Chapter 1 System Configuration

1.1 About the PC-Based Measurement Instruments WE7000

The WE7000 is a new type of PC-based measurement instruments integrating YOKOGAWA’s analog, digital, and software technologies. The measuring station capable of holding various measurement modules can be connected to the computer with both the station and the computer can be connected to the Ethernet (10 BASE-T/ 100BASE-TX) or USB allowing for the construction of a high-speed, multi-channel, diversified measurement system. In addition, the optical interface module and optical interface card that are sold separately can be used to make connections using optical fiber cables (see Appendix 1, “Optical Interface”).

Various measurement module sets are available including a digital oscilloscope, a function generator, a counter, and a digitizer which allows measurements from DC to high frequency regions.

Because the insertion and removal of measurement modules and the addition of measuring stations are recognized automatically by plug & play, the system can be easily modified.

Until now, PC-based measurement systems invoked complaints such as: “Writing programs takes too much time,” “Transferring of the measured data takes too long for practical use,” “Not enough space to combine multiple instruments,” and “Wiring is too complicated.”

System Configuration

The WE7000 solves these problems and provides a measurement environment which incorporates multimedia.

1.2 WE7000 System Configuration

WE7000 Hardware Configuration

The WE7000 is comprised of the following hardware.

Measuring station

The measuring station consists of a case for installing modules, a CPU, a trigger control circuit, a power supply circuit, ethernet interface, USB interface, and a proprietary WE bus. The CPU identifies modules, controls the communication between the module and the PC, and performs data compression. The WE bus is used for transferring synchronous signals generated by a trigger from another module in the same station and also for transferring measured data. You can define two systems of triggers and one system of time base. See section 1.5, “About the Trigger Source/Time Base Source/ Arming Settings” for details.

The setup data you set on the PC is transferred from the ethernet interface or USB interface to the measuring station. Signals that enter each measurement module are processed according to the setup data and are output to the WE bus. The output signal from the measurement module is in the form specified by the information in the setup data. Then, the measured data on the WE bus is transferred to the PC through the ethernet interface or USB interface.

In place of the Ethernet or USB port, an optical interface module can be installed for communication with a PC, similar to Ethernet or USB communication, via an optical fiber cable. For a description of optical communication, see Appendix 1, “Optical Interface.”

The external input/output connector (EXT. I/O) is used for inputting/outputting trigger and simple DIO, and clock signals as well as outputting the active state signal of the WE bus. The external trigger input connector (TRIG) is used to input external trigger signal.

1.4 About the Software for the WE7000

The following software applications are provided for use on the WE7000.

WE7000 Control Software

By installing the accessory WE7000 Control Software on the PC, you will be able to control the WE7000 and process the measured data as follows.

•Turning the Measuring Station ON/OFF

If the measuring station is in the standby condition, you can turn ON/OFF the power on the measuring station from the PC. However, you cannot do this through the serial interface.

• Monitoring the Measuring Station’s or Measurement Module’s Conditions

If the measuring station is in the standby condition, you can check, in realtime, whether or not each measuring station is connected or whether each station is turned ON/OFF. You can also check whether or not a module is installed on each of the measuring stations.

• Displaying the Operation Panel of Measurement Modules and Controlling Measurement Operations

The operation panel of each measurement module is displayed by a click of an icon, and measurement conditions can be set easily using the operation panel. Output conditions from modules that output signals are also set in a similar manner.

System Configuration

Synchronized operation is also possible on modules of the same type. For example, multiple digital oscilloscopes can be linked together and be used to measure multiple channels.

• Displaying Measured Data

For modules such as the digital oscilloscope that needs to display the measured waveform, a waveform monitor is displayed. Using the waveform monitor, the many possible activities include: measuring the waveform with the cursor, zooming on the data, saving measured data, and copying the data to the clipboard.

1.5 About the Trigger Source/Time Base Source/ Arming Setting

Bus Trigger Signal and Time Base Signal

Measuring Station WE400/WE800 is equipped with a bus for inputting/outputting two trigger signals (bus trigger signals, BUSTRG1 and BUSTRG2) and one time base signal (CMNCLK) to the I/O terminals on each of the modules and the front panel.

The bus trigger signal is used to provide the timing in acquiring the data. For example, on the 100 MS/s Digital Oscilloscope WE7111, data are acquired before and after the point at which the bus trigger signal becomes “True.” Each measurement module defines its own timing of receiving the bus trigger signal and the operation that is performed when the bus trigger signal becomes “True.” For details on the operation, refer to the User’s Manual for the measurement module.

The time base signal is used to provide the timing for the A/D and D/A sampling and the time for latching the digital signal. The measurement modules that are provided with the time base signal sample the data when the time base signal changes from “False” to “True.”

The bus trigger signal and the time base signal are provided by the following six sources.

1. Measurement module (modules equipped with bus trigger/time base output function).

2. Input signal from the external trigger input terminal (TRIG IN) on the front panel of the measuring station.

3. Input signal from the external input/output connector (EXT. I/O) on the front panel of the measuring station.

4. Communication module that is installed at slot 0 of the measuring station.

5. Clicking the “Generate manual bus trigger” button on the trigger source/time base source setting dialog box (bus trigger only).

6. Selecting “Generate bus trigger signal” in the menu that appears by clicking the right mouse button on the station list window of the WE7000 Control Software (bus trigger only).

System Configuration

You can specify multiple sources for the bus trigger signal. The AND/OR is taken on the multiple source signals to determine the bus trigger signal state. The selection of whether to use the AND or OR, and the selection of the sources for the bus trigger signal are set using the trigger source/time base source setting dialog box (see section 4.6, “Setting the Trigger Source/Time Base Source/Arming”).

When taking the AND on the bus

Note

• When taking the AND/OR on multiple trigger signals that change about the same time, a glitch may result on the bus trigger signal. To avoid this, adjust the timing of each of the trigger signals.

• Note that the trigger signal that is generated by clicking the generate manual trigger button in the trigger source/time base source setting dialog box is one of the bus trigger signal sources. Therefore, if you selected AND computation, you must turn this button ON and generate the trigger signal on the bus in order for the bus trigger to become “True.”

One source from source 1 to 4 given above can be output as the time base signal. If there are several modules that can provide the time base signal, only one is used. The time base signal source is also set in the trigger source/time base source setting dialog box (see section 4.6, “Setting the Trigger Source/Time Base Source/Arming”).

1.5 About the Trigger Source/Time Base Source/Arming Setting

Trigger/Time Base Signal Input/Output of the Measurement Module

When using a measurement module equipped with a trigger/time base input/output function, the bus trigger signal and time base signal can be input/output from the measurement module by using the trigger source/time base source setting dialog box. A bus trigger signal can be passed to another measurement module with the detection of an internal trigger. The bus trigger signal, then can be used to trigger the other measurement module. You can also output the internal time base signal of a measurement module to the bus, or operate a measurement module according to the time base signal.

Please note that a module will not start detecting the bus trigger just by setting the module to input the bus trigger signal in the trigger source/time base source setting dialog box. Make sure to select [BUSTRG] for the [Source] setting in the operation panel of the measurement module (see section 4.6, “Setting the Trigger Source/Time Base Source/Arming”).

Similarly, a measurement module will not start using the time base signal just by setting the module to input the time base signal in the trigger source/time base source setting dialog box. Make sure to select [BUSCLK] for the [Time Base] setting (the name maybe different on different modules) on the operation panel (see section 4.6, “Setting the Trigger Source/Time Base Source/Arming”).

If you set the bus trigger signal/time base signal to be output to the bus in the trigger source/time base source setting dialog box, the trigger/time base signal generated in the module is output to the bus. For the timings of the trigger/time base signal, see the manual of the measurement module.

Bus trigger signal

You can use the trigger/time base signal input/output function to synchronize the trigger timings among measurement modules of different type, and perform synchronized sampling operation. For example, you can have the 32-Bit Pattern I/O Module WE7131 output a bus trigger signal upon detecting a pattern match in the digital input, and the 100 MS/s Digital Oscilloscope Module WE7111 can use the trigger signal to measure the signal around the pattern matching point. As another example, you can use the 10 MHz Function Generator Module WE7121 to generate a 10.24-kHz time base signal, and the 10-CH, 100 kS/s Digitizer Module WE7251 can synchronize to that signal to perform A/D conversion.

Some measurement modules can output a bus trigger signal upon detecting a trigger within the module, and receive the results of the AND/OR computation on the bus to trigger the actual trigger operation. When using the module in this way, set the connection between the module and the bus trigger source to “input and output” in the trigger source/time base source setting dialog box.

1.5 About the Trigger Source/Time Base Source/Arming Setting

Note

When the frequency of the internal time base signal of a measurement module is above 10 MHz, the system may not operate properly if this signal is output to the bus. Make sure the frequency of the time base signal that is output to the bus is below 10 MHz.

Input from the Trigger Input/Output Terminal (TRIG)

Input

You can use the external trigger input terminal (TRIG) to input external bus trigger signals and time base signals. For example, a measurement module can be triggered by synchronizing to a trigger signal from an external device.

The input signal is a CMOS level signal and the polarity can be selected. The delay time between the external trigger input (TRIG) and the internal station trigger signal is as follows: External trigger input (TRIG) → bus trigger signal: 40 ns (typical value*) External trigger input (TRIG) → time base signal: 35 ns (typical value*)

*Typical values represents typical or average values. They are not strictly

guaranteed.

The pulse width of the external bus trigger signal must at least be 100 ns (or 50 µs when using it as an arming source). The pulse width of the external time base signal must at least be 100 ns, and the frequency must be 5 MHz or below.

System Configuration

Output

Either the bus trigger signal or time base signal of the measuring station can be output using the trigger input/output terminal (TRIG). The input signal is CMOS level, and the polarity is selectable. Note that when outputting the bus trigger signal, the pulse width of the output waveform varies depending on the bus trigger computation setting. If an AND operation is performed on the bus, the bus trigger signal may be an extremely short pulse (see page 1-9). Likewise, if the time during which the trigger is false is short in an OR operation, the false bus trigger signal may not be output accurately.

1.5 About the Trigger Source/Time Base Source/Arming Setting

Input/Output from the External Input/Output Connector (EXT. I/O)

By using the external input/output connector (EXT. I/O), you can input bus trigger signals and time base signals from outside the measuring station and visa versa. You can select whether to input or output a signal from the external input/output connector (EXT. I/O) in the trigger source/time base source setting dialog box.

When inputting/outputting a bus trigger signal from the external input/output connector (EXT. I/O), the polarity of the signal varies depending on whether the measuring station is taking the AND or OR of the bus trigger signals. When taking the AND, the trigger within the measuring station becomes “True” when the external signal is low. Conversely, when taking the OR, the trigger within the measuring station becomes “True” when the external signal is high. When inputting/outputting a time base signal, the time base signal within the station becomes “True” when the external signal is high. Therefore, sampling will occur on the rising edge of the external signal.

The delay time when inputting a bus trigger signal from the external input/output connector (EXT.I/O) is approximately 25 ns (typical value*). The delay time when inputting a time base signal is approximately 10 ns (typical value*). In addition, the delay time when outputting a bus trigger signal or a time base signal to the external input/ output connector (EXT. I/O) is approximately 25 ns (typical value*).

*Typical values represents typical or average values. They are not strictly

guaranteed.

As in the trigger input/output terminal, the pulse width of the external bus trigger signal must be at least 100 ns (or 50 ms when using it as an arming source). The pulse width of the external time base signal must at least be 100 ns, and the frequency must be 5 MHz or less.

By outputting the bus trigger signal/time base signal from the external input/output connector (EXT. I/O) of one measuring station and inputting it to another station, you can synchronize multiple measuring stations.

In such connections, there is an output impedance of approximately 100 Ω at the external input/output connector (EXT. I/O). Thus, using a long connection cable can deteriorate the waveform due to noise and capacity of the cable. This, in turn, can cause long delays and improper operation. Therefore, make sure to use a shielded cable and keep the length of the cable under two meters.

Arming Signal

1.5 About the Trigger Source/Time Base Source/Arming Setting

An arming signal is provided so that multiple measurement modules that are installed in the measuring station can start their measurements simultaneously. To use the arming signal, connect the arming signal (ARM) bus and the measurement modules in the trigger source/time base source setting dialog box.

The measurement modules that are connected to the arming signal bus enter the arming signal wait state when the [Start] button on the module's operation panel is clicked. Measurements start when the arming signal becomes [True]. If [Repeat] of the [Start] button is checked, the module enters the arming signal wait state after each measurement. For example, if the 100 MS/s digital oscilloscope module WE7111 is connected to the arming signal bus and the [Repeat] box is checked, the module enters the arming signal wait state every time it acquires the waveform once.

In order to start multiple modules simultaneously, connect each module to the arming signal, click the [Start] button on the operation panel to enter the arming signal wait state, and set the arming signal to [True]. The difference in the start times between modules is 10 ms or less.

The arming signal is provided by the following three sources.

1. Bus trigger signal (BUSTRG1 or BUSTRG2)

2. Clicking the “Manual Arming” button on the trigger source/time base source setting dialog box (bus trigger only).

3. Selecting [Generate Arming Signal] in the menu that appears by clicking the right mouse button on the stationlist window of the WE7000 Control Software (bus trigger only).

System Configuration

Use the trigger source/time base source setting dialog box to set the bus trigger signal for the arming signal’s source.

You can generate an arming signal across multiple measuring stations almost simultaneously (10 ms or less between stations) by selecting the station icons in the station list window of the WE7000 Control Software and then generating the arming signal by selecting [Generate Arming Signal] in the menu that appears by clicking the right mouse button.

By assigning the bus trigger signal to be the arming signal’s source, you can start multiple modules simultaneously using an external trigger signal thereby collecting data synchronously.

For example, you can take the following steps to start the measurement modules simultaneously.

1. Input a bus trigger signal (BUSTRG1) through the TRIG input

2. Set the arming signal’s source to bus trigger signal (BUSTRG1)

3. Connect the modules that you wish to start simultaneously to the arming signal bus.

Click the [Start] button on each module to enter the arming signal wait state and apply the trigger signal from the TRIG input. The measurement modules simultaneously start data acquisition. The same operation can also be carried out by selecting [Start all armed modules] from the station menu (see section 4.6, “Setting the Trigger Source/ Time Base Source/Arming”).

By using the arming signal, you can synchronize the modules even when there are no trigger inputs such as when using the 10-CH digital thermometer module WE7241 or when using the 10-CH, 100 kS/s digitizer module WE7251 in the free run mode.

IM 707003-01E

Note

When using bus trigger signal as an arming source, the pulse width of the bus trigger signal must be at least 50 µs.

2.3 How to Install Modules

Installation Method

WARNING

• Make sure to fasten the top and bottom attachment screws of the module. If you connect the input signal cable without fastening the attachment screws, the protective grounding (see page 2-9) provided by the power cord is compromised and may cause electric shock.

CAUTION

•To avoid damaging the instrument when installing modules, make sure to turn OFF the power switch of the measuring station according to the installing method given below.

• Be careful not to get your fingers caught in the eject lever when installing the module. Also, do not put your hand inside the slot, because you may injure your fingers on protrusions.

• Do not remove the cover plates from the empty slots. Doing so will cause overheating and malfunction. The cover plates are also needed to reduce electro-magnetic interference.

1. Verify that the power supply is not connected to the measuring station or the standby power switch or the main power switch is turned OFF. When installing an optical interface module into slot 0, make sure to turn OFF the main power switch (see page 2-10) on the rear panel. Measurement modules can be installed by turning OFF just the standby power switch (see page 2-11) on the front panel.

Switching the Power ON/OFF

CAUTION

• After turning OFF the main power switch on the rear panel, wait at least five seconds before turning ON the switch again. If you disconnect the AC plug while the main power switch is turned ON, you will also need to wait at least five seconds before reconnecting the AC plug again. Otherwise, the power supply section of the measuring station may become damaged.

• After turning OFF the standy power switch on the front panel, wait at least five seconds before turning ON the switch again. Otherwise, the measuring station or modules may not operate properly.

• There is a circuit breaker on the rear side of the measuring station WE800. If abnormal conditions are detected in the internal circuit, this circuit breaker will shutdown the power supply.

Installation and Connection

Note

• Before turning the power on, check that the measuring station is correctly installed and the power cord is correctly connected.

• If you hear the buzzer sounding intermittently and the measuring station enters the standby condition automatically, the cooling fan is not rotating. This is probably a malfunction. Contact your nearest YOKOGAWA dealer.

• If you turn the power ON immediately after turning it OFF, it will take approximately 2 seconds for the power to actually turn ON due to the circuit protection of the measurement module.

• If the “STANDBY” LED of the optical interface module does not turn ON when the main power switch is turned ON, check the points listed below. For safety reasons, turn OFF the main power switch in order to check the power cord connection and the supply voltage. If the LED still does not turn ON after checking these points, it is probably a malfunction. Contact your nearest YOKOGAWA dealer.

• Is the power cord connected properly?

• Is the power supply voltage within the rated supply voltage indicated on page 2-9?

• Is the optical interface module securely connected to the optical interface card?

• Is the optical interface module properly installed into the measuring station?

System Configuration

The following is an example in the case of connecting the measuring station and a PC to an Ethernet network at a time.

Ethernet (100BASE-TX)

Measuring station

100BASE-TX port

Network Configuration

Up to three measuring stations can be connected to each PC existing in the same subnet. Each PC and the measuring stations with which it will be communicating, are configured as one group. If there are multiple PCs that need to communicate with different triplet groups of measuring stations over the same Ethernet segment, multiple groups can be set. In this case, communication is possible only within the same group.

STP/UTP cable

. . .

DUT

Ethernet NIC

Ethernet

Group 1

Group 2

To reduce the amount of network traffic on a public use Ethernet network, the PC and the measuring stations can be connected via their own independent network. In this case, the PC and the measuring stations should be in the same IP subnet. For example, as shown in the following figure, each PC has two Ethernet NICs, one for connecting with other PCs and one dedicated for use with the WE7000 measuring stations. The two cards are configured with different IP addresses.

Ethernet for interconnecting PCs

Group 1

Ethernet dedicated for the WE7000

Group 2

Ethernet dedicated for the WE7000

Note

If there are multiple Ethernet NICs installed on a PC, you will specify which Ethernet NIC will be used to communicate to the WE7000 by specifying the IP address through the start option of the WE7000 Control Software (see section 3.6, “Configuring Ethernet Communications of the WE7000 Control Software.”

3.6 Configuring Ethernet Communications of the WE7000 Control Software

1. Select the [WE7000] shortcut icon and click the right mouse button.

2. Select [Properties], and click the [Shortcut] tab in the properties window that appears.

3. [... WE7000.exe" "-comm ethernet" ([ethernet95] in place of [ethernet] on Windows 95) is already entered in the [Target] textbox. Enter the following start parameters behind it. Separate each parameter with a space or a tab and close the parenthesis at the end. The parameters are not case-sensitive. Set all parameters except the IP address to be the same as the parameters written to the Fast Ethernet Module.

The “IP address” and “Subnet mask” can normally be skipped. However, they must be specified in the following cases (for details, see the Note below):

• When using Windows 95.

• When using multiple Ethernet NICs.

The group number is specified when multiple PCs and measuring stations are connected to the same network and you wish to avoid having multiple PCs controlling a particular measuring station. For information about groups, see “Network Configuration” on previous page. For changing the group of the measuring station, see “See Group” on page 4-8.

• IP address: IP = address of the PC (example: 192.168.21.128)

• Subnet mask: NETMASK = subnet mask (example: 255.255.255.0)

• Port number (can be omitted): PORTNO = port number (example: 34191 ¨ default setting)

• Group number (can be omitted): GROUPNO = group number (example: 0 ¨ default setting)

• Communication mode (can be omitted): COMPATIBLE = ON or OFF (example: ON ¨ default setting)

Entry example: "-comm ethernet IP=192.168.21.128 NETMASK=255.255.255.0

PORTNO=34191 GROUPNO=1 COMPATIBLE=OFF"

3-12

Note

• On Windows 95, the IP address and subnet mask must be specified. This is because the IP address and subnet mask that are assigned to the PC cannot be searched under the Windows 95 environment. When the IP address is automatically obtained through the DHCP server, the IP address is variable. Therefore, communications with the Fast Ethernet Module may not be possible, because the specified IP address and the IP address that is dynamically obtained may not match. To avoid this kind of problem, we recommend that you assign a fixed IP address to the PC instead of using the DHCP server in a Windows 95 environment.

• On Windows operating systems other than Windows 95 (Windows 98/NT 4.0/2000 Pro), the IP address and the subnet mask do not need to be specified if only one Ethernet NIC is installed. When multiple Ethernet NICs are installed, specify which card will be used by specifying the IP address of that card. You do not have to specify the subnet mask.

• If there is at least one Ethernet Module WE7051 in the same network, omit the communication mode parameter or specify “COMPATIBLE=ON.” If there are no WE7051 in the network and the COMPATIBLE dip switch is set to the “0” setting, make sure to specify “COMPATIBLE=OFF.”

4. Click the [OK] button.

IM 707003-01E

Page 48

3.7 Setting Ethernet Communication via USB

The procedure below is the configuring communication parameters when DHCP is not used. Connect the PC and the measuring station using the USB cable according to “Connecting the USB Cable” on page 2-8. If you are using the USB for the first time, install the USB driver (see section 3.3, “Installing the USB Driver”). Then, carry out the procedure below. If the [WE7000] shortcut icon for USB communication was already created when you set up the WE7000 Control Software and you are using the USB for the first time, install the USB driver and then carry out the procedure from step 5.

1. Select the [WE7000] shortcut icon and click the right mouse button.

2. Select [Properties], and click the [Shortcut] tab in the properties window that appears.

3. In the [Target] textbox, enter a space after [WE7000.exe"] followed by ["-comm USB"].

4. Click the [OK] button.

5. Turn ON both the main power switch and the standby power switch of the measuring station and double-click the [WE7000] shortcut icon.

6. Using the menu bar that appears, select [Set IP] from the [Network] menu to open the communication settings dialog box.

3-13

Page 49

3.7 Setting Ethernet Communication via USB

8. Select the [Fixed IP].

9. Set each parameter and click the [Setting] button. The default value of each parameter is as follows:

• IP address

Specify the IP address to assign to the measuring station. The default IP address is “192.168.21.3.”

• Subnet mask

Specify the mask that is used to determine the network address from the IP address. The default setting is “255.255.255.0.”

• Default gateway

Specify the IP address of the default gateway that is used when communicating with other devices on a different network. Specify “0.0.0.0” when there is no gateway. The default setting is “0.0.0.0.”

•Port number

Specify the port number of the process that receives UDP (User Datagram Protocol) packets of file transfers. The default setting is “34191.” This parameter is also needed when using DHCP, but no configuration is necessary if you are using the default settings.

Note

The IP address is used to distinguish between the various devices connected to the Internet which communicate using the TCP/IP protocol. The address is a 32-bit value normally expressed in four octets (each 0 to 255), each separated by a period as in 192.168.1.1. The IP addresses that are used over the Internet are managed by InterNIC. However, if the PC and measuring stations are connected over their own independent network as indicated in the bottom figure in section 1.1 “Network Configuration,” then IP addresses can be assigned arbitrarily within that network. The following three numerical ranges of IP addresses are provided for such use.

192.168.0.0 through 192.168.255.255, 172.16.0.0 through 172.31.255.255, and 10.0.0.0

through 10.255.255.255 As factory default, the WE7000 is set to use “192.168.21.0 to 192.168.21.255” which is contained in the first of the IP address ranges just described. If there are no existing devices that use IP addresses in the range “192.168.21.0 to 192.168.21.255,” and the PC and measuring stations are connected over their own independent network, then the factory default settings can be used.

If you change the settings, click [Setting]. If a confirmation dialog box opens, click [Yes]. This will restart the measuring station. The new settings are applied when the WE7000 restarts.

Next, to connect to Ethernet, carry out the steps below and follow the procedure given in “Network” (page 4-8).

1. Select [Exit] from the [File] menu to quit the WE7000 Control Software.

2. Remove the USB cable and connect an STP or UTP cable to the 100BASE-TX port for Ethernet communication.

To turn ON/OFF the standby power switch of a particular measuring station, select the appropriate measuring station in the [Station Name] list box.

Set Group

When using optical communications or the Ethernet network, the maximum number of measuring station that a single PC can control is three. If there are multiple PCs and measuring stations within a single network such as when connecting to an Ethernet network, you must specify which PCs will control each measuring station by assigning groups. If there are multiple PCs in the same group, multiple PCs will be able to control each station. This can lead to problems (current version of the software does not allow exclusive control). If you select “Set Group,” a group setting dialog box appears (see the figure on the next page). By factory default, all measuring stations are set to undefined group.

4-8

In the group setting dialog box, measuring stations belonging to [Group X] (where X≠0) that were specified by the start parameter of the WE7000 Control Software are shown under [Group X]. Measuring stations belonging to another group without a running PC* and measuring stations belonging to the undefined group are shown under [Others]. If the group number or the PC (controller) is [0], all measuring stations in other inactive PC groups and the undefined group are shown under [Group 0] and nothing is shown under [Others].

* For example, if a PC in “Group 1” is connected, the measuring stations of “Group 1” are

displayed only in the group setting dialog box of the PC in “Group 1.” They are not displayed in the group setting dialog box of “Group 2.”

To set a group, click the measuring station that you wish to set in the group setting dialog box, enter a group number (0 to 32767) in the [Group Number] entry box, and then click the [Update] button. Then, you must reset the main power switch of the measuring station that had its group number changed so that all PCs recognize the new group number.

Note

•You cannot set groups when using USB communication.

• The default group number of a PC (controller) is “0.” To change it, you specify it using the start option of the WE7000 Control Software (see “Start Installation” in section 3.2, “Installing the WE7000 Control Software.” You cannot change the group number in the group setting dialog box. If you are using optical communications, the start option is specified as “-comm optical devicename= WE7036 GROUPNO=1” (when specifying group 1), for example. Similarly for Ethernet communications, add “GROUPNO=1” to the other start options.

4.8 Saving Waveform Data/Converting Files

On measurement modules that acquire data, the timing for starting/stopping the saving of the measured data that is displayed on the waveform monitor can be controlled by specifying the time or using triggers. In addition, when measured data is continuously acquired using modules such as the thermometer module, continuous saving of the data is possible.

Limitations

• Controlling of the data save operation by specifying a time is valid on all modules. Trigger control is valid only on the following modules with the indicated software version.

WE7231 (Ver. 3.05 or later), WE7235 (Ver. 3.01 or later), WE7241 (Ver. 3.15 or later), WE7245 (Ver. 3.04 or later), WE7251 (Ver. 3.06 or later), WE7271/WE7272 (Ver. 3.07 or later), WE7273 (Ver. 3.01 or later), WE7275 (Ver. 3.07 or later), and WE7521 (Ver. 3.04 or later)

• Save operation using gates is valid only on the following modules with the indicated software version.

WE7231 (Ver. 3.05 or later), WE7241 (Ver. 3.15 or later), WE7235 (Ver. 3.05 or later), WE7245 (Ver. 3.05 or later), WE7251 (Ver. 3.08 or later), WE7271/WE7272 (Ver. 3.08 or later), and WE7275 (Ver. 3.08 or later)

4.8 Saving Waveform Data/Converting Files

Selecting the File Format for the Saved Data

Select ASCII data in CSV format or binary data in YOKOGAWA’s proprietary file format (file extension: .wvf). The file size is smaller for the binary data.When saving to ASCII data, you can select whether to add time axis data. However, if the start/stop condition is set to [Trigger (Alarm)] or the [File save method] is set to [Every Trigger], you cannot save to ASCII Data.

In addition, a header file (extension: .hd1) containing information needed in analyzing the saved data, is created when the waveform data is being saved. This header file is in ASCII format. For details, request for technical information.

Setting Save Method

Select from the following two choices.

• Cyclic You specify the number of files and the data are saved in a cyclic fashion among the specified number of files until the measurement is stopped. The newest data exits in the file to which the data was saved immediately before the measurement stopped.

Setting the Save Method During Free Run Mode

When continuously acquiring waveform data as when using a thermometer module, select whether to save the data to one file or divide the data among multiple files according to the specified number of data points. When saving to multiple files, set the number of files you are going to save. Also, set the specified number of data points for each file to the number of data points per channel. When saving to multiple files, the save operation stops upon saving data to the specified number of files.

Starting/Stopping the Save Operation and Setting Waveform Monitor ON/OFF

The save operation starts upon starting the measurement (clicking [Start] on the operation panel, selecting [Start] from the [Global] menu of the menu bar), clicking [Start] on the menu bar, or clicking [Start/Stop saving of measured data] on the waveform monitor. If the measurement is stopped, the save operation is temporarily suspended. But if the measurement is started again, the save operation also resumes. To stop the save operation, click the [Stop] button on the operation panel, select [Stop] from the [Global] menu of the menu bar, click the [Stop] button on the menu bar, or click [Start/Stop saving of measured data] on the waveform monitor. Normally, the waveform monitor is displayed when the measurement is started. However, displaying the waveform while saving the waveform data causes the waveform acquisition period to be longer. If you wish to prevent the acquisition period from degrading, set the [Waveform monitor ON/OFF] button, located to the right of the [Start] button on the operation panel, to the OFF setting.

4.9 Assorted Module Binding Function

This section describes the assorted module binding function that allows waveforms of different types of modules to be combined and displayed on a single monitor and measured data to be saved to a single file.

Limitations

The following limitations exist in the assorted module binding function.

• Recommended PC and memory: Pentium II 400 MHz or higher*, 128 MB or more * Depending on which combination of modules are used, the WE7000 may not

operate properly unless the PC's processor exceeds this speed.

• Applicable modules: WE7081, WE7231 (Ver. 3.05 or later), WE7235, WE7241, WE7245, WE7251, WE7271/WE7272/WE7273, WE7275, and WE7521 (Ver. 3.03 or later) within the same measuring station.

• Only ten types from the above modules are selectable.

• Only a single Waveform Monitor can display waveforms of bound modules.

• Acquisition mode of the applicable module: Select trigger mode or free run mode for all applicable modules. (If you select trigger mode, WE7231 and WE7241 is not applicable.)

•Waveform data of a module with a long sampling interval when the sampling interval is different: Pulse interpolation is performed on the deficient data.

•Time base: Select internal or external clock for all applicable modules.

• Modules that are specified for the assorted module binding function cannot display the Waveform Monitor or save the measured data by itself. In addition, the operation panel can be opened, but some items cannot be specified.

• The digitizer modules (WE7251/WE7271/WE7272/WE7273/WE7275), the strain module (WE7245), and the timing measurement module (WE7521) can increase the maximum record length by reducing the number of the measurement channels. However, this function cannot be used during assorted module binding. In addition, the function that enables you to specify a 1-kHz input filter on the WE7251 Digitizer Module cannot be used during assorted module binding.

• The WE7521’s time stamp mode cannot be used.

• The WE7521’s data hold setting will be set to ON.

• Sampling Interval

To use the same sampling interval on both modules for making measurements, select the [Link Sampling Interval] check box and choose the sampling interval from the [Sampling Interval] list box. However, the actual interval used by the module for making measurements is the sampling interval corresponding to the specification of each module. If a sampling interval that does not exist in the specifications of one module is selected, the data over the interval in which measurements are not made is interpolated using the previous value. To specify the sampling interval for each module separately, clear the [Link Sampling Interval] check box and select the interval using the [Sampling Interval] list box in the module-specific setup section. The maximum allowable difference of sampling intervals between the modules is 1000 times.

•Time Base

If you selected the external clock (BUSCLK), you must select the time base source (CMNCLK) in the trigger source/time base source/arming setting dialog box that appears by clicking the Trigger button on the menu bar.

The items that cannot be specified during assorted module binding are shaded. In addition, you cannot change the settings while measurement is in progress. Clicking Start on the Bound Module operation panel closes the panel.

• Precautions to be taken during operation

• The start of measurement may be offset by up to 60 ms between modules.

• If the time base is set to external clock (BUSCLK), set the period of the external

clock according to the specifications of the module that is to use the external clock.

• If the time base is set to Internal, displayed data from the WE7231 Fast Digital

Thermometer Module or WE7521 Timing Measurement Module may be erroneous by up to 0.8 s/h along the time axis relative to the other bound modules. Please be aware of this when performing continuous measurement in Free Run mode.

•Trigger Bus Since the same trigger signal is used by the target modules through this function, either the BUSTRG1 or BUSTRG2 trigger bus is occupied by this function. The manual trigger of the occupied trigger bus cannnot be used. Use the [Trigger Bus] list box to make the selection. These settings are applied to the “trigger source/time base source/arming setting” at the start of the measurement. If the trigger source is not BUSTRG and if a module that is not a target module of the assorted module binding is outputting the trigger signal to the trigger bus, the setting is made invalid at the start of measurement. In this case, the settings are not set back even if you stop the measurement.

• Record length The selectable record length varies depending on the selectable sampling intervals of the target modules as following below. And even at the ranges shown below, it is only possible to set a record length such that data can be acquired at a measurement interval of 5 ms or more. WE7251: 100 to 100 k points, WE7245/WE7271/WE7272/WE7273/WE7521: 100 to 1 M points, WE7081/WE7275: 100 to 2 M points

• Pretrigger The selectable range of pretrigger varies depending on the specified sampling interval and record length.
