  • Page 20: Serial Transmission Of A Character

    Basic Principles of Serial Data Transmission Serial Transmission of a Character There are various networking alternatives for the transfer of data between two or more communication partners. The simplest form of data interchange is via a point-to-point connection between two communication partners. Point-to-Point Connection In a point-to-point connection the CP 440 communication processor forms the interface between a programmable controller and a communication partner.
  • Page 21 Basic Principles of Serial Data Transmission Bidirectional Data Traffic - Operating Modes The CP 440 has two operating modes for bidirectional data traffic: Half-duplex operation (3964(R) procedure, ASCII driver) Data is exchanged between the communication partners but only in one direction at a time.
  • Page 22 Basic Principles of Serial Data Transmission Character Frames Data is transmitted between the CP 440 and a communication partner via the serial interface in a character frame. Two data formats are available for each character frame. 7 data bits without a parity bit are not supported. You can parameterize the format for data transmission with the CP 440: Point-to-Point Communication, Parameter Assignment parameterization interface.

  • Page 24: Trdatansmission Procedure With Data Point-To-Point Connection

    Basic Principles of Serial Data Transmission Transmission Procedure with a Point-to-Point Connection When data is transmitted, all communication partners involved must follow fixed rules for handling and implementing the data traffic. The ISO has defined a 7-layer model, which is recognized as the basis for a worldwide standardization of transmission protocols for computer-to-computer communication.
  • Page 25 Basic Principles of Serial Data Transmission ISO 7-Layer Reference Model The reference model defines the external behavior of the communication partners. Each protocol layer, except for the lowest one, is embedded in the next one down. The individual layers are as follows: 1.
  • Page 26 Basic Principles of Serial Data Transmission Transmission Integrity Transmission integrity plays an important role in the transmission of data and in selection of the transmission procedure. Generally speaking, the more layers of the reference model are applied, the greater the transmission integrity. Classifying the Supplied Protocols The CP 440 can handle the following protocols: ASCII driver...
  • Page 27 Basic Principles of Serial Data Transmission Transmission Integrity with the ASCII Driver Data Integrity When Using the ASCII Driver: When data is transmitted by means of the ASCII driver, there are no measures to ensure data integrity other than the use of a parity bit (which can also be canceled, depending on how the character frame is set).
  • Page 28 Basic Principles of Serial Data Transmission Performance Limits with 3964(R) Performance Limits of the 3964(R) Procedure: Further processing of the send/receive data by the PLC program in the communication partner is not guaranteed. You can only ensure this by using a programmable acknowledgment mechanism.

  • Page 29: Data Transmission With The Ascii Driver

    Basic Principles of Serial Data Transmission 2.2.2 Data Transmission with the ASCII Driver The ASCII driver controls data transmission via a point-to-point connection between the CP 440 and a communication partner. This driver contains the physical layer (layer 1 of the ISO reference model.) The structure of the message frames is left open through the S7 user passing on the complete send message frame to the CP 440.
  • Page 30 Basic Principles of Serial Data Transmission Sending Data with the ASCII Driver When you send data, you specify the number of user data bytes to be transferred in the “LEN” parameter of the call of the SEND_440 function block. When you work with the end criterion “character delay time expired” when receiving data, the ASCII driver pauses between two message frames when sending.

  • Page 33 Basic Principles of Serial Data Transmission End Criterion: “Expiration of Character Delay Time” When data is received, the end of the message frame is detected when the character delay time expires. The received data is accepted from the CPU. In this case, the character delay time must be set such that it reliably expires between two consecutive message frames.
  • Page 34 Basic Principles of Serial Data Transmission End Criterion: End-of-Text Character When data is received, the end of the message frame is detected when the parameterized end-of-text character(s) arrive. The following options are available: One end-of-text character Two end-of-text characters, 1st and 2nd end-of-text characters Two end-of-text characters, 1st or 2nd end-of-text character The received data including the end-of-text character(s) is accepted from the CPU.

  • Page 39 Basic Principles of Serial Data Transmission Data Flow Control/Handshaking Handshaking controls the data flow between two communication partners. Handshaking ensures that data is not lost in transmissions between devices that work at different speeds. Software handshaking is supported with XON/XOFF in the CP 440.

    Basic Principles of Serial Data Transmission Note When you run the ASCII driver in RS422 multipoint or RS485 mode, you must take steps in the user program to ensure that only one node sends data at any one time. If two nodes send data simultaneously, the message frame is corrupted. 2.2.3 Data Transmission with the 3964(R) Procedure The 3964(R) procedure controls data transmission via a point-to-point connection...
  • Page 43 Basic Principles of Serial Data Transmission Priority With the 3964(R) procedure, one communication partner must be assigned a higher priority and the other partner a lower priority. If both partners begin connection setup at the same time, the partner with the lower priority will defer its send job.
