1. 设计和功能

S7-300 可以实现空间节省和式组态。除了，只需要一条 DIN 安装轨用于固定并把它们旋转到位。这样就实现了坚固而且具有 EMC 兼容性的设计。随用随建式的背板总线可以通过简单的插入附加的和总线连接器进行扩展。S7-300 系列丰富的产品既可以用于集中扩展，也可用于构建带有 ET 200M 的分布式结构；因此实现了经济高效的备件控制。扩展选件‘’如果自动化任务需要超过 8 个，S7-300 的控制器 (CC) 可以使用扩展装置 (EU) 扩展。中心架上多可以有 32 个，每个扩展装置上多 8 个。接口 (IM) 可以同时处理各个机架之间的通讯。如果工厂覆盖范围很宽，CC/EU 还可以相互间隔较长距离安装（长 10m）。在单层结构中，这可以实现 256 个 I/O 的大组态，在多层结构中多可以达到 1024 个 I/O。在带有 PROFIBUS DP 的分布式组态中，可以有 65536 个 I/O 连接（多 125 个站点，如通过 IM153 连接的 ET200M）。插槽可自由编址，因此无需插槽规则。S7-300 种类丰富，还可以用在分布式自动化解决方案中。与 S7-300 具有相同结构的 ET 200M I/O 系统通过接口不仅可以连接到 PROFIBUS 上还可以连接到 PROFINET 上。

2.产品详细说明

CompactLogix PLC提供面向低端到中型应用的Logix解决方案。典型的应用包括设备别的控制应用（只要求有限的输入输出数量以及有限的通讯要求）。Compactlogix 1769-L31提供两个串行通讯接口。1769-L32C和1769-L35CR控制器提供一个集成的ControlNet通讯口。1769-L32E和1769-L35E提供一个集成的以太网接口。 CompactLogix PLC系统支持：从中心CompactLogix控制器通过EtherNet/IP、控制网、设备网来远程控制输入输出和现场设备，实现不同地点的分布式控制。 通过将CompactLogix控制器连接到EtherNet/IP以太网或ControlNet控制网，您可以以很低的成本将一台机器或一个项目集成到一个工厂范围控制系统中去。比如：您可以使用1769-L35E控制器连接数量众多的产品，如Allen-Bradley PanelView Plus操作员界面、Point I/O、和PowerFlex 70驱动器，以实现全范围的集成解决方案
