Operation :
The contents of the source device (S) are written to
the FIFO stack. The position of insertion into the
stack is automatically calculated by the PLC.
The destination device (D) is the head address of
the FIFO stack. The contents of D identify where the
next record will be stored (as an offset from D
If the contents of D exceed the value “n-1” (n is the
length of the FIFO stack) then insertion into
the FIFO stack is stopped. The carry flag M8022 is
turned ON to identify this situation.
