1，编程语言plc的编程方式有这么几个，梯形图语言(LD)、指令表语言（IL）、功能模块图语言(FBD)、顺序功能流程图语言(SFC)、结构化文本语言(ST)。其中梯形图类似于继电器电路，被电气控制人员广泛接纳，新手推荐采用梯形图进行编程，而单片机的编程语言，我记得在大学时书上是用汇编语言吧，各种指令代码真看的痛不欲生啊，后边接触C语言了还好些，跑马灯程序的还隐约记得，相比于plc单片机的编程要更难一些尤其越到后面越难，需要计算机基础会更好一点。

平方毫米=7千瓦左右。10平方毫米=10千瓦左右。16平方毫米=14千瓦左右。在家庭配电安装中、选择合适的导线当然重要，但是匹配选择合适脱扣电流值的断路器或漏电断路器来保护导线更加更加重要。即是说；即使你选择的导线足够大、如果没有合适脱扣电流值的断路器或漏电断路来保护、也会因遇上短路电流而烧坏导线的。下面我列出家庭配电常用各种规格导线匹配合适脱扣电流值的断路器或漏电断路器来保护供大家参考；（註明；前面的数字是铜芯导线的截面积“平方毫米”、后面的数字是断路器或漏电断路的脱扣电流值“A”）1平方毫米=6A。
