The Fife SBPC-21-EN/IP (Serial Bus Protocol Converter) provides a gateway between Fife’s
proprietary FifeNet network and an Ethernet network. The SBPC-21-EN/IP uses the standard RJ-45
connector and conforms to EtherNet/IP Level 2 I/O Server CIP Protocol. As shown in the diagram
below, the SBPC-21-EN/IP connects to both FifeNet and Ethernet/IP.

Producer/Consumer Model
The Producer/Consumer Model allows the exchange of information between a sending device
(“producer”) and many receiving devices (“consumer”) without requiring the same date to be sent
multiple times to different destinations. The producer sends the data once and each consumer on the
network receives the data at the same time. The data can be used (consumed) or ignored by each
receiving device independently. FifeNet uses the Producer/Consumer Model.
FifeNet
FifeNet’s deployment of the Producer/Consumer Model allows data sent by a single device to be
received simultaneously by multiple devices on the same network. Each receiving device can choose
to use (consume) the information or ignore it as needs dictate. FifeNet is based on a fixed time slicing
architecture where transmitting devices send data in fixed, predetermined time intervals.
FifeNet
The SBPC-21-EN/IP
connects to both
FifeNet and Ethernet
providing translation
between the two
networks.
