The market potential of PLC is huge.Not only in my country,but also in Japan,where the industry is developed,a survey shows that the proportion of mechatronics products supporting PLC accounts for 42%,and 24%are controlled by relays and contactors.Therefore,there are still many occasions where PLC needs to be applied,especially in my country.

From the perspective of technological innovation,my country’s large and medium-sized enterprises should vigorously develop CIMS(computer integrated manufacturing system),and in the machinery manufacturing plant to form an FMS flexible manufacturing system,PLC is the foundation,so the PLC market is broad.

PLC has the advantages of stability and reliability,low price,complete functions,flexible and convenient application,and convenient operation and maintenance.

PLC的市场的潜力是巨大的，不仅在我国，即使在工业发达的日本也有调查表明，PLC配套的机电一体化产品的比例占42%，采用继电器、接触器控制尚有24%。所以说，需要应用PLC的场合还很多，在我国就更是如此了。

从技术创新的角度看，我国大中型企业还要大力发展CIMS(计算机集成制造系统)，在机械制造厂要形成FMS柔性制造系统，PLC是基础，所以PLC市场是广阔的。

PLC具有稳定可*、价格便宜、功能齐全、应用灵活方便、操作维护方便的优点，这是它能持久的占有市场的根本原因，我们下面重点阐述几个问题，并研究其发展趋势。
