S5 to S7 Output Address Mapping: A → Q (EN) / A (DE)
S5 to S7 output address conversion. Addresses identical — only English mnemonic changes: A (Ausgang) becomes Q (Output).
S5 to S7 Output Address Mapping: A → Q (EN) / A (DE)
Output addresses transfer directly. Address numbers are identical. Only the English mnemonic changes: A (Ausgang) becomes Q (Output).
Address Mapping Table
| S5 AWL | S7 STL (DE) | S7 STL (EN) | Description |
|---|---|---|---|
| A 4.0 | A 4.0 | Q 4.0 | Output bit 4.0 |
| A 4.7 | A 4.7 | Q 4.7 | Output bit 4.7 |
| AB 4 | AB 4 | QB 4 | Output byte 4 |
| AW 4 | AW 4 | QW 4 | Output word 4 (bytes 4+5) |
| AD 4 | AD 4 | QD 4 | Output double word 4 |
Key Facts
- 1:1 mapping. No address conversion needed.
- Peripheral outputs: PAW (Peripherie-Ausgangswort) remains PAW (DE) / PQW (EN) in S7.
- Output addresses typically start at byte 4 in S5 systems (0–3 reserved for inputs on many configurations). This is hardware-dependent and may change with S7-1500 hardware configuration.
