• In the 32-bit operation, the acquired sum is 64-bit data. FX

the sum is within the numeric range of 32-bit data (K-2,147,483,648 to K2,147,483,647), however, FX

PLCs can handle the low-order 32 bits of 32-bit data as the sum while ignoring the high-order 32 bits.

• Note that the 32-bit value [n+1, n] is valid when D or R is specified as "n" in a 32-bit instruction.

In the case of "DWSUM D0 D100 R0", "n" is [R1, R0].

An operation error is caused in the following cases; The error flag M8067 turns ON, and the error code is stored in

• When "n" points starting from

• When "n" is smaller than or equivalent to "0" (error code: K6706)

Program example

In the program shown below, the sum of 16-bit data stored in D10 to D14 is stored in [D101, D100].
