产品详细资料
以太网全局数据定时以太网接口和PLC CPU共享内部存储器,用于以太网全局数据操作。在生产PLC中,CPU在以太网接口请求时使用数据样本更新其共享内部存储器。更新仅影响特定交换的PLC扫描长度,对PLC平均扫描时间几乎没有影响。当以太网接口的生产者周期到期时,它将从共享的内部存储器中产生数据样本到网络上。在消费型PACSystems PLC中,一旦以太网接口从网络获取数据样本,共享内部存储器就会更新。没有用户可配置的消费周期。在以太网接口通知CPU新数据已到达特定交换后,CPU在扫描结束时从共享内部存储器更新其参考表。数据在接收到后的下一次PLC扫描中可供应用程序使用。一些其他类型的以太网接口实现了消耗周期定时器。
Ethernet Global Data Timing The Ethernet interface and PLC CPU share internal memory for Ethernet Global Data operations.In the producing PLC, the CPU updates its shared internal memory with a data sample when requested by its Ethernet interface. The update affects the length of the PLC sweep only for that specific exchange and will have little effect on the PLC average sweep time. When the Ethernet interface’s producer period expires, it produces the data sample from shared internal memory onto the network. In a consuming PACSystems PLC, shared internal memory is updated as soon as the Ethernet interface gets a data sample from the network. There is no user-configurable consumer period. The CPU updates its reference tables from shared internal memory at the end of the sweep after it is notified by the Ethernet interface that fresh data has arrived for a specific exchange. The data is made available to the application on the next PLC sweep after it is received. Some other types of Ethernet interfaces implement a consumption period timer.
