The present disclosure relates to a PLC device capable of variably setting parameters, the PLC device converting variable parameters into a parameter program command rather than into the parameters themselves so as to store same in a program memory, thereby enabling parameter values to be actively changed according to changes in sensor values of factory equipment.

The present invention belongs to the field of control systems, in particular controllers of different processes. The invention relates to a modular controller for energy management, which can be adapted with regards to the manager's needs. The invention additionally relates to a method of modular assembly for different input signals as well as a method of energy management using the said controller. The essence of the invention is in that the controller has a housing inside which nine empty slots are provided; said slots may be equipped with arbitrary components with regards to the system to be controlled with the controller. Said empty slots may be provided with one or more of the following components such as relay, digital output, digital input, analogue output, analogue input, optically separated input, reading current signal, reading temperature sensor, etc. The controller may control usage or manufacture of gases, electricity and/or heat.

A simulation device that estimates a behavior of a system including a control device that controls a target includes a program execution module, a three-dimensional virtualization module, a setting module, and a reception module. The program execution module executes a simulation program estimating the behavior. The three-dimensional virtualization module virtually constructs the system in a three-dimensional virtual space. The setting module executes setting generating or updating data referred to during the execution of the simulation program. The reception module receives a user operation to the simulation device. The setting module selectively executes setting based on a position in a three-dimensional virtual space or setting based on an operating condition according to the user operation.

A control device that has received a request for starting the execution of a control program issues a comparison request to two control devices that store shared information, the control devices that have received the comparison request each compare unique information created by the own control device with unique information on the own control device contained in a piece of the shared information stored in each control device, and when the comparison result satisfies a prescribed condition, the execution of the control program is permitted.

A control device (10) connectable to an imaging device (42) for controlling a control-target device includes an execution unit (11) that executes a control program to control the control-target device and outputs a first trigger signal when data (112) variable with execution of the control program satisfies a first condition, a receiver (63) that repeatedly receives image information indicating an image captured by the imaging device (42) and receives, from an environment detector including the imaging device (42) or a device (41) different from the imaging device, a second trigger signal indicating detection of environmental information including a result of detection performed by the environment detector satisfying a second condition, and a saver (66) that saves the image information received by the receiver (63) into a second storage (67) when receiving the first trigger signal from the execution unit (11) or receiving the second trigger signal with the receiver (63).

A secure control system includes a network of multiplexers that control end/field devices of an infrastructure system, such as an electric power grid. The multiplexers have a default secure lockdown state that prevents remote access to data on the multiplexers and prevents modification of software or firmware of the multiplexer. One or more of the multiplexers include a physical authentication device that confirms the physical proximity of a trusted individual when remote access is requested. A user accesses the network and one of the multiplexers remotely by way of login credentials. The trusted individual confirms the identity of the remote user and operates the physical authentication device connected with and in proximity to that multiplexer, thereby confirming that the remote user can be trusted to access data and reconfigure the multiplexers. The multiplexer connected with the physical authentication device generates a token that is passed to each of the multiplexers that the remote user needs access to. The token may specify a time period, after which, the multiplexers will reenter secure lockdown mode.

Embodiments herein are directed to an assembly having a plurality of machines, a first programmable logic controller device and a second programmable logic controller device commutatively coupled to the first programmable logic controller device. The second programmable logic controller device includes a human machine interface having a display and displaying a plurality of user inputs. A processing device communicatively coupled to the display and a storage medium. The storage medium includes one or more programming instructions that, when executed, cause the processing device to prompt a user to select a desired program, to input a desired line speed time, and to input a plurality of line control data. The data is converted into a simulated data and transferred to the first programmable logic controller device, which causes at least one machine of the plurality of machinery to move in a predetermined manner based on the simulated data.

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 computer displays, in an integrated design environment, representations of process control logic for controlling manufacturing devices an industrial automation process and of power control logic for controlling electrical devices in the industrial automation process. The computer further deploys the process control logic and the power control logic to a programmable logic controller (PLC) that controls the industrial automation process.

To efficiently collect and transfer monitoring target data in a PLC. The PLC includes a first execution engine, a holding section, and a second execution engine. Further, the PLC collects data stored in a collection target holding section according to predetermined collection setting, accumulates collected time-series data in a first buffer, and transfers the time-series data stored in the first buffer to the second execution engine via a bus. The second execution performs data processing of the transferred time series data, generates display data to be displayed on a dashboard, and provides the display data to an external computer.
