Operands
| Operand | Description |
|---|---|
| S | The first operand. Entries are gray code DWORD data registers or constants. The value range is 0 ~ 4,294,967,295 (232-1) (gray code). |
| D | The second operand. Entries are only DWORD data registers. This is where the conversion is saved. |
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 converting S exceeds the value range of the data register D. F11.0 turns ON when the value of the data for S is negative.
Signed Overflow
DWORD data register entry behaves as follows:
- If the value of D exceeds the smallest signed value -2,147,483,648, the value will be set to -2,147,483,648 with no warning.
- If the value of D exceeds the largest signed value 2,147,483,647, the value will be set to 2,147,483,647 with no warning.
Ladder Diagram Examples
DGBIN
The DGBIN instruction converts a gray code DWORD value, S, into a binary DWORD value and saves the conversion in an assigned DWORD data register, D.
When the contact, M2.0, is powered ON (1), the value of the gray code WORD data register, D50, 943,761, is converted into binary notation. The value of the conversion, 768,798, is saved in the WORD data register, D53.
Memory Monitor
DGBINP
The DGBINP one-shot instruction converts a gray code DWORD value, S, into a binary DWORD value and saves the conversion in an assigned DWORD data register, D. Every time this instruction executes, it energizes the output only once.
When the contact, M2.1, is powered ON (1), the value of the gray code WORD data register, D56, 56,457,585, is converted into binary notation. The value of the conversion, 40,480,338, is saved in the WORD data register, D59.
