Address Syntax
Delta uses specific device codes. Note that input/output addressing is often in Octal.
| Area | Prefix | Description | Example |
|---|---|---|---|
| Data Register | D | 16-bit Word | D100, D0 |
| Internal Relay | M | Bit | M100, M0 |
| Input | X | Input (Octal) | X0, X7, X10 |
| Output | Y | Output (Octal) | Y0, Y7, Y10 |
| Timer | T | Timer Value | T100 |
| Counter | C | Counter Value | C100 |
For X and Y devices, the address jumps from 7 to 10 (e.g., X0...X7, then X10). Proxus handles this automatically if you use the correct string syntax.
