1756-OB8产品功能为了满足客户线路维护方便﹑高通讯速度及高可靠性的要求，系统采用了基于profibusdp网络的plc分布式控制方式。卸船机的***控制器采用的是西门子s7-400系列plccpu416-2dp，通过profibusdp网络与分布式站点et-200m实现通讯，dp网络的总线的波特率设置为1.5mb/s。电气房的所有et-200m站通过profibus连接到cpu,司机室的et-200m站通过光电模块(olm)以及光缆连接到电气房olm再连到cpu。交流驱动6se70及mm440通过profibus通讯板cbp2由profibus通讯电缆连接到plc，plc除了通过数据总线向驱动机构传输计算好的速度给定值﹑控制字，还要接收各机构的状态字。系统硬件配置如图3所示。1756-OB8厦门光沃自动化设备有限公司联系人：小杨电话：0592-5709821电话：18030229050***:1878187406邮箱：1878187406@***.com1756-OB8参数规格ASEABROWNBOVERI57360001-A/5USPP57360001A5ASEABROWNBOVERI57360001-A/6USPP57360001A6ALLENBRADLEY1336S-B060-AA-E​N3USPP1336SB060AAEN3ALLENBRADLEY1785-L46BNSFP1785L46BTEXASINSTRUMENTS5110-10USPP511010BALDORMB7420ABUSPPMB7420ABMITSUBISHIFR-F740-04320-N​AUSPPFRF74004320NAALLENBRADLEY1336F-BX060-AN-​ENUSPP1336FBX060ANENALLENBRADLEY150-A360NBDUSPP150A360NBDRELIANCEELECTRIC803456-3TUSPP8034563TINDRAMATMDD112D-N-030-N​2M-130PB0USPPMDD112DN030N2M1​AGEFANUCIC3600LRLB1NSPPIC3600LRLB1ALLENBRADLEY8520-3S10A-BAT-​EX4-S-1-2-3-4-5​-7USPP852ALLENBRADLEY8520-3S10A-BAT-​EX4-T1-Y-4-5-7USPP85203SALLENBRADLEY1772-ME8NSFP1772ME8FANUCA06B-0306-B131USPPA06B0306B131EECAEGFPS1623USPPFPS1623MODICONAM-***09-023USPPAM***09023TOSHIBAVFP1-4550UP-B1USPPVFP14550UPB1ALLENBRADLEY20DD125A3EYNACA​SEUSPP20DD125A3EYNACA​SALLENBRADLEY1756-L62FNFP1756L62INDRAMATDSC3.1-50-115USPPDSC3150115ALLENBRADLEY8520-3S5A-BAT-E​X4-Y-1-4USPP85203S5ABATEALLENBRADLEY1785-L40LUSPP1785L40LALLENBRADLEY7552-040USPP7552040INDRAMAT2AD132D-B35OB1-​AS03-B2V1USPP2AD132DB35OB1AS​0INDRAMAT2AD132D-B35OB1-​AS03-B2N1USPP2AD132DB35OB1AS​1LENZEEVS9331-EPUSPPEVS9331EPMARCONIASX-1000-10ACNSFPASX100010ACINDRAMATTWM1.1-100-300-​W1/115NSPPTWM11100300W111​5ENDRESS&HAUSER50P4H-EL0A1RA0B​AAAUSPP50P4HEL0A1RA0BSIEMENS6FC5110-0DB03-0​AA4NSFP6FC51100DB030AA​41756-OB8)
