Reference
A function consists of multiple, simpler functions. The Reference section lists the
functions that make up a given function. This information can be used to understand
the action of the function and/or troubleshoot errors.
Functions for Visual C and Visual Basic are executed by calling the Visual C++ class
instance. Therefore, the Reference section lists the class name and the member
function name and/or the function name.
The names are listed in alphabetical order.
Program Description
Sample programs are printed in this manual in monospaced font. Note the following.

Chapter 1 Before Using the API
1.1 Introduction to Functions
Supported Models
This 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 Languages
Languages 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 MX100
Communication Functions
1
Before Using the API
Functions used to communicate with the MX100 via the Ethernet interface.
Setup Functions
For 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.
IM MX190-01E
1-1
1.1 Introduction to Functions
• 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
Utilities
Provides functions for converting measured values into character strings, retrieving
error message strings, and other utility functions.
Functions for DARWIN
The 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 Functions
Functions used to communicate with DARWIN via the Ethernet interface.
• Setup Functions
Sets 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.
1-2 IM MX190-01E
1.1 Introduction to Functions
• Retrieval of setup data
Retrieves 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
• Utilities
Provides 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 Function
1
Before Using the API
Functions 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.

connection with the controlled unit. This means that, programs can be created
independently of the hardware environment of the MX100 or DARWIN.
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.
extension API holds the current status data internally. The extension API can
describe a program without using a structure.
