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. When BON is used as 16-bit instruction, Z device cannot be adopted; when BON is used as 32-bit instruction,
V device cannot be adopted.
3. When specifying the bit device of KnX(Y/M/S), the starting No. should be a multiple of 16 in octal or decimal
format. For example, K1X0, K4Y20 (octal); K1M0, K4S16 (decimal).
4. 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.
