1746-C161746-C161746-C16（2）程序执行阶段。在执行用户程序过程中，PLC按照梯形图程序扫描原则，一般来说，PLC按从左至右、从上到下的步骤逐个执行程序。但遇到程序跳转指令，则根据跳转条件是否满足来决定程序跳转地址。程序执行过程中，当指令中涉及输入、输出状态时，PLC就从输入映像寄存器中“读入”对应输入端子状态，从输出映像寄存器“读入”对应元件（“软继电器”）的当前状态。然后进行相应的运算，运算结果再存入输出映像寄存器中。对输出映像寄存器来说，每一个元件（“软继电器”）的状态会随着程序执行过程而变化。（3）输出刷新阶段。程序执行阶段的运算结果被存入输出映像区，而不送到输出端口上。在输出刷新阶段，PLC将输出映像区中的输出变量送入输出锁存器，然后由锁存器通过输出模块产生本周期的控制输出。如果内部输出继电器的状态为“1”，则输出继电器触点闭合，经过输出端子驱动外部负载。全部输出设备的状态要保持一个扫描周期。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！！！————————————————————————————————Siemens6ES5100-8MA02,6ES51008MA02nSiemens6ES5135-3KA13,6ES51353KA13Siemens6ES5135-3UA11,6ES51353UA11Siemens6ES5183-3UA12,6ES51833UA12Siemens6ES5183-3UA13,6ES51833UA13Siemens6ES5185-3UA00,6ES51853UA00Siemens6ES5393-0UA14,6ES53930UA14Siemens6ES5393-0UA15,6ES53930UA15Siemens6ES5434-7LA12,6ES54347LA12nSiemens6ES5458-7LB11,6ES54587LB11nSiemens6ES5525-3UA21,6ES55253UA21Siemens6ES5544-3UA11,6ES55443UA11Siemens6ES5900-7AD11,6ES59007AD11Siemens6ES5942-7UB11,6ES59427UB11Siemens6ES7331-7PF01-0AB0,6ES73317PF010AB0,FasSiemens6ES7331-7PF11-0AB0,6ES73317PF110AB0,FasSiemens6ES7352-1AH02-0AE0,6ES73521AH020AE0,FasSiemens6GK7343-5FA00-0XE0,6GK73435FA000XE0,FaSiemens6GK7443-5DX02-0XE0,6GK74435DX020XE0,FaMitsubishiA1NCPU,A1NCPUMitsubishiA1S-D75-P1-S3,A1SD75P1S3MitsubishiA2CPU,A2CPUMitsubishiMitsubishiAX21EU,AX21EUMitsubishiAX21,AX21MitsubishiMitsubishiAX71,AX71MitsubishiMitsubishiAY60E,AY60EMitsubishiOmronC500-OC223,C500OC223Omron***2A-40CDR-A,***2A40CDRAOmron***2A-40CDR-D,***2A40CDRDOmron***2A-40CDT1-D,***2A40CDT1DMitsubishiFX1N-60MT-DSS,FX1N60MTDSSMitsubishiFX1N-60MT-ESS,FX1N60MTESSMitsubishiFX-32MT-ESS/UL,FX32MTESSULTelemecaniqueTSXDST1635,TSXDST1635TelemecaniqueTSXRPM3216,TSXRPM3216AlfaL***alSDA492-620-901,492620901Omron***0K-CDR-A,***0KCDRAHitachiEC2-40HRP,EC240HRPMitsubishiFX1N-60MR-DS,FX1N60M***nTelemecaniqueTBXLEP020,TBXLEP020Siemens6SE3210-7BA40,6SE32107BA40AlfaL***alSDA492-620-902,492620902MitsubishiFX2N-48MT-DSS,FX2N48MTDSSMitsubishiAX82,AX82MitsubishiMitsubishiFR-A024-S2.2K-EC,FRA024S22KEC,FastSMitsubishiFR-A540-0.75K-EC,FRA540075KEC,FastShMitsubishiFR-A740-00126-EC,FRA74000126EC,FastSiemens6ES7357-4AH03-3AE0,6ES73574AH033AE0,FaMitsubishiFX2N-48MR-DS,FX2N48M***nABBACS601-0006-3,ACS60100063Danfoss175H1016VLT3004,175H1016Siemens6***6640-0CA11-0AX1TP177MICRO,6***66400Siemens6***6641-0BA11-0AX0OP77A,6***66410BA110A...Siemens6ES5525-3UA11,6ES55253UA11MitsubishiFX2N-48ET-DSS,FX2N48ETDSSOmronC200HW-NC213,C200HWNC213OmronR88D-KN02H-ML2,R88DKN02HML2Siemens6ES5430-6AA11,6ES54306AA11Omron***0H-C5DR-DE,***0HC5DRDEAllenBradley22B-D010N104,22BD010N104Siemens6ES7952-1AL00-0AA0,6ES79521AL000AA0,FasSiemens6ES7407-0KA02-0AA0,6ES74070KA020AA0,FasBeijerMTA100,MTA100TelemecaniqueTSXAEZ414,TSXAEZ414BeijerK30Exter,K30EXTERBeijerMA***0+,FastShippingSiemens6ES7133-0BN11-0XB0,6ES71330BN110XB0,FaMitsubishiFX0N-60MR-ES/UL,FX0N60MRESUL,FastShMitsubishiFX2N-48ER-ES/UL,FX2N48ERESUL,FastShiSiemens6ES5380-7AA11,6ES53807AA11nSiemens6ES5410-7AA11,6ES54107AA11n)
