NBIM01 | ABB Bailey Bus Interface Module

Network 90 Bus Interface ModuleThe Loop and Bus Interface Modules (LIM/BIM) provide the principal communication interface between INFI 90 Process Control Units and Plant Loop. Plant Loop is a high speed (500 kbaud) serial communication highway that all INFI 90 modules share. A maximum of 63 nodes, in any combination, can be on the Loop.The Loop and Bus Interface Modules (LIM/BIM) provide the principal communication interface between INFI 90 Process Control Units (PCU) and Plant Loop. Plant Loop is a high speed (500 kbaud) serial communication highway that all INFI 90 modules share. A maximum of 63 nodes, in any combination, can be on the loop. The INLIM03 and INBIM02 are directly upward compatible with Network 90 NLIM02 and NBIM02..The modular design of the LIM and BIM modules, as with all INFI 90 modules, allows for flexibility when creating a process management system strategy. An optional second LIM/BIM pair can be added to provide a redundancy feature to the system. One pair performs the primary interface function, while the other LIM/BIM pair is on standby. Should a primary failure occur, the secondary pair comes on-line without interrupting the process. Other features include selectable poll rates (the time between module output block checks), on-board diagnostics, and 32 kbytes of RAM available to the BIM user. Each LIM provides redundant loop interface and the physical media is redundant
