WebOverview. The Modbus protocol exchanges information using a request-reply mechanism between a master (client) and a slave (server). The master-slave principle is a model for a communication protocol in which one device (the master) controls one or more other devices (the slaves). In a standard Modbus network, there is 1 master and up to 31 slaves. WebModbus is a serial communication protocol developed by Modicon, published by Modicon® in 1979, for use with programmable logic controllers (PLC). In simple words, it is a method for transmitting information over serial lines between electronic devices.

Implementing Modbus and CAN Bus Protocol Conversion Interface

WebThe LoRa Modbus receiver can handle ¬† up to¬†40 transmitters. The transmitter information is stored in the receiver Modbus table. The PLC can then read the registers of the receiver to retrieve the data. It is also possible to write to the Modbus table of the receiver to re-configure already installed transmitters and add new ones. WebTransmissions must be contiguous which limits the types of remote communications devices to those that can buffer data to avoid gaps in the transmission.
