Abstract
The invention relates to an industrial process controller comprising at least three field devices coupled to one another by means of a data link, with the field devices controlling and/or monitoring an industrial process, wherein the field devices are configured to store a block chain, wherein the block chain comprises a plurality of blocks, and wherein the blocks store use data. The process controller is characterized in that the field devices are configured to delete one or more blocks from the block chain and to adapt the block chain to the change caused by the deletion.
Claims16
An industrial process controller comprising:
- at least three field devices coupled to one another by means of a data link, with the field devices controlling and/or monitoring an industrial process,
- the field devices being configured to store a block chain, wherein the block chain comprises a plurality of blocks, and wherein the blocks store use data, and
- the field devices being configured to delete one or more blocks from the block chain and to adapt the block chain to the change caused by the deletion,
- wherein the field devices are configured to perform a recalculation of at least some of the blocks remaining after the deletion.
A method of increasing the reliability of an industrial process controller that comprises at least three field devices coupled to one another by means of a data link, with the field devices controlling and/or monitoring an industrial process,
- wherein the field devices store a block chain, wherein the block chain comprises a plurality of blocks, wherein the blocks store use data,
- and wherein one or more blocks are deleted from the block chain and the block chain is adapted to the change caused by the deletion,
- wherein a recalculation of at least some of the blocks remaining is performed after the deletion.
A field device for an industrial process controller, wherein the field device is configured to control and/or to monitor an industrial process, wherein the field device is further adapted to communicate by means of a data link and to store a block chain, wherein the block chain comprises a plurality of blocks, and wherein the blocks store use data,
- wherein the field device is configured to delete one or more blocks from the block chain and to adapt the block chain to the change caused by the deletion, and to perform a recalculation of at least some of the blocks remaining after the deletion.
