有的PLC厂家或第三方厂家还开发了使用PLC的组态软件，用以实现计算机对PLC控制系统监控，以及与PLC数据。PLC的用户也可基于DOS或WINDOWS平台开发用于PLC控制系统的应用软件，以提高PLC系统自动化及智能化水平。这方面的软件已日益受到重视。总之，为了用好PLC，PLC的支持软件越来越丰富，EFB1724VHG性能也越来越好，其界面也越来越友好，也因此，它的情况如何，已成为评判PLC性能的指标之一。5.7可靠控制为使PLC能可靠工作，在硬件与软件两个方面PLC厂家都采取了很多措施，对一些特殊可靠要求的PLC，还有相应的特殊的措施，如热备、冗余等等。这在介绍PLC的特点时已作了叙述。台达风扇代理销售询购产品，欢迎咨询！可靠措施的目的是增加PLC平均故障间隔时间、MTBF（MeanTimeBetweenFailure）及减少PLC的平均修复时间、MTTR（MeanTimeToRepair），以提高PLC的有效度A（***ailability）。A=MTBF/(MTBF+MTTR)式中A--有效率，MTBF--平均故障间隔时间，MTTR--平均修复时间，当然，A值越大越好，它可使PLC系统得到充分的利用，是为什么要使用PLC的重要指标。系统拓扑示意图，问题的提出，由于快速实时采集现场数据如果按GPRS流量收费的话，费用会很高，会给使用GPRS服务的客户带来较大的经济负担，但是不是每个客户都要实时监视现场仪表的参数、一些参数由于相对变化慢、几分钟采集一次就能满足需要，EFB1724VHG这样用户就可利用GPRS运营商所提供的包月服务，数据流量在50兆以下每月只收30元。BG0903-B042-0003615KL-04W-***4715KL-05W-B204715MS-12T-***1404KL-04W-B303108NL-05W-B10BG0903-B043-0004710KL-04W-B104715KL-05W-B305915PC-12T-B101404KL-04W-B403108NL-05W-B20BG0903-B044-0004710KL-04W-B204715KL-05W-B405915PC-12T-B201404KL-04W-***3108NL-05W-B30BG1002-B044-0004710KL-04W-B304715SL-05W-B205915PC-12T-B301604KL-04W-B303108NL-05W-B40BG1203-B042-0004710KL-04W-B404715SL-05W-B303610KL-05W-B401604KL-04W-B403108NL-05W-***BG1203-B043-0004710KL-04W-***4715SL-05W-B403610KL-05W-B401604KL-04W-***3110KL-05W-B102806GL-04W-B304712KL-04W-B104715SL-05W-***3610KL-05W-***1606KL-04W-B303110KL-05W-B202806GL-04W-B404712KL-04W-B204715SL-05W-B603610KL-05W-***1606KL-04W-B403110KL-05W-B302806GL-04W-***4712KL-04W-B305015KL-05W-B103610KL-05W-B601606KL-04W-***3110KL-05W-B402806KL-04W-B304712KL-04W-B405015KL-05W-B203610RL-05W-B101608KL-04W-B103110KL-05W-***3115PS-12T-B304715KL-04W-B105015KL-05W-B303610RL-05W-B201608KL-04W-B203110KL-05W-B603610PS-12T-B104715KL-04W-B205015KL-05W-B403610RL-05W-B301608KL-04W-B303110RL-05W-B103610PS-12T-B204715KL-04W-B305015KL-05W-***3610RL-05W-B401608KL-04W-B403110RL-05W-B203610PS-12T-B304715KL-04W-B405910PL-05W-B103610RL-05W-***1608KL-04W-***3110RL-05W-B304710PS-12T-B204715KL-04W-***5910PL-05W-B203610RL-05W-S101611KL-04W-B203110RL-05W-B404710PS-12T-B304715SL-04W-B205910PL-05W-B303610RL-05W-S201611KL-04W-B303110RL-05W-***4715MS-12T-B104715SL-04W-B305910PL-05W-B403610RL-05W-S301611KL-04W-B403110RL-05W-B604715MS-12T-B204715SL-04W-B405910PL-05W-***3610RL-05W-S401611KL-04W-***3110RL-05W-B704715MS-12T-B304715SL-04W-***5910PL-05W-B603610RL-05W-S502004KL-04W-B303110RL-05W-B804715MS-12T-B404715SL-04W-B605910PL-05W-B703612KL-05W-B302004KL-04W-B403110RL-05W-S104715MS-12T-***5015KL-04W-B105920PL-05W-B103612KL-05W-B402004KL-04W-***3110RL-05W-S205915PC-12T-B105015KL-04W-B205920PL-05W-B202406KL-04W-***2006ML-04W-B203110RL-05W-S305915PC-12T-B205015KL-04W-B305920PL-05W-B302408NL-04W-B102106KL-04W-B303110RL-05W-S405915PC-12T-B305015KL-04W-B405920PL-05W-B402408NL-04W-B202106KL-04W-B403110RL-05W-S50PartNumber5015KL-04W-***6820PL-05W-B102408NL-04W-B302106KL-04W-***3110RL-05W-S602412PS-12W-B305920PL-04W-B106820PL-05W-B202408NL-04W-B402404KL-04W-B303110RL-05W-S703110PS-12W-B305920PL-04W-B206820PL-05W-B302408NL-04W-***2404KL-04W-B403110RL-05W-S803115FS-12T-B00-A005920PL-04W-B306820PL-05W-B402410ML-04W-B102404KL-04W-***3112KL-05W-B303115FS-12T-B10-A005920PL-04W-B402410RL-04W-B602410ML-04W-B202406GL-04W-B30KDE1205PFV2GM0503PHV2-8PMD1209PTV1-APMD2408PKB1-APMD2407PKB1-APMD2406PKV3-AKD0505PHS2GM1203PHV1-8PMD1209PTV2-APMD2408PKB2-APMD2407PKB2-APMD2406PKVX-AKD0505PHS3GM1203PHV2-8PMD1209PTV3-APMD2408PKB3-APMD2407PKB3-AHA60251V4-0000-999KD1205PHS1GM0535PEV1-8PMD2409PTB1-APMD2408PKV1-APMD2407PKV1-AKD1206PTB1KD1205PHS2GM0535P***-8PMD2409PTB2-APMD2408PKV2-A9GA0612P1K039GA0612P1H039GA0612P1H039GA0612P1K609GA0612P1K609GA0812P1S619GA0812P1S619GA0812P1H619GA0812P1H619GA0824P1S619GA0824P1S619GA0824P1H619GA0824P1H619GA0912P4J039GA0912P4J039GA0912P4G039GA0912P4G039GA0912P4S039GA0912P4S039GA0924P4J039GA0924P4J039GA0924P4G039GA0924P4G039GA0924P4S039GA0924P4S039GA0912P1H039GA0912P1H039GA0312P3K0019GA0312P3J0019GA0312P3G0019GA0412P7G0019GA0412G70019GA0412H70019GA0405P6H0019GA0405P6F0019GA0412P6G0019GA0412P6H0019GA0412P6F0019GA0424P6G0019GA0424P6H0019GA0424P6F0019GA0412P3K019GA0424P3J0019GA0424P3G0019GA0424P3H0019GA0424P3M0019GA0512P7G0019GA0512P7A0019GA0512P7H0019GA0512P7M0019GA0524P7G0019GA0524P7A0019GA0524P7H0019GA0524P7M0019GA0612G7019GA0612H7019GA0612M7019GA0612L7019GA0624P1J039GA0812P7G0019GA0812P7S0019GA0824P7G0019GA0824P7S0019GA0812H70019GA0824H70019GA0812P6G0019GA0812P6M0019GA0824P6G0019GA0824P6M0019GA0812P4J0019GA0812P4G0019GA0812P4H0019GA0824P4J0019GA0824P4G0019GA0824P4H0019GA0812P2S0019GA0812P2H0019GA0812P2M0019GA0824P2S0019GA0812P1G619GA0948P1H039WS0812H4019WS0812F4019WS0812M4019WS0824H4019WS0824F4019WS0824M4019WS0912H4019WS0912F4019WS0912M4019WS0912L4019WS0924H4019WS0924F4019WS0924M4019WS0924L4019WP0924F4019WP0924B4019WP1212H1019WP1224H1019WP1248H1019WG1212G101-EEFB1724VHG9WG1212E101-E9WG1212H101-E9WG1212F101-E9WG1212M101-E9WG1224G101-E9WG1224E101-E9WG1224H101-E9WG1224F101-E9WG1224M101-E9WG1248G101-E9WG1248E101-E9WG1248H101-E9WG1248F101-E9WG1248M101-E9WS1212H1019WS1212M1019WS1224H1019WS1224M1019WS1248H1019WS1248M101109W1412H101-U109W1412M101-U109W1
