Abstract

The DTI/SERC sponsored collaborative project1 entitled Software Engineering Methods for Safe Programmable Logic Controllers (SEMSPLC) has produced a Code of Practice for developing safe PLC application software. The Code of Practice is based on the joint experience of both the software engineering community and the PLC industry. Currently the project is applying the Code of Practice on demonstrator projects. This paper introduces the Code of Practice and examines the early results of its application.
