The invention relates to a safety controller for an actuating drive (2.1, 2.2, 2.3) for controlling a gas flow or a liquid flow in an open-loop or closed-loop manner by means of a flap (3.1, 3.2, 3.3) or a valve, in particular in the field of heating, ventilation, and air conditioning (HVAC) systems, fire-protection systems, and/or room protection systems. A safety circuit (9.1, 9.2, 9.3) is implemented to ensure the energy supply in a safety operating mode if an electricity supply circuit (8.1, 8.2, 8.3) drops off or is lost. A control value output circuit (1.1, 1.2, 1.3) detects status signals, in particular signals of a sensor (11.1, 11.2, 11.3), and/or status parameters of a system and/or a specifiable setting of an adjustment device that can be actuated manually. The safety control value is set to one of at least two different control values (SW1, SW2, . . . ) depending on the status signals so that the safety position of the flap is determined adaptively.

A monitoring device for a programmable controller includes: a display portion configured to display, on a display, a step that is being executed by the programmable controller among a plurality of steps in such a manner that the step can be distinguished from the other steps; a receiving portion configured to receive selection of a step serving as an initial point of reactivation in a case where a facility stops during a continuous operation by the programmable controller; and a change instruction generation portion configured to generate an instruction to the programmable controller so as to cause the programmable controller to restart execution of control processes from the step received by the receiving portion at the time of the reactivation.

This disclosure provides systems, methods and apparatus, and computer programs encoded on computer storage media, for managing Internet of Things (IoT) devices. In one aspect, a processor of a smart meter device may determine a predicted reliability of electrical power. In some implementations, the processor may detect a predicted reliability of restored electrical power following a power outage. The processor may send an indication of the predicted reliability of the electrical power to an IoT device to enable the IoT device to perform an action based on the predicted reliability of the electrical power.

A control circuit includes a latching relay, a power loss activation circuit, and a watchdog circuit. A microcontrol unit (MCU) communicates with the watchdog circuit in a normal operation of the control circuit. As an action of a failsafe precaution in the event of a main power loss or a component failure, the MCU stops communicating with the watchdog circuit, at which point the watchdog circuit instructs the power loss activation circuit to continue operation of the control circuit. The control circuit further operates to implement mitigation operations in the event of a main power loss or component failure.

A motor controller and methods of controlling a variable speed motor using the motor controller after a power-loss event are described. The motor controller is configured to be coupled to a motor. The motor controller includes a computing device configured to determine power is being supplied to the motor controller a power-loss event. The computing device is also configured to operate the motor in accordance with a predetermined operating schedule such that the computing device operates the motor at a first speed for a first time period, and after completion of the first time period, the computing device operates the motor at a second speed for a second time period.

This system is a data collection system collecting a robot operation-related data/signal from a robot controller. The data collection system includes a data collection condition setting unit setting a collection condition of the robot operation-related data/signal from the robot controller and a data storage unit storing the robot operation-related data/signal collected from the robot controller. A shared memory inside which the data storage unit and the data collection condition setting unit are formed is formed in a substrate which can be mounted on an expansion slot of the robot controller. According to this system, a data collection function can be post-installed to an existing robot controller so as to arbitrarily select and collect various data on the robot operation.
