NI PXI-4462聲音和振動(dòng)模塊比較EPROM和EEPROM功能對(duì)于一次性應(yīng)用，EEPROM是兩者中更實(shí)用的。它可以在PLC本身中創(chuàng)建，不需要任何額外的外部設(shè)備。EPROM的創(chuàng)建并不方便。必須使用EPROM燃燒器在PLC外部創(chuàng)建。由于EPROM比EEPROM便宜，如果您需要復(fù)制程序的多個(gè)副本以用于大量相同的控件，使用EPROM可能具有成本效益，特別是如果您已經(jīng)有了EPROM刻錄機(jī)。創(chuàng)建EPROM的步驟1。在將用于開發(fā)應(yīng)用程序的PLC的PROM插座中安裝EEPROM。NI PXI-44622.在RAM內(nèi)存中開發(fā)和調(diào)試程序，然后將其寫入EEPROM。3.從PLC中移除EEPROM，并將其作為主設(shè)備安裝在EPROM燃燒器中，以制作一個(gè)或多個(gè)EPROM。4.將空白EPROM安裝在EPROM燃燒器中，并將EEPROM上的程序復(fù)制到空白EPROM中。5.將EPROM安裝在PLC的PROM插槽中，然后將其內(nèi)容復(fù)制到RAM存儲(chǔ)器中。EPROM然后用作RAM存儲(chǔ)器的板上備份。NI PXI-4462
英文資料
Comparing EPROM and EEPROM Features For one-time applications, an EEPROM is the more practical of the two. It can be created in the PLC itself and doesn’t require any additional outside equipment. An EPROM is not as convenient to create. It must be created outside the PLC using an EPROM burner. Because an EPROM is less expensive than an EEPROM, if you need to reproduce multiple copies of a program to use on a large number of identical controls, it may be cost effective to use EPROMs, especially if you already have an EPROM burner.Procedure for Creating an EPROM 1. Install an EEPROM in the PROM socket of the PLC you will use to develop the application program. 2. Develop and debug the program in RAM memory, then write it to the EEPROM. 3. Remove the EEPROM from the PLC and install it in the EPROM burner as a master to make one or more EPROMs. 4. Install the blank EPROM in the EPROM burner and copy the program on the EEPROM to the blank EPROM. 5. Install the EPROM in the PLC’s PROM socket, then copy its contents into RAM memory. The EPROM then serves as an on-board backup to RAM memory.NI PXI-4462
