I am a reporter for a newspaper in New Mexico examining public access to public data held by a small public water utility. The software manufacturer tells me data is stored in POCs as likely Modbus data, and hence would be public data under our state's public records laws.
The software configuration in this system does not provide an easy means for porting a public view of well activity or tank levels separate from secure areas of the Web accessible SCADA system controls. Generally, the company that wrote developed the SCADA system has never been asked to develop a public view, and a sales rep says it could cost thousands to develop such access.
For the sake of discussion, let's presume the public has a right, need and desire to know how much water is in the system at any moment. Can anyone cite a system where public access to water system data has been provided in a SCADA system, or a circumstance where the concept has been considered and rejected?
