This paper provides details of an innovative solution that was utilized for Dallas
Water Utilities to overcome communication redundancy limitations. This solution,
developed through a multiple firm effort, includes a ring topology on a Modbus serial
network that allows Modbus command messages to be transferred to all devices on the
network ring in either a clockwise or counter-clockwise direction. An intriguing benefit
gained from this solution is that a cable break is readily identified as each device reports
the direction in which it is receiving commands. This paper presents a case study
detailing the initial criteria for the design, a discussion of the challenges in developing
this solution, and the advantages gained subsequent to its implementation. Includes table, figures.
