产品详细资料
通常,将生产周期配置为小于CPU完成扫描所需的时间既没有用处,也没有必要。如果交换机的生产者周期设置为低于CPU扫描时间,以太网接口将以配置的间隔发送一个过时的样本(包含与之前发送的数据相同的数据的样本)。当新的CPU数据在扫描结束时可用时,以太网接口将立即发送另一个包含新数据的样本。发送此样本时,生成的交换的计时器不会重置。这可能导致网络中的样本比从配置的周期预期的要多。5.5.2电描记图交换的可配置生产者周期电描记法交换的生产者周期可以是两毫秒(2毫秒)到一小时。在可编程逻辑控制器中,以太网接口尝试以该间隔产生数据。交换生产可能与配置的间隔相差多一个生产周期或一个生产商CPU扫描周期,以较早报告的为准。
In general, it is neither useful nor necessary to configure the production period to be less than the time it takes for the CPU to complete a sweep. If the producer period for an exchange is set lower than the CPU sweep time, the Ethernet interface will send a stale sample (a sample containing the same data as previously sent) at the configured interval. When the latest CPU data becomes available at the end of the sweep, the Ethernet interface will immediately send another sample with the latest data. The timer of the produced exchange is not reset when this sample is sent. This can result in more samples in the network than would be expected from the configured period. 5.5.2 Configurable Producer Period for an EGD Exchange The Producer period for an EGD exchange can be two milliseconds (2 ms) to one hour. In the PLC, the Ethernet interface attempts to produce the data at this interval. The exchange production may vary from the configured interval by up to one production period or one producer CPU sweep period, whichever is reported sooner.
