10 Application Instructions API 202-313 Operands: S : Reference source device n : Reference bit Explanations: 1. EH2/SV_V1.9 and versions above, and EH3/SV2 supports the function. EH series does not support the dunction. 2. Available range for the value in operand n : K0~K15 for 16-bit instruction; K0~K31 for 32-bit instruction. 3. 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. Program Example: Y0 Instruction: Operation:
