To administrate devices through a web interface is simple, fast and comfortable. Also can be added, that it´s a solution that saves time and money and in a vast majority of cases it´s beneficial for a producer and also a customer. Besides common “network devices” for example for data acquisition (telemetry – when we want a device to send measured data), a network connectivity is still more used at devices, whose functionality is not dependent on a web connection. Usually here belong devices, where this “extra functionality” brings several advantages.
Example of such device can be for example a heating boiler, where a user can comfortably monitor its operation and change temperature and in case of a required service a producer can diagnostic the device remotely – without a costly personal inspection.
Novelty in this field is the WIZ550WEB module based on the W5500 chip (10/100 Mbps) from company Wiznet and the STM32F103RBT6 MCU. Hardwired core is highly stable and resistant to attacks. By means of the WIZ550WEB module you can use 16 digital I/O pins and 4 analogue inputs. It also supports serial configuration via AT commands.
The simplest way to start is to use a rich-featured development board Wiz550WEB-EVB with 8 output relays, 8 digital inputs with optocouplers (TLP290-4) and 4 analogue inputs (0-12V).
