Introduction


Introduction

The LaserSpeed I/O Module is used to translate the serial output data, Speed,

Length and Gauge Status, from a LaserSpeed 8000 or 9000 Series Gauge to a

parallel output. Optional Profibus and Ethernet field bus are also available in the

I/O Module. The I/O Module connects to the LS9000/LS8000 gauge through a

gauge cable via an RS422 connection, and provides a pass-through connector

for direct access to all the Inputs and Outputs of the LS9000/LS8000 Series

Gauge. A Light Stack connector provides signals to drive a visual indicator (a

light stack) to display the status of the gauge. The I/O Module can also be used

calculate the Elongation Ratio/Differential Speed between two LS8000/LS9000

Series gauges. In addition, the I/O Module can be used to synchronize the

outputs of multiple gauges to output their data at the same time.

Rear Panel Pin-outs

The following sections describe the various connections to the I/O Module’s rear

panel. Refer to the LS9000/LS8000 Instruction Handbook for further information

about connections to the Gauge.

Power

Accepts IEC 320 power cords. AC power requirements are 90-260VAC,

50/60Hz, 1.5Amps.

I/O Setup

A computer can be connected to this port using a straight-through 9-pin serial

cable for diagnostics and configuration. LaserTrak 4.0 can be used to configure

the LaserSpeed gauge through this port. A NULL modem is not required.

Display

Connects directly to the LaserSpeed I/O Module Display, part number 85871.

This is an LCD indicator that shows the current Length, Velocity, Quality Factor,

and Status.

LaserSpeed Gauge

TO GAUGE 37 pin D connector for connection to the LaserSpeed gauge

cable. This connector is compatible with all cables that have

part number 85277.

PASS-THROUGH Passes signals from the DB25 connector on a

LS9000/LS8000. The pinout of this connector is compatible

with 25-pin LaserSpeed breakout boxes. Signal descriptions

are listed in a table below.

ETHERNET Pass-through connector for the LS9000/LS8000 gauge’s

optional Ethernet connection that provides a direct

connection to the gauge over Ethernet. If the attached

gauge does not have the Ethernet option installed, then this

connector is not used.

RS-232 Pass-through connector for the LS9000/LS8000 gauge’s RS-

232 serial port. This connector can be connected to a PC

using a straight-through DB9 serial cable. LaserTrak or a

terminal program can be used to communicate directly with

the gauge via this serial port.


Installation


SYNC IN and OUT connector

Used to connect multiple I/O modules together for gauge-gauge synchronization,

and Elongation/Differential Speed calculation. The Sync Out connector of one

I/O module connects to the Sync In connector of the next I/O Module with a

straight-through RJ-45 cable.

IN Connects to the Master I/O module.

OUT Connects to SYNC IN of the next I/O Module in the Daisy Chain.

Parallel Outputs

STATUS Parallel Output for Status / Interlock Control / Shutter Control

VELOCITY Parallel output for Velocity

LENGTH/ELONGATION Parallel output for Length or Elongation Ratio

The LENGTH/ELONGATION port can output either Length or the Elongation

Ratio between two gauges, depending on the I/O Module’s position in the

system. All I/O Modules except for the last I/O module in the Daisy Chain

calculate the Elongation Ratio or Differential Speed. The last I/O module in the

Daisy Chain always outputs Length on the Length/Elongation port. All other I/O

Modules output Elongation Ratio if the port is configured for Auto-Elongation

Mode. The ~I:Elongation command is used to configure this mode. By default,

the ~I:Elongation setting should be set to 1 on all I/O Modules. This will cause

the I/O Module to automatically output Elongation if it is being calculated. See

the Elongation/Synchronization section for more information about Elongation.

Note: Elongation Ratio will only be calculated when two gauges are synchronized

together by connecting the Sync Out of one I/O Module to the Sync In of the

other I/O Modules.

Installation


Analog Outputs

Pins 32-37 of the SYSTEM STATUS port are used for various analog outputs.

Every I/O Module contains three analog outputs.

Elongation Analog Output – only used when using multiple I/O modules

are configured for Synchronization.

Velocity Analog Output

Quality Factor Analog Output

All analog outputs are non-isolated. You may set the scaling of the elongation

and speed outputs to fit your application. See the Serial Commands section.


Installation


Parallel Outputs

Data is updated to the bus in one of two modes. The first is called "Data Ready"

mode and the other is called "Data Request" mode. In "Data Ready" mode, the

system will automatically update the data on the Parallel Output Bus each User

Update Period. In "Data Request" mode, the system will update the data on the

Parallel Output Bus only when a Data Requested Signal is received on the Data

Request Input Pin. There are Data Request Input Pins on the Parallel Length/

Elongation port and the Parallel Velocity port. The data output mode is

configured by ~I:AckMode serial command:

Command Parallel Port Mode

~I:AckMode=0 Data Ready Mode

~I:AckMode=1 Data Request Mode

Data Ready Mode

In Data Ready mode, the I/O module outputs data each time a new measurement

is received from the LaserSpeed gauge. An optically isolated signal called "Data

Ready," located on the Length/Elongation and the Velocity Output connectors,

are provided to indicate when data has been upated and is valid. The Data

Ready pulse indicates that the data bus has been updated with new data and that

the signals on the bus are completely settled. Both Data Ready True (Rising

Edge Trigger, signal driven from ground to Voltage high) and Data Ready False

(Falling Edge Trigger, signal driven from Voltage high to ground) are provided.

When using Data Ready True, data should be read from the bus on the rising

edge of the signal, and when using Data Ready False, data should be read on

the falling edge. Either the leading edge or the active level of the signal can be

used to trigger a read by your interface.

Ringing on the line can occur if the cable is not properly terminated. This can

cause the data to be unstable during the time of the active edge of the data ready

signal. Allow for extra settling time if ringing occurs.

Signal Activity Data Valid On:

Data Ready (True) Active High Rising Edge

Data Ready (False) Active Low Falling Edge

Data is valid from the time that the Data Ready signal is asserted until the time

that the next data point is received from the gauge. This time varies depending

on the gauge’s Update Rate configuration setting. See the timing specifications

below for detailed timing information.

Update Rate T4 1-2000 ms

The Data Ready Pulse Width and the Update Rate parameters can be configured

with a serial command. See the RS-232 Configuration Commands section for

details.

Choosing the correct polarity of "Data Ready" is important. Improper polarity

choice can lead to data that appears to be noisy or has spikes or is completely

invalid since the data may not be stable when it is read. In most cases, choosing

the correct "Data Ready" polarity for the interface is made before consideration of

the "Data Bit" polarity. The polarity of the Data Bits may or may not have to be

inverted by ~I:AckMode before the input module reads the data correctly.

Data Request Mode

When the system is configured for Data Request mode, a "Data Request" signal

issued by the PLC/Control System is used to notify the I/O Module that new data

is requested by your interface. The following figure shows Data Request Mode,

indicating typical waveforms and listing the timing information necessary to use

this mode. "Data Request" is an optically isolated input and requires a pulse

supplied by your interface (5 to 24 volts DC).

Data Setup Time T5 300 µs (min.)

Data Ready Pulse Width T6 ReadyLn x 500µs

Note: T6 is set using the serial command “~I:ReadyLn=X”, where X is an integer.

Divide the desired pulse width by 500µs, and use this value for X. When

configured in the "Data Request" mode, any Data Request from either Length or

Velocity will cause all "Data Request" type system outputs to be updated. Data

will remain on the output until a new "Data Request" is received. Only a single

Data Request Line from either the Length/Elongation Connector or the Velocity

connector should be utilized.

Note: If the Data Ready pulse length is configured to be longer than the Data

Request Period (T6>T1), the Data Ready output will always be high, and erratic

data may be read from the interface. Make sure that you configure the Data

Ready Pulse Width to be half the Data Request Period or less.

Installation


Example: If data is required every 2 ms, the PLC should pulse the Data Request

signal every 2ms. The Data Ready Pulse Width should be configured to be less

than half the Data Request Period. Use the command ~I:ReadyLn=2 to configure

the Data Ready Pulse Width for approx 1ms.


Installation


Elongation/Synchronization

Multiple I/O Modules can be connected together for applications that require

measurement synchronization and calculation of length elongation/differential

speed. This is accomplished by interconnecting the I/O Modules’ SYNC ports,

which are located on the rear panel. The shortest user update rate is 2 ms when

calculating the elongation ratio. If 1 ms user update rate is selected in the gauge

the I/O Module will only update its outputs every 2 ms.

Master/Slave I/O Modules

I/O Modules can either be masters or slaves, depending on where they are

located in the system. The way that the I/O Modules’ SYNC ports are

interconnected determines their relationship. When measuring elongation

ratio/differential speed, the Master gauge is located before the first roller stand.

This gauge measures the lowest speed of all the gauges in the system. All the

other gauges in the system are Slaves. The Slaves’ measurements are

synchronized to the Master, and make all their measurements at the same time

as the Master.

See the drawing on the following page.


Installation

Parallel Data Output. This feature automatically switches the Length/Elongation

port to output Elongation Ratio/Differential Speed when available. The last gauge

in the system (#4 in this example) outputs its measured length, which is the final

product length.

Elongation Measurement System


Installation


Synchronization

The High Speed Pulse Output can be used to generate the Synchronization

signal needed to synchronize all gauges in the system. This is accomplished by

configuring the High Speed Pulse output in LaserTrak Software to output the

Synchronization signal. In this configuration the gauge will output the

Synchronization pulse in place of Phase B of the High Speed Pulse output. The

Synchronization signal will automatically be routed to the gauge connected to the

I/O module and it will also be routed to the Synchronization Out connector that

goes to the first slave in the system. Each Slave in the system will replicate the

Synchronization signal, sending the Synchronization signal to its gauge and

outputting it on its Synchronization out connector. All Slaves can be Daisy

chained in this fashion. To enable Synchronization in the LaserSpeed gauges, all

the High Speed Pulse Outputs should be configured to output the synchronization

signal. This can be done using LaserTrak, or by setting the $H configuration

setting to 9. While only the Master gauge truly needs to output this signal,

configuring all the gauges and I/O Modules the same way will allow the gauges

and/or I/O Modules to be interchangeable with spares or moved around the

system without having to reconfigure any gauge settings.

The I/O Module does not require configuration to enable

Synchronization/Elongation Measurement. This functionality is automatically

enabled when the I/O Module detects that a Synchronization cable has been

attached.


Installation


Elongation/Differential Speed Calculation

Slave I/O Modules automatically transmit their gauge’s measured velocity out of

the SYNC port to the I/O Module connected to the SYNC IN connector. The

connected I/O Module receives this velocity and calculates elongation using the

following formula:

( )

where:

V1 is the velocity of the slave gauge

V0 is the velocity of the master gauge (connected to the I/O Module that

is calculating elongation.

The figure above shows a typical elongation measurement system. The I/O

Modules are numbered 1-4, with #1 as the Master and #4 as the Last Slave. I/O

Modules 1-3 calculate elongation by:

Setup


Setup

The Setup Port can be used to set up the I/O Module and/or to set up the

LaserSpeed Gauge. Commands sent to the gauge are described in the

LaserSpeed Gauge Instruction Handbook. The I/O Module commands are

preceded by a ‘~’ character. A command preceded by a “.” instead of a “~” will

return the values comma delimited without the identifiers. The sequence is the

same as the ~ command.

Note: The voltage output for MaxVel is 2.048 volts, and the output voltage for

the MinVel is 0.0 volts. First enter the velocity for an output of 0.0 volts (MinVel),

and then enter the velocity for an output of 2.048 volts (MaxVel).

Data Format

The table below illustrates the value represented by each output bit. The value is

dependent upon the units of measure chosen in the processor configuration.

Units Length/Bit Velocity/Bit

Units Length Resolution Velocity Resolution

Feet/Min 0.001 ft/bit 0.001 ft/min/bit

Inches/Min 0.001 inches/bit 0.001 inches/min/bit

Meters/Sec 0.001 meters/bit 0.00001 m (10 m/sec/bit)

Meters/Min 0.001 meters/bit 0.001 m (1 mm/sec/bit)

The largest length that can be measured is 999,999.999 (meters, mm, feet,

yards, or inches). To output the decimal number as an integer, it is multiplied by

1000 to yield 999999999. To convert it back to a decimal number divide by 1000.

In hexadecimal notation, this number is 3B9AC9FF, which takes 30 bits to

represent. If the measured length exceeds this value, the output will remain

999999999. The maximum velocity, that can be measured, is 50,000.000

(meters/minute, mm/min, feet/minute or inches/second). To output the decimal

number as an integer, it is multiplied by 1000 to yield 50,000,000. To convert the

number back to decimal, divide by 1000. In hexadecimal notation this number is

2FAF080, which takes 26 bits to represent.

The resolution of the measurement increases to 5 places to the right of the

decimal point when the units of measurement are meters/second. In this case the

maximum velocity is 254.00000 meters/second. To output this decimal as an

integer, it is multiplied by 100,000 to yield 25,400,000 (18392C0 in hexadecimal).

This takes 25 bits to represent. To convert this number back to decimal, divide

by 100,000. Thus a length measurement requires 30 bits maximum for output

and a velocity measurement requires a maximum of 25 bits of value and 1 bit for

sign.

Setup


Serial Communications

The Setup port can be used to configure the I/O module and the LaserSpeed

gauge. Commands intended for the I/O module are preceded by a “~” and

commands intended for the LaserSpeed gauge are not preceded by the “~”.

When communicating to the LaserSpeed gauge via the Setup Port, the

commands are intercepted by the I/O module’s processor. The I/O module’s

processor checks for a “~” to determine if the command is intended for the I/O

module or the LaserSpeed gauge. If the command is preceded with a “~” the I/O

module will process the command. If the command is not preceded by a “~” the

command will be resent to the LaserSpeed gauge via a RS-422 Serial connection

between the I/O Module’s processor and the LaserSpeed gauge.

It is important to note that there are two communication links in the chain. The

first link is a RS-232 serial connection between the PLC or PC control computer

and the I/O module. The second link is a RS-422 serial connection between the

I/O Module and the LaserSpeed gauge. Each link has its own Baud Rate and

Framing Parameters. Both the RS-232 connection between the PLC or PC

control computer and the RS-422 connection between the I/O module and the

LaserSpeed gauge’s parameters have to be set correctly before the system will

function properly.

The most common mistake made is to set the RS-232 communication

parameters between the PLC or PC and the I/O module and not set the RS-422

communication parameters between the I/O module and the LaserSpeed gauge.

Set the RS-232 Baud Rate, number of data bits, parity, and number of stop bits

the same in the PC/PLC and the I/O Module.

Set the RS-422 Baud Rate, number of data bits, parity, and number of stop bits

the same in the I/O Module and the LaserSpeed gauge.

Note: When sending commands to the LaserSpeed gauge, the status, velocity,

and length output data will be temporarily stop while the gauge is operating on

the command. Data will be interrupted on the Ethernet, Profibus, Parallel I/O,

and Serial connections. Data transmission will automatically resume once the

gauge has acted on the command.

Setup


Default Communication Settings

The default communication Baud Rate and framing for the RS232 Setup Port is

115200 Baud Rate, 7 data bits, 2 stop bits, No Parity. Set the PC or PLC to this

Baud Rate and framing to begin communicating with the I/O module. Once you

have established communication with the I/O module you may change the Baud

Rate and framing to any Baud Rate and framing supported by the ~J command.

See section I/O Module Configuration Commands for details.

If you have trouble establishing communication with the I/O module at the default

setting, the Baud Rate and framing settings may have been changed. To

establish communications, Set the PC/PLC Baud Rate and framing to 115200, 8

data bits, 1 stop bit, No Parity and power the I/O module off, wait 60 seconds,

then power back on. On power up, the I/O module will output the following

message at 115200 Baud Rate, 8 data bits, 1 stop bit, No Parity:

I/O Module ready.

The I/O module will remain at 115200 Baud Rate, 8 data bits, 1 stop bit, no parity

if you send an R<CR> in the first 15 seconds after power up, If you do not send a

‘R’<CR> within 15 seconds after power up, the I/O module will switch the Baud

Rate and framing to what is was last time it was configured.

Once communication has been established between the PC/PLC and the I/O, all

the configuration parameters can be extracted from the I/O using the ~H

command. See section I/O Module Configuration Commands. Any or all

configuration parameters may be changed to suit the application requirements.

Where <N> is the velocity at which the Velocity Analog Output reaches its

maximum value of 2.048V. This value is normally positive, but can also be

negative. This value is scaled by 1000.

Example: Assuming Measurement Units are m/min, sending the command

~A:MaxVel=300000<CR> sets the full scale analog output of 2.048 volts to 300

m/min. When the measured velocity is > 300 m/min, the analog output will be

limited to the maximum output voltage of 2.048V.

Where <N> is the elongation ratio at which the Elongation Analog Output reaches

its maximum value of 2.048V. This value can be a positive or negative value, or

can be zero. This value is a percentage value that is scaled by 100.

Example: Sending the command ~A:MaxElg=500<CR> will set the elongation

full scale analog output to 2.048V for an elongation ratio of 5%. When the

elongation measurement is > 5%, the analog output will be limited to the

maximum output voltage of 2.048V.

This command configures the baud rate and framing for the RS-422

communication link between the I/O Module and the LaserSpeed gauge. These

settings must be set to match the gauge’s communication settings for

communication between the two devices to function. The valid baud rates are

listed in the table above.

Recommended settings:

Setup


The recommended settings will enable binary communication mode between the

gauge and the I/O module and allow for the fastest possible data throughput. If

you are using a different baud rate/framing configuration, you can change the

LaserSpeed gauge’s baud rate/framing to the recommended settings by sending

the command @11<CR> to the gauge. To set the I/O module to the same baud

rate/framing, sending the following command to the I/O Module:

~B230400,1,8,None<CR>.

Note: When synchronizing multiple gauges, the SyncMode setting should be set

to 1, and all gauges’ $H settings set to 9. This will allow the I/O Module to rely on

the gauge’s synchronization output timing for increased performance. This is

required when operating synchronized gauges with fast update rates.

Note: The gauge’s RS422 baud rate should be changed before changing this

setting (using the @ command), as changing the I/O Module’s baud rate will make

the I/O Module unable to communicate with the gauge if the two devices’ baud

rates no longer match.

Note: Communication between the I/O Module and the gauge can be check by

viewing the lights on the I/O Module’s front panel. If the lights are functioning

properly the gauge and the I/O module are communicating properly.

Note: The order for the baud rate/framing for the I/O module is:

Baud Rate, Stop Bits, Data Bits, Parity, not

Baud Rate, Data Bits, Stop Bits, Parity.

Setup


When Auto-Elongation Mode is enabled, and the I/O Module is measuring

elongation, the Length parallel output is replaced with Elongation. Since the last

slave in a chain of I/O Modules does not measure elongation, it always outputs

length. See the Elongation/Synchronization section for more information. When

the Auto-Elongation Mode is disabled, the Length/Elongation port will always

output length.

Example: To enable Auto-Elongation Mode, send the command

~I:Elongation=1<CR>. To disable Auto-Elongation Mode, send the command

~I:Elongation=0<CR>.

I/O Module Software P/N 93064 Rev E, Fri Nov 15 15:07:17 2013


Setup


I/O Module-to-LaserSpeed Communication

If the LaserSpeed baud rate/framing is different from the I/O Modules baud

rate/framing, the communication link between them will not work. Check the

lights on the front panel of the I/O Module to see it they are functioning properly.

The I/O Module-to-Gauge communication link is not working when the front panel

lights are not functioning properly. If the I/O Module is not communicating with

the gauge, check the flashing COMM lamp on the gauge during power up to

determine the baud rate. See the gauge handbook to determine the baud rate

from the flashing COMM Light. Set the I/O Module to match the gauge’s baud

rate.


Operation


Operation

Understanding the Front Panel

Front Panel Item Description

Key Switch The key switch is used to turn the LaserSpeed

Gauge’s laser on and off. The switch is connected in

series with the laser power jumper on the rear panel

on the connector labeled STATUS. The Key Switch

must be on, and the Interlock must be active to turn

on the Laser.

Interlock Indicator This indicator is lit when power is supplied to the

laser, indicating that the interlock is on.

Quality Indicator This indicator shows the signal quality to the

LaserSpeed Gauge. Green indicates “Ok”, yellow in

the middle region indicates “good”, and red in the

lower region indicates a bad signal.

Valid Measurement Light When lit, indicates that good measurements are

being received from the LaserSpeed.


Operation


Material Present Light When lit, indicates that material is present in front of

the LaserSpeed. ONLY USED WITH

LS9000/LS8000-2 GAUGES.

Laser at Temperature Light When lit, indicates that laser is at operational

temperature.

Laser Power Light When lit, indicates that power is applied to the laser

diode.

Shutter Open Light When lit, indicates that the laser gauge’s shutter is

open.

Note that all indicators are blank when there is no communication from the

LaserSpeed gauge.

Profibus Operation

The Profibus module is automatically detected.

Status indications are described in the LaserSpeed I/O Module Operator Guide.

Profibus Command Structure

Values are updated every time the LS9000/LS8000 is updated.

The Status/Command, Velocity, Length, Quality Factor, and Status information is

updated at the User update

Use 93434 I/O Module hms1003.gds file for setting up the profibus. This is

supplied on a CD with the I/O Module.

Rate specified by the LS9000/LS8000.

Note: When sending configuration parameters to the LS9000/LS8000, the

status, velocity and length transmission from the gauge is temporarily halted

while the LS9000/LS8000 is updating its configuration parameters. This will

interrupt data being output via the Ethernet, Profibus, Serial and Parallel I/O

ports.

Bit 7 Bit 6 Bit 5 Bit 4 Bit 3 Bit2 Bit 1 Bit 0

0 0 0 0 0 0 Retrieves data

LaserSpeed

Send Data to

LaserSpeed


Operation


To send configuration parameters to the LS9000/LS8000:

1) The Profibus Master sets all the configuration parameters in the DP

Slave

2) The Master sets Bit 0 of the Status & Command byte to a “1”. PUV = 1

3) The I/O Module sends all the configuration parameters to the

LaserSpeed gauge.

4) The I/O Module sets Masters PUV to 1.

5) Master detects PUV set to 1 and sets the I/O Module PUV to 0.

6) The PUV status Bit 1 is cleared in the PUV byte when the configuration

parameters have been updated in the gauge. Wait until Master PUV =

0.

The least significant 2 bits (LS-nibble) of the PUV Command Status Byte

determine the mode of operation of the I/O Module. The Fieldbus Master may

change any of the user bytes. A bit in the PUV signals when the data has

changed. A simple handshake scheme between the Fieldbus Master and the I/O

Module accomplish the configuration.

The Master writes appropriate data into the Output Data Block and then sets the

LS-nibble of its PUV Command Status to 0x01 (hexadecimal value) to begin the

initialization process. The I/O Module reads the PUV value every 100

milliseconds and begins a configuration sequence when the PUV = 0x01. The

I/O Module uses the data then writes 0x01 back to the Master’s PUV to signal the

transfer. The Master sets the PUV to 0x00. The configuration sequence ends with

the I/O Module setting its corresponding PUV Command Status byte to 0x00. The

Master reads this value as acknowledgment of the configuration. No other

configuration should ever be required until a setup change is desired.

To get existing setups:

1) The Master Sets 2nd

bit in the Status & Command to 1. PUV = 2

2) The I/O Module reads the PUV= 2, the I/O Module will get the

configuration parameters from the gauge and update the Master’s

Profibus memory.

3) The I/O Module sets Master PUV = 2

4) When the Master sees PUV=2, the Master can read the configuration

parameters.

5) Master sets PUV to 0.

When retrieving data from the LS9000/LS8000 gauge, data is first downloaded

from the gauge and then sent to the Profibus connection. This can take several

seconds.


Operation


To retrieve data, the least significant 2 bits (LS-nibble) of the PUV Command

Status Byte determine the mode of operation of the I/O Module. The data

corresponds to Output Data block. A simple handshake scheme between the

Fieldbus Master and the I/O Module accomplish configuration. The Master sets

the LS-nibble of its PUV Command Status to 0x02 (hexadecimal value) to begin

the initialization process. The I/O Module reads the PUV value at every 100

milliseconds and begins a configuration sequence when the PUV = 0x02. The

I/O Module gets the configuration parameters from the gauge and updates

Master’s Output Data block, then writes 0x02 back to the Master’s PUV to signal

start of transfer. The Master sets the PUV to 0x00. The configuration sequence

ends with the LaserSpeed setting its corresponding PUV byte to 0x00. The

Master then reads data.

Operation


Ethernet Network Operation

The Ethernet interface is automatically detected. The I/O Module’s interface

supports either T10 or T100. IP address and ports must be set up before use. A

dedicated peer-to-peer network is recommended due the high traffic rate of the

UDP broadcast when using a fast update rate.

Status indications are described in the LaserSpeed I/O Module Operator Guide.

IP Sets the Ethernet IP address of the I/O Module Default is

192.168.001.111

UdpIp Set the address the UDP will broadcast to. Should be the

IP of the Master.

UDP Port Port number for UDP broadcast. This is the port the

Master should use to receive data. Default = 4750

TCP port TCP port for sending and receiving setup data. Default =

4751

Gateway = 0.0.0.0

Mask = 255.255.255.000

UDP Data Broadcast

These values are updated every update period of the gauge and sent out by a

UDP broadcast to the IP at a port specified during setup.

Bytes Name Equivalent LS9000/LS8000 Command

4 Velocity Updated each User Update

4 Length Updated each User Update

1 Quality factor 0-15, 0 bad, 15 great

1 Status 1st bit gauge at temperature, 2nd bit laser on,

3rd bit shutter open, 4th bit valid measurement,

5th bit

Note: When sending configuration parameters to the LS9000/LS8000, the

velocity and length update from the gauge is temporarily halted while the

LS9000/LS8000 is updated to the new setup. This will interrupt data being sent

via the Ethernet connection.


Operation


TCP Setup

These values are sent and received by a TCP connection. The Status &

Command commands initiate the action.

1) To send new configuration parameters to the LS9000/LS8000

2) Change any setups in the Ethernet setting.

3) Send data to I/O Module using TCP.

4) Set 1st bit in Status & command to signal change.

5) The I/O Module checks for any differences in the Ethernet to what’s in

the LS9000/LS8000.

6) Any changed values are updated to the LS9000/LS8000.

7) Bit 1 is cleared in the Status & Command byte when the

LS9000/LS8000 is updated.

8) Status is sent back.

To get existing setups:

1) Set 2nd

bit in the Status & Command.

2) Send data to I/O Module using TCP.

3) The I/O Module will update the Ethernet memory and send it back to IP

in TCP.

4) 2nd

bit is cleared on the data sent back.

When retrieving data from the LS9000/LS8000 gauge, data is first downloaded

from the gauge and then sent to the Profibus connection. This can take several

seconds.
