Fieldline Extension and the AS-Interface System
7513_en_01 PHOENIX CONTACT 1-1
1 Fieldline Extension and the AS-Interface System
1.1 Fieldline Extension AS-Interface Product Group
Fieldline Extension is an extension of the existing Fieldline product range. AS-Interface
integrates seamlessly into this product range.
Easy handling is a key feature of Fieldline Extension AS-Interface devices. Innovative
technologies such as SPEEDCON fast connection technology or tool-free contacting of
FLX AS-i M12 devices to AS-Interface reduce the assembly time by 90%.
The input and output devices in the Fieldline Extension AS-Interface product group are
designed for distributed automation tasks in harsh environmental conditions. The devices
meet IP65/67 protection. The direct connection of sensors and actuators in close proximity
to the process is thus easily implemented.
In addition to components with IP65/67 protection, the Fieldline Extension
AS-Interface product group also includes other AS-Interface system components. These
include IP20 AS-Interface masters/gateways, AS-Interface power supply units, and
I/O slaves for use in the control cabinet.
AS-Interface masters are available in two versions.
The AS-Interface master for Inline can be used to connect AS-Interface to virtually all
common networks. This connection is established via the network-dependent Inline
bus coupler and the Inline local bus.
FLX ASI MA PB SF und FLX ASI MA 2 PB EF master are a Stand-Alone PROFIBUS version
for connecting AS-Interface to PROFIBUS DP networks.
The PROFIBUS masters support AS-i specification 3.0. Networks with up to 248 inputs and
248 outputs can be implemented together with different I/O devices (slaves) and IP20 or
IP65/67 protection.
They are backwards compatible which means they can also be operated with slaves of AS-
Interface specifications 2.0 or 2.1.

instructions and safety notes for configuration, installation, and operation provided in the
documentation are followed, the devices should not normally present a risk to people or
property.
1.2.2 Regulations
During device configuration, installation, startup, and maintenance, the valid safety and
accident prevention regulations for the specific application must be observed.
1.2.3 Safety Notes
NOTE:
To ensure IP65/67 protection, cover unused connections with protective caps.
NOTE:
Only operate AS-i devices with a maximum safety extra-low voltage (SELV) of 30 V
according to IEC 60950/EN 60950/VDE 0805.

1.4 Function Description of the AS-Interface System
The AS-Interface system enables the easy connection of sensors and actuators to a control
system (Actuator Sensor Interface = AS-Interface = AS-i). It replaces the considerably more
complex option of parallel cabling in machines and systems. The system simplifies the
installation of devices at sensor/actuator level and replaces the conventional cable harness
with a single cable. The AS-Interface system is therefore also a serial communication
system. As a sensor bus it directly penetrates through to the individual sensors and
actuators.
It is precisely here that AS-Interface has become established as a global standard solution.
AS-Interface is internationally standardized in standards EN 50295 and IEC 62026-2. It is
supported by most well-known manufacturers of control systems and sensors/actuators.

1.4.1 Easy Handling
In the AS-Interface system, the binary I/O device is addressed via the control system (PLC)
in the same way as when using I/O boards and a cable harness. The direct addressing of
devices and the simple electromechanical structure (penetration technique, tree structure)
also simplify retrofitting and the conversion of an AS-i system.
No special knowledge of the system, e.g., for service and maintenance, is required in order
to ensure a smooth transition from the previous star cabling to serial bus technology. The
unerring self-diagnostics of the AS-i system significantly contribute to the reduction of
system downtimes. For example, when replacing a faulty slave device it is not necessary to
assign a new address or modify the PLC program. The AS-Interface system supports the
replacement of a slave through automatic addressing.
1.4.2 Information Content of Data Telegrams
The AS-Interface system is optimized for networking the most basic devices using just a few
items of bit information per device. The data telegrams are therefore very short and have a
very simple structure. This means that the electronics to be integrated in the devices can be
created cost-effectively. The AS-i telegram contains a maximum of four data bits for
information exchange from the control system to the slave (output data) and from the slave
to the control system (input data). Both the input data and the output data are updated in
each cycle.
For more complex devices, e.g., analog devices, larger amounts of data can also be
transmitted. This data must be split and transmitted in several consecutive cycles in
multiplex mode.
1.4.3 Communication Principle
The AS-Interface system is a single master system. A bus access method is used for
communication, which ensures a defined and fast response time. Communication is always
initiated by the master, the slaves only respond to master requests. The master
communicates cyclically with all devices, which are addressed using an address that is
programmed once. A master cycle consists of the requests for all connected devices. This
communication method is known as cyclic polling.
1.4.4 Time Response
The cycle time of the AS-Interface system is deterministic and proportional to the number of
devices. A time of 150 microseconds is required per device. At full system configuration with
62 devices, the cycle time is 10 milliseconds. At the end of this time, all information that was
transferred from the control system to the Fieldline Extension AS-Interface system (the
master) has arrived at the slaves. Within this time all input data has also been read.

Fieldline Extension and the AS-Interface System
7513_en_01 PHOENIX CONTACT 1-5
1.5 AS-Interface standardization
1.5.1 AS-Interface specification
The AS Interface specification defines the complete AS-Interface system and guarantees
standardization of all system components. Three AS-Interface specifications have been
published since AS-Interface has been introduced in the mid-90s.
Standard slaves Specification 2.0 describes standard slaves. Addresses from 1 to 31 can be assigned to
standard slaves. This limits an AS-Interface network to 31 AS-Interface slaves.
Slaves with extended
addressing
Specifications 2.1 and 3.0 describe slaves with extended addressing. Addresses from 1A
to 31A and 1B to 31B may be assigned to AS-Interface slaves according to these
specifications. Thus, the possible number of AS-Interface-slaves in a network is doubled
compared with specification 2.0.
The currently valid specification is the "Complete Specification" version 3.0, revision 2.0
dated July 09, 2008 (as of August 14, 2009).

1.5.2 AS-Interface profile
Fixed defined profiles for AS-Interface guarantee manufacturer-independent compatibility.
The profiles summarize the meaning of the 4 data bits, the precise configuration, and the
precise functions of an AS-i slave.
1.5.3 Profile structure
Slave profile A slave profile comprises IO code, ID code and ID2 code.
IO code and ID code describe the basic functions of a slave. These fixed codes allow a
manufacturer-independent exchange of slave devices and guarantee compatibility among
each other. ID2 code is also fixed and describes further identification characteristics of the
slave devices.
ID1 code is not considered when a profile is created as the code can be freely changed by
the user.
Example Profile S-7.A.7 (4 inputs, 4 outputs)
Master profile AS-Interface masters are also categorized in various profiles and are standardized just like
AS-Interface slaves.
Standard masters Standard masters support up to 31 standard slaves or up to 31 slaves with extended
addressing. When using slaves with extended addressing, please note that - in this case-
addresses 1A to 31A will be supported only.
Standard masters also support only "Single Transaction" see Section 1.6 on page 1-7.
The profiles for standard masters are defined with M0 to M2.
Extended masters Extended masters support extended addressing. That means up to 62 slaves with extended
addressing. Extended masters are backwards compatible. They support "Single
Transaction" as well as "Combined Transaction" see Section 1.6 on page 1-7. The profiles
for extended masters are defined with M3 to M4.
IO code = 7 AS-Interface permits 16 different I/O configurations for the 4 data bits.
These 16 combinations are distinguished by the IO code. IO code 7, in this
example, is defined with 4 bidirectional data bits.
ID code = A The ID code describes the distinguishing features of the various slaves
and is defined by the manufacturer. It cannot be changed. In this example,
ID code A defines this slave as a slave with extended addressing.
ID2 code = 7 The ID2 code describes further distinguishing features of the various
slaves and is also defined by the manufacturer. It cannot be changed. In
this example, ID2 code 7 defines this slave as 4IN/4OUT slave with
extended addressing.

1.6 Different data transmission types
(Single/Combined Transaction)
Single Transaction AS-Interface Single Transaction permit a maximum information exchange of 4 bits.
Combined Transaction AS-Interface Combined Transaction (CTT1..5) permit an information exchange of more
than 4 bits. Further data exchange rules are needed to implement additional functions
requiring a higher data width with AS-Interface such as analog transmission or I/O versions
with inputs and outputs > 4. These rules are defined in Combined Transaction.
The data transmission package remains unchanged to ensure backwards compatibility to
older profiles. Profiles with Combined Transaction use the multiplex procedure to transmit
more than 4 data bits. That means that more than one cycle is used to transfer the data.
As data is transmitted in several cycles, this method could possibly cause higher transmis-
sion rates than a network without Combined Transaction.

1.7 System Components of the AS-Interface System
An AS-i system consists of at least the components described below.
1.7.1 Masters/Gateways
An AS-i master (gateway) is used to integrate an AS-i system into a higher-level fieldbus.
These are "intelligent" units in the AS-i system, which are responsible for serial
communication and self-diagnostics in the system. For the control system or in the higher-
level network, the AS-i system is represented in the corresponding process data, which can
be accessed in the normal way.
1.7.2 Power Supply Units
AS-Interface networks are supplied by special power supply units. These power supply
units provide as DC voltage of 29.5 V to 31.6 V at the output side. This is necessary in order
to safely operate all the sensors and actuators with the 24 V nominal voltage in the AS-i
system. In addition, with an integrated data decoupling network the power supply unit
ensures that data can superimpose the supply voltage. AS-i power supply units meet the
requirements of "functional extra-low voltages with safe isolation (PELV)". Outputs are
usually supplied separately via a black power cable. These standard power supply units
must also meet the requirements of PELV. This ensures that in the event of a device fault
the AS-i system cannot output any hazardous voltages.
1.7.3 Slaves
Through the concentration of special AS-i functions in the compact protocol chip a wide
range of termination devices can be adapted for use in the AS-i system. These termination
devices are the devices on the bus, i.e., the slaves. I/O devices are AS-i slaves, which
integrate several devices of conventional (parallel) type in AS-i systems.
Slave profile Each slave is identified by a slave profile. The slave profile is used for clear, functional
identification by the AS-i master. The specifications for this are defined in the AS-Interface
specification and comprise an ID code, two extended ID codes (ID1 code and ID2 code),
and a configuration code for inputs/outputs (IO code). This data indicates the function of the
slave.
The slave profile looks like this: S-7.A.0. It comprises the IO code, ID code, and ID2 code, it
cannot be modified and is permanently programmed by the manufacturer.
All information in the slave profile (ID, ID1, ID2, and IO code) is required in order to easily
replace slaves within an existing system. The master uses this data to check whether the

1.7.4 Cable
The entire conventional and complex parallel cabling system, which is prone to errors, is no
longer required and is replaced by a single AS-i cable. Power and data are transmitted via
a single cable. The profiled flat-ribbon cable, which is typical for AS-i, is used for data
transmission for Fieldline Extension AS-i M12 devices. The new innovative locking
mechanism for AS-i M12 devices enables tool-free connection to the AS-i flat-ribbon cable.
1.8 Topology
The topology of an AS-i network can be freely selected. The cable routing can be adapted
to the local requirements. The network can be created with a linear, star or tree structure.
Branch lines are permitted. The system can be installed like a normal electrical installation
for power distribution. The devices can be connected to the cable at any point in the system,
without having to consider the order, positions or distances. Cable termination resistors are
not required on the AS-i cable.
The only restriction that must be observed is that the total length of the cable must not
exceed 100 m. The value includes all cable lengths, i.e., even branch lines.
An AS-i network consists of the following components, see also "System Components of
the AS-Interface System" on page 1-8.
– An AS-i master/gateway
– An AS-i power supply unit
– Another power supply unit (as an option) for supplying the outputs with external
auxiliary voltage
– A maximum of 62 AS-i slaves (SPEC. 2.1/3.0) or 31 AS-i slaves (SPEC. 2.0)
– AS-i cable (flat-ribbon cable)
