Abstract
A method for isolating a plant device of an industrial plant, wherein at least one safety measure is implemented on the plant device in order for work to be done safely on the plant device is provided. Isolation information is communicated to a control and protection system using a data communication unit having a data input that receives data from the plant device. An interface between the data communication unit and a control and protection system of the industrial plant is used to transmit the isolation information from the data communication unit to the control and protection unit. A device for isolating a plant device of an industrial plant to carry out work on the plant device is also provided.
Claims18
A method for isolating a plant device of an industrial plant wherein a safety measure is implemented on the plant device in order to work safely on the isolated plant device, comprising:
- communicating isolation information comprising a first data to a control and protection system of the industrial plant using a data communication unit,
- wherein the data communication unit includes a data input device for receiving the first data from the plant device that identifies the plant device,
- wherein an interface exists between the data communication unit and the control and protection system;
- and
- wherein the first data is input into the data communication unit at the site of the plant device, and an operator communicates the isolation information to the control and protection system via the data communication unit via the interface, and the control and protection system isolates the plant device in response to receiving the isolation information from the data communication unit, and the control and protection system blocks automatic triggering of the plant device as part of the isolation;
- wherein the data communication unit is a portable unit which is brought to the plant device by the operator to receive the first data from the plant device that is to be worked on.
A device for isolating a plant device of an industrial plant so that work may be carried out on the plant device, comprising:
- a data communication unit having a data input for receiving a first data from the plant device that identifies the plant device;
- a control and protection system of the industrial plant;
- and
- an interface for connecting the data communication unit in terms of signaling to the control and protection system,
- wherein the interface transmits isolation information comprising the first data from the data communication unit to the control and protection system;
- wherein the first data is input into the data communication unit at the site of the plant device that identifies the plant device, and the data communications unit enables an operator to transmit the isolation information to the control and protection system via the data communication unit, and the control and protection system isolates the plant device in response to receiving the isolation information from the data communication unit, and the control and protection system blocks automatic triggering of the plant device as part of the isolation;
- wherein the data communication unit is a portable unit which is brought to the plant device by the operator to receive the first data from the plant device that is to be worked on.
