SetupA VISA library is required to use the software application. The VISA library (any one of NI-VISA, AgilentVISA, and KI-VISA) must be installed in the controller (Windows).

Installing the VISA LibraryVISA (Virtual Instrument Software Architecture) is a specification for a standard software forconnecting instruments that was defined by the VXIplug&play Systems Alliance.One of the VISA libraries (driver software implemented in compliance with the VISAspecifications) below is necessary. Older version of VISA libraries does not support USB.NI-VISA by National Instruments (Ver. 3.2 or later)Agilent VISA by Agilent Technologies (Agilent IO Libraries M01.00 or later)KI-VISA Ver. 3.0.x or later

Installing KI-VISA

KI-VISA is Kikusui's original VISA library that supports VXIplug&play VISA Specifications.The newest version can be downloaded from Kikusui website(https://www.kikusui.co.jp/en/download/).KI-VISA is not required if NI-VISA or Agilent VISA is already installed.

1. Open the ki-visa folder in the CD-ROM.

2. Double-click kivisa_5_5_x.exe in the folder to run it.For 32-bit operating systems, install kivisa_5_5_x_(x86). For 64-bit operating systems,install kivisa_5_5_x_(x64).

3. Proceed with the installation according to the instructions on the screen.

NOTE

kivisa_5_5_x(x64).exe contains two software packages, KI-VISA (x64) and KI-VISA (WOW64).When KI-VISA (x64) has been successfully installed, the installation of KI-VISA (WOW64)begins. Be sure to confirm that the installation of KI-VISA (WOW64) has finished successfully.













Setup

Interface SetupThe factory default remote control interface setting is GPIB. The GPIB, RS232C, and USBinterfaces cannot be used simultaneously.

Overview of MessagesThe information that is exchanged between the controller (computer) and the device (PLZ-4W/PLZ-4W L/PLZ-4WH) is called a message.The PLZ-4W/PLZ-4WL/PLZ-4WH uses the SCPI language for the messages.There are two types of messages, commands that are sent from the computer to the PLZ-4W/PLZ-4WL/PLZ-4WH and responses that are sent from the PLZ-4W/PLZ-4WL/PLZ-4WH tothe computer.

Command hierarchySCPI commands are ASCII-based commands designed for test and measurement devices.The command hierarchy is structured around the common root or node, which is theconstruction block of the SCPI sub system. A command consists of a program header,parameters, and punctuations.The hierarchy is explained using the SOURce subsystem as an example.

Program header Parameter Hierarchy of nodeSOUR: Roote node PULSE Second level

[:STAT] {OFF|ON} Third level:DCYC <numeric> Third level:LEV Third level [:VAL] Fourth level

:COND <bool> Fifth level

A higher node is separated from a lower node using a colon (:).

Command SyntaxThis manual denotes SCPI commands using the following format.

MEASure[:SCALar]:CURRent:DC?

SCPI commands can be issued using the short form. The short form of a SCPI command isthe section of the command written in uppercase.SCPI commands can be sent in the long form or short form. Since SCPI commands are notcase-sensitive, CURR, Curr, and curr are all accepted as the short form of CURRent. In thelong form, CURRENT, Current, and current are all acceptable.

• A space is required between the program header section and the parameter section.• Multiple parameters, when available, are concatenated using commas.• Commands are concatenated using semicolons (compound command).

SOURce:CURRent MINimum;VOLTage MINimum

In the second command, SOURce is omitted. This is because the path is set to SOURce bythe first command SOURce:CURRent MINimum.This compound command is the same as entering the following commands.SOURce:CURRent MINimum

SOURce:VOLTage MINimum

An error occurs if a node that is not defined in the current path is designated.Commands of different subsystems can be concatenated using a colon and a semicolontogether.SOURce:CURRent MINimum;:MEASure:CURRent?

This compound command contains two root nodes, SOURce and MEASure.When the second or subsequent command starts with a colon, the path specified by theprevious command is cleared.

• The maximum number of characters that can be transmitted in a single line is 256.













Special symbols

Special symbols used in this manual to describe SCPI commands are defined below.• Characters and numbers delimited by "|" in braces indicate that one of the items is to beselected.

Do not include the braces in the actual program.• The characters <> indicate program data.

Do not write <> in the actual program.• Brackets indicate option data.

When option data is not sent with the program, the default value is applied.Do not write [ ] in the actual program.

Queries

The device settings or status can be queried.To make a query, add a question mark at the end of the program header section.If a query has parameters, enter a space after the question mark followed by theparameters.

SOURce:CURRent? MIN

ResponseA response returned as an answer to a query. It is a message that is always sent from thedevice to the computer. The status of the device or measured values are transmitted to thecomputer.

NOTE

When transmitting two queries in separate lines, read the response to the first query beforetransmitting the second line.

• GPIB and USBWhen two query lines are sent at once, a SCPI error (-410, "Query INTERRUPTED") may occur.

• RS232CWhen two query lines are sent at once, an incomplete response may be received for the firstquery followed by a complete response for the second query.

String termination

All commands must be terminated using a valid terminator.The available terminators are <new line> (ASCII 0x0A) and EOI (end-or-identify). Eitherone can be used as a terminator.EOI is not available on the RS232C. Be sure to use <new line>.EOI is also not available on the USB. However, a terminator separate from <new line> isautomatically added. It does not matter whether <new line> is added or not.When a command string is terminated, the path is reset to the root level.

NOTE

CR (ASCII 0x0D) is not a terminator.

Common commandsThe IEEE-488.2 and SCPI standards contain a set of common commands for reset, self-test,and other functions. These common commands always start with an asterisk. Thecommands may have one or multiple parameters.

Overview of Messages

ParametersThe parameter format of SCPI is derived from the program parameter format defined inIEEE 488.2.The representation system of the program data that the PLZ-4W/PLZ-4WL/PLZ-4WH handlesis indicated below.

Non-numeric parameters

String dataString data is used when a series of ASCII characters are requested.Enclose a string in single quotations or double quotations. The start and end quotationmarks must match.

PROGram:MEMO "My program"

If you wish to use a quotation mark as a part of the string, enter two quotation marksconsecutively (with no characters in between).

Character dataCharacter data is used when only a limited number of values is available for the programsetting. Responses are returned in the short form.

POWer:RANGe {LOW|MEDium|HIGH}

Boolean dataBoolean data expresses a 1 or 0 condition or an ON or OFF condition. Responses arereturned as 1 or 0.

FUNCtion:CTIMe {ON|OFF|1|0}

Numeric parameters

R1Represents an integer.Details are given in the IEEE 488.2 Standard Digital Interface for ProgrammableInstrumentation.

NR2Represents a real number (floating point).Details are given in the IEEE 488.2 Standard Digital Interface for ProgrammableInstrumentation.

NR3Represents a real number (exponential).Details are given in the IEEE 488.2 Standard Digital Interface for ProgrammableInstrumentation.The value +3.80000+E02 is returned for the response data 380. The number of digits to theright of the decimal is 5.

NRfNRf is a generic term that includes NR1, NR2, and NR3.













NumericA numeric parameter such as a decimal point, optional prefix, or measurement unit.The syntax as a numeric representation is the same as NRf.MINimum and MAXimum are available as substitutes for declaring certain values.Units such as V, A, and W can also be used in a numeric parameter.If a value that cannot be assigned is entered, the device rounds the value to the closestpossible value.

PULS:DCYC 100

Return 95 in response to PULS:DCYC? as switching duty cycle is 0 to 95.

Special form numeric parameter

The special form numeric parameters MINimum, MAXimum and DEFault can be used assubstitutes for limit values when the parameter is numeric. In the example below, thecurrent limit is set to the minimum value.

SOURce:CURRent MINimum

The minimum and maximum values can be inquired for most parameters using queries.SOURce:CURRent? MIN

SOURce:CURRent? MAX

Measurement unit

Below are the default measurement units. ·V (voltage) ·A (current) ·OHM (resistance) ·SIE (conductance) ·W (wattage) ·HR (hour) ·MIN (minute) ·S (second) ·A/US (current/time) ·PCT (percent)

The following optional prefixes are supported.

·M (milli) ·K (kilo) ·U (micro)

NOTE

• The unit symbols in the International System of Units (SI) contain lowercase characters. TheIEEE standard uses uppercase characters. SCPI commands are not case-sensitive.

• Commands are accepted even if a measurement unit are not specified.

• To enter "µ" in the data, use "U" instead.

Tutorial

Detecting the measurement completionThe *OPC? query sets an ASCII character 1 when all standby procedures are completed.During this period, response data cannot be retrieved. If another command is used withoutretrieving the response data, the query is considered to have been aborted and OQAS(Operation Complete Query Active State) is reset. If this happens, an ASCII character 1 willnot be set unless the *OPC? query is sent again.The *OPC command sets the OPC bit (bit 0) of the standard event status register to truewhen all operations in standby are complete. If the standard event status enable register orthe service request enable register is set, this event can be transmitted to the servicerequest (SRQ). If the *CLS command is sent before the OPC bit is set, OCAS (OperationComplete Command Active State) is reset by the *CLS command. If this happens, the OPCbit is not set unless the *OPC command is sent again.

For example, if a command sequence such asINIT;*OPC;*CLS

is sent, the last *CLS command cancels the *OPC command. The *CLS command does notabort measurement actions that have been initiated. It does not have the functionality ofaborting measurements.

The MEAS? query start measurements and query the measured data. The response data inresponse to these queries are generated when the measurement is complete. Thischaracteristic can be used to detect the standby process by carrying out receive operation ofthe response data.

The *WAI command stops the processing of all subsequent commands until all procedures instandby are completed. This means that once this command is sent, the measurementcannot be aborted with the ABOR, *RST, or *RCL command. The only exception is theIEEE488.1 sdc and dcl messages. These messages can abort procedures in standby byinterrupting the *WAI command. (The sdc and dcl messages (device clear messages) canonly be used on the GPIB and USB. A corresponding function is not available on the RS232C,but the PLZ-4W/PLZ-4WL/PLZ-4WH operates in the same manner when it receives a breaksignal.)

Tutorial

Operation using a software triggerThe PLZ-4W/PLZ-4WL/PLZ-4WH can synchronize the output changes using triggers.If ABOR is sent or if the conductance (COND), current (CURR) or status of the load(INP/OUTP) setting is changed, the values to which the target conductance, current andstatus of the load are to change using a trigger are cancelled.Table below shows the setting value when the current is set to 20 A (CURR 20) and whenthe target value to which the current is to change using a trigger is set to 10 A (CURR:TRIG10).

Response

CURR? CURR:TRIG setting value

Immediately after the setting 20 10

After a trigger is sent 10 60

After *RST is sent 0 0

ABOR is sent before sending a trigger 20 20 (cancel)

Voltage change CURR 15 is sent before sending a trigger 15 15 (cancel)

State

The following two states (IDLE state and INITiate state) are available in the trigger function.

IDLE stateWhen the PLZ-4W/PLZ-4WL/PLZ-4WH is turned on, the trigger function is in the IDLEstate. In this state, the trigger function ignore all triggers. Sending one of the followingcommands at any time also returns the trigger function to the IDLE state.The sequence does not start in the IDLE state, even when TRG is sent.ABORt

*RST

*RCL

IEEE488.1 sdc (Selected Device Clear) or dcl (Device Clear)

INITiated stateIf INIT is sent in the IDLE state, the trigger function starts and the PLZ-4W/PLZ-4WL/PLZ-4WH enters the INITiated state. If a trigger is sent, setting is started.

Operation

If auto continue mode is turned on (INIT:CONT ON), measured data is automaticallyrefreshed without having to send the INIT command each time.













When the operation is completed, the trigger function returns to the IDLE state again. Whenan ABOR or an equivalent command is sent without executing the trigger, the triggerfunction returns to the IDLE state.

Tutorial

Error Checking

Error/Event Queue

The SCPI specifications define a standard error reporting scheme --- Error/Event Queue.This is a FIFO (First In First Out) queue, which records errors and events. The maximumnumber of errors/events that can be recorded in the PLZ-4W/PLZ-4WL/PLZ-4WH is 255.Each error/event can be read by the SYSTem:ERRor query.

SYSTem:ERRor?

The response to this query contains a numerical part (error/event number) and a textualdescription, such as:

-222,"Data out of range"

The error/event queue is empty when the *CLS common command is sent, when the lastitem in the queue is read, or when the PLZ-4W/PLZ-4WL/PLZ-4WH is turned on. When theerror/event queue is empty, the query returns the following:

0,"No error"

Tutorial

Visual Basic 2008Communicate with the PLZ-4W/PLZ-4WL/PLZ-4WH series using VISA through GPIB,RS232C, or USB.

Setting the "Project"

At first, set the communication driver (VISA liabrary) for the "Project".Click "Project" on the menu bar, then select "Add Reference" to refer "VISA COM 3.0 TypeLibrary".

Communication through GPIB, RS232C, or USB

After setting the communication driver, it enables to communicate by GPIB, RS232C, orUSB.The following describes the communication procedure for via VISA.













Open the VISATo communicate with the device of GPIB, RS232C, or USB via VISA, it requires to open theVISA first. When opening the VISA, specify the I/O resource.

Example : To open VISA by using USBSet rm = CreateObject("VISA.GlobalRM")

Set msg = rm.Open("USB::0x0B3E::0x1019::00000001::INSTR", NO_LOCK, 0, "")

"USB::0x0B3E::0x1019::00000001::INSTR" is the I/O resource.The I/O resource is specified by the following constructions. The part indicated with [ ] canbe abbreviated. Enter the appropriate value in the part specified in oblique characters.

GPIB GPIB[board]::PrimaryAddress[::SecondaryAddress][::INSTR]Example : The primary address 3 of the measuring instrument connected to GPIB0.GPIB0::3::INSTR

Serial(RS232C)

ASRL[board][::INSTR]Example : The measuring instrument connected to the serial port COM1.ASRL1::INSTR

USB USB[board]::VendorID::ProductID::SerialNumber[::InterfaceNumber][::INSTR]Example : The USNTMC measuring instrument having with the vendor ID (VID)2878,Product ID(PID)4121 and serial number "00000001".USB0::0x0B3E::0x1019::00000001::INSTR

For VISA, the alias can be used for the I/O resource.When using the alias for the I/O resource, even the alias name to be hard coating directly inthe application, it can be easily converted to the appropriate I/O resource name.

Example : When using the alias (MYPIA) for the I/O resource.Set msg = rm.Open("MYPIA", NO_LOCK, 0, "")

When the alias is used, the actual I/O resource is specified by such an external configurationtable. When using the USB (example for KI-VISA)

In case of using VISA other than KI-VISA, please refer to the applied VISA manual.

Status Register and Status Report FunctionIEEE488.2 and SCPI registers are used for the status reports.In each SCPI status register, there are sub registers, CONDition register, EVENt register,ENABle register, PTRansition filter, and NTRansition filter.The SCPI status register structure as shown in the figure below. The character "+"represents the logic sum of the register bits.

Architecture

CONDition registerThe transition of the CONDition register is automatic and reflects the condition of the PLZ-4W/PLZ-4WL/PLZ-4WH in real-time. Reading this register does not affect the contents.

EVENt registerThe EVENt register bits are automatically set according to the changes in the CONDitionregister. The rule varies depending on the positive and negative transition filters(PTRansition and NTRansition). The EVENt register is reset when it is read.

ENABle registerThe ENABle register enables the reports to the summary bit or status bit of the event bit.

Transition filterUse the PTRansition (positive transition) filter to report events when the condition changesfrom false to true.Use the NTRansition (negative transition) filter to report events when the condition changesfrom true to false.If both the positive filter and the negative filter are set to true, events can be reported eachtime the status changes.If both filters are cleared, event reporting is disabled.
