  • Page 29: Message Exchange

    Message Exchange What is a message Your computer communicates with the UDC controllers using the exchange? RS422/485 link. Each communication takes place as a message exchange: Your computer sends a request message (ASCII characters), and then waits for the resulting response from the controller involved (ASCII characters).

  • Page 30: Request Messages

    Request Messages What is a request Your computer queries a controller and indicates the communication message? function, or operation, that the controller should perform by sending a request message. Request messages are composed of standard fields, separated by commas. Each field contains a certain kind of information, which you must enter in order to have a valid request message.

  • Page 43: Shed

    Shed What is Shed? Shed happens when the controller, which has been working in "Slave," reverts to "Stand Alone" mode. Upon receiving a "Slave" message, the controller resets the "SHED TIMER." If this timer expires before the next valid message, the controller goes to stand alone operation. When the host reconnects with a valid message, the response will indicate as 8 at the third digit to indicate a restart after shed.
