the instruction statement list was written down into plc processor by entering instruction of 「write down」 through connecting computer with plc processor by cable.
用编程电缆连接计算机和plc主机,执行「写出」操作,将指令语句表写出到plc主机。
the 「write down」 programme was to make the instruction programme of statement list written down into the random of subscriber programme of plc processor.

although this requirement usually is met by using a jump statement, the following case also is valid, because the end of the statement list cannot be reached.
虽然通常使用跳转语句满足此要求,但以下情况下也有效,因为无法到达语句列表的末尾。
transformation algorithm between the ladder diagram and the statement list based on the aov diagraph and the cause and effect diagraph for programmable logic controller(plc) systems is proposed.
