LWN2660-6自動化模塊
機(jī)械數(shù)據(jù)
根據(jù)DIN EN 50022–35，安裝在DIN導(dǎo)軌上，深15 mm。
DIN導(dǎo)軌位于上部和模塊的下邊緣。使用4個M4螺釘用螺釘緊固。寬x高x深240 x 140 x 85毫米用螺釘式可拆卸接線板接線的方法端子，導(dǎo)線橫截面最大2.5 mm2重量1.6 kg
尺寸（安裝）見下圖。設(shè)備深85 mm。接口連接器COM1和COM2設(shè)置得更深，以便安裝即使使用可拆卸的接口電纜，所需的深度也不會變大。但是，如果使用DIN導(dǎo)軌，安裝深度隨導(dǎo)軌的總深度增加而增加。處理時間中心應(yīng)用最重要的時間機(jī)組07 KR 91/07 KT 92/07 KT93，帶或不帶連接的遠(yuǎn)程模塊包括：反應(yīng)時間tkk是信號之間的時間輸入端的轉(zhuǎn)換和信號響應(yīng)在輸出端子。對于二進(jìn)制信號，反應(yīng)時間包括輸入延遲tD，程序的周期時間tC處理和總線傳輸時間，如果系統(tǒng)通過遠(yuǎn)程模塊進(jìn)行擴(kuò)展。
循環(huán)時間tC確定以下時間間隔處理器開始執(zhí)行用戶再次編程。周期時間必須由用戶指定。它應(yīng)該大于用戶程序、數(shù)據(jù)傳輸時間和相關(guān)等待時間。
循環(huán)時間也是一些時間控制功能，如PID控制器。
程序處理時間tUP是處理用戶程序。
用于配置和確定反應(yīng)time tkk，需要執(zhí)行以下步驟：
–確定程序處理時間tUP
–添加循環(huán)內(nèi)的其他時間時間tC
–循環(huán)時間tC的規(guī)格
–確定總線周期時間tb（如果有）連接到中央單元的遠(yuǎn)程模塊–反應(yīng)時間tkk為輸入延遲tv的總和，2 x總線周期時間tb和2 x周期時間tC和輸出延遲t必須執(zhí)行的操作。除了根據(jù)第A1.2章（附錄），可以測量程控中央單元的容量利用率RUN/STOP開關(guān)設(shè)置為RUN。的菜單項(xiàng)編程軟件907中的“顯示PLC狀態(tài)”PC 331可用于此目的。增加周期時間tC，直到容量利用率低于80%。
Mechanical data
Mounting on DIN rail according to DIN EN 50022–35, 15 mm deep.
The DIN rail is located in the middle between the upper
and the lower edges of the module.
Fastening by screws using 4 M4 screws.
Width x height x depth 240 x 140 x 85 mm
Wiring method by removable terminal blocks with screw-type
terminals, conductor cross section max. 2.5 mm2
Weight 1.6 kg
Dimensions (for mounting) see the following drawing The device is 85 mm deep. The interface connectors COM1 and COM2 are set deeper so that the mounting
depth required does not become any larger even with detachable interface cables. If, however, a DIN rail is used,
the mounting depth is increased by the overall depth of the rail.
Processing times The most important times for the application of the central units 07 KR 91 / 07 KT 92 / 07 KT 93 with or without connected remote modules are: The reaction time tkk is the time between a signal transition at the input terminal and the signal response at the output terminal. In case of binary signals, the reaction time consists of the input delay tD, the cycle time tC of the program processing and the bus transmission time, if the system is expanded by remote modules. The cycle time tC determines the time intervals after which the processor starts the execution of the user program again. The cycle time has to be specified by the user. It should be greater than the program processing time tUP of the user program, the data transfer times and the related waiting times. The cycle time is also the time base for some time-controlled functions, such as for the PID controller. The program processing time tUP is the net time for processing the user program. For the configuration and for determining the reaction time tkk, the following steps are necessary: – Determining the program processing time tUP – Addition of the other times which are within the cycle time tC – Specification of the cycle time tC – Determining the bus cycle time tb, if there are any remote modules connected to the central unit – Reaction time tkk as the sum of the input delay tv, 2 x bus cycle time tb and 2 x cycle time tC and output delay tDO. In addition to calculating the cycle time tC in accordance with chapter A1.2 (Appendix) it is possible to measure the capacity utilization on the programmed central unit – with the RUN/STOP switch set to RUN. The menu item of ”Display PLC status” in the programming software 907 PC 331 can be used for this purpose. Increase the cycle time tC until the capacity utilization is below 80 %.
