本文介绍浙江中控技术股份有限公司JX-300XP系统的升级版系列产品的MODBUS现场总线功能，在某煤基化工脱盐水站控制系统中的应用与试验研究。本工程采用以XP248多串口多协议通讯卡为核心模块的现场总线通讯方式，在电动机控制方面取代了传统的DCS点对点信号传输方式，将脱盐水站内所有电动机（包括变频电机）均纳入MODBUS现场总线通讯方式控制，节省了大量电缆材料与施工周期和成本。通过实际调试运行的通讯时间对比充分说明浙大中控的JX-300XP系统能够完成MODBUS现场总线通讯功能，而且能够保证可靠性和实时性的要求，但是在应用设计配置时必须注意：其每个通道所带电机设备的数量对通讯速度的影响是巨大的，特别是对于变频器模拟量输出信号传输速度的影响将呈几倍甚至几十倍的增加。当数据传输通讯时间长达10~40秒时，则整个系统无法满足工业生产正常运行的要求。

MODBUS fieldbus function upgrade edition series products introduced in Zhejiang control ed technology Limited by Share Ltd of JX-300XP system, application and test study on a domestic coal based chemical desalted water station in control system. The field bus communication mode with XP248 multi serial port multi protocol communication card is the core module used in this project, in the motor control to replace the traditional DCS point to point signal transmission mode, the desalted water station al motor (including the frequency conversion motor) were included in the control of the MODBUS field bus communication mode, save a lot of cable material and construction period and the cost of. Through actual debugging communication time comparison operation to JX-300XP system of SUPCON is able to complete the MODBUS field bus communication function, but also can ensure the reliability and real-time requirements, but in the design of the application configuration must: the influence of the number of motor equipment with each channel on the communication speed is enormous, especial y for effect of increasing converter analog output signal transmission speed wil be several times or even several times. When the data transmission communication time for 10~40 seconds, then the whole system cannot meet the requirements of industrial production of the normal operation of.
