Abstract

A system includes a motor and a control system operating as a master controller with respect to at least one function, the control system including an automation system with a user interface having a display connected to the automation system. A controller is located remotely from the control system and coupled to a pump or the motor. The controller operating as a slave controller with respect to the at least one function when connected to the control system. The controller is in communication with the motor and the control system, and transmits information to and receives information from the control system over at least one communication link. The controller operates independently to control the motor when disconnected from the control system.
