**I am sending back the exact same request json with additional variables of successCode in case of success and errorcode in case of error.**  **I have added sample response json in function node**

Good - ok. I understand that.

**1. After getting the request json I am updating the sensor through TCP protocol. I will have predefined tcp nodes and based on sensor id , I will send response to tcp server.**  
**2. I will be sending opValue to tcp server based on sensorId. all parts are relevant and need to send back same request json with success code.**  
**3. opValue**  
**4. Multiple sensor can have same server or multiple. It depends but currently as first step I am trying to update the same tcp server.**

**TCP server may or maynot send the response. If Server update is successful and I dont get any error, I need the send the same request json with additional parameters succiessCode and ErrorCode in paramList.**

```auto
**Response JSON**
 **{**
**"sensorList": [**
 **{**
 **"sensorId": "6131a8d409e2162ea1df532e",**
 **"protocol": "tcp",**
**"paramList": [**
 **{**
 **"paramName": "voltage",**
 **"opValue": "220",**
 **"successCode": "",**
 **"errorCode": ""**
 **}**
**]**
 **},**
 **{**
 **"sensorId": "6131a8d409e2162ea1d423432e",**
 **"protocol": "tcp",**
**"paramList": [**
 **{**
 **"paramName": "temp",**
 **"opValue": "220",**
 **"successCode": "",**
 **"errorCode": ""**
 **}**
**]**
 **}**
**]**
 **}**

```
