一体化机柜智能设备协议tec空调通信协议

1、半导体空调器通信协议概述 Summarization该控制系统支持MODBUS 通信协议，该协议定义了一个与基础通信层无关的简单协议数据单元(PDU)，协议的具体约定，请查询MODBUS.的网页().The communication supports MODBUS protocol, the MODBUS protocol defines a simple protocol dataunit(PDU) independent of the underlying communication layers. Please reforthe detail.to find所支持消息帧传输模式：RTU

2、模式， 8位数据位，无校验位，1位停止位，CRC校验，波特率9600bps.信息应答等待最长时间50ms.The data frame mode is: RTU mode, data bits is 8, none parity, sotp bit is 1, CRC check, baudrate is 9600bps. The max. waiting time of respondence is 50ms.有效功能代码 Valid Function Code该控制系统支持以下功能代码:This system support function code as following:功能代码F

5、ction code is used to read from 1 to approx. 125 contiguous input registers in a remote device.有效错误代码 Valid Error Code该控制系统支持如下错误代码:This system support error code as following:数据类型 Daype该数据特征有两种形式，任意的单一位类型和16位的数据类型。单一位类型包含只读型DiscreteInput型数据和可读-写的Coil型数据。16位的数据类型包含只读型InputRegister数据。Register数据和可读-写的

6、HoldingThe data has two types: bit data and word data. The bit data include discrete input dahat isread-only and coil dahat is readable and writable. The word data include input registert isread-only and holding registert is readable and writable.错误代码Error Code定义Definition描述Description01 (0 x01)不合能指

The data is invalid.04 (0 x04)从机故障Slave fail从机执行主机请求的动作时出现错误.The slave fail while executing the request.12 (0 x0

8、C)CRC 校验错误CRC check errorCRC校验错误 CRC check error05 (0 x05)写单个线圈Write Single Coil在一个设备中，使用该功能码写单个输出为 ON或者OFF. This function code is used to write a single output to either ON or OFF in a remote device.06 (0 x06)写单个寄存器Write Single Register在一个设备中，使用该功能码写单个保持寄存. This function code is used to write a sin

9、gle holding register in a remote device.16 (0 x10)写多个寄存器Write Multiple Registers在一个设备中，使用该功能码写连续寄存器块. This function code is used to write a block of contiguous registers in a remote device.数据索引 Data Index该控制系统所有的数据地址遵循MODBUS数据格式，即数据的地址是从零开始编址的，第一个数据的地址为零。支持全部0-65535地址的代码.，但未定议的地址数据，将返回不确认的数据或错误信息Dat

10、a address of the controller register follows MODBUS communication protocol, which startfrom 0 and theum address is 65535. But any address is not definedhe controller, if themaster request data at undefined address, the controller will return error. The corresponding data as follows:MODBUS Coil Data
