The National Instruments Fieldbus Round Card is a stand-alone card that allows you to interface to a network that complies with the Fieldbus Foundation H1 specification. The Fieldbus Round Card is powered from the Fieldbus. The Fieldbus Round Card uses the Motorola MC68331 embedded processor and a programmable 128 KB X 16 Flash to run the Stack Interface Library, Function Block Shell, and user applications. A 128KBX 16 SRAM device on the card provides volatile memory. The Fieldbus Round Card also has a 8 KB X 8 Serial ROM (SROM) that serves as non-volatile memory. This non-volatile memory is used to store the Fieldbus MIB parameters and block parameters.
