is frequently used.
Use of an RFID card reader or SIRIUS ACT-ID key switch for access control in WinCC V7.4.
The SIMATIC ET 200AL has a high IP65/67 degree of protection, a particularly compact design, a small space requirement and low weight. It has been specially designed for distributed control electronics in confined spaces and applications involving motion.

This documentation provides an insight into the fundamental safety requirements in the manufacturing industry.
The current consumption of a fan motor, for example, rises as the filter becomes clogged.
Single-channel emergency stop shutdown of a motor by a 3SK2 safety relay and 3RT1 power contactor with fail-safe control.
Two-channel emergency stop shutdown of a motor by a fail-safe controller and 3RT1 power contactors with fail-safe controller.
Two-channel emergency stop shutdown of a motor by a 3SK2 safety relay and 3RT1 power contactors with fail-safe control.
Single-channel emergency stop shutdown of a motor by a fail-safe controller and 3RT1 power contactor with fail-safe control.
To be able to safely shut down a machine in an emergency, an emergency stop command device is attached and monitored by a safety relay. Safe shutdown takes place via fail-safe motor starters.
Single-channel emergency stop shutdown of a motor by a 3SK2 safety relay and power contactor.
To monitor access to an open danger zone, so-called non-contact protective equipment such as a light curtain can be used. If the light beam is interrupted, a shutdown signal is triggered.
This application uses a concrete example to illustrate the simple connection of Siemens IO-Link devices to a SIMATIC S7-CPU using block library "Siemens IO-Link Devices".
