Page 150 Chapter 8 Modbus Communication Chapter 8 Modbus Communication 8.1 General Modbus protocol is specified open protocol used between client-server, which executes reading/writing data according to function code. Communication between devices that use Modbus protocol uses Client-server function in which only one client processes the data.
Page 151 Chapter 8 Modbus Communication 8.2.2 Structure of modbus protocol Modbus protocol’s structure is as follows. In case of normal communication, process step is as follows. In case of abnormal communication, process step is as follows. When receiving the abnormal frame from client, server transmits error code and exceptional code. Error code is function code adding 80(Hex) and exceptional code indicate the specific error content.

Page 267 Appendix Appendix A. 1 Definition of Terms (1) Communication type (a) Simplex This is the communication type that data is transferred in a constant direction. Information can not be transferred in the reverse direction. (b) Half-Duplex Data is transferred in two ways with one cable if time interval provided, though it can’t be transferred simultaneously. (c) Full-Duplex Data is simultaneously transferred and received in two ways with two cables.
Page 268 Appendix (b) Parallel transmission This type is used in printer, etc., which transmits data in unit of 1 byte, so the speed is high and the accuracy of data is reliable. However, the longer the transmission distance is, the higher the cost of installation is geometrically. 송신...
Page 269 Appendix (4) Protocol This is communication rule established in relation between the transmission side and the receiving side of information in order to send and accept information between two computers/terminals or more without error, effectively, and reliably. In general, this specifies call establishment, connection, structure of message exchange form, re-transmission of error message, procedure of line inversion, and character synchronization between terminals, etc.
Page 270 Appendix (11) Half Duplex Communication Two-way communication is available, however simultaneous communication of transmission & receiving isn’t available. This communication type is applied to RS-485 for instance. It is used a lot for multi-drop communication type which communicates via one signal line by several stations. Half Duplex Communication results from the transmission characteristic performed by stations one by one not allowing simultaneous transmission by multi stations due to the data damage of data impact caused by the simultaneous multi-transmission of the stations.
Page 271 Appendix (13) BCC(Block Check Character) As serial transmission may have signals distorted due to undesirable noise in transmission line, BCC is used as data to help receiving side to check the signals if normal or distorted and to detect errors in signals as compared with the received BCC after calculating BCC by receiving side itself using the data input to the front terminal of BCC.
