GATEWAY DEVICE, GATEWAY CONTROL METHOD, AND NON-TRANSITORY COMPUTER READABLE MEDIUM - A simplified explanation of the abstract

This abstract first appeared for US patent application 18244718 titled 'GATEWAY DEVICE, GATEWAY CONTROL METHOD, AND NON-TRANSITORY COMPUTER READABLE MEDIUM

Simplified Explanation

The abstract describes a gateway device that facilitates communication of safety data between a safety input/output unit and a safety controller. The gateway device includes a state monitoring control section and a safety control section. The state monitoring control section manages the control state of the safety control system, which can be either a safety state or a non-safety state. It controls the transition of the control state by using safety data received from the safety input/output unit and state transition information. When the control state transitions from the non-safety state to the safety state, the safety control section generates safety data to be transmitted to the safety input/output unit.

  • A gateway device relays safety data between a safety input/output unit and a safety controller.
  • The device includes a state monitoring control section and a safety control section.
  • The state monitoring control section manages the control state of the safety control system.
  • The control state can be a safety state or a non-safety state.
  • The state monitoring control section controls the transition of the control state using safety data and state transition information.
  • When the control state transitions from the non-safety state to the safety state, the safety control section generates safety data to be transmitted to the safety input/output unit.

Potential Applications

  • Industrial safety systems
  • Process control systems
  • Manufacturing automation

Problems Solved

  • Facilitates communication of safety data between different components of a safety control system
  • Enables efficient monitoring and control of the safety state

Benefits

  • Improved safety in industrial environments
  • Enhanced control and monitoring capabilities for safety systems
  • Streamlined communication between safety input/output units and safety controllers


Original Abstract Submitted

A gateway device () relays communication of safety data between a safety input/output unit () and a safety controller () that controls the safety input/output unit (), and includes a state monitoring control section () and a safety control section (). The state monitoring control section () manages a control state that is a state corresponding to a state of the safety control system () and is one of a safety state and a non-safety state, and controls a state transition of the control state by applying safety data that the gateway device () has received from the safety input/output unit () to state transition information that indicates a state transition concerning the control state. When the control state has transitioned from the non-safety state to the safety state, the safety control section () generates safety data that indicates the safety state and is to be transmitted to the safety input/output unit ().
