RIGOL Chapter 1 Programming Overview

LAN USB DEVICE RS232

To Build Remote Communication

You can build the remote communication between DP800 and PC over USB, LAN, RS232 or GPIB (option, can be extended via the USB-GPIB interface converter) interface.

Note: The end mark of the command sent through RS232 interface is "\r\n".

Operation Steps: 1 Install the Ultra Sigma common PC software

You can acquire this software from the resource CD in the standard accessories or download it from RIGOL official websit e (

2 Connect the instrument and PC and configure the interface parameters of the instrument

DP800 supports USB, LAN, RS232 and GPIB (extended via the USB HOST interface of the instrument) communication interfaces, as shown in the figure below.

www.rigol.com) and then install it according to the instructions.

USB HOST

Figure 1-1 DP800 Communication Interfaces

Note: For DP831A/DP832A/DP821A/DP811A, the instrument is installed with the LAN and RS232 options when it leav es factory; users can build the remote communication between the instrument and PC via the LAN or RS232 interface directly. For DP831/DP832/DP821/DP81 1, the LAN interface communication and RS232 interface communication are optional functions; to use the functions, please order the corresponding option and install the option correctly (

(1) Use the USB interface: connect the USB DEVICE interface at the rear panel of DP800 and the USB

HOST interface of the PC using USB cable.

(2) Use the LAN interface:

 Make sure that your PC is connected to the local network.  Check whether your local network supports DHCP or auto IP mode. If not, you ne ed to

acquire the network interface parameters available, including the IP address, subnet mask, gateway and DNS.

 Connect DP800 to the local network using network cable.  Press Utility  I/O Config  LAN to configure the IP address, subnet mask, gateway and

DNS of the instrument.

:LIC:SET).

Chapter 1 Programming Overview RIGOL

(3) Use the RS232 interface:

 Connect the RS232 interface with the PC or data terminal equipment (DTE) using RS232

cable.

 Press Utility  I/O Config  RS232 to set interface parameters (such as the baud rate

and parity) that match the PC or terminal equipment.

(4) Use the GPIB interface:

 Use the USB-GPIB interface converter to extend a GPIB interface via the USB HOST interface

at the rear panel o f DP800.

 Connect the instrument with your PC using a GPIB cable.  Press Utility  I/O Config  GPIB to set the GPIB address of the instrument.

3 Check whether the connection is successful

Run the Ultra Sigma, search for resource, right-click the resource name and select "SCPI Panel Control" in the pop-up menu. Enter the cor rect command in the pop-up SCPI control panel and click "Send Command" and then "Read Response" or click "Send & Read" directly to check whether the connection is successful.

Remote Control Methods

1 User-defined Programming

You can program and control the instrument using the SCPI (Standard Commands for Programmable Instruments) commands listed in chapter 2 "Command System" in various development environments (such as Visual C++, Visual Basic and LabVIEW). For details, refer to the introductions in chapter 4 "Progr amming Demos".

2 Send SCPI Commands via the PC Software

SCPI (Standard Comm ands for Programmable Instruments) is a standardized instrument programming language that is built upon the standard IEEE 488.1 and IEEE 488.2 and conforms to various standards (such as the floating point operation rules in IEEE754 standard, ISO646 7-bit coded character for information intercha nge (equivalent to ASCII programming)). This section introduces the syntax, symbols, parameters and abbreviation rules of the SCPI commands.

Syntax

SCPI commands present a hierarchical tree structure and contain multiple subsystems, each subsystem consists of a root keyword and one or more sub-keywords. The command string usually starts with ":"; the keywords are separated by ":" and are followed by the parameter settings available. The command keywords and the first parameter are separated b y a space. "?" i s added at the end of the comman d string to indicate query.

For example, :SYSTe m:COMMunicate:LAN:IPADdress <ip> :SYSTem:COMMunicate:LAN:IPADdress?

SYSTem is the root keyword of the command. COMMunicate, LAN and IPADdress are the second-level, third-level and forth-level keywords respectively. The command string starts with ":" which is also used to separate the multiple-level keywords. <ip> represents the parameters available for setting. The command

DP800 Programming Guide 1-3

RIGOL Chapter 1 Programming Overview

keywords :SYSTem:COMMunicate:LAN:IPADdress and parameter <ip> are separated by a space. "?" represents query.

"," is generally used for separating multiple parameters contained in the same command, for example, :DELAY:PARAmeter <secnum>,{ON|OFF},<time>

Symbol Description

The following four symbols are not the content of SCPI commands and will not be sent with the commands. They are usually used to describe the parameters in the commands.

1 Braces { }

Usually, multiple optional parameters are enclosed in the braces and one of the parameters must be selected when sending the command. For example, :DISPlay:MODE {NORMal|WAVE|DIAL}.

2 Vertical Bar |

The vertical bar is used to separate multiple parameters and one of the parameters must be selected when sending the command. For example, :DISPlay:MODE {NORMal|WAVE|DIAL}.

3 Square Brackets [ ]

The content (command keyword) enclosed in the square brackets can be omitted. When the parameter is omitted, the instrument will set the parameter to its default. For example, for the :MEASure[:VOLTage][:DC]? command, sending any of the four commands below can achieve the

same effect. :MEASure? :MEASure:DC? :MEASure:VOLTage? :MEASure:VOLTage:DC?

4 Triangle Brackets < >

The parameter enclosed in the tri ang le br ack ets m us t be replac ed by an ef fec tive valu e. F o r examp le,

send the :ANALyzer:CURRTime <value> command in :ANALyzer:CURRTime 5 form.

Parameter Type

The parameters of the commands introduced in this manua l contains 5 types: bool, integer, real number, discrete and ASCII string.

1 Bool

The parameter could be "ON" (1) or "OFF" (0). For example, :RECorder[:STATe] {ON|OFF}.

2 Integer

Unless otherwise noted, the parameter can be any integer within the effective value range. Note that do not set the parameter to a decimal; otherwise, errors will occur. For example, in the :SYSTem:BRIGhtness <brightness> command, <brightness> can be any integer from 0 to 100.

3 Real Number

Unless otherwise noted, the parameter can be any real number within the effective value range.

For example, for CH1 of DP831A, the ranges of <volt> and <curr> in the :APPLy CH1,<volt>,<curr>

command are 0.000V to 8.400V and 0.0000A to 5.3000A respectively.

4 Discrete

The parameter could only be one of the specified values or characters. For example, in the :ANALyzer:OBJect {V|C|P} command, the parameter can be V, C or P.

1-4 DP800 Programming Guide

Chapter 1 Programming Overview RIGOL

5 ASCII String

The parameter should be the combinations of ASCII characters. For example, in the :MMEMory:STORe <file_name> command, <file_name> is the filename of the f ile to be saved and can include Chinese characters, English characters and numbers.

Besides, many commands contain the MINimum and MAXimum parameters which are used to set the parameter to its minimum or maximum value. For example, MINimum and MAXimum in the :SYSTem:BRIGhtness {<brightness>|MINimum|MAXimum} command are used to set the brightness to the minimum or maximum.

Command Abbreviation

All the commands are case-insensitive and you can use any of them. If abbreviation is used, all the capital letters in the comman d must be written c ompletely. For example, the :ANALyzer:ANALyze command can be abbreviated to :ANAL:ANAL.

SCPI Status Registers

All the SCPI instruments execute the status register operations in the same way. The s tatus system reco rds the various instrument states into three register sets: status byte register, standard event register and questionable status register sets. The status byte register records the advanced summary information reported by other register sets. The SCPI status systems of the DP8 00 series multi-channel models (take DP831A as an example) and single-channel model (take DP811A as an example) are as shown in Figure 1-2 and Figure 1-3 respectively.

Event Register

The event register is r ead-only and is used to report some states of the power supply defined internally. All the bits in the event register are latched and once an event bit is set, the later state (state of the event represented by this bit) changes will all be ignored. The event register bits will be cleared automatically when you send command to query the ev ent register (such as th e command) or send the the bits in the event register. When querying the event register, the query returns a decimal value corresponding to the sum of the binary weights of all the bit s in the register.

*CLS command to clear the register, but the reset command (*RST) will not clear

Enable Register

The enable register is both readable and writable. It is used to define which status i nform ation will be reported to the next-level. The bits in the enable register will not be cleared when you send command to query the enable register or send the can clear the bits in the event register). To enable the bits in the enable register, you need to write into the register a decimal value corresponding to the sum of the binary weights of the bits to be enabled in the register.

*CLS command to clear the register state (but the *CLS command

Multi-logic Output

This part is only applicable to multi-channel models. T ake DP831A as an exampl e. The 3-logic output of the power supply includ es a channel questionable status register and three independent channel questionable status SUMMARY registers (corresponding to the logic outputs of the three channels respectively). The channel questionable status SUMMARY registers report the sta tus of each channel to the channel questionable stat us register which then reports the channel status to the bit13 (ISUM bit) of the

Questionable Status Register

Questionable Status Register of Multi-channel Models

The SCPI status system of the multi-channel models is as shown in Figure 1-2. Wher ein, the channel questionable status register indicates in which channel questionable event occurs. While for each specific logic output, the channel questionable status SUMMARY register is a pseudo-questionable status register.

The questionable status register provides information about the questionable status of the power supply. Bit4 (TEMPerature) reports the over-temperature state; bit11 (FAN) reports the fan failure state and bit13 (INSTrument summary) summaries the questionable output state of any of the three output channels. You can send the first enable the register the information of which you want to summarize using bit13. Send

:STATus:QUEStionable:INSTrument:ENABle command to enable the chan nel questionable status
