y Note:
1. If S is used in device F, only 16-bit instruction is applicable.
2. Range of n: 0 ~ 15 (16-bit instruction); 0 ~ 31 (32-bit instruction)
16-bit instruction (7 Steps)

y Flags: None
Operands:
S
: Source device
D
: Device for storing check result
n
: Bits specified for check
Explanations:
When the n
th
bit of S is “1”, D = On; when the n
th
bit of S is “0”, D = Off.
Program Example:
1. When X0 = On, assume the 15
th
bit of D0 is “1”, and M0 = On. Assume the 15
th
bit of D0 is “0”,
and M0 = Off.
2. When X0 goes Off, M0 will remains in its previous status.
