# TCP

The user supported by OneNET upload data through TCP transparent, which provides feasibility for any protocol device to access OneNET. The device accesses OneNET through TCP connection. The data can be interacted with OneNET after authentication. OneNET can parse uploaded data and send data to device through user-uploaded self-defined scripts.

Functions and Characteristic

  • Long connectivity
  • User-defined scripts, only support lua
  • High flexibility
  • Support one connection to transmit multiple device data

Usage Restrictions

Restricted Items Restricted Content Overrun Description
Number of scripts in product Up to 10
Script file size less than 2M
Single script running memory less than 100kB discard data when overrun
Script single execution time less than 2ms discard data when timeout
flow limit device data, uplink/downlink data message length no more than 1k discarded data when overrun

Typical Application Scenarios

High flexibility of TCP transparent determines that it is unconstrained. It is mainly applicable to user-defined protocol. It can interact with any protocol according to scripts defined by itself, and supports scripts to be modified and uploaded at any time. The protocol supports one connection to transmit multiple device data, and can centrally connect multiple devices to upload and download data. It is widely used in intelligent instruments such as intelligent meters and water meters.
