1771-HSARS控制器1771-HSARS控制器1771-HSARS控制器抽像一点讲，过程控制渗透在生活的各个角落。特别是在数控行业，尤为明显。早期在PLC时代，几乎是一统天下。当大小不一的控制卡公司如雨后春笋般成长起来时，控制卡在过程控制逐步体现出强劲优势。其编程手段往往邦定非常成熟的编程工具，如：CB,VC,Dephi,CB。故其推广非常迅速.很快拥有大量客户群。但是，作为编程者，碰到同一程序需要控制多个同样设备时（动作不一定同步），往往在Window多任务系统的影响下，很快想到多线程技术，其实多线程编程对系统依赖性较强，不同级别的处理，将导致程序的维护成本增加，并且还需要考虑线程之间的通讯，使编程起来较为麻烦。事实上，依靠过程编程的思想，会使程序获得更简单的做法。纯粹从编程角度来看，过程控制编程应包含几个要素，下面以C++伪码方式来表示一个类，较易说明问题：注意：有很多程序员在不同编译器下，需要不同的OnRunAction函数版本，以上实现***为简单，但有一些较特殊。比如：在程序启动时，就驱动所有设备，这点本人在VC6.0环境有过经验，可以分享一下，其它环境下，还需同胞们一起去努力发现。还有一点声明，多线程技术也不是一无是处，在花费时间较频繁的通讯编程方面，它的优势，还是有相当的力。ASEABROWNBOVERIYT204001FK/1USPPYT204001FK1ALLENBRADLEY1336-C010-EADUSPP1336C010EADSIEB&MEYER***026381CNSPP***026381CUSEDPerceptron390-0049Enna17Monitor0520776002ASEABROWNBOVERIACH501-050-4-0​0P2USPPACH501050400P2ALLENBRADLEY2711P-RDK10CUSPP2711PRDK10CASEABROWNBOVERIIOP-05USPPIOP05PanasonicACServoMotorMHMA102P1CFreeShipTEXASINSTRUMENTSSERIES500PLC,520C-1102TEXASINSTRUMENTSPLC500-5039NSPP5005039ASEABROWNBOVERI3GAA092001-CSANSPP3GAA092001CSAPanasonicMDD153A1WACServoDrivePanasonicMFA020LE2NSCACServoMotorwith60daywarrantyTEXASINSTRUMENTSPLC3RW2-E045NSFP3RW2E045CONTROLTECHNIQUESVCB-4025-NAUSPPVCB4025NATEXASINSTRUMENTSPLC2497302USPP2497302ASEABROWNBOVERIOETL-NF600A-2S​WNSFPOETLNF600A2SWTISiemens500-5114-ARemoteBaseControllerwRS485PortPLC500-5114A5005114ASIEMENSTEXASINSTRUMENTS505-6204ANALOGMODULEXLNTFASTSHIPPINGPanasonicACServoDriverMADHT1507ENIBFreeShipRELIANCEELECTRIC31C301USPP31C301EnlargeXYCOM3300ACTUSPP3300ACTASEABROWNBOVERI5730030-DRUSPP5730030DRTEXASINSTRUMENTSPLCPFS-3605-AUSPPPFS3605AINDRAMATKDS1.1-100-300​-W1USPPKDS11100300W1PANASONICACSERVODRIVERMDD203A1W200V50/60HZ2.0KW2500P/RHASEASEABROWNBOVERIDCS401-0610USPPDCS4010610TEXASINSTRUMENTSPLCPWB-2461414-00​01USPPPWB24614140001TEXASINSTRUMENTSPLC5TI-1021-1USPP5TI10211FISCHER&PORTER686B608U01NSPP686B608U01ASEABROWNBOVERI57310001-KD/5USPP57310001KD5MODICONAS-B984-101USPPASB984101PERCEPTRON495-0102-01USPP495010201ALLENBRADLEY284D-FVD2P3Z-1​0-CR-3NSPP284DFVD2P3Z10C​R3HONEYWELLTC-O061USPPTCO061ALLENBRADLEY809-A12ENSPP809A12ETEXASINSTRUMENTSPLC555-1103USPP5551103texasinstrumentscardmoduleplc500-503550050352462150-00124621500001545-1101TexasInstrumentsSimaticPLCTI545TI5451101N300GENERALELECTRICDS3800HIOA1B1BUSPPDS3800HIOA1B1BPanasonicMDDDT5540001ACServoTexasInstruments5TI-1032-2TEXASINSTRUMENTSPLC2594424-0002-U​LUSPP25944240002ULASEABROWNBOVERI006539960-KUSPP006539960KTEXASINSTRUMENTSPLC2490005-0001USPP24900050001TEXASINSTRUMENTSPLC505-4716NSFP5054716FOXBOROP0970EJ-DNBXNSPPP0970EJDNBXTEXASINSTRUMENTSPLC505-4932USPP5054932PACIFICSCIENTIFICS31GNAA-RNNM-0​0USPPS31GNAARNNM00ASEABROWNBOVERIEH300C-1LUSPPEH300C1LTEXASINSTRUMENTSPLC164-2111NSFP1642111TexasInstruments5TI-1029-1RELIANCEELECTRIC418287-3AUSPP4182873AALLENBRADLEY1785-L11BNSFP1785L11BTEXASINSTRUMENTSPLC315-DDUSPP315DDTexasInstrumentsSequencerType#571SEQUENCER!(AG01)PANASONICM***011A1EECP-16A-11-J213​A-SPM***011AT7SERVOMOTORWORKINGPanasonicACServoMotorM***Z042B1EFreeShipTEXASINSTRUMENTSPLC505-4316NSPP5054316FOXBORO202S-07-SSSFSS​ESNFUSPP202S07SSSFSSES​NFTexasInstrumentsPM550-400#TEXASINSTRUMENTS505)
