5 How to Specify Devices and Constants to Instructions
5.7 Indexing
In the case of constants
The indexing operation is explained in an example in which the
transfer destination in MOV instruction is indexed with the index
register V6 (as shown in the figure on the right).
Transfer K0 or K20 to the index register V6 in advance.
When X005 is set to ON, "K(6+0) = K6" is realized if V6 is "0", and
K6 is transferred to D10.
When X005 is set to ON, "K(6+20) = K26" is realized if V6 is "20",
and K26 is transferred to D10.
