17. 3 5 characters Principle The Modbus protocol is a master slave protocol Only one device can transmit on the line at any time The master manages the exchanges and only it can take the initiative It interrogates each of the slaves in succession Master No slave can send a message unless it is invited to do so E9 In the event of an error during data exchange the master repeats the question and declares the interrogated slave absent if no response is received within a given time period J a If a slave does not understand a message it sends an exception response to the master The master may or may not repeat the request Direct slave to slave communications are not possible For slave to slave communication the application software must therefore be designed to interrogate one slave and send back data received to the other slave Two types of dialog are possible between master and slaves e The master sends a request to a slave and waits for it to respond The master sends a request to all slaves without waiting for them to respond broadcasting principle 28 Modbus protocol Altivar 71 Integrated Modbus The Altivar 71 features 2 integrated Modbus ports Modbus network Modbus HMI These 2 ports are physically independent of one another They are connected to 2 different Modbus networks each with its own master Different speeds and formats are possible in each case
