Accumulator / Stack Load and Output Data Instructions
DL105 PLC User Manual, 3rd Edition
In the example below, when C0 is on, the value 4545 that was on top of the stack is
moved into the accumulator using the Pop instruction The value is output to V2000
using the Out instruction. The next Pop moves the value 3792 into the accumulator
and outputs the value to V2001. The last Pop moves the value 7930 into the
accumulator and outputs the value to V2002. Please note if the value in the stack
were greater than 16 bits (4 digits) the Out Double instruction would be used and two
V--memory locations for each Out Double must be allocated.
