FM350-1计数模块(最新整理)

1、本手册应用一个特例来介绍你开动fm350-1模块。以下将分四步介绍功能程序，你可以计算开关次数，测试fm350-1 的基本硬件和软件功能。本手册将给你一个初始的认识。本手册以序号a5e00073040-01的 fm350-1 模块为例。根据你经验情况，完成本例大概需要1-2小时时间。要求：1. s7-300站（含电源模块和cpu）2. 编程设备必须正确地安装step 7 (.v4.02以上)，(本例在step 7 v5.0中完成)。3. 必须已经为s7-300站建立项目4. 编程设备能连接到cpu。5. 必须有fm350-1模块一块，fm350-1配套包，及附件accessories例如：总线

2、连接器a bus connector,前端连接器front connector, 传感器或开关sensors or switches, 和电缆and wiring material configuration package：配套（软件）包在编程设备上安装配套配套包（手册-第 5 章）fm350-1配套包包括fm350-1配置工具，功能(fc)和必要的数据结构(udt)，及一个程序例子。安装 fm350-1 模块及接线（手册-第 3、4 章）coding key的位置.：参照1.3节，3.2节d：24v模块的安装和连接：参照3.2节前端连接器的接线和管脚分配：参照第4章测试：打开电源模块的开关

3、，红灯sf亮，fm350-1将进入预设的默认状态，默认设置参照4.3节。给 fm350-1 分配参数：从simatic manager.中打开项目，并打开硬件配置。从硬件目录选择正确的定购号的fm350-1模块，并拖至所需的插槽（本例中：插槽4） 双击fm350-1模块，定义参数分配，并保存设置。 operating modes: 0 to +32 bit, continuous counting, hardware gate encoders: 24v initiator, p switch inputs: level-controlled hardware gate process int

4、errupt enable: not possible as deselected in basic parameters outputs: dq0 inactive, dq1 inactive reaction to cpu stop: stop在配置时输入fm350-1的参数分配，在菜单中文件保存（file save），然后关闭参数配置窗口。在你的项目中保存你所创建的配置。stationsave and compile.在plc停止运行模式下下载配置。plc download to module数据现在便直接下载到cpu和fm350-1中了。sf红灯熄灭了，以后后配置将保存在cpu缓存中，

5、每次cpu从stoprun时，数据将从cpu传送到fm350-1中。transfer测试：现在你可以运行简单的测试而不需要程序。关闭这gate contact: i0 绿灯就亮起来.close and open the count contact several times: you can monitor the state of the least significant bit of the fm 350-1 counter via the green led cr.note that a mechanical count contact can bounce.when you open

6、 the gate contact, the gate led i0 extinguishes and no more switchingoperations are counted (有关这个功能的时序表在手册2.2节可以查阅)integrating into the user program在simatic manager中打开fmx50lib库，fileopen.libraries.复制fmx50lib中的 fc0， fc1 和用户定义数据类型udt1 到你自己的项目块中。“”“”at the end, xiao bian gives you a passage. minand once
