Systems, methods, and devices are disclosed herein for the integrated design and deployment of process control logic and power control logic in the context of industrial automation environments. In an implementation, a human-machine interface communicates with a programmable logic controller to effect control of both manufacturing and electrical devices of an industrial automation process in an integrated control environment displayed on a computing device. The human-machine interface displays objects representing the devices and receives user inputs controlling the operation of the devices including operations such as load-shedding and power transition operations. The human-machine interface also displays high-priority information about the devices. The integrated control is designed in an integrated design environment which includes representations of process control logic for controlling manufacturing devices and of power control logic for controlling electrical devices.

An internal cooling grid is mounted internal to a facility, such as a data center, and includes a plurality of fluid transport elements arranged in a grid pattern with nodes at intersections of the grid pattern. Supply and return manifolds included in the nodes receive (and return) cooling fluid from/to more than two transport elements. Thus, a failure of one or more transport elements does not prevent a node from being supplied cooling fluid from at least a first transport element and a second transport element. In some embodiments, the cooling grid may be operated at a pressure less than one atmosphere, such that any leaks that occur cause air to leak into the cooling grid instead of cooling fluid leaking out of the cooling grid.

A voltage regulation device includes: a plurality of taps; a first electrical contact configured to connect to one of the plurality of taps; a second electrical contact configured to connect to one of the plurality of taps; and a network electrically connected to the first electrical contact and to the second electrical contact. The network is configured to control a voltage differential between the first electrical contact and the second electrical contact or an amount of current that flows in the first electrical contact and the second electrical contact.

The device includes an electric energy source to which an inverter is power-connected, whose output is three-phase with symmetrical power distribution. It further includes an inter-phase power transfer module which is power-connected to the inverter and comprises at least one first power board including at least three power transistors. The inter-phase power transfer module has a data interface and has a first output with asymmetrical power distribution into three phases, wherein the first output is further connected to a distinctive nodal point, this distinctive nodal point being power-connected to a load. Through a measuring module, the PLC control system is also connected to the distinctive nodal point, the PLC control system being further connected also to the inverter and the data interface. This arrangement ensures that the power supplied to the load reflects in each phase the power consumed by the load. The device further offers additional possibilities to control energy production, consumption and storage.

This power supply unit of a control system outputs a notification signal to a calculation unit when a time in which an input voltage becomes smaller than a threshold voltage exceeds a prescribed first measurement time. When detecting that a predetermined second measurement time has elapsed after the notification signal has been received, the calculation unit outputs an instruction signal instructing the execution of a process before a stop in preparation for a prescribed stop of power supply, and executes the process before the stop in place of the current process. Settings of the threshold voltage and the second measurement time are configured to be changeable by means of an external operation.

A power distribution grid for a facility, such as a data center, is located within the facility. The power distribution grid includes a plurality of power transport elements arranged in a grid pattern and nodes located at intersections of the grid pattern. Electrical loads are supplied power via respective nodes of the power distribution grid. Also, each node is supplied power from more than two transport elements, such that one or more transport elements can fail and electrical loads connected to a particular node associated with the failed transport elements continue to receive electrical power supplied to the particular node from at least two different transport elements.

A power supply device for the electrical power supply of electrical components from a power source, wherein the power supply device has at least one communication unit by which the power supply device is designed for data communication with an external computer device, wherein the power supply device has connections for supplying the electrical power for the power supply of the electrical components, wherein the power supply device has at least one controllable digital or analog output connection and/or at least one digital or analog input connection as a further connection, wherein in the case of a controllable digital or analog output connection, this can be controlled by the external computer device via the communication unit and in the case of a digital or analog input connection an input value can be read from this input connection via the communication unit by the external computer device.

A control unit included in a PLC generates power-cut retaining information to be retained at a power cut, and stores the generated power-cut retaining information into a main memory. The control unit includes a file system unit for reading and writing target information from and into a nonvolatile memory. When the file system unit receives a power cut notification indicating a cut of power fed while reading or writing target information from or into a nonvolatile memory, the file system unit stops the reading or writing process, and writes the power-cut retaining information stored in the main memory into the nonvolatile memory using power fed from the auxiliary power supply.

The present disclosure relates to an interface conversion device of a programmable logic controller (PLC) system and a PLC system thereof. The interface conversion device of a PLC system according to an embodiment of the present disclosure is an interface conversion device that is applied to a PLC system including a base unit that controls an operation of the PLC system, a plurality of expansion modules that operate under the control of the base unit, and an interface that is a communication line between the base unit and each of the expansion modules, and is configured to connect between a first interface for parallel communication and a second interface for serial communication.
