LWN2660-6自动化模块
机械数据
根据DIN EN 50022–35，安装在DIN导轨上，深15 mm。
DIN导轨位于上部和模块的下边缘。使用4个M4螺钉用螺钉紧固。宽x高x深240 x 140 x 85毫米用螺钉式可拆卸接线板接线的方法端子，导线横截面最大2.5 mm2重量1.6 kg
尺寸（安装）见下图。设备深85 mm。接口连接器COM1和COM2设置得更深，以便安装即使使用可拆卸的接口电缆，所需的深度也不会变大。但是，如果使用DIN导轨，安装深度随导轨的总深度增加而增加。处理时间中心应用最重要的时间机组07 KR 91/07 KT 92/07 KT93，带或不带连接的远程模块包括：反应时间tkk是信号之间的时间输入端的转换和信号响应在输出端子。对于二进制信号，反应时间包括输入延迟tD，程序的周期时间tC处理和总线传输时间，如果系统通过远程模块进行扩展。
循环时间tC确定以下时间间隔处理器开始执行用户再次编程。周期时间必须由用户指定。它应该大于用户程序、数据传输时间和相关等待时间。
循环时间也是一些时间控制功能，如PID控制器。
程序处理时间tUP是处理用户程序。
用于配置和确定反应time tkk，需要执行以下步骤：
–确定程序处理时间tUP
–添加循环内的其他时间时间tC
–循环时间tC的规格
–确定总线周期时间tb（如果有）连接到中央单元的远程模块–反应时间tkk为输入延迟tv的总和，2 x总线周期时间tb和2 x周期时间tC和输出延迟t必须执行的操作。除了根据第A1.2章（附录），可以测量程控中央单元的容量利用率RUN/STOP开关设置为RUN。的菜单项编程软件907中的“显示PLC状态”PC 331可用于此目的。增加周期时间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 %.
