Two Node-RED custom nodes:

  • Output 2: one or more discrete event messages
• triggerSubscriber
  • Subscribe by event name from the formatter's discrete output

iotDataFormater

Global config

• MDS
• Line ID
• Machine ID

Continuous tags

Each row has:

• enabled
• tag name
• source path/expression (example: payload.goodCount)
• type (raw, number, string, boolean)

Discrete rules

Each row has:

• enabled
• event name
• mode (Expr, Rising, Falling, Change, When True)
• source field or expression
• optional payload template

Notes:

• For Expr, source is a JavaScript expression like msg.payload.fault_code > 0
• For other modes, source is a field path like payload.fault
• A single input can emit multiple discrete events

triggerSubscriber

• Filters incoming discrete messages by event name
• Optional pass-through mode or compact output

Restart Node-RED after install.
