Although there are coding guidelines for many programming languages, these are nearly non-existent for the important area of industrial control, e.g. IEC 61131-3 and its PLCopen extensions.
Nevertheless, the software in the industrial environments becomes more and more important, the software projects become larger, and the costs of errors increase. Software nowadays absorbs half of the initial project costs and between 40 and 80% deals with maintenance over the life cycle costs of the software.
In order to deal with the complexity of larger programs one needs modern software development processes supporting a structured approach. Also, we need to increase
