Operands
| Operand | Description |
|---|---|
| S | The first operand. Entries are only 3 ASCII WORD data registers. This is the value to be converted to binary decimal notation. |
| D | The second operand. Entries are only WORD data registers. This is where the conversion is saved. The signed value range for the converted result is -32,768 ~ 32,767 (216). The unsigned value range for the converted result is 0 ~ 65,535 (216-1). The Hexadecimal value range for the converted result is H0000 ~ HFFFF. |
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 processing exceeds the data register assigned to D.
Instruction Behavior
The DABIN and DABINP instructions behave as follows:
- If the value of S is converted to a value less than -32,768, it will overflow to 32,767.
- If the value of S is converted to a value greater than 32,767, it will overflow to -32,768.
- The range for each digit to be converted must be H30 ~ H39. Otherwise, each digit not in range is processed as 0.
- H20, ” ” (space in ASCII), and H2D, “-” (ASCII), are omitted. The resulting binary conversion is positive.
Ladder Diagram Examples
DBINDAP
The DABIN instruction converts 3 WORD data registers, S, from ASCII code to binary decimal notation. The conversion result is saved in an assigned WORD data register, D.
When the contact, M1.0, is powered ON (1), the DABIN instruction converts three ASCII data registers, D15, D16, and D17, into binary.
The result of the conversion is saved in the WORD data register, D19.
Memory Monitor
DBINDAP
The DABINP one-shot instruction converts 3 WORD data registers, S, from ASCII code to binary decimal notation. The conversion result is saved in an assigned WORD data register, D. Every time this instruction executes, it energizes the output only once.
When the contact, M1.1, is powered ON (1), the DABINP instruction converts three ASCII data registers, D25, D26, and D27, into binary.
The result of the conversion is saved in the WORD data register, D29.
