SCADA Systems

Preferred Controls has the expertise you need for your plant or telemetry based SCADA system. We have successfully deployed and added to a large number of SCADA systems throughout the country. These systems range in complexity from small single computer systems to large multi-server based systems. We have experience with practically every form of remote communications including telephone lines, fiber, radio, cellular, and satellite. Our experience with plant networks is equally impressive, it includes TCP, UDP, DeviceNet, ControlNet, Hart, DH+, DH485, and more.


We work with a variety of HMI software packages and programmable logic controllers. Our ability to look beyond a single technology allows us to succeed when others fail. The data analysis and reporting capabilities of our SCADA systems is second to none. Our powerful database, SQL query based reports provide an open, expandable, non-proprietary solution ideal for any reporting solution. We have always been at the forefront of remote access and alarming, We were deploying true text-to-speech software dialers and smart phone interfaces for our SCADA systems long before the “others”.
