  • Page 15: Planning For A Parallel Port

    ControlNet System Overview Communication between either a parallel or serial host and the KFC15/KFCD15 module is carried out using Allen-Bradley’s proprietary DF1 protocol. DF1 is a full- or half-duplex protocol that carries messages intact over a link. The protocol delimits messages, detects and signals errors, retries after errors, and controls message flow.

  • Page 16: Planning For An Rs 232C Serial Port

    ControlNet System Overview 1–5 When connection is via the parallel port you can have only one KFC15/KFCD15 module per host. The maximum recommended cable length between the KFC15/KFCD15 module and the parallel host is 3 m (10 ft). The cable between the KFC15/KFCD15 module and the parallel host must be shielded.
