LV434107 09 2009 19 Modbus Protocol Modbus Master Slave Principle Overview 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 are 1 master and up to 31 slaves A detailed description of the Modbus protocol is available at www modbus org Characteristics of the Master Slave Principle The master slave principle is characterized as follows Only 1 master is connected to the network at a time Only the master can initiate communication and send requests to the slaves The master can address each slave individually using its specific address or all slaves simultaneously using address 0 The slaves can only send replies to the master The slaves cannot initiate communication either to the master or to other slaves Master Slave Communication Modes The Modbus protocol can exchange information using 2 communication modes Request Reply Mode request reply mode broadcast mode In request reply mode the master addresses a slave using the specific address of the slave The slave processes the request then replies to the master 1 2 3 Slave 1 Slave 2 Slave n Request Process Reply
