TwinCAT常见问题-如何声明定时器,使用定时器TON模块TC3

TON功能块功能：当输入为高电平时，计时器开始计时，CV表示计时器计时的当前值，而PV则是计时的目标值，当CV的值等于PV的值时，输出置1。在主程序接下去的地方按下F2并添加TON功能块。InputAssistantCategories: Items:Variables▲NameTypeOriginModuleCalls-{}Tc2_StandardLibr3fy山之5编j的M3.2,0.0(bedcho...InstanceCalls仔-…mBistableFunctionBl...FunctionBlocks:口--1曰CounterKeywordsjE_JTmerConvers1□n0perators旬TOFFUNCTION_BLOCKft之后生的曲也(bedcfto...11TONFUNCTION_BLOCK320.G(bedcho...1]TPFUNC7T0N_BL0CK初门为也3.2.0.Q(beMo...:口(£)TmerfLTIME);日」Trigger*{}Tc2_SystemLibr3fy无之司臼杷匹J.2.0.0(bedchoff...主{}Tc3_ModuleLibraey熄q(bedc/ioff...囹Insertwitharguments □InsertwithnamespaceprefixFT]Structuredview团ShowdocumentationDogjmentation:□KCancel□KOrigintcjstandard,3.2.0.Q(beckho...▲Origintcjstandard,3.2.0.Q(beckho...tea-“■■tea-“■■u++-TOFFUNCTFON_BLO€K超&3.2.0.Q(beckho...三1TONFUNCTTON_BL(XXtc2_standar^(beckho...TPFUNCTION-BLOCK卦壶向3.2.0.Q(beckho...+^TmerfLTtME)+—JTrigger+{}Tc2_SystemLibrarytc2_system^3.2.0.Q(beckhoff...+{}Tc3_ModuleLibrary比之m0血㈤(bedchoff...merAutoDeclare这里我取名为t1ral(SET:=ral_aet,RE1SET1:=ral_re3etrQI=>ral_output);cl：：CD:=cl_CDuntPLOAD:=cl_lDadrF7:=500rQ=>cl_outputfCV=>Cl_CUEEEnt);cl_CDunt:=NUTcl_CDunt;tl：IN:=tltimer,FT:=T#3Sr2=>tloutputrET=>tlcurrent);

F-TRIG功能块功能块功能：当输入产生一个下降沿，那么在接下来的一个周期内，输出将保持为1。在主程序接下去的地方按下F2并添加F-TRIG功能块。InputAssistantVariables▲NameTypeOriginModuleCalls-{}Tc2_StandardLibr^ytc2_stand3rdf(bedcho...InstanceCalls区…包BistableFunctionBl...FunctionBlocks：Q---CounterKeywords!EConversionOperators1]TOFFUNCH04LOCKtc2_stand3rdf3.2.0.Q(beMo...g]TONFUNCTION_BLOCK比N_筝拈门为也(beckha..旬TPFUNCTION_BLOCKtc2_stand3fd/(bedcho...!Q_^Tmer[LTIME)：GJTrigger田{}Tc2_5ystemLibr^ytc2_syst^(beckhuff…由{}Tc3_ModuleLibr^fytc3_modu!ef3.2,0.0(bedchoff...Categories:Items:[3Insertwitharguments国]StructuredviewFT]ShowdocumentationInsertwithnamespaceprefixDogjmentation:OKCancelOKOrigin3.2.0.Q(beckho...▲Origin3.2.0.Q(beckho...-{}Tc2_5tandardBistableFunctionBl...Countermer_JTrigger圄F_TRIGFUNCTTON_BLO€Ktc2_standardf(beckho...tc2_standardtc2_standardf(beckho...[f|R_TRIGFUNCTTON_BL(XX{}{}Tc2_System Librafytc2_system^(berfchoff...{}Tc3_ModuleLfbrafytc3_modu!e^3.2.0.Q(beckhoff...AliIoDeclaretrigl(CLK:=trigl_cllct^=>trijl_outputJ;这里我取名为TRIG1trijl_clk:=NDTrtrijl_clk; 一一此处，trig1_clk,trig1_output均为bool量。因为触发器的功能特殊，所以，在程序末端设立一个断点来看程序执行结果，在程序一口介以后，在程序最后有一个return，在此设立一个断点，方法如图：
