Overview
The innovated addressing unit for AS-Interface of the AS-i Specification V3.0
The addressing unit is used to assign an address during com-
missioning to each AS-Interface slave. The device detects a
connected slave module or a complete AS-i network and dis-
plays the found module in the LCD display. Each address can be
individually set using the Up/Down keys. By turning the rotary
switch, further commissioning functions are selected intuitively.
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 ac-
cording to AS-Interface Specification V3.0, including safe in-
put 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 the 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 (min. operational
voltage on the AS-Interface cable 19 V).

Benefits
•
Increased power supply to the slaves to 150 mA
•
Better utilization of the battery capacity thanks to improved
circuitry
•
Support for the current AS-i Specification V3.0
•
Expanded display for simultaneously displaying input and
output states
•
Clearly recognizable display of status of digital inputs/outputs
in binary format (0 / 1), optionally also available as hexadeci-
mal values
•
Intuitive display of analog data either as decimal, hexadecimal
or as a percentage (e.g. 100 % corresponds to input/output
value 20 mA)
•
I/O data of complex slaves (CTT2 profile) can be displayed
•
Decoded display of the input data of safe input slaves,
including code table
•
Simplification of the operating steps when setting the slave
address with automatic read back of the set address
•
Addressing cable, ready for operation even without screwing
in tight into the M12 socket, thus faster availability of the
addressing unit
•
Proven compact housing with smooth keys and rotary switch
•
Connection of standard AS-i networks possible with 30 V as
well as Power24V networks
•
Complex slaves with high operating currents can be ad-
dressed without external supply
•
Longer operating time by automatic shutdown after approx.
5 minutes (or approx. 1 minute when data exchange is active)
after last operation
•
Can be used with all types of digital and analog slaves.
•
Comprehensive and fast input/output test of plants, even for
A/B modules with 4DI/4DQ and current analog modules with
an A/B address
•
Faster and more reliable commissioning of the AS-Interface
modules
•
One-hand operation possible, with unique selection of the
functions
•
Connection via M12 socket (pin 1: ASI+; Pin 3: ASI-;
Pins 2, 4, 5: not used)
•
Universal applicability for all AS-i networks
