This document describes the operation and interface definition of the Panoramic Power bridge when working in the stand-alone mode. In this mode, the bridge implements a Modbus TCP protocol which sends sensor's current readings to a local server. The local server acts as a Modbus master server and the bridge acts as a Modbus TCP slave. This guide focuses on the new bridge stand-alone (Modbus TCP) operational mode. It is supplementary to the Gen 4 Bridge User Guide which covers basic bridge operations and should be reviewed prior to using this guide. We hope this guide is helpful to you. If you have any questions, please feel free to contact us.
