DMC developed two programs for wastewater plants, working with a client who sells touch panels to waste water treatment facilities. These panels regulated customer access to the wastewater facility and tracked facility usage for billing purposes. The first of the programs developed by DMC communicated with a PLC, managed customer accounts, and transferred account usage and other information from the PLC to a Microsoft Access database file. The second program allowed for report generation based on information in the database, also allowing accounts to be added and managed and prices to be set.
