Module of Digital Inputs with Modbus Communication
Nožka, Tomáš ; Štohl, Radek (referee) ; Bradáč, Zdeněk (advisor)
Bachelor’s thesis deals with the basic specification of Modbus protocol and its use for communication between the remote digital inputs device module and device that uses information obtained from remote inputs. The thesis proposal is to further describe hardware and software for the module. Processor i8051 series provides the function of the whole procedure. Unit acts as a slave device. Communication with the remote device is done via serial interface (RS-485 and RS-232) using one of two modes of communication either Modbus RTU or Modbus ASCII. Primarily information on the status of digital inputs are being provided to the remote devices. The work also includes information about some professional modules of inputs and outputs communicating via Modbus protocol.
