The addressing unit is used to assign an address during commissioning to each AS-Interface slave. The device detects a connected slave module or a complete AS-i network and displays the found module in the LCD display. Each address can be set individually using the Up/Down keys. Additional commissioning functions can be selected intuitively with the rotary switch. The innovative device has been adapted to the current AS-i Specification V3.0 and can now also handle the I/O data of the latest slaves.

Functionality

• Reading out and adjusting the slave address 0 to 31 or 1A to 31A, 1B to 31B, with automatic addressing aid and prevention of double addresses
• Reading out the slave profile (IO, ID, ID2)
• Reading out and adjusting the ID1 code
• Input/output test when commissioning the slaves:
  Read input signals and write outputs with all digital and analog slaves according to AS-Interface Specification V3.0, including safe input slaves and complex CTT2 slaves
• Measuring the voltage on the AS-Interface cable (measuring range from 2 to 35 V)
• Display of the operational current in case of direct connection of an AS-i slave (measuring range from 0 to 150 mA)
• Storage of complete network configurations (profiles of all slaves) to simplify addressing
• Adjusting the slave parameters for commissioning
• Reading out the identification and diagnostics of CTT2 slaves
• Reading out the code table of safe input slaves (ASIsafe)

Note:

For operation of the addressing unit on an AS-Interface cable with connected power supply unit, the following applies:

The AS‑Interface addressing unit is suitable for standard AS‑i networks and AS‑i Power24V networks (operational voltage on the AS‑Interface cable min. 19 V).
