Operands:
S
: Source device
D
: Device for storing check result
n
: Bits specified for check
Explanations:
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)
3. See the specifications of each model for their range of use.
4. 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.
