Operands:
S : Reference source address n : Reference bit address
Description:
1. Available range for the value in operand n : K0~K15 for the 16-bit instruction; K0~K31 for the
32-bit instruction.
2. The BLD instruction is used to evaluate the state of a bit in D0 and if that bit is ON in the
program below, the instruction will be true. If it’s OFF, the instruction will be false. n specifies
the bit in S. If bit 3 in D0 is a 1 in the program below, the instruction is true and output Y0 will
be energized. .
Program Example:
BLD D0 K3 Y0
Instruction: Operation:
BLD D0 K3 ; Load NO contact with bit
status of bit3 in D0
OUT Y0 ; Drive coil Y0
