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
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.
