The pointer can be manually created as before and moved to an address register with LAR1 Note: LOAD normally puts something into the Accumulator except with the Address register where it takes it out of the accumulator and puts in in the address register. Paul WebMar 1, 2024 · x [ar1,p#1.5] 这个例子，要寻址址区域和确切址数值单元，都未事先确定，确定了存储大小，这就是意味着我们可以不同区域间不同址数值单元以给定区域大小进行寻址，称之为：区域间寄存器间接寻址方式，相应，这里[ar1,p#1.5] 就叫做区域间寻址指针。
WebJan 1, 2024 · +AR1和+AR2指令将ACCU1中的值视为一个INT格式的数，将该数带符号扩展至24位，加到地址寄存器内容中去。 通过这种方式，也可以将指针长度变小。 超越出字节地址的上下极限区间（0到65 535）不会造成更多的影响。 只是端部的位被截断而已。 +ARn P#n.m 指令是将一个内部区域指针加到指定的地址寄存器中去，该区域指针P#n.m的最大 … WebMar 14, 2015 · This board is for PLC Related Q&A ONLY.
