Modular overload relay assembly with a modular communication and human interface module
摘要
Methods and systems for communicating information from a first modular electronic device to a second modular electronic device. The first modular electronic device transmitting a first serial data frame over a two-wire communication protocol. The first serial data frame containing status information, a heartbeat challenge and a frame check character. The second modular electronic device able to receive the first serial data frame, validate the data and display status information on a local human interface. The second electronic device able to respond to the first electronic device by transmitting a second serial data frame. The second serial data frame containing a heartbeat response and a frame check character response. The first modular electronic device having the ability to place a modular electronic overload system in a safe state if communication is lost between the first modular electronic device and the second modular electronic device.
