Operands:
S: Source device D: Device for storing check result n: Bit number to be checked
Explanation:
1. The instruction checks the status of designated bit (specified by n) in S and stores the result
in D
2. If operand S uses index F, only 16-bit instruction is available.
3. Valid range of operand n : n = 0~15 (16-bit), n = 0~31 (32-bit)
Program Example:
1. When X0 = ON, and bit15 of D0 = “1”, M0 will be ON. If the bit15 is “0”, M0 is OFF.
2. When X0 is OFF, M0 will retain its previous status.
