1. Introduction

Manual updates

This manual is updated for the 101.1.0.0 program version. In this program is a web
server added which enables for the user to access the instrument using a PC running a
web browser. This manual can also be used for the previous program version
(101.0.0.0) where the only differences are the ‘Network Config.’ menu, the Instrument
restart functionality and the remote access part.

General

The G4 Instrument is a high performance multi channel force indicator intended for
industrial systems.
Its basic function is to convert the signals from strain gauge transducers to useful force
information. Transducer excitation is included as well as parameter controlled signal
processing, indication of output levels, error supervision and operation of optional
external equipment. The instrument can be equipped with up to 6 synchronized force
channels.

The instrument is modular and can be equipped with different types of I/O units to
match the demands in the specific applications. There are strain gauge transducer
interface modules, a digital input/output module, analog output modules.
Internal solid-state outputs in the instrument can be used for output functions from level
supervision or ‘In process’ indication, reporting the operating status of the G4
Instrument.

The CPU unit in the instrument has several communication interfaces. It has two serial
communication ports, an Ethernet port, an USB port and a fieldbus slot.
Several G4 Instruments can be controlled from a master computer or PLC.
Serial communication interfaces are RS-485 and RS-232 using Modbus RTU protocol.
The Ethernet interface is using Modbus TCP and the optional fieldbus interface uses
Profibus or DeviceNet.

It is possible to load new software into the instrument using the USB port.
All functions in the G4 Instrument are controlled by set-up parameters. Setting of

parameter values can be performed via a service panel with display and 4 keys
(VIEWPAN module).

The Rail mount instrument type is powered with 24 V DC. All input and output signals
are galvanically isolated from the power supply by operational insulation.

Functions

Measurement with strain gauge transducers.

Both excitation voltage and output signal are measured at the transducer to avoid
influence from voltage drop in the connection cable. Excitation to the transducer, from
the G4 Instrument is provided over separate wires.
A shielded 6-wire cable must be used to connect a distant transducer to the instrument.

A/D conversion.
The analog signals from the transducer are converted to digital form and filtered
to give an internal transducer signal with high resolution.

Calculation.
The transducer excitation and signal values are combined to form an internal
transducer signal, representing the load on the transducer. Influenced by calibration
data, this signal is converted to a digital measurement value, the force value, which
can be presented at the local display window and at external equipment.

Error supervision.
As long as the error supervision detects no error, the signal ‘In process’ is present
but if an error is detected, ‘In process’ will be off and a specific error message will be
displayed. ‘In process’ can be set to control any digital output. Note that there are
force channel specific and instrument specific error detection.

Levels.
32 level comparators in the instrument can be set to switch at defined signal levels with
any selected hysteresis added, meaning that the switch level can be different for
increasing and decreasing signal. It’s possible to set level switching delays. Output
signals from these comparators are available on the serial communication. The level
comparator outputs can also be set to control digital outputs from the instrument.

Communication.
The G4 Instrument utilizes the serial interface, Ethernet and a fieldbus interface for
communication with control computer. The serial interface consists of a RS-232
(COM1) connection and a RS-485/RS-422 (COM2) connection. COM2 can be used
with 2- or 4-wire connection.
Force values, web tension values, level status, error status etc. can be collected and
commands given through the communication interfaces. Modbus RTU protocol is used
for the serial interfaces and Modbus TCP for the Ethernet connection. For the optional
fieldbus interface Profibus or DeviceNet can be used.

Instrument modes.

In normal operation mode the G4 Instrument is presenting the measurement values on
the front panel (VIEWPAN) alphanumerical display. Values for one Function Block at a
time can be shown. During parameter set-up the instrument will continue normal
operation. However if hardware set-up parameters have been changed the instrument
will be restarted.
The operator will always be notified before the instrument is restarted.

Parameter setting.

In the instrument all operating functions are controlled by set-up parameters with
numerical values, string values, or pre-selected values from a list of alternatives.
Parameter set-up is performed by the keys at the service panel (VIEWPAN).

Presentation.

The instrument can present measured or calculated values, parameter settings etc.
at the front panel. An extensive system of menus gives the possibility to present
various information about the instrument. The VIEWPAN module can present one or
two values at a time.

Measured or calculated values, status of levels and so on, can be transferred to
external equipment via the different communication interfaces (some are optional).

3. Instrument Functionality

General

This chapter describes the functionality of the different parts of the force instrument.

Function Block

All measuring functions in the instrument are based on configurable function blocks.
A Function Block is used to calculate the force or web tension of one to four inputs and

the sums and differences if more than one input is used. With a four channel Function
Block there are intermediate sum of force/web tension values calculated (A + B and
C + D).

The Function Block type is selected with parameter ‘Func.BlockX Type’ (Hardware
Configuration menu) and the value of the parameter can be set to ‘Not In Use’,
‘1 Channel’, ‘2 Channel’ or ‘4 Channel’. The type is selected individually for each used
Function Block.

A measuring channel, i.e. a connection on a WF IN / WF IN2 or HS WF2 module,
should be assigned to each Function Block input. The inputs of a Function Block are
named Input A to input D. Note that each measuring channel can only be assigned to
one Function Block input. Inputs cannot be shared between Function Blocks. The
maximum number of measuring channels in an instrument is 8 if WF IN2 modules are
used and 4 if HS WF2 modules are used.

A Function Block input can also be set to ‘Not In Use’ which means that the actual
input value used is always 0. This can be useful when using three transducers in a
4 channel Function Block or for testing purposes.

In the menu Param. Set-up – Calibration –
Function Block 1 (- 8) are parameters for configuration and
calibration located. Only used Function Blocks are displayed in
the menu.

The calibration parameters shown in the figure is for Function
Block 1.

There are sets of calibration parameters for each force input.
Parameters named ‘1:A …..’ belongs to input A, parameters
named ‘1:B …..’ belongs to input B and so on.

Calibration must be done for separately for each input.
All other parameters (‘1: …..’) are common for the whole

Function Block.

In the instrument and throughout this manual are outputs from
Function Blocks used for Display, Analog Outputs, Levels,
Communication, etc. These Output Signals are explained in the
tables below. The actual value for each “Output” is depending
on the Function Block type. E.g. if the sum of inputs C and D, on
a 4 channel Function Block, should be monitored on an analog
output, Output 2 should be chosen as the source for the analog

Web Tension Mode

A Function Block can be configured for web tension measuring by setting set-up
parameter ‘X:Web T. Mode’ to On. In this case some of the force values will be
recalculated to a web tension value using the ‘X:Web T. Factor’ as shown below.

Web Tension Value = Force Value / Web Tension Factor
If the Force Values are correctly calibrated in the desired measuring direction then the

‘Web T. Factor’ shall be set to the length of the roller (machine width) to get correct
Web Tension values, e.g. N/m. In other cases the ‘Web T. Factor’ must be calculated
based on calibration direction, web tension measuring direction, roller length, etc.

The following table and figures explains the function and the values from a Function
Block in web tension mode.

4. Set-up

General

All operating functions in the G4 Instrument are controlled by parameters. The
parameter values are permanently stored in the instrument and will not be lost when
the unit is switched off. At delivery the parameters are factory-set to default values,
giving the instrument an initial standard function.

The actual setting of the parameter values can be read and edited during normal
measuring operation in sub menu ‘Parameter Set-up’.

Editing of parameter values can be performed using the alphanumeric display and keys
on the front panel of the VIEWPAN module. After editing hardware parameters the
instrument will be restarted.

In the instrument there are two levels of security locks provided to protect from
unauthorized access to instrument functions and editing of parameters and values. The
locks are opened by four-digit codes.

Warning: Changes done during editing of set-up parameters will affect the behavior of
the instrument immediately. The user must take all necessary precautions to prevent
any undesired effects in the process monitored or controlled by the G4 instrument or a
connected control system.

It is strongly recommended to activate the set-up lock in the instrument to prevent any
unauthorized changes of set-up parameters.

It’s a good practice to make a backup of the set-up after changes have been done. See
chapter ‘8 Maintenance’ for more information on backup and restore.

The ‘Parameter Set-up’ menu contain the following sub menus:
General: This parameter group controls the general functionality of the instrument.

Such as display language, display contrast, security, key functions and so on.
Hardware Configuration: Parameters used for configuring the instrument hardware.

Here parameters that are used for basic configuration, of the Function blocks, found.
Note that when the instrument is starting up it will check that the installed hardware is
compatible with the settings. If not an alarm will be issued.

Calibration: Parameters that affect the behavior of the eight possible Function Blocks
in the instrument. There are parameters for calibration type, calibration values, filter
settings etc. All Function Blocks are individually settable.

Communication: Sub menus are Serial Com, Ethernet and Fieldbus.
Serial Com sub menu content is parameters used to set-up COM1 (RS232) and COM2
(RS485) on the CPU module. Parameters are among others: com. port mode, baud
rate and data format. Ethernet sub menu content is parameters for Modbus TCP
configuration. Fieldbus sub menu content is configuration parameters related to
fieldbus communication such as address, baud rate and transmitted data setup.

Level Supervision: The instrument has 32 level supervisors that are configured from
this sub menu. Settings for each level are which Function Block that the individual level
is to monitor and which signal that shall be monitored from the selected Function Block.
Signals that can be monitored are Sum value, Difference value, Output 1 and so on.
The output function e.g. if the output shall be active above or below the set level is

Technical Manual

4-2

configured here. There are parameters for hystereses setting and level switching
delays.

Inputs: The use of the instruments digital inputs is set in this menu. Note that the
inputs are numbered 11 to 38. Inputs 11 to 18 corresponds to inputs on slot 1 I/O
module, 21 to 28 correspond to inputs on slot 2 I/O and so on. The actual number of
inputs depends on what type of I/O-module that is installed in the respective slots. A
DIO8 module has 8 inputs a WF IN2 module has 4 inputs while an AOUT1 or AOUT4
has no inputs. Inputs can be used for zeroing of Function Blocks.

Outputs: The outputs menu contains the settings controlling the function of each
output. Numbering is 11 to 38 for the I/O module outputs. See section ‘Inputs’ above on
how individual output numbers correspond to each I/O slot. Each output can be
assigned an output function: Level output status or ‘In Process’ status.

Analog Outputs: This menu controls the behavior of an AOUT4 or an AOUT1 Analog
output module. The output signal source (Function Block No and signal type) can be
selected. Also output type and range high/low is settable.

Operators interface

The DIN-rail type of instrument uses the service
panel (VIEWPAN) located in the I/O slot system of
the instrument as operator interface. It also
includes a 24 VDC power supply that supports the
complete instrument with power. The VIEWPAN
module occupies slots 4 to 6.

It is also possible to connect a standard USB
keyboard for PC to the USB connector
at the CPU module. The keyboard will work in
parallel with the keys on VIEWPAN and will make
it easier to handle the configuration of the
instrument, as it can be used as an input for digits
and characters.

The keyboard keys ' + ', ' - ', ' ↑ ' or 'Esc', and
'Enter' will correspond the VIEWPAN keys ' + ',
' - ', ' ↑ ' , and ' ↵ '.

Function key 'F11' on the keyboard can be used
to access the 'Main Menu'.

ViewPan module

G4 Multi Channel Force Instrument

5. Calibration

General

When measuring with the G4 Instrument, the transducer output signal,
corresponding to the transducer load, is converted to a force value. The
conversion is controlled by several parameters with values defined during
calibration of the individual Function Blocks.

The G4 Instrument supports two calibration types:

• Table calibration - entry of values from transducer data sheet(s) or entry of
recorded values from a previous calibration.
Table calibration can be performed without any transducers connected.

• Known force calibration - storing of measured transducer signals for known
forces.

Calibration can only be performed in menu:
‘Param. Set-up/Calibration/Function Block X.’

A ‘Set-up code’ or ‘Operator code’ may be demanded. Note that the
measured force value for the calibrated Function Block may be temporarily
incorrect during calibration.
A new calibration starts as a calibration type is selected.

To ensure the best possible measuring results, the mechanical installation must be
carried out with great care. If an input has several transducers connected in parallel,
they must have the same rated load and impedance. If transducers and fixed supports
are combined, the load must be evenly distributed on all supports.

Example of a detailed data and calibration sheet for

a transducer from Nobel Weighing Systems.

Technical Manual

5-2

If the G4 Instrument must be replaced, a table calibration of the replacement unit can
be performed, with recorded values from an earlier calibration.

To get the best accuracy, a ‘Known Force’ calibration with known force to at least
2/3 of the used range, should be performed.

All calibration parameters are found in the menus under ‘Function Block X’. The
parameters are described in chapter 4 Set-up.

Note that calibration must be done separately for each input of each Function Block in
the instrument.

A VIEWPAN instrument will display actual force value and transducer signal for each
used input when in menu ‘Calibration Function Block X’. Force and transducer signals
are shown ‘after’ the last parameter in the menu.

Common parameters

For both calibration types measurement unit and resolution for the force value must
be set. These parameters apply to all inputs (input A – D) for the current Function
Block. The parameters, among others, are found in menu ‘Function Block X’. This
section deals only with the calibration parameters.

X:Measurem. Unit

This parameter defines the unit used for the force value. The same unit will also be
used for related set-up parameters.

X:Resolution

This parameter defines decimal point position and resolution for the force value. The
decimal point position selected here will be used in set up, in the displayed force value
and in the force value sent to a printer or computer. Resolution is understood to mean
the smallest force change presented.

To ensure a stable force display, it is recommended that the input signal to the
instrument should exceed 0.2 µV / resolution increment.

Calibrating using datasheet

When calibrating with data given in the transducer data sheet the ‘Table calibration’
method should be used. Note that there are two different ways that the transducer
characteristics may be described in a data sheet. Choose the appropriate method
below.

There are parameters for each input that are used with the current configuration for the
Function Block being calibrated. Function Blocks can be 1 channel (Input A), 2 channel
(Input A - B) or 4 channel (Input A - D) type. Note that only input channel A parameters
are shown in the text below.

The transducer characteristics is given as two (or more) load / transducer output value
pairs:

X:A ValueCal. P1:
Enter first calibration point load value, expressed in the measurement unit, (usually
zero) in this parameter. The live load is displayed when the enter button is pressed.
Press the enter button a second time to enter the X:A ValueCal.P1 value.

X:A T.Signal P1:

Enter first calibration point transducer output value, in mV/V, in this parameter.
X:A ValueCal. P2:

Enter last calibration point load value, expressed in the measurement unit, (usually
nominal load) in this parameter. The live load is displayed when the enter button is
pressed. Press the enter button a second time to enter the X:A ValueCal.P2 value.

X:A T.Signal P2:

Enter last calibration point transducer output value, in mV/V, in this parameter.

The change of transducer output in mV/V is given for a load change, usually
corresponding to the transducer nominal load:

X:A ValueCal. P1:
Enter zero in this parameter. The live load is displayed when the enter button is
pressed. Press the enter button a second time to enter the X:A ValueCal.P1 value.

X:A T.Signal P1:

Enter zero in this parameter.
X:A ValueCal. P2:

Enter the given load value, expressed in the measurement unit, in this parameter. This
value is usually nominal load. The live load is displayed when the enter button is
pressed. Press the enter button a second time to enter the X:A ValueCal.P2 value.

X:A T.Signal P2:
Enter the datasheet mV/V value, corresponding to the given load change, in this
parameter. This value is often called Rated Output. See the example of ‘Data and
Calibration Sheet’ shown under section General in this chapter.

After entering the four parameters above the gradient of the force input is defined. Next
step is to zero the input:

X:A Set Zero
Set zero is useful only when the installation is finished. By the digit keys this value can
be set to zero, for an unloaded input, or to the force of the known load for a loaded
input. Note that unloaded means when the display should show zero.

The live load is displayed when the enter button is pressed. Press the enter button a
second time to edit the zeroing value.

Technical Manual

5-4

X:A Zero Offset
This parameter is used for entry of the recorded zero offset value from a previous
calibration. If a zeroing has been performed with parameter ‘Set zero’ above, the value
of parameter ‘Zero offset’ need not be changed.

Repeat the calibration for all inputs used in the current Function Block.

Using parameter values from a previous
calibration

When calibrating with data from a previous calibration the ‘Table calibration’ method
should be used. This is performed by entry of recorded force values and corresponding
transducer signal values into the instrument. The accuracy of the copying procedure is

0.005 %.
There are parameters for each input that are used with the current configuration for the

Function Block being calibrated. Function Blocks can be 1 channel (Input A), 2 channel
(Input A - B) or 4 channel (Input A - D) type. Note that only input channel A parameters
are shown in the text below.

X:A ValueCal.P1, X:A ValueCal.P2

These parameters are used for entry of recorded force values, expressed in
the measurement unit, from a previous calibration. The live load is displayed when the
enter button is pressed. Press the enter button a second time to enter the value.

X:A T.Signal P1, X:A T.Signal P2

These parameters are used for entry of recorded transducer signal values for
corresponding calibration points.

X:A Set Zero
Set zero is useful only when the installation is finished. By the digit keys this value can
be set to zero, for an unloaded input, or to the force of the known load for a loaded
input. Note that unloaded means when the display should show zero.

The live load is displayed when the enter button is pressed. Press the enter button a
second time to edit the zeroing value.

X:A Zero Offset
This parameter is used for entry of the recorded zero offset value from a previous
calibration. If a zeroing has been performed with parameter ‘Set zero’ above, the value
of parameter ‘Zero offset’ need not be changed.

IMPORTANT

Besides the Zero Offset parameter mentioned above there is also a zero correction
value for each input of the Function Block. The zero correction values are stored, in
non-volatile memory, when using the front panel Zero key or communication Zero
function.

The zero correction values are reset (set to zero) when starting a new calibration
procedure.

If the Zero key or the communication zeroing function have been used since the last
calibration, a new zeroing must be done either by using the Set Zero calibration
parameter described above or by using the front panel Zero function or the
communication Zero function.

G4 Multi Channel Force Instrument

5-5

The front panel Zero function and the communication Zero function will zero all inputs
of the Function Block.

The Set Zero parameter only zero the corresponding input and the user must repeat
zeroing for all configured inputs of the Function Block.

Calibration with known forces

When calibrating with known forces applied to the transducers the ‘Known Force
calibration’ method should be used. This is normally the most accurate calibration type.
The transducer signals are measured and automatically stored when the input is
loaded with known force. Calibration of the lowest point is normally performed with the
transducers unloaded (with only fixed tare applied).
The second point should be placed as high as possible. It is recommended to load with
at least 2/3 of the used range.

There are parameters for each input that are used with the current configuration for the
Function Block being calibrated. Function Blocks can be 1 channel (Input A), 2 channel
(Input A - B) or 4 channel (Input A - D) type. Note that only input channel A parameters
are shown in the text below.

X:A ValueCal.P1

This parameter defines the force for the lowest calibration point. Normally the
transducers should be unloaded and the parameter value set to 0 (zero). This force
value and the corresponding transducer signal value are automatically stored in the
instrument.

The live load is displayed when the enter button is pressed. Press the enter button a
second time to enter the X:A ValueCal.P1 value.

X:A ValueCal.P2

The transducers should be loaded with known forces. These parameters show the load
according to the previous calibration and the parameter values should be changed to
the value of the known forces. As a parameter value is stored, the instrument will also
store the corresponding transducer signal value for that calibration point.

The live load is displayed when the enter button is pressed. Press the enter button a
second time to enter the X:A ValueCal.P2 value.

X:A T.Signal P1, X:A T.Signal P2

These parameters contain the automatically stored transducer signal values for
the calibration points. The values cannot be edited.

X:A Set Zero
Set zero is useful only when the installation is finished. By the digit keys this value can
be set to zero, for an unloaded input, or to the force of the known load for a loaded
input. Note that unloaded means when the display should show zero.

The live load is displayed when the enter button is pressed. Press the enter button a
second time to edit the zeroing value.

X:A Zero Offset
For a ready installation this parameter shows the zero offset after zeroing, a value that
should not be edited.

6. Operation

General

This version of G4 instrument with strain gauge transducers is designed mainly for
force and web tension purposes. The measurement values are displayed at the front
panel, and can also be transmitted to a master computer/PLC.
The measurement values can also be presented as the output signal from an analog
output module.
Some functions in the instrument can be controlled by digital input signals, and digital
outputs from the instrument can be used to indicate actual status of instrument,
function blocks, levels and so on. The number of inputs and outputs may be expanded
by connection of additional I/O modules.

Power supply

The instrument is powered by 24 VDC and should not be turned off during weekends
and over-night. The instrument uses the 24VDC power supply in the VIEWPAN
module. Continuous power supply to electronics and transducers prevents moisture
condensation in the units.

Power-up sequence

As the G4 instrument is started it enters the Starting up state.
If any error is detected during power-up, the sequence stops and an error code

will be displayed. If the error is not fatal it will be possible to enter the menu system to
correct possible set-up errors.

If the detected error is fatal, it will only be possible to select restart unless the error is a
database file problem. If the start-up error is a database file error it will be possible to
select between deleting the database file, entering program upgrade or restart.
Deleting the database or upgrading the program (also upgrading to the present
program version) will result in a new database to be created which may make the
instrument usable again. Note that settings will be default after creating a new
database. If the fatal error persists please contact your supplier.

If no errors are detected, the instrument can enter normal operation (automatic
start-up), displaying actual force/web tension values.

If ‘Manual start-up’ is selected, the instrument enters the ‘Wait for start’ state,
displaying a message ‘Manual start, Push any key’. When the operator presses
any button the instrument will switch over to normal operation.

Technical Manual

6-2

Operating display

In the operating display it is possible to display
force/web tension information from one
function block at a time.

The upper display row shows the function
block number followed by the sum value (force
or web tension) and the unit.

If the selected function block is a two or four
channel function block then the second row
will display the difference value. No unit is
displayed for the difference value, but its unit
is the same as for the sum.

The ViewPan ‘+’ and ‘−’ keys are used to
toggle between the available function blocks.

By pressing the ‘↑’ key additional functions for
the selected function block are displayed.

The ViewPan ‘+’ and ‘−’ keys are used to
toggle between the available functions.

Pressing the ‘↑’ key will return to the operating
display for the actual function block.

Available functions are:

Zeroing: the text Zero is displayed
on the lower text row of the display
when zeroing function is available.

Levels: Showing and changing the
levels that are assigned to the
current function block. Not shown
unless levels are assigned to the
function block.

Pressing the ‘↵’ key when a function
text is displayed will activate that
function. Note that the settings will
affect available options/functions.

Security locks

In the G4 instrument two security locks are included to prevent unauthorised access to the
instrument via the panel keys. The locks can be activated by parameters in menu ‘Main
menu/Parameter set-up/General’.

The following requires a login password if the corresponding lock is on.
Changing instrument clock: Operator lock.
Changing Levels: Operator lock.
Changing set-up parameters: Set-up lock (Operator lock).
Entering/using Backup Menu: Set-up lock (Operator lock).
Entering/using Restore Menu: Set-up lock (Operator lock).
Entering/using Default Menu: Set-up lock (Operator lock).
Entering/using Program Upgrade Menu: Set-up lock (Operator lock).
Entering/using File handling Menu: Set-up lock (Operator lock).
Changing values in Diagnostics menus: Set-up lock (Operator lock).
Changing Network Config: Set-up lock (Operator lock).

Entering set-up code gives access also to operator locked functions. If only operator
lock is on, the operator code is required where set-up lock is specified above.

Unlocking of “Levels” editing from the main picture, is valid until you return to the main
picture.

Unlocking of any function under the Main Menu, is valid until you leave the Main Menu.
There is also a protection from local and remote users both changing parameters. See

chapter ‘Remote Access’ section ‘Remote / Local Access’ for more information.

Codes for the security locks

When a security lock is activated the operator must enter a four digit code to get
access to the protected area. By default the valid code for both locks is ‘1 9 3 7’ ,
but the locks are not activated.
In menu ‘Parameter Set-up’, sub menu ‘General’, parameters are available to activate
the locks and to change the default code to any four-digit code.

The code for the Operator lock can only open the Operator lock.
The code for the Set-up lock will open both Set-up lock and Operator lock.

Zero setting

A basic zero setting of the force of each individual input is performed as part of the
calibration for a function block. If changes to the equipment are made later a renewed
calibration, or at least the zero setting of a calibration, should be performed.

Correction of the zero value may be needed and can rapidly be performed. Pressing the
zeroing key sequence, see section ‘Operating display’, will set the forces of all used
input channels for the selected Function Block to zero (providing that the ZERO key is
enabled in the set-up).

Level supervision

The G4 instrument contains 32 supervision Levels that can be used to supervise
defined signals in the instrument. Digital outputs can be connected as outputs for the
Levels. The properties for each Level are configured by set-up parameters.

Functions for Level supervision are defined in menu ‘Param. Set-up’ by parameters in
the sub menus ‘Level Superv.’ and ‘Outputs’. See chapter Set-up.

‘Level X Source’

Set to ‘Not in use’ will disable level X.
Select the signal that should be supervised by level X.

‘Level X Mode’

This parameter selects if the level should supervise the absolute value of the signal.
Note that if ‘Absolute’ is selected and the set level is negative, the level will always be
active regardless off the actual value off the signal.

‘Level X F.Block

The parameter ‘Level X Function Block’ is set to the Function Block no (1 – 8) that the
supervision level shall supervise.

‘Level X Output’

Defines how a digital output, if connected to the Level, should operate.
The parameter can be set to make an output active when the signal is above
the Level, or when it is below the Level.

‘Level X Hyst.’

Defines the width of a hystereses range for the Level. The definition of a negative
hystereses range starts with a minus sign( - ).
Hystereses is an intentional difference between the switch levels for increasing
and decreasing signal level. One switch level is always at the defined Level. The other
switch level is at a higher level by positive hystereses, at a lower level
by negative hystereses. See figure.

‘Level X Up Del.’
Defines the Delay time for increasing signal. The level will switch when the supervised
value has been above Level X value during the set delay time. It is possible to use delay
and hystereses concurrently, but it is recommended to set the hystereses to zero when
the ‘Level X Up Del.’ is used.

‘Level X Dn.Del.’
Defines the Delay time for decreasing signal. The level will switch when the supervised
value has been below Level X value during the set delay time. It is possible to use delay
and hystereses concurrently, but it is recommended to set the hystereses to zero when
the ‘Level X Dn.Del.’ is used.

Level status
Actual status of the Levels (input signal above or below Level) can be read via
communication.
The level status includes the influence from hystereses and delays, but it does not show
the status of any digital outputs, connected to the Levels.

Use of inputs and outputs

Internal I/O’s are included on some of the I/O-modules that the G4 instrument can be
equipped with. Different module types have different number of inputs and outputs. A
DIO8 module have 8 inputs and 8 outputs while the force conversion modules
HS WF2, WF IN and WF IN2 each have 4 inputs and 2 outputs.
All input and output functions are controlled by set-up parameters in the instrument.

Digital inputs

The digital inputs can be used for remote operation of the instrument.

Digital outputs

The digital outputs can be used for control of external equipment and for indication of
instrument status.

Analog outputs

To produce analog outputs from the G4 instrument, a one channel AOUT1 or a four
channel AOUT4 module is used.

The analog output signal will represent a selected signal in the instrument in form of an
analog current or voltage signal. All analog output functions are defined by parameters
in sub menu ‘Analog outputs’, see chapter 4 ‘Set-up’.

G4 Multi Channel Force Instrument

6-7

Filter function

In the instrument the measured values are filtered according to the settings chosen by
the user during set-up. The filter settings can be selected from a wide range. This
means that the instrument can be configured from very stable indication to more fast
response but with less stable readings depending on the demands from the actual
application. Note that the same filter setting apply to all inputs (A – D) in a function
block.

The user must consider the effects of different settings on the application. Choosing a
lower update rate will generally speaking give a more stable reading and may be used
when an operator should make a visual reading of the measuring value. A faster
update rate is typically selected when the instrument is used for closed loop control or
data logging/recording of fast processes.

When using the measured value, as feedback in a closed loop system great care must
be taken when choosing the filter settings. The overall phase shift in the loop has a
crucial influence on the stability. The measuring filter and the analog output filter both
give a contribution to the total loop phase shift. If communication is used to acquire
measuring value from the instrument, the delays and update rate in the network or on
the serial communication line, must also be taken into account when designing a
closed loop system.

Filter characteristics.

The parameters ‘HSWF Update R.’ / ‘WFIN Update R.’ selects the update rate and filter
characteristics of the measuring value. HS WF2 and WF IN / WF IN2 modules have
different ranges of settings.

With the ‘WFIN Update R.’ parameter set to ‘300 Hz ++’ the update rate will be 300 Hz
(i.e. same as ‘300 Hz’) but the filter has been optimized for high bandwidth, and less
phase shift, rather than effective damping. This also applies to ‘HSWF Update R.’
parameter when set to ‘800 Hz ++’ (using 800 Hz update rate). In both these cases the
user must consider the risk of aliasing. Avoid using these high bandwidth settings
(800 Hz ++ / 300 Hz ++) if excessive noise exists.

The figures in the tables below include the influence of the analog output filtering set to
400 Hz filtering bandwidth. Setting the analog filter bandwidth to a lower value will
reduce the frequency values in the tables. See Analog output filter table below.

G4 Multi Channel Force Instrument

7-1

7. Communication

General

The G4 Instrument has two serial communication ports, one Ethernet port and an
optional fieldbus module.

The serial communication ports, the Ethernet port and the optional fieldbus
interface module are used for communication with a control unit.

Serial interface

The instrument is equipped with 2 serial communication ports: COM1, COM2.
COM1 is a RS-232 port and COM2 is a RS-485 port

The COM2 serial communication utilises RS-485 for 2-wire or 4-wire. RS-485 is an
interface working with differential voltages, giving a noise resistant transmission in
a network with several units and long distances. The host computer (master) must
have an asynchronous communication port for RS-485, or use a converter
for RS-232 to RS-485 conversion or USB to RS-485.

If 2-wire transmission is used, the control unit must be capable of data flow
direction control or utilise a converter for automatic data flow direction control.
When 4-wire transmission is used, no data flow direction control is needed.

When the RS-232 port is used it’s possible to communicate with one instrument directly
from a PC with a RS-232 port without using a converter.

Modbus RTU Slave

General

All the G4 units connected to the network can listen to what is transmitted in the
network, but only one unit at a time may transmit. A time-sharing principle is
needed to allow communication in both directions (half duplex).

All communication in the network must be initiated by the control unit (master).
When the instrument is working together with a master the instrument units are all
slaves, only allowed to reply to master commands. As the master has addressed a
command message to a specific slave unit, it listens for the reply during a specified
time, before sending next command message.

If the reply from a slave unit fails it may be due to:

• Mismatch in communication parameters. (baud rate, address, . . )

• More than one slave unit has been transmitting at the same time.

This can distort the reply message and make it impossible to decode.

See ‘7. Communication − Modbus protocol’ section for detailed information of
register numbering, register content definition, commands etc.

More information about Modbus RTU can be found at ‘www.modbus-ida.com’ and
many other places.

Technical Manual

7-2

Setup of Modbus RTU communication

• The instrument will as default be given the address 1. If more than one instrument is
used in a network, each G4 instrument must be given a unique address in
parameter ‘Modbus address’ (in ‘Param. Set-up’, menu ‘Communication’, sub menu
‘Serial Com.’).

• Set parameter ‘COMx:Mode’ to ‘Modbus slave’.

• Select correct baud rate and data format in parameter ‘COMx:Baudrate’ and

‘COMx:Data Format’.

• Select wanted type of float values in parameter ‘COMx:Float Form.’.

• When longer response times are needed, set ‘COMx:Min Reply T’ to a suitable

value.

Modbus TCP Slave

General

The Ethernet communication port can be used to communicate with the instrument
using the Modbus TCP protocol. The instrument is a Modbus TCP slave and will only
respond to incoming messages from a master.

See ‘7. Communication − Modbus protocol’ section for detailed information of
register numbering, register content definition, commands etc.

More information about Modbus TCP can be found at ‘www.modbus-ida.com’ and
many other places.

Setup of Modbus TCP Slave communication

• Network configuration (IP-address, netmask,….) must be done from menu
‘Network Config.’

• Enable the Modbus TCP Slave by setting parameter ‘Modbus TCP Slave’ to ‘On’ in
menu ‘Ethernet’.

• Select wanted type of float values in parameter ‘Float Format’ (in menu ‘Ethernet’).

For communication with a master computer (PLC) the Modbus protocol is used in
the instrument. The Modbus protocol is a standard protocol, used for master/slave
communication in the industry.

Information is transmitted in blocks of data to minimise polling and response time
delays. For example the error register, status register and sum register could be read
with one command to the instrument.

When a command that cannot be performed is sent, the instrument responds with
an exception code. For a better explanation of the error, a special command error
register could be read.

Depending on the type of the communicating equipment (the master), the commands in
the application programme (PLC programme, or pc programme) may be different from
type to type. However, if the master is not a Modicon PLC system, then the Modbus
implementation in the master must have some cross-reference function to transfer the
Modbus register and I/O bit numbering to the masters own register and
I/O bit numbering. All registers and coils described in this manual use the standard
Modbus (Modicon) register and I/O numbering.
See the master's own Modbus driver documentation for how the commands should be
activated in the master's application programme.

Most manufacturers of PLC systems and HMI and SCADA software can provide
Modbus drivers. Various Modbus drivers for development of Windows programs are
also available on the market.

More information about Modbus protocol can be found at ‘www.modbus-ida.com’ and
many other places.

General registers

The G4 instrument has a number of Modicon 'Holding Registers' (registers 4XXXX ... ).
The Modbus function 03 'Read Holding Registers' should be used to read these
registers and the Modbus function 05 'Preset Single Register' or 16 'Preset Multiple
Registers' should be used to write to the registers.
See section ‘Data representation’ for a description of the different data formats used.

Hint: To find out which of the float formats that should be used, read
the ‘Instrument type’ register (44000), which equals ‘4002’ for the instrument.

*/ The read value is always ‘zero’.

Important:
‘Sum’, ‘Difference’, ‘Output 1-8’ ‘Input A-D Force’ and ‘Input A-D Signal’ registers for a

function block are only valid when corresponding ‘Error code’ register equals 0.
Therefore it’s recommended to read the ‘Error code’ register together with these
registers.

This register holds the type of the instrument. For a G4 Multi Channel Force Instrument
this value is 4002.

Standard program major and minor version

This registers holds the major and minor version for a standard program.

Special program major and minor version

This registers holds the major and minor version for a special program. Both values are
0 for a standard program.

Serial number

This register holds the serial number of the instrument. The value 991000 means
99-1000. This can be used by the master to be sure that an instrument with a specific
serial number is used for a special process.

Command error

This register holds the error code when a command has been sent to the instrument.
A command that gives a 03 or 07 as exception will have an error code with a better
description of the problem in this register. Normally this register should contain ‘00’
which means no error. Error codes 0 to 255 are valid in this register.

Instrument state

This register contains the state of the G4 instrument unit.

Code Description

00 ‘Starting up’ state.

The instrument is starting up after a reset or power on.

01 ‘Wait for start’ state.

The instrument is waiting for a start command to go in process.

03 ‘Normal’ state.

There are no parameter errors in the system.

Note: Force/Web Tension value errors still indicates normal state.

04 ‘Error’ state.

An error has been detected during start up of the instrument.

05 ‘Fatal error’ state.

An error has been detected during start up of the instrument.
It’s not possible to enter any other state from here.

Instrument error

This register holds the overall error code for the instrument.
Normally this register should contain ‘00’ which means no error.

Instrument status

This register holds the overall status for the instrument
Bits set to 1 in this register have the following meaning:

Bit no Function Comment

0

Remote operation ‘1’ = On ‘0’ = Off

1

Program reset The bit is set each time the program starts, and

it indicates that volatile data is lost.
The bit is reset as Instrument status is read,

over serial communication (Modbus RTU) or
over Ethernet (Modbus TCP), for the first time
after reset/power-up. Note that the reply
contains the set bit if it was set.

Reading Instrument Status via Fieldbus interface
will not reset this bit. To reset this bit with
fieldbus interface a specific reset command
must be used.

Care must be taken if more than one interface is
used to communicate with the instrument and
the Program reset bit is to be used.

Function Block X: Error code

This register holds the first error code for a Function Block.
Normally this register should contain ‘000’ which means no error.
Error codes 000 to 255 and 000 to X255 are valid in this register, where X (1-4) indicates
which input channel (A-D) the three digit error code belongs to.

Function Block X: Status

Status for a Function Block.
Bits set to 1 in this register have the following meaning:

Bit no Function Comment

0

Input A faulty There are an error on Input A.

See ‘Block X: Error code’.

Function Block X: Sum

This register holds the sum value for a Function Block. The actual use of the sum
value varies with type of Function Block.

The value should not be read alone because the status and error codes are stored in
other registers. The value is only valid when the register ‘Function Block X:Error code’
equals 00.

Function Block X: Difference

This register holds the difference value for a Function Block. The actual use of the
sum value varies with type of Function Block.

The value should not be read alone because the status and error codes are stored in
other registers. The value is only valid when the register ‘Function Block X:Error code’
equals 00.

Function Block X: Output 1

This register holds the Output 1 value for a Function Block. The actual use of the
value varies with type of Function Block. If this output is not used 0 will be output.

The value should not be read alone because the status and error codes are stored in
other registers. The value is only valid when the register ‘Function Block X:Error code’
equals 00.

Function Block X: Output 2 – Output 8

See ‘Function Block X: Output 1’.

Function Block X: Input A Force

This register holds the Input A Force value for a Function Block. If this input is not
used 0 will be output.

The value should not be read alone because the status and error codes are stored in
other registers. The value is only valid when the register ‘Function Block X:Error code’
equals 00.

Function Block X: Input B Force – Input D Force

See ‘Function Block X: Input A Force’.

Function Block X: Input A signal (mV/V)

This register holds the Input A signal in mV/V for a Function Block. This register could
be used for fault finding in the system. If this input is not used 0 will be output.

The value should not be read alone because the status and error codes are stored in
other registers. The value is only valid when the register ‘Function Block X:Error code’
equals 00.
