Fact #1 : Industrial IoT is one of the biggest slice of the global IoT pie.
Fact #2 : Zigbee is a popular industrial communication wireless standard
Fact #3 : Modbus is an indispensable part of industrial automation.
Our technical team realized this opportunity and came up with this Zigbee to Modbus TCP/IP gateway, that can act as an interface between a industrial Zigbee network and a Modbus TCP/IP or even a general TCP/IP network and hence the internet at large.
Naturally, when it came to selecting a Zigbee module we decided to go with the Telegesis ETRX357-LRS module, for a host of reasons. For the TCP/IP end we used the Xpico module by Lantronix. Because the Xpico comes in a general TCP/IP stack version and also a Industrial Modbus TCP/IP stack version.
To make the product more versatile we decided to add a ARM Cortex M4 MCU for some custom firmware and device management. To make the product truly easy to use and deploy on field we added a PoE+ (IEEE 802.3at) power option.
Look forward to comments and suggestions from experts here on potential use cases and opportunities with the product.
