Abstract
In this work, a Power over Ethernet device was designed with characteristics that makes it industrial grade capable. A DIN rail 3D enclosure was designed for completeness of the hardware. A new software module was developed for an existing SCADA open source solution, the software module allows the discovery and configuration of the device. The solution was tested using the modbus industrial protocol on a simulator and also on an industrial energy meter to finally highlight its configuration process and real usage.
Introduction
The WIZ750SR device is a complete solution for Ethernet to Serial devices, including even options for RS-232 and RS-485 levels. The device has an embedded firmware that allows configuration using an open source software developed by WIZnet which makes it easy for prototyping and testing. Nonetheless, the device itself needs some extra hardware to be able to effectively be used in a commercial product, different factors such as serial connectors, power supply and even a stable fixture for enclosure design are needed in order to be ready for the market. Commercial market is even different from Industrial or Electrical sector, mainly because different standards need to be meet for product acceptance but not always a product that meets with hardware standard break the barrier of acceptance, there is also a factor that plays an important role, the term to consider is Integration. An easy integration makes the product more prone to be adopted.
All these factors have been taken into consideration in this work to present a solution that meets hardware standards for the Industrial market and makes easier the work of field engineers by integrating a configuration interface in a well known open source SCADA software. Complete instructions for Integrator persons are provided but also developing details are explained.
