Industrial automation packaged power solution for intelligent motor control and intelligent switchgear with energy management
First Claim
1. A method of providing time synchronization of facility wide data between a process automation system with one or more control devices to control one or more processes and an electrical automation system with one or more intelligent electrical devices (IEDs) to provide power to the process automation system, the method comprising:
- distributing a time signal from a timing device through a first network operatively coupled with the control devices of the process automation system, wherein the control devices include a variable frequency drive (VFD);
distributing the time signal from the timing device through a second network operatively coupled with the IEDs of the electrical automation system, wherein the timing device is connected to a first switching device to distribute the time signal to the first network and the timing device is connected to a second switching device to distribute the time signal to the second network;
shutting down a process of the one or more processes during a peak demand time period by using the process automation system to gather information from the electrical automation system; and
executing an add-on instruction (AOI) in a process controller of the process automation system to selectively convert unsigned data from the IED into signed data and to scale the data from at least one of the IEDs according to user-defined scale factors to provide scaled data values for use by the process controller in controlling at least one process for the time synchronization of the facility wide data.
