1794-IM81794-IM81794-IM8PLC采用循环扫描的工作方式，在PLC中用户程序按先后顺序存放，CPU从***条指令开始执行程序，直到遇到结束符后又返回***条，如此周而复始不断循环。PLC的扫描过程分为内部处理、通信操作、程序输入处理、程序执行、程序输出几个阶段。全过程扫描一次所需的时间称为扫描周期。当PLC处于停状态时，只进行内部处理和通信操作服务等内容。在PLC处于运行状态时，从内部处理、通信操作、程序输入、程序执行、程序输出，一直循环扫描工作。1．输入处理输入处理也叫输入采样。在此阶段，顺序读入所有输入端子的通端状态，并将读入的信息存入内存中所对应的映象寄存器。在此输入映象寄存器被刷新。接着进入程序执行阶段。在程序执行时，输入映象寄存器与外界隔离，即使输入信号发生变化，其映象寄存器的内容也不会发生变化，只有在下一个扫描周期的输入处理阶段才能被读入信息。备货，备货，降降降，火火火，火火火……————————————————————————————————公司名称：厦门泰尼电气有限公司联系人：小黄（销售代表）联系电话：0592-6809319传真号码：0592-6890859（麻烦备注01006收）手机：18950191386***号码:2917675397邮箱：2917675397@***.com诚信经营，质量为首，诚信至上，泰尼电气小黄竭诚为您服务！！！————————————————————————————————REXROTHSTARLINEARBEARINGS1622-213-214-10WRAILREXROTHINDRAMATDSS02.1SERCOSINTERFACEREFURBISHEDREXROTH1070076509SF-A2.0041.030-​10.050REXROTH1070076709SF-A4.0125.030-​14.050REXROTHPROPAMPLIFIERVT5002-25/R5ENEWINBOXManne***annRexroth4WE10G31/CG24NHydraulicValveREXROTHHYDRAULICVALVE5-3WE10A32DIRECTIONAL96VManne***annRexroth4WEG61/EW110N9D​ALREXROTHVT5003S40R1PROP.AMPLIFIERGOODTAKEOUTNEWREXROTHVT-VRPA1-50-1XREXROTHVT-3014NSPPVT3014REXROTHVT-2000K42USPPVT2000K42REXROTHPROPORTIONALDIRECTIONALVALVENEW-ClarkLiftTruckPumpP/N2743553byRexrothREXROTHPRECISIONROLLEDTHREADBALLSCREW3465770-0000REXROTH8-981-553-454USPP8981553454RexrothValve4WE10***0/CW110N​9DA.MNRR978908696.NewManne***annRexroth4WE10C32/CG24N9Z4ValveRefRexrothPRotairpnuematicdirectionalvalveR431006581RexrothVT5011S42R1ProportionalAmplifier#26623REXROTHR900938012NSPPR900938012REXROTHPERMANENTMAGNETMOTORSF-A2.0020.030-​10.050RexrothPropAmplifierVT3024534REXROTHPropAmplifierVT3006S35R5#2965REXROTH0-38398-108NSPP038398108REXROTH3-842-503-783NSPP3842503783REXROTHP6810-3180USPPP68103180REXROTHP-68180-3180USPPP681803180REXROTHR900961763USPPR900961763REXROTHVT2000S41NSPPVT2000S41REXROTHLINEARBEARINGCARTRIDGES,P/N:R166179410REXROTHLINEARBEARINGCARTRIDGES,P/N:R182433110REXROTH8-981-553-451USPP8981553451REXROTHVT2010S42USPPVT2010S42REXROTH4WE10J33/CG24N9​K4USPP4WE10J33CG24N9K​4RexrothR185131310RunnerBlock/RollerRallNEWREXROTHM-3-SED-6-UK13/​350-C-G24-N9K4USPPM3SED6UK1335REXROTH041261-516USPP041261516Rexroth4WE10***0/CW11ON​9DAR900561288HydraulicValveREXROTHM-3-SED-6-CK13/​350-C-G24-N9K4USPPM3SED6CK1335BOSCHREXROTH3842174350SENSORHEADNEWNEWREXROTHR900928826LOGICCARTRIDGELC63A20E7XREXROTHDPR-10DigitalAmplifierREXROTHDPR-10DigitalAmplifierREXROTHPNEUMATICCYLINDER18"STROKETM-841000-3180RexrothVT3000SevoCardCat#VT3000S34R5UsedRexrothServoAmplifierVT5011S45R1#24334REXROTHHYDRAULICVALVE4WE6D60/OFEG24N​9K4RR00009279RexrothHydrauliccylinder50mmx120mmREXROTHANALOGAMPLIFERVT3018MANNE***ANNREXROTH4WE10E40/CG24N9​DJLUSPP4WE10E40CG24RexrothVT3000-36VT3000AmplifierCardNEWRexrothHeatExchangerEKS-524-0EKS5240RexrothVT5011ProportionalAmplifierCardVT5011RexrothDR6DP1-53/50YpressurereducingvalveboschNEWREXROTHUS00880459EXTENDERCARDEXT100-32C-1XBOSCHREXROTHHYDRAULICPUMPS30S24HJ15LR978037281Rexroth4WE-6-J60EW110N9K4directionalspoolvalveNEW)
