  • Page 18 1 Technical Description Meaning of the Indicators and Operator Controls: Meaning System fault. The LED is lit when: The CP 343-2 is in the protected mode and an AS-i configuration error has occurred (for example slave failed) The CP detects an internal fault (for example EEPROM defective) In response to a button command, the CP cannot execute the required mode change at the present time (for example, because there is a slave with address 0).
  • Page 19 1 Technical Description Meaning Configuration Mode The configuration mode is used during AS-i installation and commissioning. In the configuration mode, the CP 343-2 can exchange data with every AS-i slave connected to the AS-i cable (except for the AS-i slave with address ‘0’). Any AS-i slaves that are added later are detected immediately by the master and activated and included in the cyclic data exchange.
  • Page 20 1 Technical Description Characteristics of the Slave Display S If the CP 343-2 is in the configuration mode, all detected AS-i slaves are displayed. S If the CP 343-2 is in the protected mode, all activated AS-i slaves are indicated by the LED being permanently lit. Failed or existing but unconfigured AS-i slaves are indicated by the corresponding LED flashing.
