Modbus Client Software Library

Need to talk Modbus for your SCADA or controller application? AB Tech Solution's Modbus Client Software Library can be used to implement a Modbus client using either the Modbus/TCP or Modbus/RTU serial protocol.

Depending on whether you are implementing Modbus serial or TCP, the client library will allow you to read coils & discrete inputs, write coils & discrete outputs, read input registers, and read/write holding registers. The following commands are available:

Read Coils
Read Discrete Inputs
Read Holding Registers
Read Input Registers
Write Single Coil
Write Single Register
Read Exception Status
Write Multiple Registers
Report Slave ID
Read File
Write File
Mask Write Register
Read/Write Multiple Registers

The library includes all source code, and header files, as well as an implementer's guide to the library to help you implement the code on your specific hardware.

For developers who want to add fieldbus protocol capability to their products themselves, AB Tech Solution offers several fieldbus software libraries to save you money,time & effort.

All of the libraries are written in ANSI C, and can be ported to any microcontroller of microprocessor platform.
