工业上的MODBUS通讯协议已经成为电子控制器上的一种通用语言协议。通过此协议，控制器相互之间、控制器经由网络（例如以太网）和其它设备之间可以通讯。它已经成为一通用工业标准。用它来实现不同厂商生产的控制设备连成工业网络，进行集中监控。 基于此，可以根据实际工业网络数据采集的一主多从的实际数据选择模型，该模块采用了此协议，因为协议定义了一个控制器能认识使用的消息结构，而不管它们是经过何种网络进行通讯的。因此不管上位机是什么样类型的测控设备，就按固定的MODBUS通讯协议要求的协议格式来回应来自主设备的请求，并进行侦测错误记录。按照协议中要求的消息域格局和内容的公共格式回应。 在MODBUS通讯网络上，此协议要求通讯时必须知道每个通讯模块的设备地址，每个通讯模块识别按地址发来的消息，根据功能码来决定要产生何种动作。如果需要回应，控制器将生成相应的反馈信息并用MODBUS协议发出。 通讯模块在用MSP430F149单片机控制通讯时采用了MODBUS协议支持的两种数据传输模式：ASCII模式及RTU模式。ASCII模式中字符串每个8位字节分2个ASCII码发送。RTU模式字符格式中每8位字符分2个4位16进制格式数据传送。
