Abstract:

Open all-digital communications protocol FOUNDATIONTM Fieldbus offers a wide range of benefits to

process control systems through data reliability, diagnostics, interoperability, and distribution of

controls to an unprecedented level. However, lack of media redundancy on its H1 networks can

compromise the availability of view and control of a critical process. In this thesis a novel approach is

proposed to add fault tolerance by achieving media redundancy on H1 networks. It presents an H1

topology framework capable of detecting and handling break in the network to allow control and

communication to continue uninterrupted. Test network with a functional prototype is constructed to

evaluate real world control application in fully redundant settings. Results show that continuity of

control and supervisory view to the process remain uninterrupted when cable break is induced,

resulting a fault tolerant H1 network.
