Getting Started With Tapioca
A Tapioca gateway is schematically made up of a TapNLink module, a transceiver and a voltage regulator for the power supply.
Depending on the transceivers, the different models of Tapioca can handle different types of links used in the industry: RS485, RS232, USB (device), CAN or Ethernet.
These three 'step by step' tutorials for Tapioca communications applies to all versions of the Tapiocas:
-
The Modbus Direct tutorial gets direct access to modbus registers from a mobile application (e.g. IoTize Toolbox).
-
The Modbus Variable tutorial defines modbus registers as monitorable variables within IoTize Studio. Modbus can access variables securely through the access control mechanism.
-
The Modbus Slave tutorial configures the Tapioca as a modbus slave device, with its own set of variables accessible as modbus registers.
To go further
- The Modbus demo is a project that runs a light modbus server on a computer and uses the Tapioca USB to monitor some information through a mobile application.
