    Configuring 5.2 Safety-related communication with AS-Interface Safety-related communication with AS-Interface 5.2.1 Operating principle of code sequences of safe AS-i slaves For realization of safety-related communication, each safe AS-i input slave sends a code sequence over the AS-i bus. To prevent a mix-up of the AS-i input slaves on an AS-i bus, each AS-i input slave sends a different code sequence.

  • Page 36: Operating Principle Of The Safe As-I Outputs

    Configuring 5.2 Safety-related communication with AS-Interface 5.2.2 Operating principle of the safe AS-i outputs Safety-related communication for safe AS-i outputs also uses code sequences. However, they have a different data structure compared to the code sequences of safe AS-i input slaves.
  • Page 37 Configuring 5.2 Safety-related communication with AS-Interface Evaluation unit The evaluation unit reads the safety-related control commands ON or OFF on the AS-i bus and passes corresponding switching commands, e.g., to switching contacts. In case of error, e.g., communication error on the AS-i bus, the evaluation unit switches off. The evaluation unit is integrated in the safe AS-i output module to which, for example, drive contactor coils are connected.

    Configuring 5.3 AS-i bus configuration with multiple F-CM AS-i Safety ST modules AS-i bus configuration with multiple F-CM AS-i Safety ST modules The F-CM AS-i Safety ST module generates an additional physical bus load on the AS- i cable. To avoid faults due to too low levels of the communication signals on the AS-i cable, the entire bus load on the AS-i cable must not exceed a maximum value.

    Glossary 1oo1 evaluation Type of sensor evaluation. With 1oo1 evaluation, the sensor exists once. The sensor is connected to the F-module over a single channel. 1oo2 evaluation, equivalent Type of sensor evaluation. With 1oo2 evaluation, two input channels are occupied by one two-channel sensor or by two single-channel sensors.
  • Page 103 These safety-related components are fully compatible, according to EN 50 295, with the well- known AS-Interface components, e.g., master, slaves, power supply unit, etc. They can be operated together on the yellow AS-Interface cable. Siemens supplies all components for configuring a safe AS-Interface network.
  • Page 104 Glossary F-address Each fail-safe module has an F-address. For the F-CM AS-i Safety ST module, the Step 7 F-address must initially be assigned online using . You specify the F-address in the configuration. Fail-safe systems Fail-safe systems are characterized in that, when certain failures occur, the system remains in a safe state or changes over directly to another safe state.
  • Page 105 Glossary Proof test interval Time interval after which a component must be put into error-free state. The component is replaced or proof is furnished that it is entirely free of errors. Safe state The basis of the safety concept in fail-safe systems is that a safe state exists for all process variables.
