模块一、文章内容概要
? 3SK2、Profinet 模块及 PLC 组态及参数设置
? 3SK2 和 PLC 之间循环通讯
? 4 3SK2 和 PLC 之间循环通讯
二、 3SK2 、Profinet 模块及 PLC 组态及参数设置
1. 添加新硬件
首先打开 Portal 软件，新建项目后， 我们首先添加 3SK2 安全继电器的 基本单元：
1) 双击添加新设备
2) 点击选择控制设备
3) 双击选择需要添加的 3SK2 安全继电器
4) 点击确定
2. 添加通讯模块
基本单元添加成功后 ,添加 Profinet 模块
1) 点击设备组态
2) 将 Profinet 通讯模块拖入 2 号槽位
3) 设置 IP 地址
4) 设置设备名称
3. 参数分配 在参数分配的设备响应中可以设置过程数据结构。数据结构分为 32DI/DO 和 64DI/DO
两种长度，可根据项目需求选择数据长度。 在过程数据结构选择 32 和 64 位两种数据长
度后，在硬件组态界面的 I 地址和 Q 地址长度将会有对应的变化。
4.程序编译下载 3SK2 组态完成后，需要下载至 3SK2 设备 首先连接 PC 电缆至 3SK2 设备，并按如下步
骤 *** 作： 1) 点击编译 2) 点击下载 3) 选
