AS-Interface Version 2.1 Introduction
Leuze electronic APG-02 7
TNT 35/7-24V DEUTSCHENGLISHFRANÇAISITALIANOESPAÑOLNEDERLANDS
5 AS-Interface Version 2.1 Introduction
The functionality of AS-Interface has been expanded to support the operation of up to 62 AS-
Interface slaves on one branch. Moreover, the transmission of analogue values with AS-Inter-
face Version 2.1 and higher is as simple as transmitting binary values.
For the AS-Interface-Handheld APG-02 described in this manual, only the extension to 62 sub-
scribers described below is relevant.
In order for the extension to be used, it is important that both the slaves as well as the master
support AS-Interface Version 2.1.
AS-Interface makes available 5 bits for the address in the master request telegram. This is suf-
ficient to address 32 subscribers. In normal operation, address 0 is not permitted, thus allowing
31 AS-Interface slaves to be operated. The address space will be doubled using data bit D3
as sixth bit for addressing. So 62 slaves will be addressed.
For reasons of compatibility, the telegram frame cannot be changed.
Using the identification code, the master detects whether or not Version 2.1 is supported (ID
code = 0Ahex). If it is a Version 2.1 AS-Interface slave, this slave receives two additional iden-
tification 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.
The automatic change of addressing a slave with address 0 by a master will only be executed
when all ID codes of the new slave match those of the old slave.
AS-Interface slaves which do not support Version 2.1 can be operated
in mixed operation with AS-Interface slaves which do support
Version 2.1.
The AS-Interface-Handheld APG-02 permits the writing of identification
code ID1.
If the ID-code ID1 is changed with an AS-Interface-Handheld by the
user and automatic address programming is used, make certain that
the correct ID-code 1 was stored in the slave before installing the new
slave.

AS-Interface Version 2.1 Introduction
8 APG-02 Leuze electronic
DEUTSCH ENGLISH FRANÇAIS ITALIANO ESPAÑOL NEDERLANDS
In Versions 2.0 and earlier, AS-Interface supports 4 bits of input data (data from the field to the
host) and 4 bits of output data (data from the host to the field) per slave. With Version 2.1 AS-
Interface slaves, one bit of the output data is used to differentiate between so-called A slaves
and B slaves. A Version 2.1 AS-Interface slave thus supports 4 bits of input data and 3 bits of
output data. This means, when fully expanded, up to 248 bits of input data and 186 bits of out-
put data.
As of Version 2.1, an address can be assigned twice, e. g. address 15A and 15B. In the field,
this means that the data for slave 15A are 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 queried 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 AS-Interface-Handheld
Leuze electronic APG-02 9
TNT 35/7-24V DEUTSCHENGLISHFRANÇAISITALIANOESPAÑOLNEDERLANDS
6 Structure of the AS-Interface-Handheld
The structure of the APG-02 is shown in the following figure:
The adapter is used to connect the AS-Interface slave to the AS-Interface-Handheld. Most AS-
Interface slaves can be connected directly to the adapter without the use of any accessories.
All AS-Interface slaves with a 2.5 mm or 3.5 mm Cinch addressing socket can be programmed
using the adressing cable .
AS-Interface slaves with an infrared programming interface can be programmed via the
addressing cable.
The device can program and display all slave ICs of a multislave at the same time.
The battery for the APG-02 is charged on delivery. It is, however, pos-
sible 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 illuminates, the AS-Interface-Handheld needs to be
recharged with the battery charger.
For safety reasons, the AS-Interface-Handheld must only be charged
using the power pack supplied. The power pack must not be connected
while the AS-Interface-Handheld is connected to the AS-Interface
power supply.

DEUTSCH ENGLISH FRANÇAIS ITALIANO ESPAÑOL NEDERLANDS
A slave with a higher current consumption then the one provided by the AS-Interface-Handheld
can be powered by an external AS-Interface power supply.
All available slaves are then displayed in the LCD. The slave on which changes are to be made
next can be selected from the control panel.
The LCD displays the current operating mode in the
upper left-hand corner. Please refer to chapter 7 for
the meanings and functions of the individual modes.
To the right is the two-digit, seven-segment display. If
the current AS-Interface slave does not support Versi-
on 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.
There are five buttons on the control panel which can be used to operate the AS-Interface-
Handheld. They have the following meanings:
Operation at the AS-Interface power supply is possible but cannot be
guaranteed for all topologies. The AS-interface master has to be put off-
line resp. disconnected. When operated at the AS-Interface power sup-
ply the AS-Interface-Handheld should be connected close to the power
supply.

7.1 Addressing Mode
When the device is switched on by pressing the ADR button, it is automatically in the addres-
sing mode and the connected subscribers are displayed.
If a different mode is to be used first, press the MODE button until ADDR appears in the LCD.
The ADR button must then be pressed in order to detect the connected subscribers.
All detected subscribers are displayed in the lower part of the display (small numbers). For con-
ventional 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 the given slave is slave A or slave B.
If several different subscribers are connected to the AS-Interface-Handheld, the display swit-
ches between conventional (no letters) A slaves and B slaves 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 ADR button again to activate the next higher available address.
To activate a specific slave, set the desired address in the upper-right field using the or
button. When one of the two buttons is first pressed, the RD display is extinguished. Then
press the ADR button.
An RD displayed to the left indicates that the activated address is being handled. In addition,
the activated address begins to flash in the lower field. The following example should help il-
lustrate this behavior:
If the AS-Interface-Handheld does not detect any slaves, error message
F2 appears.

TNT 35/7-24V DEUTSCHENGLISHFRANÇAISITALIANOESPAÑOLNEDERLANDS
In this example, the AS-Interface-Handheld detected the following slaves:
• slave addresses 10A and 12A (display 1)
• slave addresses 10B and 11B (display 2)
• conventional slaves with the addresses 1, 2 and 3 (display 3)
In this example, only the address 10A (display 1) flashes rapidly. This is, thus, the activated
slave which is to be written next.
The activated slave is reprogrammed to the address which is displayed in large text in the up-
per-right corner of the display (10A in the example).
Use the button to increment the value or the button to decrement the value. If the but-
ton is pressed once, the display increases or decreases by 1. If the button is held pressed, the
AS-Interface-Handheld increments or decrements continuously.
To address, use the or button to set the new desired address. When one of the two
buttons is first pressed, the RD display is extinguished. This indicates that the displayed value
does not refer to a value read from a slave.
If the PRG button is pressed, the activated slave (small flashing number) is reprogrammed to
the new address. In addition, the display WR appears next to the written address. This indi-
cates that a slave has been readdressed. Note that there is no longer a slave present at the
active, flashing address. Press the ADR button to update the display and activate the next hig-
her address.
If the desired address is already assigned at the AS-Interface, error message F4
appears.
If you attempt to describe a conventional slave with an A or B address, error message F6 ap-
pears. If you attempt to readdress a Version 2.1 slave to an address without the extension A
or B, error message F7 appears.
To readdress, the address 0 must be free. If an AS-Interface slave is
connected to the AS-Interface-Handheld with the address 0, error mes-
sage F5 appears.

Operating Modes
14 APG-02 Leuze electronic
DEUTSCH ENGLISH FRANÇAIS ITALIANO ESPAÑOL NEDERLANDS
7.2 Other Operating Modes
Using the following operating modes, a wide range of AS-Interface data can be read and writ-
ten. Several of these modes are for functional tests only.
Press the MODE button to set the desired operating mode.
7.2.1 Read ID-code or ID-code 2
If the Read ID-code or Read ID-code 2 mode is switched on by pressing the MODE button, the
displays shows the corresponding ID-Code for the activated slave. This ID code can be read
but not written. The function Read ID-code 2 is only supported by Version 2.1 slaves.
7.2.2 Read and Write ID-code 1
If the ID1 mode is switched on by pressing the MODE button, the current value appears in the
upper-right corner of the display. In addition, the RD display appears, indicating that the current
value is a read value.
Use the or button to set the desired value. When one of the two buttons is first
pressed, the RD display is extinguished. If the desired ID1-code is displayed, it can be stored
in a nonvolatile manner in the slave by pressing the PRG button.
.
In all operating modes, the slave from which data are to be read or to
which data are to be written must first be activated in the addressing
mode (display ADDR in the display)
This function is only supported by Version 2.1 slaves.
To write ID-code 1, address 0 must be free. If an AS-Interface slave is to
be connected to the AS-Interface-Handheld with address 0, error mes-
sage F5 appears.
If automatic address programming is used in the event of a malfunction,
the new slave must have the same ID1 and ID2 codes as the slave
which is being replaced.

Operating Modes
Leuze electronic APG-02 15
TNT 35/7-24V DEUTSCHENGLISHFRANÇAISITALIANOESPAÑOLNEDERLANDS
7.2.3 Read IO-code
If the Read IO-code mode is switched on by pressing the MODE button, the display shows the
IO-code of the activated slave. It is not possible to change this value.
7.2.4 Read and Write Data
A special feature of this operating mode is that the AS-Interface supply voltage is not switched
off following the read or write operation. As a result, output data which have been written are
retained until the operating mode is changed or the connection between the AS-Interface-
Handheld and the AS-Interface slave is interrupted. Please note that this operating mode
places a large load on the battery.
First activate the slave from which you would like to read data or the slave to which you would
like to write data.
To switch on the read and write data mode, press the button MODE until DATA appears in the
display. When this mode is switched on, the current input data are read in and displayed in the
upper-right corner of the display. In addition, the RD display appears, indicating that the data
are read data.
To write data, use the or button to set the desired value. When one of the two buttons
is first pressed, the RD display is extinguished.
Upon pressing the PRG button, the data are transmitted once to the slave and the WR display
appears in the display. If the PRG button is held pressed, data are transmitted to the slave until
the button is released.
This operating mode is for test purposes only. It is not possible to over-
write the output data of the primary controller.
The AS-Interface-Handheld transmits data as long as the PRG or ADR
button is pressed.
Many AS-Interface products have an integrated watchdog, i. e. if no
AS-Interface telegram is received from the subscriber after a predefined
period of time, the output is switched to the safe (power-free) state. It is,
thus, possible that the set outputs are reset at the same time as the
PRG or ADR button is released.

Operating Modes
16 APG-02 Leuze electronic
DEUTSCH ENGLISH FRANÇAIS ITALIANO ESPAÑOL NEDERLANDS
7.2.5 Display and Write Parameters
A special feature of this operating mode is that the AS-Interface supply voltage is not switched
off following the read or write operation. Please note that this operating mode places a large
load on the battery.
First activate the slave to which you would like to write parameter values.
To switch on the Display and Write Parameters operating mode, press the MODE button until
PARA appears in the display. When this mode is switched on, the default parameters are dis-
played in the upper-right corner.
To write parameters, use the or button to set the desired value. When one of the two
buttons is first pressed, the RD display is extinguished.
Upon pressing the PRG button, the parameters are transmitted once to the slave and the WR
display appears in the display. As long as the activated AS-Interface slave is connected to the
AS-Interface-Handheld or as long as the PARA operating mode is switched on, the slave func-
tions using the written parameter values. If the connection is interrupted or the operating mode
is changed, the values are lost.
7.2.6 Displaying the Peripheral Fault Flag
The peripheral fault flag is an optional bit which indicates an error in the slave. This function is
only supported by Version 2.1 slaves. This flag can be read with the AS-Interface-Handheld.
Activate the slave from which you would like to read this bit.
Press the MODE button until PERI appears in the display. The display 0indicates that no error
is present, 1indicates an error.
This operating mode is for test purposes only. It is not possible to store
or configure parameter values in a nonvolatile manner in the
AS-Interface master or slave.
In this operating mode, the parameter values are not read from the
slave. When this operating mode is switched on, the default values are
displayed. If the ADR button is pressed again following the write opera-
tion to read the parameter values, this display shows the most recently
written values.
Due to the device structure, pressing the MODE button first switches on
the PARA operating mode. Press the button again to switch on the
DATA operating mode. If you switch from the PARA operating mode to
the DATA operating mode, the AS-Interface voltage remains switched
on and the parameter value retained.
