串口调试程序，包含modbus通讯协议，可实现地址显示及数据修改-Serial debugger, including Modbus communications protocol, can achieve the address display and data modifications

NImodbus库 我也是在网上下的，希望对他人有帮助，不好，请见谅！-NImodbus library

用LabVIEW编写的基于modbus通信协议的串口通信程序-modbus CRC16算法-Written using LabVIEW serial communication protocol based on the modbus communication program-modbus CRC16 algorithm

这个是MODBUS控制电磁阀的一个程序。其中还有AD采集的部分。对CRC校验用查表的方法。至于怎样把校验的结果拆分成高低位字节，再发送，看程序吧。 -This is a MODBUS control valve procedures. Which are part of AD collection. CRC check on use of look-up table method. As for how to verify the results split into high and lo

在IFIX组态软件中,采用VB编写GPRS通讯程序,与支持MODBUS协议的PLC进行数据通讯.-In IFIX configuration software, using VB, GPRS communication procedures, and support of MODBUS protocol PLC data communication.
