AS-Interface

Transmission technology

Introduction

6

■

Overview

Transmission method

A significant feature of the AS-Interface technology is the use of
a common, two-wire cable for data transmission and distribution
of auxiliary power to sensors/actuators.

An AS-Interface power supply unit, which meets the require­ments of the AS-Interface transmission technology, is used for
this system. The AS-Interface shaped cable provides mechani­cal coding and thus prevents polarity reversal; penetration
terminals are used for simple contacting.

■

Benefits

Cabinets that were previously overflowing with complicated con­trol line wiring and marshalling distributors can now be replaced
by AS-Interface.

The AS-Interface cable can be connected at any point, thanks to
specially developed wiring and connection using the insulation
displacement method.

This concept gives you tremendous flexibility and considerably
cuts costs.

The AS-Interface is a single master system. Communications
processors (CPs) are available for SIMATIC

®

systems which

control process or field communication as masters.
The system expansion now allows double the quantity of slaves

(max. 62) to be operated on AS-Interface. The analog values are
now also preprocessed in the master. For direct connection of
AS-Interface to PROFIBUS DP, DP/AS-Interface Link 20E is
available. Using this DP/AS-Interface link, the AS-Interface can
be used as a subnet for PROFIBUS DP.

The AS-Interface is an open standard. Leading manufacturers
of actuators and sensors support AS-Interface worldwide.
Interested companies can obtain the electrical and mechanical
specifications from the AS-Interface Association on request.

Introduction

Configuration examples

6

■

Function

Operating modes

In general, the master interfaces distinguish between the follow­ing operating modes:

I/O data transfer

The inputs and outputs of the binary AS-Interface slaves are
read and written in this operating mode.

Analog value transmission
The AS-Interface masters according to the Complete

AS-Interface Specification V2.1 support integrated analog value
processing. This means that data exchange with analog

AS-Interface slaves (according to analog profile 7.3 or 7.4) is just
as easy as with digital slaves.

Command interface

In addition to the I/O data exchange with binary and analog AS­Interface slaves, the AS-Interface masters offer a range of addi­tional functions through the command interface.
This means that, from user programs, slave addresses can be
assigned, parameter values can be transferred and diagnostic
information can be read out.

■

Design

Process or field communication

AS-Interface is used wherever individual actuators and sensors
are physically distributed throughout the machine (e.g. in a bot­tling plant or on a production line).
AS-Interface replaces complicated wiring harnesses and con­nects binary and analog actuators and sensors, such as proxim­ity switches, valves or indicator lights, to a controller (e.g. SI­MATIC) or PC.

In practice this means: The installation runs without problems
because data and power are transported through a single com­mon cable. No specialist know-how is required for installation
and startup. In addition, the simple installation and clear struc­turing of the wiring and special cable design not only consider­ably reduce the risk of faults but also reduce service and main­tenance costs.

AS-Interface

A/B technique

6

■

Overview

The A/B technique concept

The AS-Interface specification 2.1 allows a doubling of network
stations from 31 to 62. The 31 addresses that can be assigned
in an AS-Interface network can be split into two mutually inde­pendent sub-addresses, e.g. in 1A and 1B.

If this is utilized for all 31 slaves, up to 62 slaves can be con­nected within an AS-Interface network. The so-called A/B slaves
can each have up to four inputs and three outputs.

Another new feature of the new AS-Interface specification V2.1
is integrated analog value transfer. In this case, integrated
means that no special function blocks are required in order to
access the analog values. Accessing data is therefore just as
easy in the case of analog values as it is with digital values. In­tegrated analog value transfer can be used with analog slaves
that support Proifiles 7.3 and 7.4.

AS-Interface master

To operate A/B slaves in an AS-Interface network, master mod­ules working according to the specification 2.1 must also be
used. The A/B technique is supported by the SIMATIC S7
masters and the DP/AS-Interface links from Siemens. To masters
that do not support specification 2.1, only standard and A slaves
can be connected.

The sub-address of A/B slaves is set to “A” by default.
Masters and slaves that are already working to the new specifi-

cation are identified accordingly in the catalog.

Addressing A/B slaves

A/B slaves can be addressed like standard slaves via all com­mercial AS-Interface addressing units conforming to specifica­tion 2.1. AS-Interface addressing units that do not conform to the
new specification 2.1 can readdress A/B slaves only as A slaves.

As far as addressing is concerned, an analog slave is like a stan­dard slave. Up to 31 analog slaves can therefore be operated in
one AS-Interface segment.

Communication cycle

Standard slaves are polled in every cycle (max. cycle time:
5ms).

If only an A or B slave is installed at an address, this slave is also
polled in every cycle (max. cycle time: 5 ms).

If an A/B slave pair is installed at an address, slave A is polled in
one cycle, slave B in the next (max. cycle time: 10 ms).

If only standard and/or A slaves are installed in a network, the
cycle time is the same as for standard masters (max. cycle time:
5 ms).

■

Benefits

• Lower costs for masters and power supply units

• Enhanced decentralization in installations with numerous,
widely distributed signals

• Existing AS-Interface systems can be expanded further

Introduction

AS-Interface Safety at work

6

■

Overview

Safety included

The Safety at Work concept supports the direct integration of
components with relevance for safety, such as emergency stop
switches, protective cover switches or safety light barriers, in the
AS-Interface network. These are fully compatible with the familiar
AS-Interface components (masters, slaves, power supply units,
repeaters, etc.) in accordance with EN 50295 and are operated
in conjunction with them on the yellow AS-i cable.

The signals from the safety sensors are evaluated by a safety
monitor. This not only monitors the switching signals of the safety
sensors but also continuously checks that data is being trans­ferred correctly. The safety monitor has one or two release cir­cuits in a two-channel configuration which can be used to bring
the machine or installation into a safe state. Sensors and moni­tors can be connected at any point on the AS-Interface network.
It is also possible to use several monitors in the same network.

A failsafe controller or a special master is not necessary. The
master handles safety slaves in the same manner as all other
slaves and only receives the safety data for information pur­poses. They can therefore be used to expand any existing
AS-Interface network.

Safety at Work guarantees a maximum response time of 40 ms.
This is the time between application of the signal to the input of
the safe slave and switching off the output at the safety monitor.

Tested safety

The system has been tested and approved by the German
Technical Inspectorate (TÜV). The transmission technique for
signals with relevance for safety is designed to allow applica­tions to be implemented up to category 4 in accordance with
EN 954-1.

Software

The safety-related applications can be configured using the
configuration software and then transferred into the monitor.
Moreover, the software can also be used for online diagnostics.

■

Benefits

• A failsafe PLC or special master is not required.

• Simple system structure due to standardized AS-Interface
technique.

• Safe and non-safe data on the same bus.

• Existing systems can be expanded quickly and easily.

• Safe signals can be combined in groups.

• Integration of the safety signals in the plant diagnostics con­cept.

• Approved up to category 4 acc. to EN 954-1.

• Safety at Work is certified by the German Technical Inspec­torate (TÜV).

■

Application

Integrated safety systems using AS-Interface can be used in ap­plications for which EMERGENCY-STOP pushbuttons, protective
door locks, Stop category 0 and 1, two-handed operation and
light arrays are currently installed.

■

Design

The safety system is constructed in the same manner as the now
familiar installation of AS-Interface.

The family of safe AS-Interface products comprises the safety
monitor that monitors the safe stations. The spectrum of safe sta­tions comprises the safe modules and the safety-related sensors
with an integrated interface.

■

Function

Following a master call, the safe stations transmit their informa­tion, like the standard stations, to the master. The safety monitor
monitors this transfer from the safe stations to the master and
switches

• to the EMERGENCY-STOP status (in the case of faults in safe
stations) or

• to the safe status (in the case of a wire break).

The safety monitor is configured using software. The configura­tion comprises the input signals of the safe stations and the in­ternal functions of the safety monitor. The safety monitor offers
OR logic, AND logic, timer functions, buffer storage, etc.

■

Integration

For integration of the safety system into AS-Interface, the exist­ing infrastructure such as the master and the power supply unit
can continue to be used. For the safety system, the safety mon­itor is integrated as a monitoring component and the safe station
is integrated as the interface between the safe sensors and the
system. The safe sensors can be used as before.

Overview

The safety monitor is the core component of Safety at Work. A
safe application is configured with a PC via the safety monitor.
Various different application-specific operating modes can be
used. These include the EMERGENCY-STOP function, tumbler,
two-handed operation as well as selection of Stop category
0 or 1.

In order to fully utilize the AS-Interface diagnostic capability, the
monitor can also be operated with AS-Interface addresses as an
alternative.

Two versions of the monitor are available:

• Safety monitor with one two-channel release circuit

• Safety monitor with two two-channel release circuits

■

Function

Safety monitor with enlarged functions

Logical OR operation

In this logical operation up to six elements can be OR gated.
(Until now, only two elements could be OR gated).

Logical AND operation

In addition to the standard AND gating in the main path of an
enabling circuit, an AND operation can be inserted into an OR
operation. More than two elements can be gated in this AND.

Buffer

Temporary shutdowns are stored in a buffer for the purpose of
diagnostics.

Number of devices

The number of devices that the safety monitor can process has
been increased from 32 to 48. Applications that are larger and
more complex can now be simulated in the safety monitor.

Timer functions

Timers are offered with the functions

• Delayed switching-on

• Delayed switching-off and

• Pulse.

Compatibility

Any configurations that have been previously created can be
loaded into the "new" safety monitor without changes.

K45F Safe Compact Module

If only one single-channel switch will be connected to the mod­ule, this must be connected to Channel 1. The second channel
must be bridged. This can be performed with the M12 connector
3RK1901-1AA00 on Socket 2.

Pin 3 of Socket 1 is connected to Pin 1 of Socket 2 and Pin 4 of
Socket 1 is connected to Pin 2 of Socket 2. If both socket pairs
are assigned, the inputs are linked.

AS-Interface position switches

6

■

Overview

Position switch from left to right:
Standard / Standard, with M12 connector / with tumbler

It is also possible now to directly connect SIGUARD position
switches via the standard AS-Interface with safety-oriented com­munication. In this case, the safety functions no longer have to
be conventionally wired up.

Position switches convert the mechanical positions of moving
machine components into electrical signals.

■

Application

Position switch with separate actuator

The position switches with separate actuator are used in appli­cations in which the position of doors, covers or guards has to
be monitored for safety reasons.

The position switch can only be switched using the associated
coded actuator. It is not possible to bypass it manually or using
a tool.

Position switch with tumbler

The position switches with tumblers are special safety devices
that prevent the inadvertent or intentional opening of protective
doors, guards or other covers when a dangerous state exists,
e.g. for coastdown movements of the switched-off machine.

The safety switch with tumbler has two main tasks:

• Enabling the machine when the protective device is closed
and locked

• Disabling the machine when the protective device is open

The position switch can only be switched using the associated
coded actuator. It is not possible to bypass it manually or using
a tool.

■

Overview

It is also possible to connect AS-Interface cable-operated
switches via the standard AS-Interface with safety-oriented com­munication.

In this case, the safety functions no longer have to be conven­tionally wired up.

■

Application

SIGUARD cable-operated switches are used for monitoring or
for EMERGENCY-STOP facilities on particulary endangered sys­tem sections.

As the effective range of a cable-operated switch is limited by
the length of the cord, large systems can also be protected.

Specifications

Switches with latching for implementation in EMERGENCY-STOP
equipment correspond to the EN 418 standard.

■

Function

The safety contacts of the AS-Interface cable-operated switch
are positively driven.

The AS-Interface cable-operated switches are ready to operate
after pretensioning of the pull-wire or the rope.

When the rope is pretensioned, it must be released before the
cable-operated switch can be returned to the original state.

safety mats).

For further details, see the manual "Safety Integrated“ and the
operating instructions for the respective devices.

■

Benefits

• Double-scan function

• Cascading of host and guest devices

• Two transmission channels

■

Design

A SIGUARD Light Curtain or light array comprises a transmitter
and a receiver that must be mounted opposite each other.
Depending on the resolution and length, a specific number of
transmit and receive diodes are arranged in a vertical row.
The infra-red LEDs of the transmitter send short light pulses that
are received by the receive diodes.

SIGUARD Light Curtains:

• Resolution 14, 30 and 50 mm,

• Length 150 mm to 3 m,

• Cascading of master and slave devices to create larger height
or length of protective zone or for angular arrangement.

SIGUARD Light Arrays:

• 2-, 3- or 4-beam for access protection.

Standards

• EN 61 496-1, -2, IEC 61 496-1, -2 (requirements for non-contact
protection systems)

• EN 999 (incl. calculation of safety clearances)

• EN 954-1 (safety of machines, safety-related parts of controls).

Overview

The LS4 Laser Scanner is an optical distance sensor. The device
periodically transmits light pulses within an operating range of
190°.

If the pulses hit an obstruction or a person, the light is reflected
and then received and evaluated by the LS4 laser scanner. The
scanner calculates the precise coordinates of the obstruction
"seen" from the light propagation time.

If the obstruction or the person is located within defined ranges,
a Stop function is executed. Switch-off is then performed via the
safe interface within the system response time.

The Stop function is reset when the protective zone is free again,
depending on the operating mode, either automatically or follow­ing acknowledgement.

Accessories

Accessories include a twistable mounting support, suitable pre­assembled connecting cables in diverse lengths as well as
spare parts.

Application

Horizontal danger zone protection

Reliable detection of persons and objects in danger zones of
machines and plants

Flexible configuration of any protection and warning zones to a
great extent

Horizontal danger zone protection with several zones
to be protected

Safe detection of persons in various danger zones by switching
over protection zones

Better availability when specifically securing only live zones

Route monitoring for driverless transport systems

Detection of persons and objects that approach the vehicle
The laser scanner offers a greater protection range than

bumpers and therefore permits higher speeds.

Collision protection for shifting units

Protection of persons who are in the path of the vehicle
Objects in the path of the vehicle are detected early; damage to

the vehicle or load is therefore prevented.

Further applications

• All types of hazardous area protection,

• Room protection and access protection,

• Projecting object monitoring (protection of machines and
persons)

• Non-safety-related measurement or recognition tasks
(e. g. distance, position or contour recognition)

Function

Function principle

Bundled light pulses are created via a laser diode with coupled
transmission optics. These are diverted by a rotating mirror in
such a way that within 40 ms a light pulse is triggered in all angle
segments (scan rate: 25 scans/s). If the light pulse hits an object
or a person, the light is reflected and acquired and evaluated by
the scanner.

Measuring pulse propagation time

The SIGUARD LS4 laser scanner operates by measuring the
pulse propagation time. When extremely short light pulses are
emitted, a time difference occurs between the transmitted and
received light pulse. The propagation time of the light pulse is a
direct measurement of the target distance.

The operating range of the scanner (190°) is subdivided into
angle segments of 0.36°.

Protection and warning field pairs

The device has 4 switchable protection and warning field pairs.

LS4Soft operating software

The SIGUARD LS4 laser scanner must be parameterised using
the associated LS4Soft software. The personal protection and
warning fields required are set in this manner. Also configuration
parameters, such as automatic/manual start, response time and
restart time can be parameterised.
