ProDAQ 6140 LXI Matrix Switching Unit User Manual

1. Introduction

1.1. Overview

The ProDAQ 6140 provides a relay matrix which can be fitted between the sensors and actuators on a device under test and the data acquisition and control system. It allows to separately connect/disconnect the signals from either side and concurrently to connect them to an internal bus. In this way signals can be routed via the bus to new destinations or the bus can be used to monitor or supply test signals. This allows calibrating and debugging the system without disconnecting and separating channels throughout the system wiring.

Figure 1 - ProDAQ 6140 LXI Matrix Switching Unit usage

All relays are latching DPST type relays which keep their set connection even during power off. For the DAQ/DUT signals high-density connectors with Low Force Helix contacts are used. Test signals can be accessed via standard 4mm banana-style sockets on the front panel. For scalability, the bus signals can be daisy-chained to additional ProDAQ 6140 units via D-Sub connectors on the rear panel.

The ProDAQ 3202 Voltage Reference plug-in can be installed in the unit and can be connected to either one of the four bus lines.

The ProDAQ 6140 LXI Matrix Switching Unit is a fully compliant LXI device supporting all LXI core functions via a Gigabit LAN interface.

1.2. Theory of Operation

The ProDAQ 6140 LXI Matrix Switching unit uses latching relays to maintain the set connections between the channels I/Os and bus lines even if it is not powered on. The relays itself do not allow the firmware and driver(s) to read back their actual state (open/closed). Instead the device starts to operate from a known state, the default setting (all relays open), and records all operations in an on-board EEPROM.

NOTE

To maintain relays states over power cycling (on/off), the ProDAQ 6140 does not reset the relays when powered on. To reset all relays, for example to use it in a new application, the driver functions must be used.

When writing application software, one must be aware of this fact as well. If the relay states shall be maintained, the application software must connect to the device without issuing a reset (see…).

1.3. Applications

Located between a data acquisition and control system and the device under test (DUT), the ProDAQ 6140 LXI Matrix Switching Unit can be used for a variety of applications. In its default mode, the unit simply connects all channels of the data acquisition and control system to the sensors and actuators located at the device under test:

1.4. Monitoring

Signals generated by a sensor on the DUT or by a signal source in the DAQC system can be monitored by switching the signal on one of the four bussed lines and connecting a scope or a DMM to its connectors on the front panel. This can be done in parallel to the actual use of the signal in the DUT and the DAQC system or the connection can be opened on one side to check the signal without the influence of the other side.

ProDAQ 6140 LXI Matrix Switching Unit User Manual

1.5. Calibration

A high-precision signal source (calibrator) connected to one of the bussed lines can be used to calibrate the channels of the data acquisition and control system without physically connecting or disconnecting any cables. Using a programmable unit with for example LXI interface allows doing a complete system calibration in a short time.

When the optional ProDAQ 3202 Voltage Reference is installed in the ProDAQ 6140, highly stable voltages between 4.5mV and 9V can be internally routed onto any of the four bus lines.

NOTE

The ProDAQ 3202 can only be installed in the factory. If your application wants to make use of it, you need to order it together with the ProDAQ 6140 initially or send the ProDAQ 6140 back for the installation.

1.6. Fault Insertion

The ProDAQ 6140 can be used to create a number of hardware fault conditions commonly used in hardware fault insertion testing for mission critical systems where such fault conditions must lead to

a known, deterministic response. Simply by opening one of the “X” or “Y” relays will simulate a

broken wire condition, whereas the bussed lines again can be used to short channels to ground, against each other or to a certain potential.

3.4. Mounting the ProDAQ 6140 in a 19” Rack

The ProDAQ 5725 Rack-mount Kit is available to mount the ProDAQ 6140 into standard 19” racks. The kit allows mounting the unit into racks with mounting depths between 453 mm and 843 mm. Please refer to the ProDAQ 5725 assembly instructions for usage.

3.5. Device Discovery

The most convenient way to start accessing a ProDAQ 6140 unit is to use one of the zeroconfiguration networking tools for your host computer that make use of the multicast DNS service supported by the ProDAQ 6140. With mDNS it is possible to access the device while not knowing the actual IP address.

3.5.1. Accessing the ProDAQ 6140 using Multicast DNS

Multicast DNS services are provided for Windows by the “Bonjour Print Services” (available at

support.apple.com) and for Linux by Avahi (available at www.avahi.org). The default mDNS service name for ProDAQ 6140 is:

Bustec Ltd – ProDAQ 6140 – <SERIAL NUMBER>

And the default host name is:

prodaq6140-<SERIAL NUMBER>.local

With the default host name, accessing the web interface is achieved with the following HTTP address:

http://prodaq6140-<SERIAL NUMBER>.local

When mDNS is used, the resource string for use with the VISA library can have the form:

TCPIP<n>::prodaq6140-<SERIAL NUMBER>.local::INSTR

The host name may be changed by the user, so having an automatic search for mDNS enabled

devices is very useful. The user doesn’t need to know neither the IP address nor the host name of

the device. If Bonjour (Windows) or Avahi (Linux) is running on the host, the Bustec Agent tool installed along with Bustec VISA package makes use of it. It scans for the available devices, lists them and allows opening their web interfaces. For more information on Bustec VISA please refer to Bustec VISA Library and Tools User Manual.

Figure 5 - Bustec VISA Agent Popup-menu showing LXI Devices

User Manual ProDAQ 6140 LXI Matrix Switching Unit

3.5.2. Discovering the ProDAQ 6140 using VXI-11 Broadcast

The Bustec VISA Configuration Utility can be used to discover ProDAQ 6140 units by using the VXI-11 protocol. After starting the configuration utility, select the “Network Instruments” tab and click on the button “Find Instruments”. To discover a ProDAQ 6140, the device type “INST” with device number 0 must be included in the

search criteria shown in the “Find Network Instruments” dialog before you click the button “Search for Instruments”. (By default these criteria are included)

When the search finishes, discovered instruments are shown in the list below. Use the buttons “Add All” or “Add Selected” to add the instruments to the list of known network instruments. This is necessary to allow the VISA library and soft front panels to access the devices. For the detailed description of the procedure please refer to the Bustec VISA Library and Tools User Manual.

Figure 6 - ProDAQ 6140 discovered using the VISA Configuration Utility

The VXI-11 discovery returns the IP address of the devices found, so that the resource string shown her have the form

TCPIP<n>::<IP Address>::INSTR

Now you can use the embedded web interface or the VISA driver to access, configure and operate the ProDAQ 6140 LXI Matrix Switching unit.

Gateway and DNS servers.

TCP/IP mode

Specifies whether the device shall use a DHCP server in the network, or AutoIP protocol to automatically obtain the IP configuration, or maybe the static IP configuration defined in the form below.

More than one option may be selected. The priority is as follows:

DHCP → AutoIP → Static. For example, if DHCP and Static are

selected and DHCP fails, the Static configuration is set.

IP Address

If "Static IP" was selected as the TCP/IP mode, this field allows assignment of a static IP address to the ProDAQ 6140s LAN interface.

Subnet mask

If "Static IP" was selected as the TCP/IP mode, this field allows assignment of a static subnet mask address to the ProDAQ 6140s LAN interface.

Default Gateway

If "Static IP" was selected as the TCP/IP mode, this field allows assignment of a static default gateway for the routing of IP packets.

DNS Servers

If "Static IP" was selected as the TCP/IP mode, these two fields allow you to specify the DNS server the ProDAQ 6100 will use for name

resolving. If “DHCP” was selected as the TCP/IP mode, then it is possible to select whether the DNS servers’ IP addresses shall be

acquired automatically (DHCP) or user-defined (Static).

MTU

Maximum Transmission Unit (MTU) – maximum size (in bytes) of an IP packet that can be transmitted without fragmentation (including IP headers, but excluding headers from lower levels in the protocol stack).

The default value for a typical network is 1500 B. It can be defined as high as 9000 B (jumbo frames). For correct interoperation, the whole network must have the same MTU.

4.3. Relay Configuration

The Relay Configuration page provides user-friendly control over the whole relay matrix. The graphical tool is divided into three parts (from top to bottom):

- A command area with three tabs allowing to select preset commands, relay group switch commands and alias settings commands.

- The interactive schematic area which shows the current status of the physical connections inside of the matrix and allows changing relay states, setting channel names (aliases) and selecting voltage for the built-in voltage reference device (if fitted).

- The bottom bar with display options, image export capability and general apply and undo buttons.

Figure 9 - Relay Configuration Page

By default, only the first 48 channels are displayed. It is because some web browsers may not handle very big image canvases that would be required to display the whole relay matrix. Use the combo box in the bottom left corner to select the range and scaling.

ProDAQ 6140 LXI Matrix Switching Unit User Manual

4.3.1. Relay Operation

To change the state of the relays, you can operate single relays by just clicking a relay in the displayed schematic or you can operate groups of relays by using the commands available in the “Open/Close Relays” tab of the command area.

Changes to the relay states are not immediately applied on the device. Those being in a different state than currently set on the device are marked with a yellow frame. To apply the changes, the “Apply” button in the lower right corner of the window must be pressed. Only the relays which states have been changed are affected. Before the changes are applied, they can be reverted by pressing “Undo” and “Undo all” buttons.

Figure 11 shows an example where the states of the relays X3, X4, Y3 and Y4 were toggled, but

the apply button wasn’t used to update the relays on the device. Relays X3 and Y3 were changed from the “open” state to “closed” while relays X4 and Y4 were changed from “open” to “closed”.

Figure 12 shows the same schematic after the apply button was pressed.

Figure 12 - Applying the changes

Toggling the relays independently may sometimes be time consuming. In such a case the group switching options available in the “Open/Close Relays” tab are useful.

Figure 13 - Open/Close Relays Tab

You can either choose a standard command from the drop-down list on the left and use the “Set”

button next to it, or type in a list expression in the text field on the right and use the “Open” or

“Close” buttons to open/close the relays contained in the list expression.

Note

Please note that these commands operate ONLY on the displayed schematic in the same way a direct operation by clicking on a relay in the schematic operates. To apply the changes to the device, the “Apply” button below the schematic must still be used.

ProDAQ 6140 LXI Matrix Switching Unit User Manual

The standard commands in the drop-down list allow opening all relays, opening all relays in one of the columns (X, A, B, C, D, “Y”) or closing all relays in either the X or Y columns.

The list expression must be a comma separated list of single relays or relay ranges. Single relays

are expressed by using the letters “A”, “B”, “C”, “D”, “X” or “Y” for the column (signal connections

“X” and “Y” and bussed channel connections “A”, “B”, “C” or “D”) and a number channel number;

e.g. “X1”, “B23” or “Y99”. Relay ranges are expressed by using the same letters to select the

column and a starting and ending channel number separated by a dash “-“ (minus); e.g. “X2-6” or “A1-180”.

Figure 14shows an example of a list expression using both single relays and relay ranges:

“X2-6,Y2-6,A1,B2,C3”.

This list expression selects the “X” and “Y” relays for channel 2 to 6 as well as the “A” relay for

channel 1, the “B” relay for channel 2 and the “C” relay for channel 3.

Figure 14 - Using a list expression

The list expression is immediately checked while typing and the relays effected are marked with a red frame in the schematic. In this way the correctness of the list expression can be checked

before pressing the “Open” or “Close” button to operate the selected relays in the schematic. If a

relay contained in a list expression is already in the correct state it is not affected by the command.

Once you press “Open” or “Close”, the affected relays are operated in the schematic and marked

with a yellow frame to be changed on the device when you press the “Apply” button below the

schematic.

4.3.2. Aliases

Individual channel names (aliases) can be assigned to all channels in the schematic for a better overview during operation. The channel names are displayed next to the related connector. To

User Manual ProDAQ 6140 LXI Matrix Switching Unit

assign or edit a channel name, just hover the mouse next to connector until the text field shows its selected state in a different color shade (see Figure 15) and click on it.

Figure 15 - Selecting a Channel Name (Alias) Field for Editing

Once clicked, a popup dialog with a text edit field allows you to enter or edit the alias. Press “Save”

to save the changes or “Cancel” to leave the dialog without applying the change. Once an alias is edited, the change is immediately stored on the ProDAQ 6140 device. Each alias

can be up to 31 characters long.

Figure 16 - Editing the Channel Name (Alias) for Channel X2

To clear an alias, delete the name in the edit popup or use the commands in the drop-down list of the “Aliases” tab in the command area to clear all or parts of the aliases.

Figure 17 - Aliases Tab

4.3.3. Presets

The entire device configuration of the ProDAQ 6140 can be stored on the device as a preset under a name and reapplied by loading it. A device configuration (preset) consists of the relay settings, assigned aliases as well as a voltage reference setting (if installed). Command to manage presets can be found in the “Presets” tab in the command area.

Figure 18 - Presets Tab

ProDAQ 6140 LXI Matrix Switching Unit User Manual

To save a preset, type the name in the “New:” text field and press the “Save” button. The name can be up to 31 characters long and can contain only alpha numeric characters, underscores and hyphens. When a preset with the same name already exists, a warning message is displayed asking for confirmation whether to overwrite it or not. If there are any unapplied changes made to the relays (changes made to the schematic without applying them to the device) a dialog shows up offering to update the device first.

To load and apply a previously stored preset select it in the “Existing” drop-down list and press “Load”. This operation updates both the device and the schematic editor.

WARNING

When a preset is loaded, it is automatically applied on the ProDAQ 6140 device. All the relays are set accordingly to the preset’s configuration.

If a preset was loaded, its name is displayed in the lower right corner next to the “Apply” button (see Figure 19). If further changes to the device configuration are made by operating relays, changing channel names etc and applying the changes to the device, a warning is shown that the current configuration does not correspond any longer to the preset (“preset not saved”, see Figure

20)

Figure 19 - Preset Name Display

Figure 20 - “preset not saved” Warning

Presets can also be stored onto or loaded from the host computer running the web browser. To do

so, press the “Management…” button in the “Presets” tab in the command area. A popup dialog

appears where you can either select an existing preset in the drop-down list and use the “Save to

File” button to store it on the host computer or use the “Browse…” button to select a previously

stored preset and upload it to the device by pressing “Load from File”.

5. Software Driver

To include operation of the ProDAQ 6140 LXI Matrix Switching Unit into your application, you need to install one of the available software drivers on your computer. In addition to the driver according to the IVI standard (IVI-C) as required by the LXI standard Bustec provides for users familiar with the VXIplug&play standard a VXIplug&play driver. Both drivers require that a VISA library is installed on the computer.

5.1. Installation

In order to install the software, run the ProDAQ 6140 installer package, 32 or 64 bit – appropriate to the operating system, and accept the license agreement. The files are copied by default to the IVIStandardRootDir respectively the VXIPNPPATH location.

Figure 31 - Example Installation Dialog

5.2. Soft Front Panel

The driver according to the VXIplug&play standard comes with a soft front panel application that allows you to operate the device. It is a standalone application that has similar capabilities as the ProDAQ 6140 WEB Interface. There are however some differences on the user experience level that come from the differences between technologies used – HTTP with JavaScript vs. standalone GUI application.

One of the advantages of using the Soft Front Panel application over the WEB interface is that it allows working off-line. Working off-line it is possible to create and modify presets (saved states of the device configuration) without a physical connection to a ProDAQ 6140.

5.2.1. Starting the Soft Front Panel

To start the soft front panel application, select it in the start menu (“Start”  “Programs”  “VXIPNP”  “ProDAQ 6140”  “Soft Front Panel”). After the start of the soft front panel

application, the user has the choice to either enter the address information (VISA resource specification) of the ProDAQ 6140 the soft front panel application shall connect to, use the build-in auto find functionality to discover accessible ProDAQ 6140 units cards or run in demo mode.

User Manual ProDAQ 6140 LXI Matrix Switching Unit

Figure 32 - Selecting the Connection Method

Please note that when using the Bustec VISA library, the auto find functionality will only inspect network resources that are known to the VISA library to avoid unwanted accesses of network resources that might be unintentionally reachable via the local network. Use the Bustec VISA Configuration Tool to find and manage network instruments (refer to the Bustec VISA library and Tools Manual for details).

If “Auto Find” is selected, the user will be presented with a dialog box showing all available ProDAQ 6140 units, allowing the selection of the one unit to connect to. If there is only one unit available, the dialog box will not appear and the soft front panel application will automatically establish the communication to this instrument.

If “Enter Address” is selected, a dialog is shown that allows you to directly enter VISA resource string using the IP address or host name of the instrument.

Figure 33 - Specifying the Instrument Address

If no ProDAQ 6140 is available in your system or to create/edit presets, the soft front panel application can be run in demo (offline) mode.

ProDAQ 6140 LXI Matrix Switching Unit User Manual

Offline Operation (Demo Mode)

The biggest advantage of using the Soft Front Panel application over the WEB interface is that it allows working off-line in demo mode. When in demo mode, the device operation is completely simulated. It is allowed to switch the relays, set aliases, save, load, export and import presets, etc. All the settings are stored in Windows Registry and therefore are not lost when program is restarted.

The main purpose for working off-line is that it is possible to create and modify presets without physical connection to ProDAQ 6140. A preset can be imported from and exported to a file. The file for import can be taken from the real device for modification and the exported file can be uploaded to ProDAQ 6140. Please note that there are two types of preset files that are not compatible with each other – for the AA and AB models. Therefore if you select “Demo Mode” from the dialog shown in Figure 32, an additional dialog allows you to choose the model which shall be used in offline mode.

Figure 34 - Demo Mode Model Selection

Online Operation

When the Soft Front Panel works in online mode, the “Active” LED indicator that can be found in

the upper right corner of the main window is green.

WARNING

Working in online mode means that all the applied changes are immediately applied to the connected ProDAQ 6140.

5.2.2. Operating the Soft Front Panel

The Soft Front Panel application allows user-friendly control over the whole relay matrix. Its main window is divided into three parts:

- The interactive schematic area which shows the physical connections inside of the matrix. It also allows changing the relay states, setting channel names (aliases), selecting voltage for the built-in Voltage Reference device (if fitted) and letting some additional operations on groups of relays at once.

- The bottom bar with display options, image export capability and what is most important – Apply and Undo buttons.

- Additional options grouped in a panel on the right side of the window.

User Manual ProDAQ 6140 LXI Matrix Switching Unit

Figure 35 -Soft Front Panel Application User Interface

Relay Operation

In order to switch the state of a relay just click on it on the schematic. Closed relays are marked with green color for clarity.

Figure 36 - Switching a Relay to its “Closed” State

The relays are not immediately switched on the ProDAQ 6140. Those being in a different state than is currently set on the device are additionally marked with a yellow frame. The last changes

that haven’t been written to the device yet can be reverted by pressing “Undo” and “Undo all”

buttons. The same applies to the built-in Voltage Reference’s setting.

To apply the changes and write them to the device, the “Apply” button in the lower right corner of

the main window must be pressed. Only the relays which states have been changed are affected.

Figure 38 - After Apply Button was pressed

User Manual ProDAQ 6140 LXI Matrix Switching Unit

Toggling the relays independently may sometimes be time consuming. In such a case the group switching options available in the context menus for each of the relays are useful. They allow opening all relays, or opening the whole column: X, Y, A, B, C , or D. Also closing the whole X or Y

column is possible. When the “Custom Pattern…” option is selected, the user can enter a list

expression describing the group of relays to be switched.

Figure 39 - Relay Context Menus

The list expression must be a comma separated list of single relays or relay ranges. Single relays

are expressed by using the letters “A”, “B”, “C”, “D”, “X” or “Y” for the column (signal connections “X” and “Y” and bussed channel connections “A”, “B”, “C” or “D”) and a number channel number; e.g. “X1”, “B23” or “Y99”. Relay ranges are expressed by using the same letters to select the

column and a starting and ending channel number separated by a dash “-“ (minus); e.g. “X2-6” or “A1-180”.

Figure 40 shows an example of a list expression using both single relays and relay ranges. The list

expression selects the “X” and “Y” relays for channel 2 to 6 as well as the “A” relay for channel 1,

the “B” relay for channel 2 and the “C” relay for channel 3.

To clear an alias, delete the name in the edit field or use the popup context menu which is available by doing a right-click on the alias.

Figure 43 - Alias Context Menu Example

Presets

The presets are device configuration states saved to files and stored on the ProDAQ 6140 device. It is possible to save any state that is currently set on the device including not only all the relay states, but also the aliases and voltage reference setting.

User Manual ProDAQ 6140 LXI Matrix Switching Unit

In order to save a preset please apply the relay state changes that were made on the page, but

haven’t been written to the device yet. Then press “Save Preset…” button to open the confirmation

dialog window and type the new preset name, or select an existing preset to be overwritten. If there were unapplied changes made to the relays, a warning dialog appears asking whether to apply and continue, or cancel.

Figure 44 - Save Preset Dialog

The name of a preset can be up to 63 characters long and can contain only alpha numeric characters, underscores and hyphens. When a preset with the same name already exists a warning message is displayed asking for confirmation whether to overwrite it or not.

To load a previously stored preset just press the “Load Preset…” button in the main window and choose one from the drop down list.

Figure 45 - Load Preset Dialog

Note

Creating a preset requires either setting the desired configuration on the ProDAQ 6140 device or to run the Soft Front Panel offline in demo mode.

WARNING

When a preset is loaded, it is automatically applied on the ProDAQ 6140 device. All the relays are set accordingly to the preset’s configuration.

If a preset was loaded or saved, its name is displayed in the lower right corner next to the “Apply” button (see Figure 46). If further changes to the device configuration are made by operating relays, changing channel names etc and applying the changes to the device, a warning is shown that the current configuration does not correspond any longer to the preset (“preset not saved”, see Figure

47)

5.3. Using the VXIplug&play Driver

This chapter shows how to operate the ProDAQ 6140 LXI Matrix Switching Unit using the VXIplug&play driver. The code section(s) shown are used to explain the basic functionality only, complete examples can be found in the “Examples” subdirectory of the driver. All functions are explained in detail in the help file coming with the driver.

5.3.1. Connecting to the device

To initialize the driver and connect to the ProDAQ 6140, the standard VXIplug&play initialization function bu6140_init() is used. The resource string can use the form shown in section 3.5.1 if mDNS is used (see Figure 49, ) or the IP address of the device (see Figure 49, ).

Please refer to the VXIplug&play standard VPP-4.3, section 4.3 for a detailed description of the address string used.

Figure 49 - Connecting to the ProDAQ 6140

WARNING

To maintain the relay states when starting and stopping your application, you need to set the <resetDevice> parameter of the bu6140_init() function to VI_FALSE as shown above. Specifying VI_TRUE will reset all relays to their default state (“open”) when you connect to the device.

To close a session with the ProDAQ 6140 LXI Matrix Switching Unit, the standard VXIplug&play function bu6140_close() must be used.

#include <visa.h> #include <bu6140.h>

main (int argc, char **argv) { ViStatus status; ViSession session; ViChar descr[256];

/* connect to the ProDAQ 6140 using mDNS host name */ if ((status = bu6140_init(“TCPIP0::prodaq6140-<SERIAL NO>.local::INSTR”, VI_TRUE, VI_FALSE, &session)) < VI_SUCCESS) { bu6140_error_message(session, status, errMsg); printf (“Error: bu6140_init() failed due to %s\n”, descr);

5.3.2. Operating Relays

To operate a single relay, the driver function bu6140_setRelayState() can be used (see Figure 50, ). As parameters you need to specify the relay column (channel I/Os “X”, “Y” or bus lines “A”,

“B”, “C” and “D”), the row (1-96 for ProDAQ 6140 versions “AA” and “BA” or 1-192 for ProDAQ 6140 versions “AB” and “BB”) and the state the relay shall be switched to. The relay column as well

as the relay state can be specified using a predefined macro from the bu6140.h include file or the corresponding numerical value (see driver help file). Predefined macros for the matrix columns are

bu6140_CHANNEL_X for the relay connecting the channel I/O “X” bu6140_CHANNEL_Y for the relay connecting the channel I/O “Y” bu6140_LINE_A for the relay connecting line “A” to the row bu6140_LINE_B for the relay connecting line “B” to the row bu6140_LINE_C for the relay connecting line “C” to the row bu6140_LINE_D for the relay connecting line “D” to the row

Figure 50 - Operating a Relay

The function bu6140_getRelayState() can be used to inquire the current status of a relay in the same way (see Figure 50, ).

To switch multiple relays with one command, the function bu6140_changeMatrixState() can be used (see Figure 51, ). It receives as parameter two arrays with 32-bit values. The first array

contains a bit mask where, if a bit is set to one (1), the corresponding relay is switched to its “open”

state, while the second array contains a bit mask where, if a bit is set to one (1), the corresponding

relay is switched to its “closed” state. Bits that are zero “0” will leave the state of the corresponding relay unchanged. For the ProDAQ 6140 versions “AA” and “BA” the array must contain 18 values;

for the versions “AB” and “BB” it must contain 36 values. The bits in the bit masks correspond to

the relays in the way as shown in Table 1 and Table 2 ( also Figure 51,  and ). When executing

Figure 51 - Switching multiple Relays

To set all relays to a certain state, use the driver function bu6140_setMatrixState() (see Figure 52, ). It expects as the second parameter an array of 32-bit values where each bit of the values

represent the state of a relay in the matrix. For ProDAQ 6140 versions “AA” and “BA” the array must contain 18 values; for the versions “AB” and “BB” it must contain 36 values. A bit equal to one

5.3.4. Storing and retrieving Aliases

Aliases (channel names) can be stored to the device and retrieved by using the functions

bu6140_setAlias() and bu6140_getAlias(). Both function require two integers defining the

column and row as well as a character array for the alias as parameters. The column parameter defines the channel I/O or line in the same way as the bu6140_[s|g]etRelayState() functions.

The row parameter is only valid for the channel I/Os “X” and “Y”, as the lines “A”, “B”, “C” and “D”

have only one alias. If you select one of them as column, the row parameter is ignored. To allow access to all aliases with one function call, you can also specify VI_NULL (0) as the

column. In that case the function bu6140_setAlias()will clear all stored aliases, while the function

bu6140_getAlias() will retrieve all aliases in a comma-separated list.

The alias parameter is a character array that contains the alias to be set or receives the alias(es) to be retrieved. It is the responsibility of the user to ensure the correct length of the array. A single alias can be 31 characters long, so that the array needs to have at least 32 elements. To retrieve all aliases, it must have (192 * 32) + (192 * 32) + (4 * 32) = 12416 elements.

#include <visa.h> #include <bu6140.h>

main (int argc, char **argv) { ViStatus status; ViSession session; ViChar descr[256];

/* ... */

/* set the output of the voltage reference to 4.5 Volt */ if ((status = bu6140_setVoltRefOutput (session, 4.5)) < VI_SUCCESS) { bu6140_error_message (session, status, errMsg); printf (“Error: bu6140_setVoltRefOutput() failed due to %s\n”, descr); bu6140_close (session); return -1; }

/* connect the voltage reference to line “C” */ if ((status = bu6140_setVoltRefConnectionState (session, bu6140_LINE_C, bu6140_CONNECT)) < VI_SUCCESS) { bu6140_error_message (session, status, errMsg); printf (“Error: bu6140_setVoltRefConnectionState() failed due to %s\n”, descr); bu6140_close (session); return -1; }

/* switch the relay connecting line “C” to row 6 to “closed” */ if ((status = bu6140_setRelayState (session, bu6140_LINE_C, 6, bu6140_CLOSED)) < VI_SUCCESS) { bu6140_error_message (session, status, errMsg); printf (“Error: bu6140_setRelayState() failed due to %s\n”, descr); bu6140_close (session); return -1; }

5.3.5. Managing Presets

The actual state of the ProDAQ 6140 unit - consisting of the relay states, list of aliases, voltage reference output setting (if installed) and voltage reference connection setting (if installed) - can be named and stored on the device. Once stored, it can be recalled by the assigned name, allowing to set the whole unit to a defined state with a single operation.

The presets saved on the device can also be store into a file or loaded from one. Please note that the preset files for the 96 and 192 channel versions of the ProDAQ 6140 are not compatible and need to be handled separately.

To further improve the management of the presets, they can be deleted from the device using the assigned name and a list of names of the existing configurations can be retrieved.

To store a configuration, first switch all relays to the desired state, assign aliases as needs and handle the voltage reference. Then use the function bu6140_storePreset() with a meaningful name to store the current state of the device. The name passed can be 63 characters long.

If you want to restore this preset, call the function bu6140_restorePreset() with the name assigned when calling bu6140_storePreset(). Now all relays are switched to the states stored, all aliases set and the voltage reference connection and output value set.

For more details, refer to the driver documentation and help file.
