5.2.6 Communication DB Elements

5.2.6.1 AF100 BUS Communication

To send and receive data on the AF100 network, DSPs are used. A DSP can hold one to eight DATvalues.

5.2.6.2 DSPs

This section describes how DSPs are used and the naming conventions. Standard signal namingconventions are documented in 00000-ICE-3889, "Coding Standards and Guidelines for Common QSystems" (Reference 4) and subsection 2.3.1 of WNA-SD-00239-WBT-P, "Watts Bar 2 NSSSCompletion Program I&C Projects Software Requirements Specification for the Post AccidentMonitoring System" (Reference 7).

5.2.6.2.1 DSP Terminal Settings

Standard DSP configuration requirements and guidelines used in the PAMS station or processor areidentified in Section 4 of WNA-SD-00239-WBT-P, "Watts Bar 2 NSSS Completion Program I&CProjects Software Requirements Specification for the Post Accident Monitoring System" (Reference 7).
