Easy Addressing Using Slot Number + Channel Number
Intuitive and Easy-to-Use Function Calls
For small-scale data acquisition systems, you may consider developing
your own application in-house, rather than using an expensive
SCADA package. MOXA provides a powerful MXIO library for different
programming languages, including Visual Basic, Visual C++, and
Borland C++ Builder, so you can build your application quickly. You can
retrieve data in your application by using MXIO commands designed
for the traditional Modbus protocol. Direct I/O command sets are also
available for slot and channel-based commands. The MXIO library
supports different platforms, including Windows 2000, Windows XP,
Windows 2003, Windows CE 5.0 x 1 and Embedded Linux x 2.
1. Windows CE 5.0 ARMV4I support has
been verified for MOXA’s UC-7408 and
UC-7420.
2. Embedded Linux is only supported for
MOXA’s UC-7100 line.

MXIO DLL Library
The MXIO library is straightforward and easy to understand. Take a look at the following illustration to see just how easy it is. (MXIO library 1.0.0.1 only)
Traditionally, programmers had to include a calculation for the Modbus
address in their program. Now they only need to point out which slot
and channel they want to access. Working in this way is easier and
more intuitive.
