| Abstract | Programmable logic controllers (PLCs) are the universally accepted automation components in industrial control. IEC61131–3 standard was developed to unify textual and graphical ways of describing the control specification for PLCs; ladder diagram being one such control specifications. However, PLCs available in the market as on today are vendor specific and replacement of PLC of one vendor in a process equipment by PLC of another vendor is not possible due to lack of standardization among EDA tools from PLC vendors. Secondly, heart of PLCs is a sequential processor which cannot execute parallel rungs of ladder diagram concurrently. Perhaps this aspect did not pose any problem so far due to large response times associated with industrial processes. However with introduction of high speed MEMS sensors along with increased control complexity, the need for high speed PLCs has been spelt out. Further, the safety features of control system are now expected to be integral part of ladder control specification. Field Programmable Gate Arrays (FPGAs) have better portability support, ability to support implementation of concurrent logic and security aspects. They have been mentioned in the literature as prospective programmable devices to implement control logic of PLCs. However, utilization of FPGAs for implementing control specification demands development of integrated environment to convert ladder logic as per IEC61131–3 to HDL. This HDL specification further can be ported to any of the standard FPGA development environments. It is seen through literature that not enough efforts have been focused on developing such integrated environment. This paper focuses on the details of such environment being developed by authors to convert IEC-61131–3 control specification standard to VHDL for direct synthesis. |

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.
