Abstract—Network protocols today play a major role in embedded
software for industrial automation, with constant efforts
to adapt existing device software to new emerging standards. In
earlier work, we have proposed a compilation-based approach
using a domain-specific language, Protege, which automatically
generates protocol stack implementations in C from modular
high-level descriptions. In this paper, we provide a case study
of the Protege language in an industrial setting. We have implemented
the Modbus protocol over TCP/IP and over serial line,
and tested it using an industrial gateway. Our implementation
demonstrates Protege’s advantages for software productivity, easy
maintenance and code reuse, and it achieves many desirable
properties of industrial embedded network software.
