3 SOFTWARE
3.1 LIBRARIES
The RS-USBX interface can be used in conjunction with any application program (Excel, LabView etc.) or
programming language (VisualBasic, C++, Delphi etc.) that supports standard OLE interfacing.
The
DeviceCommLibs.pdf
(included with the documentation) contains detailed informations about the
structure and the usage of the Axel communication libraries.
The most relevant characteristics of the communication libraries are:
–
layered software structure;
–
low level data exchange layer;
–
data protocols layer (including Modbus RTU);
–
communication channel sharing with locking features for simultaneous application execution.
3.2 PC TOOLS
The setup program installs two sample programs for using the RS-USBX interface. Both programs are
furnished with the complete source code in Microsoft VisualBasic 6.0.
The main purpose of these programs are:
–
to supply the customer with very basic tools to work with RS-USBX on RS485, RS422 or TTL serial
lines;
–
to show, with very simple code, how to use RS-USBX and the relative support libraries with
application programs.
3.2.1
RS-USBXTool
RS-USBXTool allows to send and receive data bytes over the serial line. This tool uses the low-level
communication layer of the software libraries.
To use RS-USBXTool follow the instructions below:
