1．存儲(chǔ)容量
存儲(chǔ)容量是指用戶程序存儲(chǔ)器的容量。用戶程序存儲(chǔ)器的容量大，可以編制出復(fù)雜的程序。一般來(lái)說(shuō)，小型PLC的用戶存儲(chǔ)器容量為幾千字，而大型機(jī)的用戶存儲(chǔ)器容量為幾萬(wàn)字。
2．I/O點(diǎn)數(shù)
輸入/輸出（I/O）點(diǎn)數(shù)是PLC可以接受的輸入信號(hào)和輸出信號(hào)的總和，是衡量PLC性能的重要指標(biāo)。I/O點(diǎn)數(shù)越多，外部可接的輸入設(shè)備和輸出設(shè)備就越多，控制規(guī)模就越大。
3．掃描速度
掃描速度是指PLC執(zhí)行用戶程序的速度，是衡量PLC性能的重要指標(biāo)。一般以掃描1K字用戶程序所需的時(shí)間來(lái)衡量掃描速度，通常以ms/K字為單位。PLC用戶手冊(cè)一般給出執(zhí)行各條指令所用的時(shí)間，可以通過(guò)比較各種PLC執(zhí)行相同的操作所用的時(shí)間，來(lái)衡量掃描速度的快慢。
4．指令的功能與數(shù)量
指令功能的強(qiáng)弱、數(shù)量的多少也是衡量PLC性能的重要指標(biāo)。編程指令的功能越強(qiáng)、數(shù)量越多，PLC的處理能力和控制能力也越強(qiáng)，用戶編程也越簡(jiǎn)單和方便，越容易完成復(fù)雜的控制任務(wù)。
5．內(nèi)部元件的種類(lèi)與數(shù)量
在編制PLC程序時(shí)，需要用到大量的內(nèi)部元件來(lái)存放變量、中間結(jié)果、保持?jǐn)?shù)據(jù)、定時(shí)計(jì)數(shù)、模塊設(shè)置和各種標(biāo)志位等信息。這些元件的種類(lèi)與數(shù)量越多，表示PLC的存儲(chǔ)和處理各種信息的能力越強(qiáng)。
6．特殊功能單元
特殊功能單元種類(lèi)的多少與功能的強(qiáng)弱是衡量PLC產(chǎn)品的一個(gè)重要指標(biāo)。近年來(lái)各PLC廠商非常重視特殊功能單元的開(kāi)發(fā)，特殊功能單元種類(lèi)日益增多，功能越來(lái)越強(qiáng)，使PLC的控制功能日益擴(kuò)大
7．可擴(kuò)展能力
PLC的可擴(kuò)展能力包括I/O點(diǎn)數(shù)的擴(kuò)展、存儲(chǔ)容量的擴(kuò)展、聯(lián)網(wǎng)功能的擴(kuò)展、各種功能模塊的擴(kuò)展等。在選擇PLC時(shí)，經(jīng)常需要考慮PLC的可擴(kuò)展能力。
