Abstract:
The IEC61131-3 standardized five PLC programming languages and presents a software model that stimulates practices such as code reuse. The adoption of this standard in the modernization of the Brazilian Navy mine-sweepers allowed the development of a reliable software, easy to test and maintain, with high productivity. Although the PLC used in this project did not provide natively all the languages proposed by IEC, this paper describes tools and methodologies developed to overcome this deficiency.
