  • Method of modular verification of a configuration of a device
    Patent number: 10803163
    Abstract: To ensure a simple and secure verification of a device, in particular of a safety controller, a method of verifying a configuration of a device, in particular of a safety controller, is provided, said method comprising the steps of subdividing the configuration of the device into at least two part configurations that are validated, of allocating the part configurations to at least one part configuration sequence in which a dependence on a verification of the part configurations on one another is predefined, of determining parameters of each part configuration, with the parameters being used for verifying the respective part configurations, of calculating a single checksum that reproduces the verification of the part configurations, with the single checksum of a preceding part configuration being recalculated in the verification of a part configuration following in the part configuration sequence and with the verification of the preceding part configuration being confirmed on an agreement of the single checksu
