A power grid monitoring system for determining a cause of a lateral trouble ticket. The power grid monitoring system can determine a cause of a lateral trouble ticket in response to receiving the lateral trouble ticket. The power grid monitoring system associates a set of smart meters with a first, penultimate and last transformer downstream from a given lateral. The power grid monitoring system pings each smart meter in the set of smart meters to indicate a state of the first, penultimate and last transformers of the given lateral. Accordingly, the power monitoring system determines a cause of a lateral trouble ticket associated with the given lateral based on results of the pings to the set of smart meters associated with the first, last and penultimate transformers. The power grid monitoring system can further augment the lateral trouble ticket with information characterizing the cause of the lateral trouble ticket.

A robot control device configured to control a robot includes a first memory part configured to store work data, a second memory part configured to store restoring data, a calculating part configured to perform an operation instructing process configured to read the work data and generate an operating instruction to the robot, and a data evacuation process configured to determine whether the operation instructing process operates normally, and when the calculating part determines that the operation instructing process does not operate normally, coincide the restoring data with the work data, and an operation controlling part configured to control operation of the robot based on the operating instruction.

A plurality of system control devices respectively include network interfaces for communicating with each other via a network. One of the plurality of system control devices functions as a master system control device, and the remaining system control devices function as slave system control devices. The master system control device transmits a control command to the slave system control devices by means of the network interface. The slave system control devices receive the control command by means of the network interfaces and supply an operation command to abatement devices in accordance with the control command. When unable to communicate with the master system control device, the slave system control devices either function as master system control devices or enter stand-alone operation mode.

A task resumption system including processing circuitry that receives a task resumption specification for task resumption by a device when the device, which sequentially performs multiple tasks, stops during processing, acquires a current state of the device, acquires a resume state corresponding to the task resumption of the device, causes the device to transition from the current state to the resume state, and causes the device to resume the task according to the resume state.

A program restart assisting apparatus acquires time series data of a physical amount detected in machining, detects a change point on which a machining state of the machining is changed based on the acquired data, and records the change point of the machining state as a restartable point. Then, the program restart assisting apparatus selects a restart execution point from among the recorded restartable points, with the result that an appropriate restartable point can be easily selected.
