| Abstract | CANopen is a field level communication protocol for industrial automation distributed applications. CANopen offers a powerful set of higher level application layer services which implement an object-oriented distributed environment for simplified system integration. Often, sensors and actuators have to be placed at geographically remote locations, at considerable distances from the processor(s) running a control application. When this is the case, a possible solution is to use an autonomous I/O module, located close to the sensors and actuators, that provides the application with an interface to these devices. The application must be distributed between the remote I/O module and the local processor(s) using a communication network to allow the different parts to cooperate. This work is centred on the development of an I/O module based on the SAB-C167CR-LM chip from SIEMENS. The I/O module makes sensors and actuators accessible via the CAN bus, using the CANopen protocol. The objective is to show that CANopen can be implemented over new hardware platforms, in minimum time, with satisfactory results. It is shown that CANopen provides a systems-integrator-friendly object-oriented environment and that for this reason, the CANopen Communication Profile greatly simplifies the implementation of distributed applications in CAN based systems. Furthermore, CANopen also provides flexible real-time data transfer mechanisms that are able to meet time-critical constraints and, therefore, make CANopen a good solution for distributed control environments. |

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.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
