Operands
| Operand | Description |
|---|---|
| S | The first operand. Entries are only WORD data registers. This is the starting data register to move to D. The signed value range for each data register is -32,768 ~ 32,767 (216). The unsigned value range for each data register is 0 ~ 65,535 (216-1). The Hexadecimal value range for each data register is H0000 ~ HFFFF. |
| D | The second operand. Entries are only WORD data registers. This is the starting data register to move the values of the data registers S ~ Sn to. |
| n | The third operand. Entries are WORD data registers or constants. This is the number of S data registers to be transferred to D. The value range is 1 ~ 32,767. |
Notice
Error Flag (F11.0) Notice
The error flag, F11.0, will be ON for one scan when the address of the data register assigned by @D exceeds the range of the data register, D. The range of the data register, D, is dependent on the CPU type. F11.0 turns ON when the value of the data for transferring S exceeds the value range of the data register D. F11.0 turns ON when the value of the data for n exceeds the value range 1 ~ 32,767 (215-1).
Instruction Behavior
The BMOV and BMOVP instructions behave as follows:
- The instructions will not execute if the value of n is less than 1 or greater than 32,767.
- Transferring data registers is possible even in the case of overlap between the data registers S and D.
- Overlap can happen when the number of transferred data registers is larger than the distance between the data registers S and D.
Ladder Diagram Examples
BMOV
The BMOV instruction transfers the WORD value of S + n data registers to D + n WORD data registers.
When the contact, M0.0, is powered ON (1), the instruction copies the values of the 3 data registers, D14, D15, and D16, into the data registers, D18, D19, and D20.
Memory Monitor
BMOVP
The BMOVP one-shot instruction transfers the WORD value of S + n data registers to D + n WORD data registers. Every time this instruction executes, it energizes the output only once.
When the contact, M0.1, is powered ON (1), the instruction copies the values of the 4 data registers, D20, D21, D22, and D23, into the data registers, D25, D26, D27, and D28.
