2) Any one of 1 to 4 is specified by n.
In the case of n=0, instruction is not processed.
3) In the case of 1 ≤ n ≤ 3, higher (4×(4-n)) bits of the device specified by are 0.
For example, in the case of n=3, lower 4 bits of to ( +2) are stored in b0 to b11 of , and
higher 4 bits of are 0.

Error
In the following case, it is an operation error, error flag M8067 is turned ON, and error code is stored in
D8067.
1) When to ( +n) exceeds the device range of the specified devices. (Error code: K6706)
2) When n is specified other than 0 to 4. (Error code: K6706)
Program example
