The frame contains no message header byte, nor end of message bytes. It is defined as follows:The data is transmitted in bi

45、nary code. CRC16: cyclical redundancy check.The end of the frame is detected on a silence greater than or equal to 3 characters.PrincipleThe Modbus protocol is a master-slave protocol.MasterOnly one device can transmit on the line at any time.The master manages the exchanges and only it can take the

46、 initiative.It interrogates each of the slaves in succession.No slave can send a message unless it is invited to do so. The master repeats the question when there is an incorrect exchange, and declares the interrogated slave absent if no response is received within a given time period.If a slave doe

47、s not understand a message, ids anexception response to the master. The master may or may not repeat the request.Slave iSlave j Slave k Direct slave-to-slave communications are not poss ble.For slave-to-slave communication, the application software must therefore be designed to interrogate a slave a

48、nd send back data received to the other slave.Two types of dialogue are possible between master and slaves: the master sends a request to a slave and waits for its response the master sends a request to all slaves without waiting for a response (broadcasting principle)Addresses The drive Modbus addr
