Sorry if I didn't explain myself well.
I am using a Conduit Multitech to create a LoRa net and control some devices.
The Conduit has internally the NodeRed and I am using it in order to send payloads to the Conduit and those payloads are saved in the downlink queue.
Now I am sending that payloads in two different ways:
- Injecting timestamps from the NodeRed interface (just pressing the timestamp button) and, as a consequence, activating the function I want.
- Through an external interface connected to the NodeRed via MQTT which also activate those functions.
What I want to do is to send that payloads (just to activate the function I am activating now through the timestampt button or the external interface) but using my PLC instead.
Then my question is what blocks/commands I should use in order to recognize from NodeRed that I'm sending that payloads from the PLC (it has the protocols I told you in the previous message)
Thank you very much for your responses,
