Processing details
• The data specified with (S2) is added to the data specified with (S1).
• When (S1) and (S2) differ in data type, the data of the smaller data type is converted into that of the greater type before
operation is performed.
Operation error
An operation error will occur if:
• (S1) or (S2) is an indirectly specified device and its device No. is outside the range.
Program example
■Program which substitutes the result of adding K123 and #0 to W0
W0 = K123 + #0
W0 579
■Program which substitutes the result of adding #0F and #10 to D0L
D0L = #0F + #10
D1 D0
D0L 12468
The 64-bit floating-point type data are used for addition, and the result is converted into the 32-bit integer type and then
substituted.
