The MXIO Linux Library is a set of tools for programmers to use with Moxa’s ioLogik 4000, E2000,
and R2000 remote I/O. Programmers can use the library when developing applications to manage
I/O devices and obtain I/O data remotely over an Ethernet or RS-485 network. The MXIO Linux
Library is designed for x86 platforms and Moxa’s UC-7100-LX, UC-7400-LX, and IA-240-LX line
of embedded computers.
Supported Platforms
z arm-elf-mxio-library-x.x.x.x.sh – for UC-7100-LX line
z mxsacleb-mxio-library-x.x.x.x.sh – for UC-7400-LX line
z mxio-library-x.x.x.x.sh – for x86
z arm-linux-mxio-library-x.x.x.x.sh - for IA-240-LX line
Supported I/O Modules
For a list of I/O modules that are supported by this library, please refer to Chapter 10, Product

Chapter 2. Programming Flow
The process used to obtain access to a remote I/O device on an ioLogik is similar for both Ethernet
and serial interfaces. Five different scenarios are described below.
The following topics are covered:
Connecting to a Single Ethernet I/O
Connecting to Multiple Ethernet I/O
Connecting to a Single Serial I/O
Connecting to Multiple RS-485 I/O
Connecting to the ioLogik E2000 and Attached RS-485 I/O

ioLogik MXIO DLL API Reference Programming Flow
2-2
Connecting to a Single Ethernet I/O
The MXIO Linux Library establishes a data tunnel using Modbus commands to communicate with
the Ethernet I/O. Access is usually established using TCP port number 502.
ioLogik 4000 remote I/O
IP: 192.168.8.1
Port: 502
ioLogik E2000 Ethernet I/O
IP: 192.168.8.1
Port: 502
Three steps are required to access remote I/O data using the MXIO Linux Library.
1. Use MXEIO_Connect to connect to the Ethernet I/O using IP:Port (e.g., 192.168.8.1:502).
MXEIO_Connect should return a handle.
2. Use the handle to access the desired I/O point with Modbus commands or direct I/O
commands.
3. To finish the operation, use MXEIO_Disconnect to release Windows system resources.

Connecting to Multiple Ethernet I/O
Before multiple Ethernet I/O can be accessed over the network, make sure that each I/O has a
unique IP address.
ioLogik 4000 remote I/O
IP: 192.168.8.1
Port: 502
ioLogik E2000 Ethernet I/O
IP: 192.168.8.2
Port: 502
Each Ethernet I/O needs a unique handle in order to be accessed. Use MXEIO_Connect to obtain
the handle for each Ethernet I/O.

Connecting to a Single Serial I/O
ioLogik 4000 and R2000 I/O can be used in RS-485, RS-232 control networks. For access to I/O
over RS-485 or RS-232, please pay attention to the following:
z Your computer must be equipped with an RS-232 or RS-485 communication port.
z Make sure that the baudrate and communication parameters for the computer and the I/O are
identical.
z Make sure that the I/O is running under Modbus/RTU
ioLogik 4000 remote I/O
ID: 10
ioLogik E2000 Ethernet I/O
ID: 10
Four steps are required to access remote I/O data using the MXIO Linux Library.:
1. Use MXSIO_OpenCommport to open the COM port and connect to the serial I/O.
2. Use MXSIO_Connect to connect to the serial I/O using the Unit ID (e.g., 10).
MXSIO_Connect should return a handle.
3. Use the handle to access the desired I/O point with Modbus command sets or direct I/O
command sets.
4. To finish the operation, use MXSIO_Disconnect and MXSIO_CloseCommport to release
Windows system resources.

Connecting to Multiple RS-485 I/O
In most real world applications, multiple RS-485 I/O are often connected to the same network.
One RS-485 network can support up to 32 nodes.
ioLogik 4000 remote I/O
ID: 01
ioLogik E2000 Ethernet I/O
ID: 32
Each serial I/O requires a unique handle. Make sure each serial I/O server already has its own
handle before accessing the I/O points.
