 石油化工生产中plc常常用于大机组的联锁与操控。对于机组的振荡、位移等参数，点数较少时，能够选用变送器、传感器变换成4-20ma信号送入plc，完成联锁操控，但对键相、差胀等特别丈量参数或振荡、位移等丈量参数点数较多时，信号变换的难度大、成本高，运用传统的框架式机械维护体系反而会经济、有用。美国bently公司3500体系是传统的框架式机械维护体系之一，它能够运行于各种冗余等级，包括双电源供电和更高请求下的三重模块冗余(tmr)监测器组态。每个i/o卡能够对 4-6个点的信号进行变换处理，并经过编程的办法完成联锁逻辑。茂名乙烯厂在2006年7月建成投产的2＃丁二烯设备的压缩机联锁、操控中，选用德国西门子公司的s7-400h体系完成总的联锁和进程操控，外壳振荡、轴瓦温度的联锁主要在bently3500中完成。为了完成数据同享和联锁冗余，需要将bently3500中的模拟信号和报警、联锁信号以通讯方法传输到s7-400h。本文以2＃丁二烯压缩机操控体系为例，描绘了simatic s7-400h与bently 3500之间modbus rtu协议通讯完成的进程。
