當(dāng)前中小型PLC比較多，為了適應(yīng)市場的多種需要，今后PLC要向多品種方向發(fā)展，特別是向大型和小型兩個(gè)方向發(fā)展。現(xiàn)已有I/O點(diǎn)數(shù)達(dá)14336點(diǎn)的大型PLC，其使用32位微處理器，多CPU并行工作和大容量存儲器，功能強(qiáng)。

 小型PLC由整體結(jié)構(gòu)向小型模塊化結(jié)構(gòu)發(fā)展，使配置更加靈活，為了市場需要已開發(fā)了各種簡易、經(jīng)濟(jì)的小型微型PLC，*小配置的I/O點(diǎn)數(shù)為8～16點(diǎn)，以適應(yīng)單機(jī)及小型自動控制的需要，如三菱公司α系列PLC。
