1 General Description

1.1 What is BaseMenu

BaseMenu is a tool that, amongst other things, allows you to test the operation of the
NC, enter the parameters and update the CNC files.
The functions it carried out, which are described in this manual, are dedicated to those
who develop automations with Kvara systems or to technicians providing assistance for
customers.

1.1.1 Its functions

In detail, BaseMenu can carry out the following functions:

File Management

Shared Editor

Channel monitor

PLC Menu

Alarms list

IO Redir Editor

Allows files or folders to be copied to and from disks,
including floppy disks or NC disks.
This means that files can be transmitted or received to and
from the FLASH DISK or RAM DISK of the NC. The
firmware can also be upgraded with this tool.

This is the parameters editor of the NC.
This tool is used to configure the operation of the firmware,
to enter the parameters of the axes, the part program
processing channels, etc...

This tool allows the operator to select the operating mode of
each channel, to select the program to execute and to debug
the operation.
This mask displays all the diagnostic information concerning
the operation of work cycles and axes movements.

This is mainly used to load the PLC program of the NC (after
an update). It also gives low level diagnostic information that
can help Esa/Gv technicians sort out NC faults not due to
logic or configuration problems.

Contains the list of all the activated and no longer activated
alarms, thus allowing transitory emergency situations to be
checked.

This tool sets up the configuration of the local and remote
analog and digital I/O devices connected to the NC.

ASCII Editor

Autosetup

A detailed description of the functions is given in the following chapters or this
manual.

Esa/Gv 91752.GO.0.GB

This tool allows any text file to be modified or newly written,
particularly work programs, fixed cycles or sub-programs.

This function must be used with caution. It is used to re­program the firmware of the CNC. If this function is used
improperly or by unauthorized personnel, the CNC could be
damaged and its operation blocked.

1.1.2 Description of the graphic mask areas

The user interface mask is divided into five zones or areas, as shown in the figure:

Figure 1.1 – Screen division

ù #1: contains information about the machine status or operating status of the CNC

(e.g. BASIC MENU when the machine is powered, CHANNEL MONITOR in
the channel monitor menu, etc.).

ù #2: formed by three lines containing the messages and alarms. The position

(meaning line number) and colour describe the type of message displayed:

− the first line displays the physical emergencies;

− the second line displays the general alarms;

− the third line displays the PLC messages or PLC alarms.

ù #3: contains symbols (or icons). The icons, if visible, have the following meanings:

− key: indicates that a password has been entered;

− disk drive: indicates that the floppy disk drive is operating;

− reference: indicates that the sizing cycle has been executed.

91752.GO.0.GB Esa/Gv

GO General Description

ù #4: used to display information, for data entry and for other functions that allow

the machine to be used.

ù #5: this consists of eight + two graphic keys (boxes) that describe the function

associated at that moment, with the function keys. White graphic keys indicate that
the corresponding function keys are not used by the current session;

The two end keys have fixed functions. The one on the left shuts down the current

mask while the one on the right activates a menu from which the system functions
can be selected.

The remaining function keys, if pressed, activate the functions to which the text

refers.

3.2.4 File copying

To copy one file:

1) Select the window and the unit in which the file is to be copied.

2) Switch to the other window by means of the [TAB] key.

3) Select the unit containing the file to be copied.

4) Set the selection bar on the file to be copied.

5) Press [Copy].

To copy several files:

1) Select the window and the unit in which the files are to be copied.

2) Switch to the other window by means of the [TAB] key.

3) Select the unit containing the files to be copied.

4) Select the files to copy.

5) When all the files to copy have been selected, press [Copy].

If the destination disk already contains the file to be copied, it will be overwritten
without any warning.

3.2.5 Filtered selection and deselection

Another, very quick way to select files, is filtered selection. This selection mode allows
the operator to enter a selection criterion, such as selection of all the files with the
same extension for example.

To select files by means of the filtered selection mode:

1) Select the window and the unit in which the files are to be selected.

2) Press [Filtered selection].

3) Digitize the selection criterion in the window that appears (E.g.: *.bat ).

4) Press [ENTER] to confirm the selection or [ESC] to annul the selection.

At the end of these operations, all files that conform to the entered selection criterion
will be highlighted in blue.

The deselection procedure functions in the same way but obtains the opposite result,
i.e. it deselects the files that conform to the entered deselection criterion. If no file has
been selected, it will evidently be impossible to deselect any.

6 Channel monitor

6.1 Introduction

Channel monitor is a tool that allows the operation of each ISO channel configured to
be controlled and verified.
The information in this mask concerns a single channel.

Activation

Role of the PLC with
the Channel Monitor

Press the [Channel Monitor] key in the BASIC MENU status to access the
CHANNEL MONITOR mask.

Many of the functions described below are only activated if a PLC program that
implements them is being executed. The controls that the Channel Monitor supplies to
the relative channel transit via the PLC which may customize the information or will at
least copy it into the channel registers. If PLC scanning is not activated or the PLC
program does not implement all the available functions, then the Channel Monitor will
only operate in partial mode.

6.2 Graphic display

The channel monitor is divided into various areas as shown in the figure.

Figura 6.1 -

6.2

1) Number and name of current channel

2) Channel status

3) Status semaphore of the program. Only of significance if the selected mode is

4) Display of the string associated with a $ command in the part program.

5) Channel axes targets

6) Additional information about the axes

7) Status icons of each axis

8) List of activated G modal functions

9) List of activated M, T, D functions

10) Function control buttons

11) Target for fixed increases (significant when the channel is in the INC status)

12) Override value display

13) List of the program selected or being executed with current line indication.

Some of the functions modify the aspect of the graphic mask, but not in a significant
wa. Areas 8, 9, 10, 11 and 12 are overwritten by a table that lists the parametric values
and their contents.

6.3 Detailed description of the information displayed

A great deal of the information displayed in this mask can be published by the channel
interpreter or executor. The difference lies in the fact that display in phase with the
interpreter is asynchronous in relation to real execution while display in phase with the
executor is synchronous.
Display in phase with the executor is certainly more significant during the debugging
operation. However, it introduces generation of an instrumental code to synchronize
the display. This leads to a loss of efficiency of a sometimes significant entity. The
parameter that influences this type of operation is Display in phase with interpreter in
the NC Options table. If it is 0 , the display will be in phase with the executor; if it is 1,
the display will be in phase with the interpreter.
It is advisable to select 1 for this parameter at the end of the part program test phase,
i.e. when the machine must begin the customer’s production cycle. This parameter can
be modified at any moment. The NC need not be reset, since the parameter is acquired
whenever a part program is executed, i.e. display in phase with the executor can be
restored if assistance work is required.

6.3.1 Axes information

Areas [5], [6] and [7] contain information about the axes belonging to the channel.
This information must be interpreted per line through all the areas indicated.

Targets Area [5] contains the current axes targets. The values are displayed in millimeters or

inches, depending on the unit of measurement chosen.

91752.GO.0.GB Esa/Gv

GO Channel monitor

6.3

Additional
information

Follow error

DAC voltage

Area [6] contains additional information concerning the axis with which it is aligned.
The information to display in this area can be chosen from amongst the following
options:

ù Follow error Ess
ù DAC voltage V
ù Distance from target ds

To modify the type of information displayed, press the [Alt] + [V] keys and select the
information from the pull-down window proposed.

This information is given in millimeters or encoder pulses, depending on how a
machine parameter has been set up (Parameter set version in the General parameters
table. Enter 1 for values displayed in millimeters or 0 for values displayed in pulses..
Warning: this parameter influences various other axes parameters. It must therefore
not be used to solely select the unit of measurement of the follow error).
This information is useful when the dynamics of axes that must interpolate with each
other must be set up. Interpolation will be correct if, speed being equal, all the axes
that must interpolate with each other have an equal follow error.

This information indicates the voltage that the NC supplies to the indicated axis drive.
This value is equivalent to the one that can be measured with a multimeter on the
analog output channel of the axis.
Its values can be between 0 and 10 Volt, even though 10 Volts are normally never
measured as this would mean saturating both the DAC converter and the drive. The
maximum value given by the NC on the output depends on the drive set-up.

Distance from the
target

The icons Area [7] contains a series of icons that supply information about the status of each axis.

This information displays the distance the axis needs to cover in order to reach the
programmed point. When the axis has arrived and stops, the value is 0. The instant in
which the axis starts to position, the maximum value is displayed, i.e. equivalent to the
distance between the starting point and the point to reach.
In the JOG and REF status, the value displayed is not the distance from the target
(which is not known) but the distance covered from the beginning of the movement.

They are displayed in real time and provide important information about debugging.
All the possible icons that can be displayed are listed below. The display of one does
not exclude the others as several icons can be present at the same time in order to give
a compound status of each axis.

Symbol Description

EMERGENCY

The axis is in the emergency status.

AXIS STOPPED

Indicates that the axis is at a standstill. This information concerns the
theoretic position, i.e. minus follow error recovery.

AXIS NOT SIZED

The axis has not yet been sized, i.e. the zero search cycle (homing) has not
been carried out. This signal disappears at the end of the sizing cycle and
does not appear again until the NC is newly powered.

ZERO MARK

Signals that the czero mark is activated in the current axis position. This
icon is displayed on each encoder turn. However, in view of the brief
duration of the zero mark, this icon may not be visible at high speeds.

ADVANCEMENT BLOCK

Indicates that the advancement block is activated. In this case, the axis
cannot move even if requested to.

ON MOTOR

Indicates that the drive must be enabled for the axis (activation of ON­MOTOR).

CLOSED LOOP

The regulating ring is activated, thus the axis is controlled.

LOWER LIMIT

The lower software limit has been reached. The axis cannot move towards
negative targets, just towards positive ones.

UPPER LIMIT

The upper software limit has been reached. The axis cannot move towards
positive targets, just towards negative ones.

NEGATIVE DIRECTION

The axis is moving towards negative targets.

POSITIVE DIRECTION

The axis is moving towards positive targets.

AXIS CONTROLLED BY ISO

The axis is being managed by the CHANNEL and is thus controlled by an
ISO part program.

AXIS CONTROLLED BY PLC

The axis is managed by the PLC and is thus controlled by means of the
function blocks that govern movement via the PLC.

6.3.2 Information about the program status

The information listed below is determined by execution of a part program that causes
the change.

Modal functions Area [8] of the modal functions contains 10 groups where the activated G functions are

displayed. Each group contains the value of the last G programmed from amongst
those of the group that exclude each other.

Group 1 Movements G0 – G1 – G2 – G3
Group 2 Plane selection G17 – G18 - G19
Group 3 Tool corrector selection G40 – G41 – G42
Group 4 Workpiece origin selection G54 – G55 – G56 – G57
Group 5 Continuous mode selection G61 – G64
Group 6 Inches / millimeters G70 – G71
Group 7 incremental / absolute G90 – G91
Group 8 Selection of mode in which speeds are

expressed
Group 9 Rotation speed / constant cutting G96 – G97
Group 10 Fixed cycles

G93 – G94 – G95

G100 ⇒ G999

At the start, the default values are displayed while the currently used values will be
displayed during execution. A field without a value means that the group has no
default value and that none of the codes of that group have yet been executed.

Esa/Gv 91752.GO.0.GB

Channel monitor GO

6.6

Auxiliary functions Area [9] of the auxiliary functions contains 3 groups where the activated T, D, M

functions are displayed.
A field without a value means that the group has no default value and that none of the
codes of that group have yet been executed.

The last values programmed of each of the T, D and M functions are displayed in these
fields. The values of these functions are only overwritten when a new, homogeneous
function is executed.

Speed display Area [12] has two slide bars that give the percentage programming of the axes and

spindle override and the programmed speed value for both.
The slides have a 150% full scale (maximum override value accepted by the channel).
The bar indicates the set percentage.
The programmed speed is also displayed for both fields, concerning the axes (F) and
the spindle (S): in mm/min for the axes and in RPM for the spindle.
The speeds displayed are the programmed ones, thus with reference to a 100%
override.

6.3.3 The window of the selected program

Area [13] displays the list of the selected program.
The display activates when a valid program is selected.
The name of the selected program (or an error if the program is not found) appears in
the upper part of the window.
The program list is flanked by the displayed line number.

As soon as program execution begins, a yellow bar appears showing the currently
executed line. The displayed portion of program is automatically centered in a frame
around the current line so that this is always visible.

If the program is not being executed, the scroll bars of the window can be used to
display parts of the program that are not visible.

GO Channel monitor

6.7

6.4 Channel Monitor functions

The main channel monitor functions available are described below.

6.4.1 Required channel selection

The first thing to do when the channel monitor is activated is to select the number of
the channel required. When activated, the channel monitor proposes the first channel
configured (normally N° 0).
The selection is made by pressing the [Select Channel] key and digitizing the required
channel number.
Instead of entering the number, the selection can be made by entering the name
associated with the channel (if set in the channel parameters).
In this case, instead of digitizing the channel number, press [TAB] and enter the
required channel number. In both cases, confirm the selection with [ENTER].
If the number or name of the selected channel is not correct or not configured,
selection will have no effect.

6.4.2 Current axis selection

One of the axes may be highlighted in a different colour in area [5] of the channel
monitor mask, i.e. that of the axes targets. This is the current axis, i.e. the axis
subjected to the single axis JOG, INC or REF movements.
Use the [↓↓] [↑↑] keys to modify the axis selection. This action highlights the next or
previous axis.

This is a function that requires the intervention of the PLC. Whenever the above
mentioned keys are pressed, the channel monitor transmits a selection request to the
PLC which must be confirmed by this latter. Display occurs on confirmation from the
PLC. This mechanism allows an external selector that uses physical inputs to be
inserted for example. Since the PLC does not have to deal with the requests of the
channel monitor, it is thus able to write the value of the selector in the response
register, bypassing management of the arrow keys in favour of the external selector.
The PLC can also force any axis as current axis according to internal logics known to
the PLC programmer.
Axis selection behaviour is thus strongly influenced by the PLC program. So much so,
this latter could also stop the current axis from being displayed.

Current axis display is hidden by the channel monitor in the AUT and MDI statuses.

6.4.3 Channel status selection

Press the [Channel Status] key to select the channel status. A pull-down menu with a
complete list of the available statuses will appear:

ù REF Reference, axes zero search cycle
ù JOG Manual movement of the selected axis
ù INC Incremental movement of the selected axis
ù MDI Manual Data Input, execution of an entered ISO block
ù AUT Automatic, execution of the selected part program

Once a status has been selected, the channel is ready to receive commands pertaining
to the status activated.

Esa/Gv 91752.GO.0.GB

Channel monitor GO

6.8

REF status The PLC can activate the search cycle for the axes zeros. The cycle accomplished

depends on a machine parameter (Type of Sizing in the Axes Parameters table) which
establishes the sequence of the positionings made. A further parameter establishes the
direction of movement (Sizing direction reversal opt. in the Axes Parameters table),
while another two parameters define the speeds used (Micro search speed in siz. and
Mark search speed in siz. In the Axes Parameters table).
The REF cycle can be executed simultaneously for all the axes or with wired sequences
in the PLC logic.

JOG status The channel accepts axes movement commands in this status. The JOG movement

commands will probably be enabled by inputs that select the direction of movement.
Movement normally terminates by the input being released.
If the axis in movement has been sized, a JOG movement will never take the axis
beyond its limits. When these are neared, the NC begins its deceleration ramp even
though the movement input remains activated, and is thus able to stop on the exact
lower or upper limit of the axis.
Vice versa, if the axis has not been previously sized, its movement cannot be
controlled, thus the safety overtravel signals can be reached.
The speed used for these movements is expressed by a parameter that may differ for
each of the axes configured (Manual Speed in the Axes Parameters table).

INC status The operation of this status is almost the same as that of JOG. The only difference is

that axis positioning occurs from the current target of the selected axis onwards, for the
distance set in the area [11] (fixed increase). For example, if X axis is on target

255.000 and a forward increase with target INC=44 is requested, the axis will be
moved to 299.000.
The speed used for these movements is the maximum speed of the axis.

MDI status Selection of the MDI status allows a special program, the MDI program, to be executed

in automatic mode. Mode activation activates the [MDI] key that allows the ISO blocks
to be executed in this status to be inserted.

AUT status This status allows an ISO program to be executed. As usual, selection of the program

to execute is the task of the PLC. The contents of the selected program are displayed in
screen area [13].

91752.GO.0.GB Esa/Gv

GO Channel monitor

6.9

6.4.4 Movement in JOG mode

A single axis can be moved in the JOG status. Movement begins when the operator
presses a button and stops when this button is released.
There are normally two buttons, one for movement towards positive targets and one for
movement towards negative targets.

Activation First select the JOG status, then select the axis to move. After this, use the movement

buttons (depending on the PLC program) to move the selected axis in the positive or
negative direction.
The FORWARD and BACKWARD signals cannot be given at the same time.

6.4.5 Execution of a sizing cycle

Execution of a sizing cycle is of fundamental importance if the minimum and
maximum limits of the moving axes are to be used in full. A sizing cycle must be
executed whenever the CNC is powered.

Activation Select the REF status of the channel. Now press the sizing cycle button.

The axes sizing sequence is established by the PLC.

6.4.6 Positioning to incremental targets

Incremental movement is a status in which a positioning is carried out where the
distance to cover is known, to the detriment of the coordinate to reach.
The CNC calibrates the target of the selected axis and generates a positioning to target
increased (or decreased) by a programmed value.
Given DS as the programmed movement, Q0 as the current axis target and Qt the
required target, this latter is calculated in the following way:

Activation

Qt = Q0 + D

Qt = Q0 - D

Select the INC status and the axis to position. Now enter the positioning value (DS) by
pressing key [Inc. Target] and entering the required value in millimeters. Confirm
with [Enter].
Execution of a positive positioning is obtained by using the FORWARD movement
command provided by the PLC logic. Vice versa, a negative positioning is obtained by
using the BACKWARD movement command.
Release of the positioning key will not stop the axis which always terminates the
activated positioning, unless an emergency occurs.

6.4.7 JOG OPEN function

The JOG OPEN function allows the NC to be used as a reference signal generator for
drive sizing. In this status, the NC supplies a programmed voltage which is maintained
for as long as the signal remains activated. The wave shape generated includes the
acceleration and deceleration ramps.

Activation Select the JOG status and the axis to which JOG OPEN must be applied. Now press

the [Test] key. The [Jog Open] button is enabled in area [10]. It must be pressed. Now
enter the JOG OPEN voltage by pressing the [Jog Target] key. The value entered will
be expressed in Volts and must be within the 0 - 10 Volt range.
The commands provided by the PLC for JOG activation must now be used.

Consider that the command normally used for movements towards positive targets in
JOG mode leads to a positive voltage output. Vice versa, the command used for
movements towards negative targets leads to a negative voltage output.

The JOG OPEN voltage is maintained until the signal used for command execution is
released.

No checks on the axes limits are conducted in this status even when the axes have been
previously sized. It is the task of the person who works with the CNC to prevent
collisions on the axes hardware protections.

Deactivation

Press the [Jog Open] button again and then press [Test End] to deactivate the JOG
OPEN status.

6.4.8 Direct programming of an ISO block (MDI)

The MDI mode allows a program to be extemporaneously written and immediately
executed without having to quit the channel monitor.
CNC operation in this mode is the same as in the automatic mode.

Activation Select the MDI status. The aspect of area [13] changes and the displayed program

name becomes MDI.
Now press the [MDI] key, which is only enabled in this status. This action opens an
editor which proposes a blank sheet where the ISO instructions required can be
digitized.
There are no limitations in this programming phase in relation to normal
programming of a part program to execute in automatic mode.

When the ISO blocks have been written, press [Execute] and the newly created
program will appear in channel monitor area [13] just like a normal work program.
Press the machine button to start a normal work cycle.

Press the [MDI] key again to open the editor which will propose the previously written
program. This can be modified as required.

6.4.9 How to modify the current axis parameters

The parameters of an axis must often be modified during the set up phase. The channel
monitor allows a quick selection to be made for the table of parameters of each axis
associated with the channel without having to pass by the shared editor.
In actual fact, this function is a link with the shared editor which is called up by the
channel monitor in user-friendly mode and presents the parameters table of the
selected axis alone.
This function is only activated if one of the following statuses is selected:

ù JOG
ù REG
ù INC

It is not available in the AUT and MDI statuses. Moreover, an axis must be selected.
The function in question proposes the data of the currently selected axis.

Activation

In the presence of the conditions described above, press the [Test] key and then the
[Axes/Man Parameters] key. The mask containing all the selected axis data will be

created in the right-hand part of the channel monitor.
The required data can now be modified. Terminate this function by pressing [Monitor]
and then [Test End].
The entered parameters will now be activated. The axis uses the new values for the
next positionings.

6.5 Program execution

Program execution is strongly conditioned by PLC implementation. In some cases, this
latter assigns the number of the program to execute without taking the requests from
other entities into account. This is the case of channels that always use the same
program or programs whose selection is conditioned by the machine status.
In other cases, the User Interface dedicated to the application notifies the selection to
make by means of dedicated registers.
The Channel Monitor also notifies the selection of programs in dedicated registers. If
the PLC takes the information provided into consideration, it will then back the
function in question.

Activation

First select the AUT status, then select the program to execute by pressing the [Select
Program] key. The following file selection window will be proposed:

Figura 6.2 -

All the configured channels are listed. Any of the configured channels can be selected
by means of the selection window.
Select the check-box alongside the required channel then digit the names of the files to
execute for each of the selected channels.
The file to execute can also be selected by means of a disk browser by pressing the
[Scroll] button.

91752.GO.0.GB Esa/Gv6.12

GO Channel monitor

In particularly complex machines, the number of configured channels will exceed the
maximum number of channels that can be displayed in the window. In this case, use
the [Next] and [Previous] keys to scroll through the list of channels.
Once the operations have terminated, press [Ok], or [Cancel] to annul the selection
made.

The window of area [13] displays the first part of the program selected for the current
channel.

Execution Once selected, the program must be executed by means of the cycle start button, in

accordance with the PLC logic.

The semaphore The start of program execution turns on the GREEN light of the program. This

remains until execution ends, after which it goes out.
If the channel detects a programming error during execution, besides signaling the
occurrence by means of the alarms manager, it will also turn on the RED light of the
channel. This light will remain on until the PLC has reset channel operation.
The YELLOW light comes on after a HOLD request, i.e. when the axes are stopped in
their trajectory, and goes out after the work cycle has been reset.

6.5.1 Selection of the execution mode

Program execution can be influenced by certain execution modes:

ù Step-by-step execution Step
ù Barred block execution / Block
ù Dry Run execution Dry Run
ù Display of workpiece / machine origins Disp Loc
ù Syntactical correctness checks Verify

These modes are activated by pressing the dedicated button in area [10].
If the colour also changes after the key has been pressed, this means that the PLC has
acquired the request. Vice versa, the channel monitor will have transmitted the request
but the PLC will not have taken it into consideration and the selected function will not
have been activated.
Press the button again to disable the function.

Step This operating mode forces the channel to execute one line at a time, stopping the

execution while awaiting an enabling signal on each line. The PLC usually requires the
operator to press a button in order to execute the next instruction.
The step mode is used to verify the correctness of the program or to check the
trajectory of the programmed axes in order to avoid collisions with mechanical parts.
The step function is calibrated at the beginning of the cycle and is maintained for the
entire duration of the program execution cycle.

Barred Block The barred block execution mode allows ISO blocks to be written into a program and

to decide whether to execute it or not at the last moment without having to modify the
file.

Esa/Gv 91752.GO.0.GB 6.13

Channel monitor GO

The ISO blocks that have this property must be preceded by the “/” character. Enabling
of barred block execution includes all the blocks in question. Vice versa, blocks whose
first character is the bar will not be executed.
All the NON-BARRED blocks are executed in both modes.
The barred block execution command must be selected before the cycle begins and is
maintained for the entire cycle. It cannot be enabled or disabled whilst the cycle is
being executed.

DRY RUN This mode allows a program to be executed in verification mode. The axes are really

moved, but their speed is changed.
The speed used for the interpolations is the one defined by thye Speed F for dry-run
cycle in the Channel Parameters cycle. The speeds programmed in the cycle are
ignored. However, the functions that limit the speeds according to the Speed Control
Data parameters remain activated.
This function is complete if the PLC inhibits the activation of actuators that normally
help in the process, such as tools, coolant, exhausts, etc...

Loc Disp This mode allows the targets to be selected in relation to the machine origin or

workpiece origin.
If enabled, the display will refer to the workpiece, i.e. to the origin transfer
accomplished with the ISO G54 – G59 commands, otherwise the targets will refer to
the physical zero of each axis.
As origin transfer in ISO is only activated for the three main axes (X, Y e Z), thus
display selection will be of effect on these axes.
The Loc Disp. Mode can also be enabled or disabled during cycle execution.

Verify The Verify mode allows the correctness of the program to be verified before the cycle is

actually executed. When this mode is activated, the CNC will not produce axes
movements and will not require synchronisms with the PLC (codes M, S, T).
All the algorithms that check whether the program is correct (from syntactical checks
to axes limit checks) are, however, activated.
If a program executed in Verify mode terminates correctly, it can be executed without
expecting any execution errors. On the other hand, if an error is detected in Verify
mode, the Channel Monitor will synchronize area [13] to the program line that
contains the error.

6.5.2 Native variables display

Variables are often used to make calculations when ISO programs are created.
The channel monitor allows the value of these variables to be displayed and to thus
verify whether the calculations made in the program are correct.

Activation

Press the [Variables] key. Areas [8] [9] [10] [11] and [12] are replaced by the window
illustrated below.

91752.GO.0.GB Esa/Gv6.14

GO Channel monitor

Figura 6.3 -

The Local, Automatic and Globali variables can be displayed in this window.
On activation, the window proposes the list of local variables. Press [Automat.] to
display the automatic variables and then [Global] to display the global ones. Press
[Local] again to go back to the local variables displayed at the start. The key to press is
always the same as it is re-programmed each time with the function that allows access
to the next type of variables.

Press the [Mod/AUX Funct.] key to close the variables window.

After the variables window has been activated, use the arrow keys to select a variable.
Use the [Page Up] and [Page Down] keys to scroll through the pages of the table.
As will be noted, the current field is a different colour from the other fields.

Channel monitor GO

The value of a variable can be modified by making the right-hand part of the variable
line the current field and digitizing the required value.
Thus successive accesses to the program in reading mode will take the newly modified
variable value into account.

6.6 Debug

The DEBUG function allows total control to be taken of the tested ISO program, the
more critical parts of which can then be checked.
When the debugger is used, the operator can enter breakpoints, execute the program
step by step and thus check the consistency of the variables in a precise point of the
program as well as checking to make sure that the program flow is correct.

Area [13] is subjected to small graphic modifications so as to display information
concerning the execution flow of the program. For instance, an arrow is introduced
to indicate the current line while a round symbol indicates the programmed

interruption points (breakpoints).

Activation

Figura 6.4 -

Press the [Debug] key to activate the debugger. The graphic aspect of the channel
monitor remains unchanged. Just the functions of the keys change as they are re­defined in order to accomplish the debugging functions.

91752.GO.0.GB Esa/Gv6.16

GO Channel monitor

Deactivation

Press the [Debug End] key to terminate the debugging session and go back to the
normal Channel Monitor functions. This action cancels all the programmed
breakpoints.

6.6.1 BreakPoint

A breakpoint is an instruction that stops the execution cycle. To associate a breakpoint
with an instruction means asking for execution to be suspended as soon as the CNC
encounters that instruction. Once execution has been stopped, the channel monitor user
can interact with the program execution by removing or inserting breakpoints,
checking or modifying variables or requesting step-by-step execution.

How to insert a
breakpoint

Breakpoint removal To remove a breakpoint, use the same sequence as used to insert it. When pressed on a

To insert a breakpoint, first select the required line using the directional arrows. The
cursor of area [13] is positioned as a consequence. Once the line has been reached,
press the [Breakpoint] key. The breakpoint symbol will be displayed alongside the
number of the selected line to indicate that the interruption point is activated.

If the program flow is such that that line is not executed, the inserted breakpoint will
never be able to interrupt program execution.

level with a line with a programmed breakpoint, the [Breakpoint] key will remove the
actual breakpoint itself.
To remove all the breakpoints in the program without repeating the canceling
procedure for each individual breakpoint, simply use the [Remove All Breakpoints]
key which will cancel all the programmed breakpoints.

Esa/Gv 91752.GO.0.GB 6.17

Channel monitor GO

6.6.2 Step

Execution of a program in step mode is the same as entering a temporary breakpoint
on a level with the next instruction so that only the current line is executed, stopping
the execution on the next line.
Step-by-step execution of the program is obtained by means of input signals provided
by the PLC. This latter interfaces the step functions with the user.
The following step modes are tolerated:

Step Enables execution of the next program step. If a sub-program or

fixed cycle are encountered, they will be executed in atomic mode
without the debugger displaying the contents. This avoids
accessing the sub-program in debug mode.

Step In Same as Step, but if a sub-program or fixed cycle are encountered,

the next instruction executed is the first instruction of the sub­program. This means that step-by-step debug is executed within
the sub-program.

Step Out Executes the entire current sub-program code in atomic mode,

stopping on the first instruction after the current sub-program call.
This function is used to quit a sub-program and to continue with
step-by-step debugging in the calling program.

6.6.3 Display of symbolic variables

The debug function allows symbolic variables to be displayed, i.e. variables that require
a declaration in ISO mode.

Activation

This function is activated by pressing the [Watch] key. A window similar to the one
used to display the native variables is proposed.

8.1 Introduction

The tool described in this charter provides the basic functions allowing a PLC to be
loaded and operated. This tool is not a substitute for WBLOC. It is just a small and
simple tool to use if WBLOC is not available, or for less expert users since it is simpler
than WBLOC.

This tool also includes diagnostic functions.

Activation

Press the [PLC Menu] from the BASIC MENU status to access the PLC Menu.

8.2 CNC diagnostics

The window of the PLC Menu is used by the NC firmware to display low level
information that can be useful in order to identify a bad CNC configuration.
This information is used by the ESA/GV assistance service or other personnel with
considerable experience, fully familiar with the CNC.

Error display

How to delete the
error list

Press the [Display Errors] key and the list of errors present will appear in the vacant
space in the mask.
The messages that appear here represent diagnostic information that the firmware of
the NC publishes in order to diagnose the operation of the machine in a better way.
Some of the messages do not concern malfunctions but simply diagnose potentially
incorrect settings (they should be considered Warnings) while other messages identify
configuration errors.
The Esa/Gv assistance staff could ask to see this list in order to check out a CNC fault.

Press the [Cancel Errors] key to delete the displayed list of errors. This function is of
use when checking whether modifications made to the configuration after errors have
been displayed have been beneficial. By canceling the errors and repeating the display,
the assistance staff can check whether the errors have been resolved or not.

9 Autosetup

9.1 Introduction

The AUTOSETUP function allows all or part of the CNC firmware to be re­programmed.
This function may only be used by specialized personnel familiar with the exact
procedure and informed about the risk they can incur if it is not carried out in the
correct way.

The AUTOSETUP procedure is fully automatic and very safe. If it fails to be
completed for some reason, it will stop the CNC in such a way that can only be
repaired by Esa/Gv.
The main causes for an AUTOSETUP failure are:

ù Voltage drop
ù Interruption in the communication caused by the user

When to use
AUTOSETUP

− Opening of the connection between the NC and PC (e.g. Disconnection of the

serial link)

− If the NC or PC are switched off

− Intentional forced interruption of BaseMenu

There are no other causes that can block an AUTOSETUP.

This is why it is strongly inadvisable to inexpert persons to carry out this procedure.

AUTOSETUP must be used when a CNC must be upgraded with a new version or
when specified by the Esa/Gv assistance service.
The end user of the machine need never carry out an AUTOSETUP.

Before beginning the Autosetup process, the starting point in the sequence can be
selected by moving the cursor (line in reverse) with the arrows to the first step to
execute.

Steps can also be excluded from the sequence, after which the operations required will
be displayed with these steps cancelled. This can help carry out a more reliable
AUTOSETUP sequence. The option can be selected by customizing the Autosetup.ini
file.

next time, BaseMenu starts in normal mode and BaseMenu closes automatically.
Press the [Close] button to bypass execution of the Autosetup sequence.

Interruption of
Autosetup

Once Autosetup has started, it cannot be interrupted. Forced interruption (using the
Windows Task Manager) is one of the main causes of damage to the NC. Thus, if
Autosetup is launched accidentally, it is advisable to allow it to terminate.
