Driver Matrix¶
| Driver | Use it for | Best first doc |
|---|---|---|
simulated |
deterministic fake process I/O without hardware | Simulated And Loopback |
loopback |
fast %Q -> %I local sanity checks |
Simulated And Loopback |
gpio |
local edge/device pin mapping | GPIO |
ethercat |
deterministic fieldbus I/O | EtherCAT |
modbus-tcp |
register-mapped external systems | Modbus TCP |
mqtt |
broker-backed event/message exchange | MQTT |
| multi-driver | one runtime using more than one driver family | Multi Driver |
Selection rule¶
- Start with
loopbackorsimulatedwhen you are still proving logic. - Move to
gpioorethercatfor local hardware. - Move to
modbus-tcpormqttfor external-system integration. - Use multi-driver only after each individual driver validates cleanly by itself.
