Chapter 1 Before Using the API

1.1 Introduction to Functions

Supported ModelsThis software provides the API (Application Programming Interface) that supports

the MX100 and DARWIN, and the extension API that makes the main API easier to

use.

MX100: All models

DARWIN: All models (DA, DC, and DR). However, the Ethernet communication

function (Ethernet module) is required.

Supported LanguagesLanguages supported by the API: Visual C++, Visual C, and Visual Basic

Languages supported by the extension API:

Visual C++, Visual C, Visual Basic, Visual

Basic.NET, and Visual C#

Functions for the MX100Communication Functions

Functions used to communicate with the MX100 via the Ethernet interface.

Setup FunctionsFor configuring the MX100, modules, and channels. However, CAN Bus Module

hardware settings are not supported. For hardware settings, use the software that

came with the module.

Data Retrieval Functions• Retrieval of measured data using FIFO

Retrieves the most recently measured data via the FIFO (first-in first-out) buffer.

Also retrieves instantaneous values. The retrieval interval of instantaneous values

is 100 ms or more.

• Retrieval of measured data by channel

Retrieves the most recent measured data of the specified channel. Also retrieves

instantaneous values. The retrieval interval of instantaneous values is 100 ms or

more.

• Retrieval of setup data

Retrieves the system configuration of the MX100, network information such as the

IP address, and setup data related to channels.

• Collective retrieval of DO (digital output) data

Collectively retrieves the ON/OFF status of the DO.

• Retrieval of channel information data (channel number, etc.)

• Retrieval of AO/PWM data

Retrieves data that shows the AO/PWM channel output.

1-2 IM MX190-01E

• Retrieval of transmission output data

Data that indicates the AO/PWM channel transmission status.

When data is retrieved, it indicates the status of the current transmission output.

When data is sent, it is the specification that controls the start and stop of the

transmission output.

Control Functions• Date/time setting

• Setting of the backup function that saves the measured data to the CF

card, and formatting of the CF card

• Initialization and reconfiguration of the system (unit)

• Resetting of alarms (acknowledge alarm)

• Designation of the information displayed on the 7-segment LED

UtilitiesProvides functions for converting measured values into character strings, retrieving

error message strings, and other utility functions.

Functions for DARWINThe API provides functions that are equivalent to the DARWIN communication

functions. Some of the basic functions of the DARWIN communication functions are

provided as API classes (for Visual C++) or functions (for Visual Basic, Visual C,

Visual Basic.NET, and C#). Other functions can be implemented using the

commands of the DARWIN communication function.

Functions Provided by this Software

• Communication FunctionsFunctions used to communicate with DARWIN via the Ethernet interface.

• Setup FunctionsSets the measurement range and alarms.

• Data Retrieval Functions• Retrieval of the measured data

Retrieves measured data in ASCII or binary format. The values are instantaneous

values.

1• Retrieval of setup dataRetrieves the setup data of the operation mode, basic setting mode, and A/D

calibration mode.

• Retrieval of channel information data (channel number, etc.)

• Control Functions• Date/time setting

• Reconfiguring the system

• RAM clear (initialization of operation mode parameters)

• Alarm reset

• Setting mode switching

• UtilitiesProvides functions for converting measured values into character strings, retrieving

error message strings, and other utility functions.

Implementing Functions Corresponding to the Commands of the DARWIN

Communication FunctionFunctions corresponding to commands of the DARWIN communication function can

be implemented according to the procedure below.

• Visual C++: Create an inheritance class of CDAQDARWIN and add member

functions that execute the commands of the DARWIN communication function

using the runCommand member function.

• Visual C and Visual Basic: Create functions that execute the commands of the

DARWIN communication function using the runCommandDARWIN function.

• Visual Basic.NET/C#: Create functions that execute the commands of the

DARWIN communication function using the runCommandDA100 function of the

extension API.

Notes• The user program needs to be recompiled and re-linked because the structure

and other aspects of the API R3.01 were changed.

1.2 Software Components and Features

Software ComponentsThe software consists of the API and an extension API.

The software provides Visual C++ classes.

The classes are Common Class, MX100 class, and DARWIN class. The MX100

Class and DARWIN Class are derived from the Common Class.

Functions used by Visual C, Visual Basic, Visual Basic.NET, and C# are provided.

Functions for the MX100 and functions for DARWIN are also available. These

functions are executed by calling the Visual C++ class instance.

Common classMX100 functions

MX100 class

DARWIN class

Visual C, Visual BasicVisual Basic.NET*, C#*

Visual C++

DARWIN functions

* Visual Basic.NET and C# correspond by Extension API.

Features• Control is achieved by retrieving the handle (device descriptor) that represents the

connection with the controlled unit. This means that, programs can be created

independently of the hardware environment of the MX100 or DARWIN.

• The API provides structures for collection of data corresponding to the function.

For example, the MX100 module information structure contains the module type,

the number of channels, the scan interval, and other information related to the

module. The same structure can be used even when the same data is retrieved

using different commands and different formats.

• This API is subordinate to the extension API. Call the API to activate. The

extension API holds the current status data internally. The extension API can

describe a program without using a structure.

Retrieval of Setup Data and ConfigurationProgram Example 2

This program executes the following three items. This program contains all three

items, but each item can be written and executed separately.

• Collective retrieval of setup data

• Collective setting of setup data

• Setting a DC voltage range for the channels

//////////////////////////////////////////////////////////////// MX100 sample for configuration#include #include "DAQMX.h"//////////////////////////////////////////////////////////////int main(int argc, char* argv[]){ int rc; //return code CDAQMX daqMX; //class CDAQMXConfig configdata; //connect rc = daqMX.open("192.168.1.12"); //get rc = daqMX.getConfig(configdata); //set rc = daqMX.setConfig(configdata); //range rc = daqMX.getConfig(configdata); configdata.setVOLT(1, DAQMX_RANGE_VOLT_20MV); rc = daqMX.setConfig(configdata); //disconnect rc = daqMX.close(); return rc;}//////////////////////////////////////////////////////////////

DescriptionCollective Retrieval of Setup DatagetConfig(configdata)

The setup data below can be retrieved by the collective retrieval of setup data.

• System configuration data: See the CDAQMXSysInfo class

(section 2.5).

• Status: See the CDAQMXStatus class (section 2.5).

• Basic settings: See the CDAQMXConfig class (section 2.5).


2-14 IM MX190-01E

NoteThe setup data can also be retrieved using the talkConfig member function and thegetChConfig member function. The talkConfig function is used to declare the retrievalof the setup data and retrieve the system configuration data, status, and networkinformation data. Then, the getChConfig function is used to retrieve channel setupdata in units of channels.

Collective Setting of Setup DatasetConfig(configdata)

The data below can be set by the collective setting of setup data.

• System configuration data: See CDAQMXSysInfo class (section 2.5).

• Basic settings: See the CDAQMXConfig class (section 2.5).

Setting a DC Voltage Range for the ChannelssetVOLT(1, DAQMX_RANGE_VOLT_20MV)

Sets channel number 1 to DC voltage range 20 mV. Scaling is not used.

First, the setup data is retrieved collectively. Next, the change described above is

made. Then, the data is set on the MX100 collectively. Use similar steps when

making changes to the settings.

Get the setup data collectively

Change the setup data CDAQMXConfig::setVOLT, etc.

(see "Setup Change" on page 2-6.)

CDAQMX::setConfig

CDAQMX::getConfig

Set the data collectively

Error Processing• Most member functions return the result of the function process using an error

number (0 if successful).

• The member function CDAQMX::getErrorMessage can be used to get the error

message string corresponding to the error number. The member function

CDAQMX::getMaxLenErrorMessage can be used to get the maximum length of

the error message string.

• The member function CDAQMX::getLastError can be used to get the errors from

the MX100.
