Introduction to the AS-interface version 2.13
The functionality of AS-interface has been expanded to support the operation of
up to 62 AS-interface slaves on one line� Moreover, the transmission of analogue
values with AS-interface version 2�1 and higher is as simple as the transmission of
binary values�
For the addressing unit described in these operating instructions, only the extensi-
on to 62 slaves is relevant and described below�
For using the extension it is important that both the slaves and the master support
AS-interface version 2�1�
AS-interface provides 5 bits for the address in the master request message�

4
This is sufficient to address 32 slaves� In normal operation, address 0 is not per-
mitted, thus allowing 31 AS-i slaves to be operated� The address range is doubled
by using the data bit D3 as sixth bit for addressing, which enables the addressing
of 62 slaves�
For reasons of compatibility the message structure has not been changed�
Using the identification code, the master detects whether or not version 2�1 is
supported (ID code = 0A hex )� If it is a version 2�1 AS-interface slave, this slave
receives two additional identification codes (ID1 and ID2) which describe the
functionality of the slave� A special feature of these additional ID codes is that the
ID1 code can be written by the user�
If automatic addressing is used, these additional ID codes are also read and com-
pared to those of the faulty slave�
Address 0 is only changed to the address of the faulty slave if all ID codes of the
new slave correspond to those of the old slave�
AS-interface slaves which do not support version 2�1 can be used together with
AS-interface slaves which support version 2�1�
The addressing unit enables the writing of identification code ID1� If the ID code
ID1 is changed by the user and automatic addressing is used, ensure that the
correct ID code 1 was stored in the slave before installing the new slave�
With version 2�1 AS-i slaves, data bit D3 of the output data is used to differentiate
between A and B slaves� A version 2�1 AS-interface slave thus supports 4 bits of
input data and 3 bits of output data� When fully expanded, up to 248 bits of input
data and 186 bits of output data are available�
As of version 2�1, an address can be assigned twice, e�g� address 15A and 15B�
This means that the data for slave 15A is written and read in the first cycle and
the data for slave 15B in the following cycle, followed again by slave 15A� This
increases the cycle time for slaves A and B to maximum 10 ms� The cycle time of
conventional slaves remains unchanged as these are scanned in every cycle�
If an AS-interface slave is used which does not support version 2�1, an address
may be assigned only once�
Structure of the addressing unit4
The battery for AC1154 is charged when delivered� It is, however, possible that
the battery charge is inadequate due to long storage times and self-discharge�
This is indicated by a battery symbol on the display� If this symbol is displayed, the

5
UK
addressing unit needs to be recharged with the battery charger supplied with the
unit�
The structure of the AC1154 addressing unit is shown in the following figure:

The adapter is used to connect the AS-interface slave to the addressing unit�
Most AS-interface slaves can be connected directly to the adapter without any
accessories�
These include, among others, AS-interface slaves with M12 screw connections� All
AS-interface slaves with 2�5 or 3�5 mm Cinch addressing socket can be program-
med using the E70213 addressing cable�
Like some AS-interface slaves the addressing unit is supplied with an infrared in-
terface which can also be used to establish the connection to AS-interface slaves
(IR addressing adapter E70211)�
A slave with a higher current consumption than provided by the addressing unit
can be powered by an external AS-i power supply�

6
Operation with the AS-i power supply is possible but cannot be guaranteed for all
topologies� The AS-i master must be switched offline or disconnected� When ope-
rated with the AS-i power supply the addressing unit should be connected close to
the power supply�
All available slaves are then indicated in the LC display� The slave to be modified
next can be selected using the control panel�

The LC display shows the current operating
mode in the upper left-hand corner� Please
refer to the chapter "Operating Modes" for
the meaning and functions of the individual
modes�
To the right is the two-digit, 7-segment display� If the current AS-interface slave
does not support version 2�1 the letters A and B in the right-hand corner are not
displayed� If version 2�1 is supported, the letters indicate whether the current
address refers to slave A or B�

Operating modes5
Before the requested operating mode can be set, the addressing unit must be
switched on by pressing the Read/On button�
The requested operating mode is set by pressing the MODE button�
Press the MODE button until the requested operating mode is indicated in the LC
display�
Modes of the connected slaves which are not supported are skipped� For a slave
of version 2�0 for example these are the modes ID1, ID2 and PERI� For all slaves
with address 0 the modes DATA and PARA are skipped since these are not de-
fined according to the AS-interface specification�
As an alternative you can change from any mode directly to the addressing mode
by keeping the MODE button pressed�

Changing the variable values in running processes can cause serious personal
injury and damage to equipment in case of malfunctioning or program errors�
Before executing the functions DATA or PARA make sure that no dangerous
conditions can occur�
Addressing mode6
When the unit is switched on by pressing the Read/On button, it is automatically in
the addressing mode and the connected slaves are displayed� If a different mode
was used before, press the MODE button until ADDR appears in the LC display�
As an alternative you can change from any mode directly to the addressing mode
by keeping the MODE button pressed�
The Read/On button must then be pressed in order to detect the connected sla-
ves� If the addressing unit does not detect any slaves, error message F2 appears�
All detected slaves are indicated in the lower part of the display (small numbers)�
For conventional slaves neither the letter A nor B is displayed here� If new version
2�1 slaves are used, an A or B next to the address indicates whether this is an A
or B slave�

If several different slaves are connected to the addressing unit, the display swit-
ches between conventional A and B slaves (no letters) every 2 seconds�
The address of the slave which is to be written next (activated slave) flashes at
a frequency of 2 Hz� Press the Read/On button again to activate the next higher
available address�
To activate a specific slave, set the requested address in the upper-right field
using the + or - button� When one of the two buttons is pressed for the first time,
RD is no longer displayed� Then press the Read/On button�
The active address is indicated by RD being displayed to the left of it� In addition,
the activated address begins to flash in the lower field� The following example
should help illustrate this behaviour:

quicklyashing1:
In this example, the addressing unit detected the following slaves:
A example 1: slave address 10A and 12A
B example 2: slave address 10B and 11B
C example 3: conventional slaves with addresses 1, 2 and 3
The activated slave is reprogrammed to the address which is displayed in large
text in the upper-right corner of the display (10A in the example)�
Use the + button to increment the value or the - button to decrement the value�

10
If the corresponding button is pressed once, the display increases or decreases
by 1� If the button is held pressed, the addressing unit increments or decrements
continuously�
To address, use the + or - button to set the new requested address� When one
of the two buttons is pressed for the first time, RD is no longer displayed� This
indicates that the displayed value is not a value read from a slave�
If the Write/Set button is pressed, the address of the activated slave (small
flashing number) is changed to the new address� In addition, WR is displayed next
to the written address� This indicates that a slave has been readdressed� Note that
no slave has the active, flashing address any longer�
Press the Read/On button to update the display and activate the next higher
address�
To readdress, address 0 must be free� If an AS-interface slave having the address
0 is connected to the AC1154 addressing unit, error message F5 appears�
If the requested address is already assigned in the AS-interface system, error
message F4 appears�
If you try to address a conventional slave with an A or B address, error message
F6 appears� If you try to readdress a version 2�1 slave to an address without the
extension A or B, error message F7 appears�
Addressing of slaves with IR interface6.1
Using this addressing unit slaves with infrared interface can be addressed� An IR
addressing adapter (E70211) is required for this�
Every action is completed by a slave reset command and thus the connected
slave can communicate with the master again�
For addressing via the IR interface proceed as follows:
Connect the IR adapter to the M12 socket of your addressing unit�•
Switch the master offline or disconnect it from the AS-i line� For the AS-i•
SilverLine power supplies from ifm the communication can be deactivated by
repositioning the shunt from position 1-2 to position 2-3 on the power supply�
Address the slave in the addressing mode�•
Switch the master online again or connect it to the AS-i line� For the new AS-i•
SilverLine power supplies from ifm put the shunt into position 1-2 again�
