The
components described below are provided as part of ExceLINX-1A.
ExceLINX
is a Microsoft Excel add-in for the 2700, 2701, and 2750 systems. Within
minutes of installing ExceLINX-1A on a PC, users can acquire data dynamically
within Excel, then employ the familiar Excel graphics, charting, and analysis
capabilities. No Programming is required to use ExceLINX - a few mouse clicks
are all it takes to configure channels, set parameters, triggers, scan lists,
etc.
ExceLINX
uses the KE2700 IVI driver and the Keithley I/O layer (VISA) to communicate
with your instrument. IVI (Interchangeable Virtual Instruments) and VISA
(Virtual Instrument Software Architecture) provide a common foundation for
application development across multiple communication buses and multiple
instrument vendors. This software
driver supports many Application Development Environments under Windows, such
as Visual Basic, C/C++, LabView,
LabWindows CVI, and TestPoint.
Numerous
examples and an on-line help utility are provided to help programmers build
their custom applications. A shortcut
for the driver help is added to the Keithley Instruments folder on your Start
Menu.
The
Keithley Configuration Panel is provided to allow you to setup or modify the
communications between ExceLINX and your instrument. Before using ExceLINX or
the Driver, an instrument configuration must exist in the VISA software. This
installation pre-configures instruments for Serial ports COM1 and COM2, and for
a GPIB instrument at GPIB address 16. If you are using one of these, you may
skip the configuration panel. Otherwise, you must create a new instrument
configuration using the Keithley
Configuration Panel and Wizard. See instructions below. A shortcut for
the Configuration Panel is added to the Keithley Instruments folder on your
Start Menu. The configuration wizard
starts automatically when you run the configuration panel.
Version
C02 is a maintenance release that fixes several problems discovered in version
C01. The following issues have been
corrected in version C02.
ExceLINX
now installs properly in all supported foreign language versions of
Windows. See section 2 for system
requirements.
Relative
and absolute time stamps now work properly under foreign language versions of
Windows.
The Read
Task now works properly under foreign versions of Windows.
Several
miscellaneous installation and un-installation issues have been corrected.
TestPoint
Runtime is an executable start-up application written in TestPoint, an
Application Development Environment for Windows. TestPoint Runtime is an
easy-to-use point and click application that demonstrates the most commonly
used features of the 2700, 2701, and 2750 systems. Source code for Runtime is
also provided so you can purchase TestPoint and modify or extend the
application to meet your specific needs. The TestPoint Runtime software is
provided free of charge with every 2700, 2701, and 2750 Instrument.
TestPoint
Professional Development System is a complete package for creating test &
measurement applications, including support for GPIB and serial instruments,
control, math, graphing, A/D and many more features. TestPoint uses
object-oriented, drag-and-drop technology to bring both power and simplicity to
data acquisition and test & measurement. TestPoint offers three optional
toolkits that can be added to the base version: Internet Toolkit, Database
Toolkit, and Statistical Process Control (SPC) Toolkit. TestPoint is sold separately.

If you
will be using GPIB to communicate with your instrument, you must have a
compatible GPIB controller card and associated software driver installed in
your computer before installing ExceLINX
ExceLINX
is compatible with the following GPIB controller cards:
Keithley Instruments GPIB cards
(ISA, PCI, PCMCIA)
CEC GPIB cards (ISA, PCI)
National Instruments GPIB cards
(ISA, PCI, PCMCIA)
INES GPIB cards (PCMCIA)
When using
Keithley Instruments or CEC ISA or PCI GPIB cards, you must have driver
software version 5.14 or later. The
latest driver for these cards is available from the CEC WEB site: www.cec488.com.
Follow the
manufacturer's instructions for installing the controller card and software,
and for verifying correct operation of the card and software driver.
When
installing the INES driver software, do NOT install the HP I/O libraries or
select HP SICL emulation.
When
installing the INES driver software, DO select NI compatibility mode.
When
installing the INES driver software, if the hardware test fails, change the
Interrupt selection to none.
Connect
your Keithley 2700 or 2750 to your computer using a standard GPIB interface
cable or a "straight through" (not null-modem) serial RS-232 cable.
For 2701
Ethernet Connections, refer to the quick start guide that is provided with the
instrument.
If you
have an earlier version of ExceLINX software installed on your computer, and
you will be installing the new version from the CD, you should uninstall the
previous version by following the steps below before installing this version.
If you
will be installing an update downloaded via the Web, see section 4.4.2 below.
Using the
Add/Remove Programs Wizard in Control Panel, uninstall ExceLINX, the KE2700
Driver, and the Keithley I/O Layer. If
you have an entry in the Add/Remove Programs list for NI-VISA x.x.x Runtime,
uninstall that as well.
Reboot
your computer.
If you
have an earlier version of ExceLINX software installed on your computer, and
you will be installing the new version from the CD, you should uninstall the
previous version by following the steps below before installing this version.
Using the
Add/Remove Programs Wizard in Control Panel, uninstall ExceLINX, the KE2700
Driver, and the Keithley I/O Layer. If
you have an entry in the Add/Remove Programs list for NI-VISA x.x.x Runtime,
uninstall that as well. Now, reboot
your computer.
Insert the
ExceLINX CD in your computer. The
installation utility should start automatically. If it does not start automatically, run the install.exe file in
the root directory of the CD.
Follow the
instructions on the screen to install the software.
Note:
during the early part of the installation, the installation utility may appear
to stop for a minute or so. This is
normal and the utility will continue running in a short while.
When the
installation is complete, reboot your computer.
It is
recommended that you check www.keithley.com to see if there are any available updates to
the software.
If you are
a licensed user of a previous version of the ExceLINX Software you may download
an upgrade from www.keithley.com. The
upgrade will only install if ExceLINX is already installed on your computer. If
you do not have ExceLINX installed on your computer, you must install it from
the CD before you can install an update from the Web.
Download
the software from the Keithley Web site, www.keithley.com. The software is a single compressed file,
approximately 24 MB in size, and should be downloaded to a temporary directory.
Run the
downloaded file from the temporary directory.
Follow the
instructions on the screen to install the software. Note: during the early part
of the installation, the installation utility may appear to stop for a minute
or so. This is normal and the utility
will continue running in a short while.
Reboot
your computer during installation if so instructed by the installation utility.
When the
installation is complete, reboot your computer.
Installing
ExceLINX automatically also installs the KE2700 IVI driver. If you wish to install only the driver and
not ExceLINX, run the setup.exe file in the KE2700 subdirectory of the CD.
Before
ExceLINX can communicate with your instrument, an instrument configuration must
exist in the VISA software. ExceLINX
pre-configures instruments for Serial ports 1 and 2, and for a GPIB instrument
at GPIB address 16. If you are using
one of these, you may skip the rest of this step.
Otherwise,
you must create a new instrument configuration using the Keithley Configuration
Wizard. Open the Wizard by selecting Start>Programs>Keithley
Instruments>Keithley Configuration Panel, and wait for the Wizard to
start. Follow the Wizard instructions
to create a new configuration or modify an existing one.
A) Make
certain your instrument is properly connected to your instrument as described
above.
B) Power
on your Keithley 2700, 2701, or 2750
C) Make
sure the proper communications type (GPIB, Ethernet, or Serial RS-232) is
selected via the front panel of your Instrument.
Refer to
ExceLINX help if necessary to perform the following tasks. ExceLINX help may be accessed via the
ExceLINX menu in Excel.
A) Start
Excel.
B) Create
a new Configuration task and a new Scan task.
C) On the
Configuration Task page, in the Device field, select the device corresponding
to your instrument. Use KE2700_COM1 if your instrument is connected to the
first serial port or KE2700_COM2 for the second serial port. There are three default device
configurations for GPIB. All three are
for an instrument at GPIB address 16, if your instrument is not at address 16,
you will need to create a new or modify one of the default configurations as
described above.
If you are using a National
Instruments GPIB card, select KE2700_GPIB16 (or
KE2700_GPIB0_16) as your device.
If you are using a Keithley
Instruments or CEC ISA or PCI GPIB
card, select
KE2700_GPIB1_16 as your device.
If you are using a Keithley
Instrument or INES PCMCIA GPIB card, select
KE2700_GPIB2_16 as your device.
There is
no default device configuration for Ethernet.
If you are using an Ethernet connection to a 2701, you must create a
device configuration using the Keithley configuration panel and wizard as described
above.
D) From
the ExceLINX menu, select DMMConfig and then Detect Device. If your communications connection is
properly configured and working, ExceLINX will display information about the
switching modules installed in your instrument on the Configuration Task
Page. You are now ready to begin using
ExceLINX.
When you
run an ExceLINX task, the status of the command and any error messages that are
returned are displayed in the Status/Cmds field of each ExceLINX task spreadsheet. If the message is truncated because of the
limited size of the Status/Cmds field, click on the field to select it. The entire text of the message may now be
viewed in the Excel edit bar at the top of the spreadsheet. Error messages are displayed in red, while
normal status messages are displayed in black.
If you
enter an invalid value into an ExceLINX field, ExceLINX will change the invalid
value's color to red. Invalid entries
do not prevent the task from executing, but the invalid value is not sent to
the instrument. To rectify an invalid
value, change the value to a valid value, and click on any other cell to
trigger the validation logic.
Note,
because some values are related or interact, it is possible for a value in one
cell to cause other cells to be marked invalid. If cells marked in red appear to be correct, examine other
related cells for correct values. (PR16035, 15612, 15933, 19201, 15516)
ExceLINX
provides a toolbar for executing commonly used functions. The toolbar may be left floating or docked
similar to any other Excel toolbar.
Refer to Excel help for details on displaying, hiding, docking or
un-docking the toolbar.
When using
the toolbar, you must first select an ExceLINX task in the list box on the left
end of the toolbar. Once you have
selected a task in the list, the applicable toolbar buttons will be
enabled. All commands issued using the
toolbar apply only to the task selected in the list box.
In the
Instrument section of the configuration task spreadsheet, there are five fields
for display of the switching module type.
The first two fields are valid for 2700 and 2750, the remaining three
fields only apply to 2750s.
When a new
configuration spreadsheet is created, the Slot 1 and Slot 2 fields will display
"Undetected", while Slot 3-5 are blank. ExceLINX assumes you are using a 2700 until you actually
communicate with the instrument. To
populate these fields with the actual module types present in the instrument,
select the proper device in the device field, and then execute the Detect
Device command from the toolbar or the ExceLINX menu.
After
performing the Detect Device function, the Slot fields will list the model
number of the module present in that slot.
If there is no module in the slot, "Empty" will be
displayed. A blank field indicates that
that slot is not present on your instrument. (PR15607, 15893)
When using
ExceLINX to configure and operate your instrument, you should not use the
instrument's front panel to view or modify configuration. ExceLINX does not determine when changes
have been made on the front panel, and incorrect operation can result.
Furthermore,
ExceLINX does not send all configuration information to the instrument every
time a configuration task is executed.
Only items that have been changed within ExceLINX since the last time
the configuration task was run are written to the instrument. This means that if the instrument is turned
off or settings are changed from the front panel while ExceLINX is in use, the
instrument may become configured incorrectly.
To avoid this problem, avoid turning the instrument off or using the
front panel while ExceLINX is in use. (PR15996)
To make it
easier to prevent inadvertent changes via the front panel, ExceLINX can
optionally lock out the front panel when ExceLINX is using the instrument. This is controlled using the Front Panel
Lockout field on the Configuration task.
By default, Front Panel Lockout is set to on, meaning the front panel is
locked out while ExceLINX is using the instrument.
When Front
Panel Lockout is set to on, the front panel will be locked out the first time
ExceLINX access the instrument. To
release the front panel lockout, close Excel.
The first
time a scan task is executed, it automatically executes the associated
configure task. If no configuration
data is changed, the configuration task may not be executed on subsequent runs
of the scan task. The configuration
task can always be run by itself to configure the instrument without executing
any measurements. See also the note in
the known issues section of this document regarding configuration data caching.
Although,
for convenience, ExceLINX allows you to display data on the scan or read task
work sheets, it is recommended that you configure the tasks to place the data
on a separate spreadsheet. Because the
ExceLINX cells are protected from revisions and format changes, and because
Excel protects the entire column not just certain cells, you cannot alter the
format of cells on the task worksheets.
This means that date information can be displayed in an undesired format. Furthermore, when cells are first used to
display one type of information, such as a date, and then a different type of
data, such as a reading, the format will be incorrect, and the protection
prevents altering it to the desired setting.
By always
placing data on a separate work sheet, all these problems are avoided.
(PR15733)
If your
2701 loses power while in use by ExceLINX, or if the Ethernet connection is
interrupted, you must close and reopen Excel to reestablish the network
connection.
ExceLINX
uses the KE2700 IVI Instrument driver for communication with the
instrument. IVI drivers support several
features and functions that can improve performance and error checking. Advanced users can access these settings
using the Keithley Configuration Panel.
Several important advanced features are described below.
If this
feature is enabled the driver will query the instrument after every function
call to see if there where any errors. This is useful while you are writing
your application but once it is finalized then you can disable this feature to
gain extra performance.
If enabled
the IVI engine will check to see if the parameters you are passing in are within
range. Disabling this feature in the final application will also gain some
performance increase.
The driver
has the option of caching all the settings it sends to the instrument so that
it doesn't send a setting to the instrument a second time if it hasn't changed.
By default this is enabled.
In certain
circumstances, when an out-of-range value is specified on the configuration
task sheet, the instrument will not be configured properly. With a few exceptions described elsewhere in
this document, ExceLINX marks out of range values by showing them in red. Correct any red settings before running an
ExceLINX task. (PR19717, 16035)
Excel
worksheets are limited to a maximum of 256 columns and 65536 rows. It is possible with certain combinations of
settings for ExceLINX to overflow one or both of these limitations. The current version of ExceLINX may
overwrite data or may not record some data points if these limits are exceeded.
Make certain that the combination of settings you select for Scan list length,
reading count, Display location, and Data organization, and auto wrap will
allow all your data to fit on a single sheet.
If you must collect more data than will fit on a single Excel worksheet,
you may turn on logging to a file. When
file logging is enabled, all data is written to the file, regardless of whether
or not it fits on a worksheet. If more
data is logged than can fit on the worksheet, the message "Not all data
displayed" will appear in the status area.
In
addition to the limits described above for spreadsheet size, Excel can run out
of memory if you attempt to create a very large spreadsheet with all the cells
containing data. Excel will run very
slowly or generate error messages if it begins to run out of memory. The point
at which this happens is dependent on the amount of primary and virtual memory
available on your computer. (PR15897, 15991)
ExceLINX
maintains a data location pointer so it knows where to write the next data item
read back from the instrument. When a task is executed for the first time, the
pointer is set to the value specified in the Starting Row and Starting Column
fields. After each data item is stored
in the spreadsheet, the pointer is incremented one row or column depending as
required by the Organize by rows or Organize by columns setting and other
factors.
You can
manually reset the pointer to the initial settings using the Reset Data
Location function on the toolbar or ExceLINX menu.
However,
changing any of the settings in the Data Location or Data Display sections of
the Scan Task may reset the Data Location pointer to its initial value. This means that the next time the scan task
is run, it will begin writing data in the cell specified by the Starting Row
and Starting Column parameters. This can overwrite any data that might have
been previously written to that location.
Changing the list of channels to be scanned by modifying the channel
list in the configuration task can also cause this problem.
To avoid
this problem, it is recommended that you use a trial run to make sure you have
the proper channels configured and the Data Location and Data Display
parameters adjusted to your desired settings. Then clear the trial run data
using the ExceLINX erase function or Excel's clear contents function. Finally, reset the data location to its
initial setting using the Reset Data Location function, You can now run the scan task to acquire
data. (PR15988, 14738, 15898, 15764)
ExceLINX
will not work properly if you have change tracking enabled. Do not enable Excel Change Tracking when using the ExceLINX software. (PR18991)
The
current version of ExceLINX will not write data to column IV or row 65536. Adjust data location settings to avoid
writing data into those cells. (PR16105)
The
current version of ExceLINX allows you to specify sampling rate when the
function is set to continuity. This is not allowed by the instruments and the
setting is ignored. (PR14771)
Valid
trigger count values are 1-55,000 and infinity for the 2700, 1-110,000 and
infinity for the 2750, and 1-450,000 for the 2701. ExceLINX allows you to enter values above 55,000, and 110,000 respectively, but they are
treated as infinity. Therefore, if you
set the trigger count to a value greater than the above limits, the task will
run until you manually stop it. (PR15897, 15773, 16023, 16024, 16025)
The 2700
and 2750 allow you to specify a different value for the Displayed Digits setting
for each channel. ExceLINX only allows
one setting for all channels. (PR15792)
ExceLINX
attempts to maximize performance by only sending configuration values to the
instrument when they have been changed.
For example, when a configuration task is run for the first time, all
configuration values are sent to the instrument. If the task is run again without changing anything, most of the
values will not be written again. This
improves performance.
Caching of
configuration values can cause problems if the instrument is turned off, or
values are changed from the front panel instead of using ExceLINX. This can cause unexpected results. To avoid this problem, following a power
interruption to the instrument, or manual alteration of settings from the front
panel, you should close and re-open Excel, and then run the configuration or
scan task. This will force ExceLINX to
send all configuration data to the instrument.
The optional local lockout setting allows you to configure ExceLINX to
block access to the instruments front panel when ExceLINX is using the
instrument. (PR15937)
Invalid
alarm limit values are not flagged in red.
(PR19718)
Valid
range for the filter count setting is 1-100.
ExceLINX accepts values outside this range, but the instrument will
report an error. (PR15657)
If invalid
values are entered for the limit values, but the limits are disabled, the
invalid values will still be sent to the instrument resulting in an instrument
error. Do not enter invalid values for
the limit settings.
ExceLINX
allows entry of invalid values for limit settings, but they will result in an
instrument error when the task is executed. (PR16031, 16032)
ExceLINX
does not provide a way to specify the threshold setting for frequency
measurements. (PR19685)
ExceLINX
allows you to specify a different value for DB reference or RelDB reference for
each channel, but the instruments do not support this. Only one global
reference value is allowed. Specify the
same reference value on all channels using DB or RelDB. (PR16111)
ExceLINX
does not correctly handle trigger timer
values over 999,999. (PR16164)
ExceLINX
does not allow you to use math functions when the measurement function is set
to totalizer, although the instrument supports this. (PR16170)
The drop
down list for the monitor channel selection will include any disabled
channels. Do not select a disabled
channel or the ExceLINX task will run without collecting any data until
manually stopped. (PR16113)
Under
certain unusual circumstances, the scan task will not flag an invalid Starting
Row or Starting Column. Starting row
should be 36 or greater when data will be placed on the scan task worksheet.
(PR14739)
If the
reading count on the scan task is set to zero, it is not flagged as
invalid. If the task is then executed,
it will run until manually stopped, and will then display an error
message. The reading count must be
non-zero. (PR15583, 16219)
If a task
sheet is deleted, and then a new task is created, ExceLINX incorrectly warns of
a duplicate name. Clicking yes on the displayed dialog will force ExceLINX to
use the name. (PR15904)
When
performing 4 wire measurements, the instruments automatically pair two
channels. ExeLINX does not warn the
user if an attempt is made to separately configure the paired channel on the
same configuration spreadsheet. Exercise care when configuring 4 wire
measurements so the paired channel is not configured separately. (PR15925)
When
logging to a floppy disk, no warning is generated when the floppy becomes
full. It is recommended that logging be
to hard disk. The file can be
transferred to floppy when required. (PR15967)
ExceLINX
allows you to specify the scaling units character for each channel. The instruments will display this unit while
scanning, but the character is not stored in the instruments buffer with the
reading. Therefore, using the DMM Read
task to upload buffer contents will not display the proper units. (PR15987)
ExceLINX
allows you to specify limits settings when the function is set to continuity,
but the instrument does not allow this.
Do not enable limits when using continuity. (PR15994)
Under
Excel 97, quitting ExceLINX while a task is running will cause a run-time
error. After the error occurs,
ELXSDMMI.dll is left loaded and will prevent ExceLINX from functioning when it
is restarted. Restart your computer, or
use the Windows task manager to stop ELXSDMMI to recover. Stop any running
tasks before quitting Excel. (PR16106)
The
trigger delay and timer fields accept values up to 99,999,999.0 but the
instrument's maximum allowed value is 999,999.999. Do not exceed the instrument's maximum value. (PR16161, 16163)
Setting
the Rel filed on the configuration task to ACQ is intended to take a reading
from the specified channel and then use that as the relative reference for
subsequent measurements. In this
release, when ACQ is specified, the relative reference is set to zero
regardless of the input signal value.
Specifying
a relative reference manually by entering a value in the Rel field works
properly. (PR19846)
When using
manual trigger from within ExceLINX, if either the "Add Channels" or
"Add Units" options are set to yes in the Data Display Section of the
Scan task, the Trigger Icon on the toolbar will be disabled and a manual
trigger cannot be sent to the instrument.
When using manual trigger mode, set Add Channels and Add Units to
off. (PR19769)
