Method and control system for controlling and/or monitoring devices

A determining module for a distributed database system or for a control system having a distributed database system for controlling and/or monitoring devices, comprising:

• a first interface for receiving or retrieving control instructions;
• and
• a first evaluation unit, wherein:
• the first evaluation unit assigns execution requirements to the control instructions,
• an executability of the control instructions by nodes of a distributed database system or by devices is ascertained on the basis of the execution requirements,
• the execution requirements comprise device-specific requirements and/or presupposed control instructions,
• the first determining module comprises a cache module,
• the cache module comprises a prescribed number of entries,
• the entries store control instructions already executed by the devices with their associated execution requirements and/or store presupposed control instructions already executed by the devices.

A device comprising:

• a first communication module for receiving control transactions, wherein the distributed database system provides the control transactions, wherein:
• the control transactions comprise control instructions for the device,
• the control transactions comprise execution requirements,
• the execution requirements comprise device-specific requirements for the device and/or presupposed control instructions,
• the applicable execution requirements are assigned to the respective control transactions,
• a first checking module for checking the respective execution requirements for an execution of the control instructions of one of the control transactions by the device, wherein
• checking is performed to ascertain whether confirmation transactions for the presupposed control instructions of the respective execution requirements of the respective control transaction are available in the distributed database system;
• and
• a first execution module for executing the control instructions by means of the applicable device on a basis of a result of the checking.

A method for the computer-aided assignment of execution requirements for control instructions, comprising:

• receiving or retrieving control instructions;
• assigning execution requirements to the control instructions, wherein:
• an executability of the control instructions by nodes of a distributed database system or by devices is ascertained on the basis of the execution requirements,
• the execution requirements comprise device-specific requirements and/or presupposed control instructions,
• the distributed database system is a blockchain, and
• storing entries in a cache module, wherein:
• the cache module can store a prescribed number of entries,
• the entries store control instructions already executed by the devices with their associated execution requirements and/or store presupposed control instructions already executed by the devices.

A method for the computer-aided control of devices, comprising:

• assigning execution requirements to the control instructions, wherein:
• an executability of the control instructions by nodes of a distributed database system or by devices is ascertained on the basis of the execution requirements,
• the execution requirements comprise device-specific requirements and/or presupposed control instructions,
• storing entries in a cache module, wherein:
• the cache module can store a prescribed number of entries,
• the entries store control instructions already executed by the devices with their associated execution requirements and/or store presupposed control instructions already executed by the devices, and
• storing the respective control instructions with the applicable execution requirements in control transactions, wherein the control transactions are stored in the distributed database system.

A method for the computer-aided control of a device, comprising:

• receiving control transactions, wherein a distributed database system provides the control transactions, wherein:
• the control transactions comprise control instructions for the device,
• the control transactions comprise execution requirements,
• the execution requirements comprise device-specific requirements for the device and/or presupposed control instructions,
• the applicable execution requirements are assigned to the respective control transactions,
• checking the respective execution requirements for an execution of the control instructions of one of the control transactions by the device, wherein:
• checking is performed to ascertain whether confirmation transactions for the presupposed control instructions of the respective execution requirements of the respective control transaction are available in the distributed database system;
• and
• executing the control instructions by means of the applicable device on the basis of a result of the checking.
