Modbus RTU is an open, serial (RS 232 or RS 485) protocol derived from the Master Slave architecture. It is a widely accepted protocol due to its ease of use and reliability. RS485 & Modbus Protocol Guide Te Connectivity In the MODBUS protocol the master can address individual slaves, or, using a special “Broadcast” address, can initiate a broadcast message to all slaves. The SPR and Integra products do not support the broadcast address. MODBUS Message Format The MODBUS protocol defines the format for the master’s query and the slave’s response. cb1241 wiring for modbus rtu Entries Forum Industry ...
