Operands
| Operand | Description |
|---|---|
| S | The first operand. Entries are DWORD data registers or constants. This is the value to invert all bits. The signed value range is -2,147,483,648 ~ 2,147,483,647 (232). The unsigned value range is 0 ~ 4,294,967,295 (232-1). The Hexadecimal value range is H00000000 ~ HFFFFFFFF. |
| D | The second operand. Entries are only DWORD data registers. This is where the inverted bits of S are stored. |
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 inverting S exceeds the value range of the data register D.
Ladder Diagram Examples
DCML
The DCML instruction inverts every bit in the DWORD value, S, and saves the inversion in an assigned DWORD data register, D.
When the contact, M0.0, is powered ON (1), the instruction inverts the bits in the DWORD data register, D8, and saves the result in the data register, D11.
Memory Monitor
DCMLP
The DCMLP one-shot instruction inverts every bit in the DWORD value, S, and saves the inversion in an assigned DWORD data register, D. Every time this instruction executes, it energizes the output only once.
When the contact, M0.1, is powered ON (1), the instruction inverts the bits in the DWORD data register, D15, and saves the result in the data register, D18.
