AS-Interface

Introduction

Transmission technology

■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.

6

■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.

A/B technique

■Overview

Previously 31 nodes								Slave 1		Slave 31

with A/B slaves max. 62 nodes:	Slave 1A	Slave 1B	Slave 31A	Slave 31B

Mixed operation also permissible:	Slave 1	Slave 2A	Slave 2B	Slave 31

The A/B technique concept

6 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.

G_IK10_XX_20020

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.

	Slave type	Number of slaves	Number of inputs	Number of outputs
AS-Interface standard	Standard slave	Up to 31	31 x 4 = 124	31 x 4 = 124
AS-Interface version 2.1	A/B slave	Up to 62	62 x 4 = 248	62 x 3 = 186
AS-Interface master		Communication cycle

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 specification 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.

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

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

G_IK10_XX_20021

Safety included

The Safety at Work concept supports the direct integration of

6switches, 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.components with relevance for safety, such as emergency stop

•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.

AS-Interface position switches

■Overview		■Application
		Position switch with separate actuator
		The position switches with separate actuator are used in appli-
		cations 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.

		Position switch from left to right:
		Standard / Standard, with M12 connector / with tumbler			6
		It is also possible now to directly connect SIGUARD position
		switches via the standard AS-Interface with safety-oriented com-
		munication. 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.

AS-Interface cable-operated switches

■Overview ■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.

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 conven-

6tionally wired up.

AS-Interface laser scanner LS4

■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.

AS-Interface laser scanner LS4

■Application

Horizontal danger zone protection

Route monitoring for driverless transport systems

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

Detection of persons and objects that approach the vehicle

The laser scanner offers a greater protection range than bumpers and therefore permits higher speeds.

6

Horizontal danger zone protection with several zones
to be protected	Collision protection for shifting units

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

Better availability when specifically securing only live zones

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)

AS-Interface Safety at work

AS-Interface laser scanner LS4

■Function

Function principle

Protection and warning field pairs

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

6the scanner.

Measuring pulse propagation time

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.

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°.
