초록 ▼

A transfer network interface module provides a communication link between a data communications network bus connecting a plurality of processor based devices and a redundant processing system. The redundant processor system has first and second processor based devices communicatively coupled to at least one other remote based device by means of the data communication network. The first processor based device operates on an active status and the second processor based device operates on a backup status until a switch occurs. The switch causes the second processor based device to begin operation on active status. The transfer network interface device is communicatively disposed between the first and second processor based devices and the data communications network and permits continuous communication between either of the first and second processor based devices and the remote processor based device regardless of which of the first and second processor based devices is on active status. Each transfer network interface module has a thumbmwheel switch for setting a unique address and a mutually common address on the data communications network.

대표청구항 ▼

For a redundant processor system having first and second processor based devices, the redundant processor system communicatively coupled to at least one other remote processor based device by means of a data communication network, said data communication network conveying blocks of data to designated addresses, wherein said first processor based device operates on active status and said second processor based device operates on backup status until a switch occurs, said switch using said second processor based device to operate on active satus, a transfer network interface device for permitting continuous communication between either of said first and second processor based devices and said remote processor based device, the transfer network interface device comprising: (a) first and second transfer network interface modules, each communicatively coupled between a respective one of said first and second processor based devices and the data communication network for transferring data between said respective fist and second processor based device and said data communication network, wherein each of said first and second transfer network interface modules has a thumbwheel switch for setting both of a unique address and a mutually common address on the data communication network; (b) said first transfer network interface module including means continuously responsive to data blocks addressed to its unique address, and responsive to data blocks addressed to its common address when said first processor based device is active; and (c) said second transfer network interface module including means continuously responsive to data blocks addressed to its unique address, and responsive to data blocks addressed to its common address when said second processor based device is active.
