詳細內容:Measurex 08597000 plccpu負責開關量、模擬量的采集、運算,實施直接的控制功能;通訊模塊cmm311通過兩個通訊口分別連接上位機及觸摸屏,實現人機界面與plc的數據通訊;pcm模塊的com2與westinghouse(西屋儀表)mintii網絡轉換器相連,負責通過mintii網絡轉換器與現場三個種類的12臺westinghouse儀表通訊,采集電流、電壓、功率等各種物理量的實時數據,同時,com1在調試完畢后用來與現場一臺三菱fx2nplc通訊,實現從geplc系統到fx2n系統的數據通路,方案圖如圖1所示。 2.1minitii轉換器通訊協議簡介 在這個方案中,minitii與下位設備的硬件連接為雙絞線,minitii及下位各設備都并入雙絞線組成的westinghouseincom網絡,在該網絡中各通訊主體使用二進制通訊方式,數據幀均由33位二進制數構成,minitii充當主站(master)角色,對下位各設備發起通訊,進行輪詢。 pcm311模塊與minitii轉換器進行的是ascii碼通訊方式,而minitii轉換器與下位dt3000、mp3000、iq200各系列設備的通訊方式為二進制碼通訊,實際上minitii所起到的作用是將pcm模塊發出的ascii碼指令幀轉譯為二進制碼指令幀,當然,在通訊過程中,我們只需關心ascii碼通訊幀的格式,minitii會自動將其轉為二進制格式后發到incom網絡中去。 ABB VFD ACS501-015-4-00P5 440- 500VAC 20HP vt ALLEN BRADLEY 1326AB-B515E-21-L USED 1326ABB515E21L ABB PST60-600-70 ABB EH300C-YL11 EH300 EH 300 CONTACTOR 24V DC COIL ABB 4640/500AM DISSOLVED OXYGEN ANALYZER 9408 NEW Asea Brown Boveri ABB Axodyn Servo Drive D05010/R0004 ABB Servo Motor RSY264.30-2 R4-4/S23/S60 ABB MOD 300 BULK POWER SUPPLY 6024NR14130 ABB GNT2009454R0004/05MA22G SERVO DRIVE 15/40A ABB DSDX 453/5716075-AN PLC HP ProCurve (J4904A#ABB) 48-Ports External Switch NEW YB560101-SV ABB ABB FREQUENCY INVERTER ACS 401 60 20 32 25 HP 460V ALLEN BRADLEY 1326AB-B515E-21-K5 USPP 1326ABB515E21K5 ABB Pole Mount Wet Transformer 25KVA 12470HV 120/240LV ABB DSDI 452 Master Digital 5716075-E/3 used DSDI452 TAYLOR ABB MOD 300 D/F BOARD 6005BZ10000E ABB Serial Measurement Unit 3HAC 022286-001/05 #29678 ABB Contactor, EH300, EH300C-1, All coils, NEW OEM ABB DSQC236C AXIS DRIVE BOARD YB560103-CC ABB ACS501-020-4-00P2 20HP AC DRIVE ABB 05MA22D/05-MA-22-D SERVO DRIVE 15/40A 200V ALLEN BRADLEY 1326AB-B530E-21 USPP 1326ABB530E21 ALLEN BRADLEY 1326AB-B420-HS2K4L USPP 1326ABB420HS2K4L ALLEN BRADLEY 1326AB-B420-ES2K4L USPP 1326ABB420ES2K4L ABB DSQC303 3HAA3573-ADA ROBOT 3HAA3573ADA DSQC 303 ABB DSQC209 YB560103-AL ROBOT SERVO AMP YB560103AL ABB SACE S4N250BW 250 amp circuit breaker ABB Inverter ACS550-01-023A-4 (ACS55001023A4) ABB AM54072 DN50 Armored Variable Area Flowmeter ABB PC BOARD DSQC 236T ABB HVAC DRIVE ACH550-UH-023A-4 ABB HVAC Drive ACH550-UH-059A-4 ABB 52590493 Ulma 2010/2020 Stromberg ABB ACH 401601632 ADJUSTABLE FREQUENCY AC DRIVE AB 1326AB-B720F-21 1326ABB720F21 SERVO MOTOR 460V NEW ABB ACH 500 Variable Frequency Motor Starter #11142 ABB 38SC980004R821 BOARD NEW 38SC980004R821 ABB YB560103-CH DSQC239 REMOTE I/O BOARD ABB TaylorElectronics Field Bus Controller 6227BZ10200D ABB 3HAB 2136-1/4 ROBOT TEACH PENDANT ABB MOD 300 FIELD BUS MODULE 2-CHANNEL P/N 6204BZ10200 ASEA Brown Boveri, ABB YYT 102C
