Operands:
S: Reference source device n: Reference bit
Explanations:
1. For ES2/EX2 models, only V1.20 or above supports the function.
2. Available range for the value in operand n: K0~K15 for 16-bit instruction; K0~K31 for 32-bit
instruction.
BLD instruction is used to load NC contact whose contact state is defined by the reference bit n in
reference device D, i.e. if the bit specified by n is ON, the NC contact will be ON, and vice versa.
