**Writes to M / Q are real** — they drive the PLC program. Be careful what you
flip on a running machine.
### Hardened CPU — forcing OP-class TSAP
```powershell
# Probe a hardened S7-1500 that rejects PG class but accepts OP.
otopcua-s7-cli probe -h 10.50.12.30 --tsap-mode Op
# Read against the same CPU.
otopcua-s7-cli read -h 10.50.12.30 --tsap-mode Op -a DB1.DBW0 -t Int16
# Manual TSAP override (e.g. site with a fixed proprietary TSAP gateway).
otopcua-s7-cli probe -h 10.50.12.30 --tsap-mode Other --local-tsap 0x4D57 --remote-tsap 0x4D58
```
Without `--tsap-mode`, the CLI uses S7netplus's CpuType-derived default (PG
class for almost everything). The same connection-refused failure shape that a
wrong `--slot` produces also shows up when the CPU rejects PG class — try
`--tsap-mode Op` first when the handshake is failing on otherwise-correct
endpoint config. See [s7.md TSAP / Connection Type](v2/s7.md#tsap--connection-type)
for the byte table and motivation.
