Disclosed is a method including obtaining a graphical representation including information on one or more performance metrics associated with an industrial automation device, determining a target operating point associated with the industrial automation device based at least partly on the graphical representation, obtaining a target reference value and one or more operating limits for the industrial automation device, obtaining operational information associated with usage of the industrial automation device, and determining one or more control parameters for the industrial automation device, wherein the one or more control parameters are determined based at least partly on the following: the target reference value, the one or more operating limits, the operational information, and the target operating point.

Determining control parameters for an industrial automation device

According to an aspect, there is provided method for commissioning a drive. First, a local network is established between a wireless computing device, one or more wireless sensor devices and a drive. Each wireless sensor device is configured to measure one or more physical quantities associated with an industrial system controlled by the drive. The wireless computing device configures wirelessly the drive and the one or more wireless sensor devices for performing measurements. In response to receiving one or more measured values from the one or more wireless sensor devices, the wireless computing device displays the information on the one or more measured values on a display for providing guidance for a user of the wireless computing device for adjusting drive parameters of the drive.

Commissioning of industrial processes equipped with wireless sensors

According to an aspect, there is provided a functional safety, FS, watch-dog timer circuit for a computing device of a frequency converter controlling a motor. The FS watchdog timer circuit is configured to trigger a safe state of the frequency converter in response to a timer of the FS watchdog timer circuit expiring. Moreover, the FS watchdog timer circuit is configured to reset the time in response to receiving a first refresh signal from the computing device funning FS software using non-inverted logic as well as in response to receiving a second refresh signal from the computing device running the FS software using inverted logic.

Functional safety software concept for motor drives

An industrial automation device with a token to be used as authentication information in information exchange between a first cloud service and the industrial automation device, a mobile device is connected to the industrial automation device and to a cloud service that is the first cloud service or a second cloud service. After authenticating the user of the mobile device to the cloud service, a token is generated by the cloud service to the first cloud service, and forwarded via the mobile device to the industrial automation device. If the cloud service that generated the token is the second cloud service, the token is forwarded via the mobile device, after the mobile has been authenticated in the first cloud service, the first cloud service. Thereafter the industrial automation device and the first cloud service may communicate directly with each other using the token for authentication.

Industrial automation device and cloud service

According to an aspect, there is provided a method for evaluating safety of a speed of a motor controlled by a frequency converter. The method includes, first, measuring first, second and third phase currents of three-phase electric power fed from the frequency converter to the motor and forming first, second and third current measurement pairs based thereon. Then, the speed of the motor is estimated separately based on each measurement pair to produce respective first, second and third estimates for the speed of the motor. A voting logic is applied to the first, second and third estimates for the speed of the motor. A voting logic is applied to the first, second and third estimates. An output of the voting logic is fed to a safety logic controlling at least one safety function of the frequency converter. The output of the voting logic includes an estimate for the speed of the motor and an indication whether or not said final estimate is valid according to the voting logic.
