S : the head ID of source devices to be added up
D : the destination device to store the amount
n : the number of consecutive devices to be accumulated
When the X0 = “ON”, this instruction accumulates the contents of D10~D14 (5 16-bit devices), then stores the
amount to the (D101, D100).
This 16-bit instruction adds up the consecutive 16-bit word devices which are started from , then store the
result to the 32-bit double word device .

The result device for this 16-bit instruction is a 32-bit device, the positive or negative sign is located at its
the Most Significant Bit (MSB = 0 = positive; MSB = 1 = negative).
