A system includes a safety controller that, in operation, interrupts power to industrial automation devices or puts the system into a safe state upon command of a human operator. The system also includes an emergency stop switch circuit actuatable by a human operator and a human machine interface in data communication with the safety controller and the emergency stop switch circuit. The human machine interface includes integrated safety circuitry that, in operation, detects a change of state of the emergency stop switch circuit and provides a signal to the safety controller to interrupt power to the industrial automation devices or put the system into a safe state.

An emergency stop system includes: an emergency stop switch including an operation button, a state output unit which outputs a state different in accordance with whether or not the operation button is pushed down, and an attachment unit which attaches the operation button and the state output unit to the mobile device in a detachable manner in such a manner that the state of the state output unit is positioned at a side facing a camera of the mobile device at the time of attachment to the mobile device; and an information processing unit determines in accordance with an image related to the state of the state output unit as imaged by the camera whether to output an emergency stop signal indicating an emergency stop of the machine operated by the mobile device or to output an emergency stop signal indicating no emergency stop of the machine.

A device for failsafe monitoring a number of passes of a moving machine part through a defined movement region comprising an input for receiving an encoder signal, which represents a motion value of the moving machine part. The device further comprises a failsafe evaluation unit for providing a failsafe shutdown signal as a function of the number of passes of the moving machine part through the defined movement region. The failsafe evaluation unit is configured to determine the number of passes of the moving machine part through the defined movement region from the motion value.

A control device for controlling a machine or system includes a monitoring unit designed and configured to monitor the functional state of a second control unit such that, when the second control unit is in an activated functional state, by which the machine or system is put into a safe state, the monitoring unit connects at least one input means associated with the second control unit to a first control unit such that non-safety-relevant functions of the machine or system can be triggered by manual actuation of the input means, as long as the second control unit is in its activated functional state in which the input means is not connected to the machine or system as a proper safety switching means.

A control system for technical installations includes at least one electronic manual operator-control instrument that can be carried and used mobilely by an operator-control person for influencing and observation of the control system or a connected technical installation. The instrument has a wireless communication interface and a communication interface established via a connecting cable. At least one safety switching element actuated by the person on the manual operator-control instrument can at least terminate potentially hazardous control commands or movement sequences. The hard-wired communication interface includes a contact-based plug interface on the instrument having a first coupling element on the instrument and a second coupling element coupled and decoupled as needed relative to the first coupling element. At least one termination indicator on or in the connecting cable directly in or near the second coupling element can be sensed electronically by a termination-indicator detector.

A wearable instrument configured to be wearable by a user includes an inertial sensor, a judgment unit configured to judge whether an output value of the inertial sensor meets a predetermined condition, and an output unit configured to output an operation permission signal for instructing a control device configured to control operation of a machine to permit operation of the machine in a case in which the output value meets the predetermined condition.

Emergency stop pressure sensors 17 are installed on both side surfaces of a movable link 11 of a robot arm 14 of an assembly robot. When a worker S unintentionally walks in a swing range Ra of the robot arm 14 and contacts the emergency stop pressure sensor 17, a detection signal is transmitted to a control unit 19, and the control unit 19 shuts power transmission to a driving source swinging the robot arm. The emergency stop pressure sensor 17 has a first electrode and a second electrode constituting a pair of electrodes and an intermediate layer formed of rubber or a rubber composition, which is disposed between the pair of electrodes, the intermediate layer generating power upon deformation caused by contact with a contacted body (the worker). A side of the intermediate layer in a laminate direction undergoes surface modification treatment and/or inactivation treatment. With this treatment, the one side and the other side of the intermediate layer have different degrees of deformation to the same deformation adding force.

A machine control and data logging station, intended for use with a saw or other machine tool, features a processor which monitors a number of input lines, a real time clock and time stamp function. Any change of input signals from the machine tool will be recorded in flash memory. Both wired and wireless outputs may read the memory at any given time. Optionally, hardware or software data communication encryption may be employed to provide increased confidentiality and security. The station continually monitors sensor inputs and can react automatically to emergency-stop the machine tool upon sensing a dangerous condition.
