The IAP Device resource is a collection of objects in the request and feedback channels. Each set of IAP device objects represents one physical device and its interface with data points, properties and so on. This example going to perform various operations on DIO device. The example explains the essential operations for DIO device as listed below.

  1. DIO device creation [Request and Response]
  2. DIO device provision [Request and Response]
  3. DIO device send data for relay on interface 1 [Request]
  4. IOX sends response on feedback channel for relay data on the same interface to Apollo. [Response]
  5. DIO device deprovision [Request and Response]

DIO Device Creation

The topic for creating DIO device will be glp/0/SID/rq/dev/IOX_HANDLE/dio/do and the action object from the message should be create .

Request

DIO Device Creation
glp/0/1401/rq/dev/iox.409eb1/dio/do {
"action":"create",
"args": {
"type":"dio",
"unid":"256"
}
}


This will create the DIO device and publishes its status and configuration objects on the feedback channel also leaves the device in the unprovisioned state.

Response

Create DIO Device will respond on the feedback channel and there corresponding status and configuration message publishes on the below topic:

 glp/0/SID/fb/dev/IOX_HANDLE/dio/cfg  and  glp/0/SID/fb/dev/IOX_HANDLE/dio/sts
