2.產(chǎn) 品 詳 情 資 料：
DEIF DVC550控制主板卡件顯示要求——DEIF DVC550具有串行端口，通常用于與HMI或操作員接口（OI）設(shè)備通信。時(shí)間（TOD）時(shí)鐘要求-嵌入式CPU沒(méi)有，模塊化CPU有。系統(tǒng)大小限制-如果接近系統(tǒng)的最大模塊數(shù)量限制，則可以使用具有雙重功能的模塊來(lái)節(jié)省機(jī)架插槽。例如，DEIF DVC550在一個(gè)模塊中具有CPU和以太網(wǎng)通信能力。DEIF DVC550在一個(gè)模塊中具有CPU和串行通信能力。有離散和模擬組合I/O模塊，在一個(gè)模塊中提供有限數(shù)量的輸入和輸出。此外，與密度較低（16點(diǎn)及以下）的I/O模塊相比，32點(diǎn)分立I/O模塊節(jié)省了機(jī)架插槽。您還可以使用Genius塊或現(xiàn)場(chǎng)控制分布式I/O來(lái)滿足額外I/O的需要，因?yàn)檫@些不需要PLC插槽；它們通過(guò)通信總線與PLC通信
Display requirements - DEIF DVC550have serial ports that are often used to communicate with HMI or Operator Interface (OI) devices. ? Time of day (TOD) clock requirements - The Embedded CPUs do not have one, the Modular CPUs do. ? System size limitation - If you are close to the maximum number of modules limit of your system, you can use modules that have dual functions to conserve rack slots. For example, theDEIF DVC550has CPU and Ethernet communications capability in one module. DEIF DVC550 and Serial Communications capability in one module. There are discrete and analog combination I/O modules that provide a limited number of both inputs and outputs in one module. Also, the 32-point discrete I/O modules conserve rack slots compared with lower density (16-point and less) I/O modules. You may also be able to use Genius Blocks or Field Control distributed I/O to accommodate the need for additional I/O, since these do not require a PLC slot; they communicate with the PLC over a communications busDEIF DVC550
