The serial diagnostics field includes safety switchgear, system components and installation accessories for safety interlocks, safety sensors and operating panels with SD interface.The SD interface allows comprehensive diagnostic data (switch states such as 'door open/closed' or error messages such as 'actuator in limit area' or 'excess temperature') from series connected safety switchgear to be transmitted to superior machine control systems. The data is transmitted via an SD gateway with industrial fieldbus protocols (PROFIBUS, CANopen, PROFINET IO, EtherNet IP, Modbus/TCP, EtherCAT).

The SD interface also allows safety interlocks to be locked and unlocked individually, as well as configured. As such, the latching force of the MZM100-SD electromagnetic solenoid interlock can be set by SD interface.

Benefits of the SD interfaceComprehensive status and diagnostic data

  • Simplified troubleshooting
  • Avoidance of unscheduled machine downtimes thanks to faster error alerts
  • Performance Level PL e despite series connection of safety switchgear
  • Saving on secure inputs by creating switch-off circuits
  • Support for different fieldbus systems
  • Smooth and fail-safe installation
