    Chapter 12 Installation and Wiring 12.4 Channel Operation during Normal Run In case of built-in Cnet, each communication port operates independently to allow simultaneous Tx/Rx in separate transmission specifications. In case of XBL-C21A/C41A, only one channel is available. In case of built-in Cnet, transmission specifications can be set per RS-232C and RS-422 channel, and the operation is started and stopped according to channels.

    Chapter 12 Installation and Wiring 12.6 Cable Specifications (1) When using communication channel, RS-422 or RS-485, twisted pair cable for RS-422 shall be used in consideration of communication distance and speed. (2) [Table 12.6.1] describes recommended specifications of cable. Also when using other cable than recommended, the cable conforming to characteristics in [Table 12.6.1] shall be used.

  • Page 177: Appendix 1.2 Serial Communication Terms

    Appendix 1 Definition of Terms Appendix 1.2 Serial Communication Terms Describes serial communication term (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.
  • Page 178 Appendix 1 Definition of Terms (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.
  • Page 179 Appendix 1 Definition of Terms (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 180 Appendix 1 Definition of Terms (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 181 Appendix 1 Definition of Terms (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.
  • Page 182 Appendix 1 Definition of Terms (15) Frame Frame is composed of transmitted and received data as in a specified form in data communication including additional information of segments [station No., command, parameter by command], control characters [ENQ, ACK, EOT, ETX] for synchronization, parity for detecting error, and BCC. The structure of frame used for serial communication of Cnet is as follows.
