Cyberattack-resilient control system design
A method for performing security failover in an industrial production environment includes a programmable logic controller (PLC) receiving notification that a function block (FB) or a function (FC) on the programmable logic controller has been maliciously revised. The PLC next determines whether the function block or the function is also maliciously revised on a failover computing device. If the failover computing device is not maliciously revised, a failover operation is performed by the PLC. This operation includes sending a data block comprising one or more input parameters to the function block or the function and receiving an output data resulting from executing the function block or the function with the data block on the failover computing device.
Development support apparatus, program development support method, and program development support program
A program development support unit includes an arithmetic unit and a storage unit. A ladder diagram editing program and an edited ladder diagram program are stored in the storage unit. The arithmetic unit is configured to execute the ladder diagram editing program to edit the ladder diagram program, and store the ladder diagram program in the storage unit. The arithmetic unit is configured to allocate two-dimensional coordinates to a ladder diagram expressed by the ladder diagram program. The arithmetic unit is configured to detect two-dimensional coordinates and types of circuit elements included in the ladder diagram, and detect two-dimensional coordinates of any vertical connection lines included in the ladder diagram. The arithmetic unit is configured to store the circuit elements, the vertical connection lines, the two-dimensional coordinates of the circuit elements, and the two-dimensional coordinates of the vertical connection lines in the storage unit in association with each other.
Suggesting and/or creating agents in an industrial automation system
An automation system, a method and an apparatus for suggesting and/or creating an agent in an industrial automation system that includes automation devices having a framework which is formed to execute the agent and which at least partially includes a data source that collects and/or processes data of the automation devices, and includes a data sink, in which data, in particular status data, of the data sources is saved, wherein an agent suggestion component processes data of the data sink into clusters via a cluster analysis, and wherein the agent suggestion component makes the clusters available at an interface such that a model for the agents becomes creatable by an agent generation component based on at least one selection of the clusters such that it becomes possible to suggest and/or create agents in a simpler and more efficient manner.
Method for trusted booting of PLC based on measurement mechanism
The present invention discloses a method for trusted booting of PLC based on a measurement mechanism, comprising the following steps: a step of initializing self firmware verification; a step of reading and computing firmware information about a PLC; a step of checking and storing one by one; and a step of verifying at the operation start stage. In the method of the present invention, a chip with a trusted function is used as a core of hardware computation. The PLC extends a Flash bus for loading by hardware of the method of the present invention. The hardware of the method of the present invention recognizes necessary boot information, verifies the integrity of the boot loader necessary for the PLC system through the integrity check method and ensures that the booted PLC system is in a trusted state. On the basis of ensuring validity and feasibility for the safety of a terminal device, the present invention can build a safe and trusted industrial control system operating environment.
Method of logging process data in a PLC controlled equipment
A method of logging process data in a PLC controlled equipment is disclosed. Sections of a PLC application code comprise tasks configured to execute program functions at specific execution rates. Each of the tasks comprise program functions having dedicated memory areas assigned as tags, and each data entry of the process data comprises a tag value and an associated process value. The method comprises receiving process data from the PLC application code, assigning process values to threads of a thread pool, and receiving, for each of the threads, in a respective data table associated with each of the threads, the tag- and process values of the received process data, and determining a hash code for each of the tags according to a hash function of the respective data table for arranging the tag values and the associated process values in the respective data table according to said hash code.
SWAY MITIGATION FOR MATERIAL HANDLING
A vibration control system for a radio controlled device, including a radio controller and a radio receiver. The radio controller is configured to provide control commands to the radio receiver, including activation and deactivation of vibration control. One of the radio receiver or the radio controller includes a vibration control configured to provide vibration control commands to the radio controlled device.

DISTRIBUTED DYNAMIC ARCHITECTURE FOR ERROR CORRECTION
Various systems and methods may be used to implement a software defined industrial system. For example, an orchestrated system of distributed nodes may run an application, including modules implemented on the distributed nodes. The orchestrated system may include an orchestration server, a first node executing a first module, and a second node executing a second module. In response to the second node failing, the second module may be redeployed to a replacement node (e.g., the first node or a different node). The replacement mode may be determined by the first node or another node, for example based on connections to or from the second node.
Method and arrangement for monitoring the status of a production device
Method and an arrangement for monitoring status of a production device configured to implement an industrial process or industrial production with a control device with sensors and actuators, where at least one further sensor is carried through the production device with a product being processed by the production device, where further signals are wirelessly transmitted to a status-monitoring device by the further sensor, and where the signals and/or status information items and the further signals are placeable in relationship with one another to generate status information item about the production device such that it is possible to plan the status monitoring separately from the production device, and possible to combine information items of the industrial control device with the information items and data of a mobile sensor (further sensor) that passes through the production device, such that more precise status information items about the production device status can be acquired.
Relay device for relaying data between devices, control method therefor, and non-transitory computer-readable recording medium therefor
The present invention addresses the problem whereby the number of commands to be transmitted increases in accordance with an increase in the number of devices to be backed up and restored, and processing becomes complex. An IO-Link master is provided with: an upper-level communication control unit which receives an instruction to execute backup in which setting information is acquired from IO-Link devices, and stored in a storage unit; and a backup control unit which executes backup of the plurality of IO-Link devices in accordance with the one received instruction.
