Abstract: A method for real-time data communication between subscribers in an automation network is provided. The automation network includes an active subscriber, a plurality of passive subscribers and at least a connecting unit. The method includes the active subscriber arranging n data packets to be transmitted in a transmission order with a total occupancy time duration of the transmission order, performing an optimizing procedure for determining an optimized transmission order with minimum total occupancy time, and transmitting the n data packets in the optimized transmission order to the passive subscribers. An active subscriber for carrying out the method and an automation network comprising an active subscriber are also provided.

Abstract: A malfunction analysis support program causes a computer to perform a log data acquisition step, an action reproduction step, a three-dimensional data display step, a processing step being at least one of a program operation display step, a waveform display step, or a video display step, and a time synchronization step. The log data acquisition step obtains log data temporally sequentially recording a state of an operational part and input-output data of a control signal. The action reproduction step generates action reproduction simulation data obtained by causing a virtual object-to-be-controlled to reproduce an action based on the log data. The three-dimensional data display step displays the action reproduction simulation data as three-dimensional data. The time synchronization step synchronizes time between three-dimensional data displayed by the three-dimensional data display step and data displayed by the processing step. The three-dimensional data display step displays the three-dimensional data according to display setting information.

Abstract: Even when a tapping screw is used in a soft material, it is determined whether or not a screw tightening defect has occurred. A PLC (10) comprises a determination unit (13) which for a rotational torque data sequence having a predetermined number of data points, generates a normalized torque data sequence that is the amount of change with respect to rotational torque at a first data point of the data sequence, and determines whether screw tightening is defective, on the basis of the normalized torque data sequence.

Abstract: A control device for industrial machines includes a plurality of signal input-output circuits configured such that pulse widths of pulse signals output from the signal input-output circuits are different from each other. The control device detects a fault when a pulse signal output from one of the signal input-output circuits has a pulse width different from the pulse width set to the one of the signal input-output circuits.

Abstract: An automation field device comprises a first, a second, and a third connection pin; and a field device electronics designed to be operated either in a two-conductor mode or in a three-conductor mode. The field device electronics have an energy supply unit designed to provide internal energy supply exclusively by means of the fed current in the two-conductor mode. In the three-conductor mode, an additional auxiliary current is to be fed to the field device electronics via an additional single-wire line connected to the third connection pin, and the energy supply unit is also designed to provide the internal energy supply via the fed current and the fed additional auxiliary current. Furthermore, the field device electronics are designed to use the additionally fed auxiliary current for internal energy supply only if the current fed by means of the two-wire line is not sufficient for the internal energy supply.

Abstract: Systems, methods, and devices are disclosed herein for the integrated design and deployment of process control logic and power control logic in the context of industrial automation environments. In an implementation, a programmable logic controller executes power control logic to control a power control module on the network of the electrical subsystem of an industrial automation process. The power control module relays electrical device information to the programmable logic controller which issues power control commands according to the power control logic. The power and process control logic executed by the programmable logic controller are designed in an integrated design environment which includes representations of process control logic for controlling manufacturing devices of the industrial automation process and of power control logic for controlling electrical devices in the industrial automation process.

Abstract: It is possible to make data for manufacturing devices available in a standard format using an adapter that would automatically interrogate the device and use the information gained from the machine to generate a data translation file. The data translation file could subsequently be used by an agent to interpret a data stream provided by the adapter for the manufacturing device.
