    5. Modbus Protocol This chapter describes the Modbus protocol. In this chapter the host computer and SC-F71 are referred to as master and slave respectively. The master controls communication between master and slave. A typical message consists of a request (query message) sent from the master followed by an answer (response message) from the slave.
