| Abstract | The aim of the paper is to evaluate the impact of the occurrence of faults on the IEC 61158 type 1 field-bus protocol. This communication system was developed for use in a process control environment, where robustness to the occurrence of a fault is an important requirement. After a survey of the protocol's main features, certain types of failures are defined, the occurrence of which may be critical for the communication system. It is shown that for some of the failures considered, the IEC 61158 type 1 protocol doesn't foresee any recovery procedure. When other failures occur, the fault states caused by them, may be not recovered by the fault recovery procedures provided for by the IEC 61158 type 1 standard. In particular it is shown that the standard provides for procedures aimed to recover faults caused by some kind of failure, but these procedures are unable to perform their goal. The evaluation of the effect of these faults on the performance of the communication system seems to be an important issue. For this reason, the paper presents a performance evaluation of the fault recovery mechanisms, foreseen by the IEC protocol, but unable to recover some faults. The evaluation is based on Petri Net model simulation, and is aimed at evaluating the impact on the recovery procedures on the information flow between control processes. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
