Zusammenfassung:	The PLC ladder diagram compiling method comprises the following steps: S100, acquiring a compiling starting point element through a DFS algorithm, and compiling the starting point element; s200, judging whether the right node of the starting point element is locked or not, judging whether the left connection number of the right node is greater than 1 or not when the right node of the starting point element is not locked, and processing by adopting a first preset rule when the left connection number of the right node is greater than 1; s300, when the left connection number of the right node is not greater than 1, judging whether the left connection number of the right node is greater than 1, and when the left connection number of the right node is greater than 1, processing by adopting a second preset rule; when the left connection number of the right node is equal to 1, processing by adopting a third preset rule; and S400, when the left connection number of the right node is less than 1, processing by adoptin
