Interfaces
The safety relay can be accessed by Safety ES via an RS232, USB or eldbus interface. The
communication via the eldbus interface is implemented via an optional interface module.
WARNING
Unauthorized access to safety functions via eldbus.
Can Cause Death or Serious Injury.
Unauthorized access to the safety relay via eldbus, such as PROFINET or PROFIBUS, can result
in conguration changes and overriding of safety functions.
To prevent unauthorized access to the safety relay via the eldbus, assign a password for
accessing the device in Safety ES. If you operate several safety relays in one eldbus network,
you must assign a separate password for each safety relay to prevent confusion when accessing
via the eldbus. In other words, the passwords must not be identical.
