RPI是為服務(wù)器上的特定數(shù)據(jù)段指定的更新速率
網(wǎng)絡(luò)將模塊添加到控制器的I/O配置時，
必須輸入RPI作為參數(shù)。此值指定執(zhí)行的頻率
生成該模塊的數(shù)據(jù)。例如，如果指定的RPI為
50ms，這意味著每隔50ms，I/O模塊應(yīng)將其數(shù)據(jù)發(fā)送到
控制器或控制器應(yīng)將其數(shù)據(jù)發(fā)送到I/O模塊。
為ControlNet運行RSNetWorx時，實際的數(shù)據(jù)包間隔（API）
將進(jìn)行計算。API將等于或快于RPI。
RPI僅用于生成數(shù)據(jù)的模塊。例如，當(dāng)?shù)氐腃NB
模塊不需要RPI，因為它不是數(shù)據(jù)生成成員
系統(tǒng)的功能；它僅用作連接遠(yuǎn)程機(jī)架的橋梁。
重要提示：不能將RPI設(shè)置為比螺母快的速率。這個
網(wǎng)絡(luò)無法以比NUT更快的速度發(fā)送數(shù)據(jù)。The RPI is the update rate specified for a particular piece of data on the network. When you add a module to the I/O configuration of a controller, you must enter the RPI as a parameter. This value specifies how often to produce the data for that module. For example, if you specify an RPI of 50ms, it means that every 50ms the I/O module should send its data to the controller or that the controller should send its data to the I/O module. When you run RSNetWorx for ControlNet an Actual Packet Interval (API) will be calculated. The API will be equal to or faster than the RPI. RPIs are only used for modules that produce data. For example a local CNB module does not require an RPI because it is not a data-producing member of the system; it is used only as a bridge to remote racks. Important:You cannot set the RPI to a rate faster than the NUT. The network cannot send data at a rate that is faster than NUT.
