Chapter 5: Standard RLL Instructions - Accumulator/Stack Load and Output Data
Load (LD)
1
The Load instruction is a 16-bit instruction that loads the value
230
(Aaaa), which is either a V-memory location or a 4-digit
240
2
constant, into the lower 16 bits of the accumulator. The upper
250-1
16 bits of the accumulator are set to 0.

NOTE: Two consecutive Load instructions will place the value of the first load instruction onto the
8
accumulator stack.
In the following example, when X1 is on, the value in V2000 will be loaded into the
9
accumulator and output to V2010.
