1.3 Description of functions AMS 304i

The AMS 304i optical laser measurement system calculates distances to fixed as well as moving system parts. The distance to be measured is calculated according to the principle of the propagation time of radiated light. Here, the light emitted by the laser diode is reflected by a reflector onto the receiving element of the laser measurement system. The AMS 304i uses the "propagation time" of the light to calculate the distance to the reflector. The high absolute measurement accuracy of the laser measurement system and the fast integration time are designed for position control applications.

With the AMS 3xxi product series, Leuze electronic makes available a range of internationally relevant interfaces. Note that each interface version listed below corresponds to a different AMS 3xx

model.

Leuze electronic

Page 21

Installation and mounting

Aligning the laser light spot in the center of the reflector

The laser light spot has to be aligned so that it always hits the center of the opposing reflector, both at close range as well as at the maximum measurement distance. To align, use the two M 5 Allen screws ("A" in figure 5.2). When aligning please ensure that the knurled nut and the lock nut ("B" in figure 5.2) are opened wide.

Attention!

To prevent the laser measurement system from moving out of alignment during continuous operation, subsequently hand-tighten the knurled nut and counterlock with the WAF 4 nut ("B" in figure 5.2). Knurled nut and nut must not be tightened until alignment has been completed.

Attention!

The device must not be opened. Failure to comply will render the guarantee void. Warranted features cannot be guaranteed after the device has been opened.

5.2.2 Mounting distances

Reflector 1 Reflector 2

Minimum parallel spacing between adjacent AMS 304i

The smallest-possible parallel spacing between adjacent AMS 304i is determined by the maximum measured distance as well as by the properties of the reflector. To prevent adjacent devices from interfering with each other the parallel distance of the laser light spots on the reflector is crucial.

Figure 5.4: Minimum parallel spacing X between adjacent AMS 304i

Min. parallel spacing of laser light spot X = 100 mm + (max. measurement distance in mm x 0.01).

Notice!

Please note that travel tolerances could cause the two laser light spots to move towards each other.

Installation and mounting

If both AMS 304i are optically separated from one another, e.g., if installed in different shelf alleys, the parallel spacing can be selected smaller, as there is no mutual interference in this case.

Minimum distance to an adjacent DDLS 200 optical data transmission device

The optical data transceivers of the DDLS 200 series and the AMS 304i do not mutually interfere with one another. Depending on the size of the used reflector, the optical data transceiver can be mounted with a minimum mounting spacing of 100 mm to the AMS 304i. The mounting spacing is independent of the distance.

5.3 Mounting the AMS 304i with laser beam deflector unit

General information

The two available deflector units are used for the 90 ° deflection of the laser beam, see "Accessory deflector unit" on page 102.

Attention!

The deflector units are designed for a maximum range of 40 m. Longer distances on request.

5.3.1 Mounting the laser beam deflector unit with integrated mounting bracket

The AMS 304i is screwed onto the mechanism of the US AMS 01 deflector unit. The mirror can be mounted for three deflection directions:

1. Upward beam deflection

2. Beam deflection to the left

3. Beam deflection to the right

The deflector unit is mounted on plane-parallel, flat walls or plant components. For errorfree position measurement, there must be an interruption-free line-of-sight between the AMS 304i… and the deflection mirror as well as between the mirror and the reflector.

Use the M5 screws to mount the deflector unit. Secure the screws with a toothed lock washer to protect against loosening caused by vibrations.

6 Reflectors

6.1 General information

The AMS 304i measures distances against a reflective tape specified by Leuze electronic. All provided specifications for the AMS 304i, such as the operating range or accuracy, can only be achieved with the reflective tape specified by Leuze electronic.

The reflective tapes are available as adhesive tapes, affixed to a metal plate and with an integrated heater especially for use at low temperatures. Reflective tapes with heating have the designation "Reflective tape …x…-H", where "H" is an abbreviation for the heating variant.

The reflective tapes/reflectors must be ordered separately. The choice of size is left to the user. In chapter 6.3, recommendations on reflector size are provided as a function of the distance that is to be measured. In any case, the user must check to determine whether the recommendation is suitable for the respective application.

6.2 Description of the reflective tape

The reflective tape consists of a white, microprism-based reflective material. The microprisms are protected with a highly transparent, hard protective layer.

Under certain circumstances, the protective layer may lead to surface reflections. The surface reflections can be directed past the AMS 304i by positioning the reflective tape at a slight incline. The inclination of the reflective tape/reflectors is described in chapter 6.4.2. The required pitch can be found in table 6.1 "Reflector pitch resulting from spacer sleeves" on page 33.

The reflective tapes are provided with a protective fo il that can ea si ly be pulled o ff . This must be removed from the reflector before the complete system is put into operation.

6.2.4 Specifications of heated reflectors

The reflective tape is affixed to a heated, thermally insulated base. The insulation results in a very high energetic efficiency.

Only the reflective tape is kept at the specified temperature by the integrated heater. Through the insulation on the back, the generated heat cannot be transferred via the steel construction. Energy costs are greatly reduced in the case of continuous heating.

6.3 Selecting reflector sizes

Depending on system design, the reflector can be mounted so that it travels on the vehicle or it can be mounted at a fixed location.

Attention!

The reflector sizes shown below are a recommendation from Leuze electronic for on-vehicle mounting of the AMS 304i. For stationary mounting of the AMS 304i, a smaller reflector is generally sufficient for all measurement distances. On the basis of the system planning and design, always check whether mechanical travel tolerances may require the use of a reflector larger than that which is recommended. This applies, in particular, when the laser measurement system is mounted on a vehicle. During travel, the laser beam must reach the reflector without interruption. For on-vehicle mounting of the AMS 304i, the reflector size must accommodate any travel tolerances that may arise and the associated "wandering" of the light spot on the reflector.

6.4 Mounting the reflector

6.4.1 General information

Self-adhesive reflective tapes

The reflective tapes of the "Reflective tape …x…-S" self-adhesive series must be affixed to a flat, clean and grease-free surface. We recommend using a separate metal plate, which is to be provided on-site.

As described in table 6.1, the reflective tape must be angled.

Reflective tapes on metal

The reflective tapes of the "Reflective tape …x…-M" series are provided with corresponding mounting holes. Spacer sleeves are provided in the packet for achieving the necessary pitch angle. For further information see table 6.1.

Heated reflectors

The reflective tapes of the "Reflective tape ...x...-H" series are provided with corresponding mounting holes. Due to the voltage supply affixed on the rear, the reflector cannot be mounted flat. Included in the package are four distance sleeves in two different lengths. Use the distance sleeves to achieve a base separation to the wall as well as the necessary pitch for avoiding surface reflection. For further information see table 6.1.

The reflector is provided with a 2 m-long connection cable for supplying with 230 V AC. Connect the cable to the closest power outlet. Observe the current consumptions listed in the specifications.

Reflectors

Attention!

Connection work must be carried out by a certified electrician.

6.4.2 Mounting the reflector

The combination of laser measurement system and reflective tape/reflector is mounted so that the laser light spot hits the tape as centered as possible and without interruption.

For this purpose, use the alignment elements provided on the AMS 304i… (see chapter 5.2 "Mounting the AMS 304i"). If necessary, remove the protective foil from the reflector.

Attention!

The "TOP" label mounted on the reflectors should be aligned the same as the connections of the AMS 304i.

Example: If the AMS 304i is mounted so that the M 12 connections are on the top, the "TOP" label of the reflector is also on the top. If the AMS 304i is mounted so that the M 12 connections are on the side, the "TOP" label of the reflector is also on the side.

Notice!

The reflector must be angled. To do this, use the spacer sleeves. Angle the reflectors so that the surface reflections of the foil seal are deflected to the left, right or upwards. Avoid a downward pitch, as additional reflections may occur on the running rails. chapter 6.4.3 gives the correct pitch with respect to the reflector size and, thus, the length of the spacers.

There is no guarantee that no condensation will occur on the optics in the extended switch-on/switch-off range due to the limited heating capacity. This parameter is available as standard, but functions only for devices with integrated heating (AMS

Notice!

When operating the AMS 304i on the PROFIBUS, the language configured in the GSD file is used in the display.

To change the language, no password needs to be entered nor must password enabling be activated. The display language is a passive operational control and is, thus, not a function parameter, per se.

Press the enter button to switch on parameter enabling.

The PWR LED illuminates orange; the display is inverted. You can now set the individual parameters on the display.

ESC ESC

Press the ESC button twice to return to the Parameter menu.

Viewing and editing parameters

As long as parameter enabling is activated, the entire AMS 304i display is inverted.

As long as parameter enabling is activated, communication between control and AMS 304i is interrupted. The continued networking via BUS OUT is retained.

Notice!

If a password was stored, parameter enabling is not possible until this password is entered, see "Password for parameter enabling" below.

Notice!

Parameters which are defined in a GSD file have priority. After deactivation of parameter enabling on the AMS 304i, the parameter defined in the control are reactivated. The address setting is not overwritten.

For the SSI interface, the communication between the control and the AMS 304i is also active the case of parameter enabling.

Notice!

Changes to the SSI parameters via display entry have immediate effect.

Password for parameter enabling

Parameter entry on the AMS 304i can be protected with a password. With the AMS 304i, the password is determined via the PROFIBUS GSD file. Thus, the password cannot be changed by means of display entry.

To activate parameter enabling via the display (e.g., for changing an address), the password defined in the GSD file must be entered. If parameter enabling has been activated after successfully entering the password, parameters can temporarily be changed via the display.

After parameter enabling is deactivated, all changes made on the display are overwritten by the GSD file. Even a possibly newly assigned password. Only a changed address remains unchanged after entry via the display.

Notice!

The master password 2301 can enable the AMS 304i at any time.

9 PROFIBUS interface

9.1 General information on PROFIBUS

The AMS 304i is designed as a PROFIBUS DP device for cyclical (V0) as well as acyclic (V1) data exchange.

For this purpose the functionality of the laser is defined via GSD parameter sets. The max. baud rate of the data to be transferred is 12 Mbit/s.

The PROFIBUS interface can be used parallel to the SSI interface. PROFIBUS and SSI interfaces are activated by default.

Notice!

The PROFIBUS interface can be activated/deactivated via the display. To activate / deactivate the interface, parameter enabling must be activated (see chapter 8.3.2). The respectively active interface is shown in the display; when PROFIBUS is activated, the address set is visible in the display.

9.3 PROFIBUS address entry

Notice!

Basic operation of the control panel/display is described in chapter 8.2. To set the address parameter enabling must be activated. The display is inverted.

Attention!

The laser measurement system is deactivated on the PROFIBUS when parameter enabling is activated via the display. The device is reactivated on the PROFIBUS after parameter enabling is exited.

9.3.1 Entering the PROFIBUS addresses via the display

To do this proceed as follows:

ª Activate parameter enabling.

ª Select the PROFIBUS submenu.

ª Select the address menu item [ ].

ª Enter the PROFIBUS address of the laser measurement system; set to a value between

1 and 126 (default: 126).

ª Deactivate parameter enabling.

9.4 PROFIBUS GSD file

PROFIBUS interface

9.4.1 General information on the GSD file

If the AMS 304i is operated in a PROFIBUS network, configuration must be performed exclusively via the PROFIBUS. The functionality of the laser measurement system is defined via modules. The parameters and their functions are structured in the GSD file using module. A user-specific configuration tool is used during PLC program creation to integrate the required modules and configure them appropriately for the measurement application.

During operation of the laser measurement system on the PROFIBUS all parameters are set to default values. If these parameters are not changed by the user, the device functions using the default settings supplied by Leuze electronic. For the default settings of the device please refer to the following module descriptions.

Notice!

At least one module in the GSD file must be activated in the configuration tool for the control, usually the Position value module.

Leuze electronic AMS 304

TNT 35/7-24V

Page 56

PROFIBUS interface

Notice!

Some controls make available a so-called "universal module". This module must not be activated for the AMS 304i.

Attention!

The AMS 304i makes available a PROFIBUS and an SSI interface. Both interfaces can be operated in parallel. If the AMS 304i is operated via the PROFIBUS, the SSI parameters must also be changed via the PROFIBUS SSI module if they differ from the default settings.

SSI parameters which are only changed via the display are overwritten by the PROFIBUS manager with the SSI (default) values stored in the GSD file.

Notice!

For test purposes parameters can be changed via the display on a laser measurement system operated on the PROFIBUS. As soon as parameter enabling is activated on the display, the device is deactivated on the PROFIBUS. All parameters set via PROFIBUS modules remain effective. Parameter changes can now be made via the display for test purposes. If parameter enabling is deactivated via the display, only the parameters set in the PROFIBUS modules and the PROFIBUS default settings are in effect.

Parameter changes made via the display are no longer in effect on the PROFIBUS!

Attention!

The laser measurement system does not permanently store parameters changed via the PROFIBUS. Following Power OFF/ON the currently configured parameters are downloaded by the PROFIBUS manager. If no PROFIBUS manager is available following Power OFF/ON, the parameters set on the display apply.

Notice!

All input and output modules described in this documentation are described from the controller's perspective:

Described inputs (I) are inputs of the control. Described outputs (O) are outputs of the control. Described parameters (P) are parameters of the GSD file in the control.

Notice!

Parameter length: 6 bytes

Sign affects position and velocity output. Selection of the measurement unit 1).

The parameter applies to all values with measurement units. The parameter applies to all interfaces. Resolution of the position value applies only to the PROFIBUS output. The reso lution does not apply to:

- Static preset

- Dynamic preset

- Offset

The SSI interface has a separate parameter for the resolution.

Count direction positive:

Counting direction negative:

The parameter applies to all interfaces. The count direction changes the sign during velocity measurement. For the SSI interface, no negative position values can be transferred. In this case, the value 0 is output at the SSI interface. A suitable offset is to be selected so that only positive values are transferred.

Output value=measurement value+offset. The parameter applies to all interfaces. Attention: If the preset is activated, it has priority over the offset. Preset and offset are not offset against each other. The resolution of the offset value is independent of the resolution selected in module

1. The entered offset applies immediately without any further release.

9.4.3.10 Module 9: Error handling procedures

Description

The module makes parameters available to handle any errors should they occur.

In the event of a temporary error in the value/velocity calculation (e.g. plausibility error caused by light beam interruption) the laser measurement system transmits the last valid measurement value for a length of time xx which is to be configured.

If the configured time is exceeded, the error display or the faulty measurement value output is activated.

Parameters

Parameter Description Rel.

Specifies which position value is to be

Position value in the case of error

Error delay (position)

No function. 0.1 Bit Always 0 0 – – Specifies whether the PLB status bit is

set immediately in the event of an error or if it is suppressed for the configured position suppression time.

Specifies in the event of an error whether the position value immediately outputs the value of the "position value in the case of error" parameter or outputs the last valid position value for the duration of the configured "error delay time".

Errors which occur are suppressed for the configured time. If no valid position value can be ascertained during the configured time, the last valid position value is output. If the error persists after the time elapses, the value stored in the "position value in the case of error" parameter is output. Specifies which velocity is to be output in the event of an error after the velocity suppression time has elapsed.

No function. 3.1 Bit Always 0 0 – – Specifies whether the PLB status bit is

9.4.3.11 Module 10: Velocity

Description

Outputs the current velocity with the configured resolution. The unit (metric or inch) is set in module 1 (position value) and also applies to the velocity. If module 1 is not configured, the AMS 304i operates with the default unit (metric).

The sign of the velocity is dependent on the count direction in module 1d.

In the default setting a positive velocity is output when the reflector moves away from the AMS 304i. When the reflector moves towards the AMS 304i, negative velocities are output. If the "negative" count direction is configured in module 1, the velocity signs are reversed.

Measurement value preparation averages all velocity values calculated during the selected period to yield a velocity value.

Parameters

9.4.3.12 Module 11: Static velocity limit value 1

Description

The static velocity limit value 1 function compares the current velocity with a velocity stored in the configuration. This occurs in the configured range, which is defined by range start and range end.

Notice!

If range start and range end are identical, velocity monitoring is not activated.

If a direction-dependent limit value check is activated via the direction selection parameter, the values of range start and range end also define the direction. The check is always performed from range start to range end. For example, if the range start is "5500" and the range end is "5000", the direction-dependent check is only performed in the direction from "5500" to "5000". The limit value is not active in the opposite direction.

If the check is independent of direction, the order of range start and range end is irrelevant. Depending on the selected switching mode, if the value is above or below the defined limits, the limit value status in module 16 is set and, if configured, the output is appropriately set via module 4 or 5.

Parameters

Description

The module defines the parameters for the SSI interface.

Attention!

The SSI interface can only represent posi tive distance values. If negative output values are ascertained due to the offset or count direction, a zero value is output at the SSI interface! In the event of a number overflow, all data bits are set to "1".

The unit, offset and count direction parameters of module 1 also apply to the SSI interface.

Notice!

If the SSI interface is not configured via module 17 (SSI interface) in PROFIBUS operation, the SSI interface is deactivated.

If the SSI interface is operated without PROFIBUS (PROFIBUS OFF/SSI ON), configuration is performed via the display.

9.4.3.21 Module 19: free resolution

Description

Free resolution is used when the resolutions set in the standard are not appropriate. If a free resolution is used, it must be activated in module 18.

Module 18 and module 1d must be set to configure the free resolution.

Parameters

Parameter Description Rel.

This module allows the output mea-

Free resolution velocity

Parameter length: 4 bytes

surement values for position and velocity to be freely scaled. The parameters apply to all interfaces for which the “free resolution” resolu tion was selected. The internal measurement value is multiplied by the set value on the basis of (mm/1000). Example: Value “3000” means that in the event of a change in the measure ment value by 3 mm, the position value in the binary code changes by binary 1. Due to the free resolution in the example, an internal measurement value of 3333

mm gives an output value of “1111”. The resolution of the “Offset", "Preset" and "Limit values" parameters is not affected by free resolution.

10 SSI

10.1 Principle functionality of the SSI interface

Data communication of the SSI interface is based on differential transmission as used for

RS 422 interfaces. Transmission of the position value, beginning with the MSB (most

significant bit), is thus synchronised with a clock cycle (CLOCK) specified by the control.

In the quiescent state both the clock line as well as the data line are at HIGH level. At the

first HIGH-LOW edge (point 1 in figure 10.1) the data in the internal register are stored. Thus

it is ensured that the data cannot change during serial transmission.

When the next clock signal change from LOW to HIGH level (point 2 in figure 10.1) occurs

transmission of the position value begins with the most significant bit (MSB). With each

successive change of the clock signal from LOW to HIGH level the next least-significant bit

is transmitted on the data line. After the least significant bit (LSB) has been output, the clock

signal switches from LOW to HIGH for one last time and the data line switches to LOW level

(end of transmission).

A monoflop retriggered by the clock signal determines the time span before the SSI interface

can be called for the next transmission. This results in the minimum pause time between

two successive clock cycles. If time tm = 20 μs has elapsed, the data line is returned to the

quiescent level (HIGH) (point 3 in figure 10.1). This signals completed data communication

and that the device is again ready for transmission.

Notice!

If the off-cycle of data transmission is interrupted for longer than tm = 20 μs, the next cycle

will begin with a completely new transmission cycle with a newly calculated value.

If a new transmission cycle is started before time t

again.

has elapsed, the previous value is output

SSI

Attention!

The SSI interface can only represent positive distance values. I f negative output values

are ascertained due to the offset or count direction, a zero value is output at the SSI

interface! In the event of a number overflow, all data bits are set to "1".

Notice!

In the default setting the LSB bit is the error bit.

Attention!

Significance of the error bit:

By default a 25th error bit (LSB) is appended to the 24-bit measurement value. The error bit is not included in the Gray coding of the measurement value. The error bit is 1 = active, 0 = not active.

Notice!

The data can be read out with a clock rate between 80 kHz and 800 kHz.

Attention!

Updating the measurement values on the SSI interface of the AMS 304i:

The measurement value on the SSI interface of the AMS 304i is updated every 1.7 ms (default) independent of the clock frequency. The update rate on the interface can be reduced to 0.2 ms via the display under the SSI menu item or in PROFIBUS module 17. The shorter update rate is only valid for the SSI interface and has no influence on the PROFIBUS DP interface.

10.3 General Information to the AMS 304i parameters

Attention!

Using the PROFIBUS and SSI interface simultaneously:

The SSI interface settings are performed by the PROFIBUS. If settings which differ from the default settings for the parameters, are to be used, they must be configured via module 17 (SSI interface).

Using the SSI interface without PROFIBUS: For this operating mode deactivate the PROFIBUS via the display (PROFIBUS = OFF). Default parameters are stored in the laser measurement system for the sole use of the SSI interface. The preset default parameters can be changed at any time via the display. This also applies when using parameters which do not relate directly to the SSI interface (for example: I/O 1 or I/O 2, position value or others). The SSI interface remains active even during parameter enabling. Changes to parameters have an immediate effect.
