Description: DUT系列数据采集模块将温度传感器（热电阻，热电偶等）的输出信号或电流、电压直接转换成数字量，通过RS-485总线及标准通信协议将数据传送给主机。在模块上由89C51单片机管理模块自动工作，通道转换、ADC启动、采集数据、参比端补偿（热电偶）、引线电阻补偿（热电阻）、数字校零、非线性校正和数据处理等，均由单片机完成，主机仅在需要数据时，发送读取数据命令，模块给出已经线性化了的温度的数字量。通讯协议兼容台湾研华ADAM4000系列和松下PLC的通讯协议，可以与大多数组态软件直接连接，不需要额外的驱动程序，技术人员不需要有温度检测专门知识和编程能力即可使用。本产品主要用于各种现场的数据采集和控制系统。-DUT Series data acquisition module temperature sensor (RTD, thermocouples) De Shuchuxinhao or the current, voltage directly into Shuzi amount, via RS-485 bus, and data transfer standard communication agreement Ji Zhu Ji. 89C51 microcontroller in the module by the management module automatically, channel conversion, ADC start, collecting data, reference junction compensation (TC), lead resistance compensation (thermal resistance), digital calibration, linear calibration and data processing by the MCU to complete, the host only needs the data to send read data command, the module has been given a linear temperature of the digital. Communication protocol compatible with Advantech ADAM4000 series and the Panasonic PLC s communication protocol, can be directly connected with most of the configuration software, no additional drivers, technicians do not have temperature sensing capabilities and programming expertise to use. This product is mainly used for a variety of field data acquisition a Platform: |

Description: 单片机（stc89c52）通过RS485与PLC通信，采用modbus协议，利用单片机闲置的一个管脚置高或低，来判断出现单片机程序执行的情况。硬件连接比较简单，单片机通过485的A/B端连接到RS485/RS422，RS422连接但PLC。这个就是.c程序不是工程文件，下载后自己建立个keilC工程就可以了。-SCM (stc89c52) via RS485 communication with the PLC, using modbus protocol, using SCM idle a pin high or low, to determine the circumstances microcontroller program execution occurs. Relatively simple hardware connection, the microcontroller 485 A/B terminal is connected to the RS485/RS422 through, RS422 connection but PLC. This is not a project file .c program he established a keilC project after downloading it. Platform: |
