The present disclosure discloses a master pattern generation method which is a major pattern in a repeated cycle by analyzing programmable logic controller (PLC) logic, and a method for training a model that may analyze an error of a cycle using the generated master pattern.

The master pattern generation method and the training method for a cycle analysis model according to the present disclosure are different from the related art in that the methods are a technology of processing a machine control language (low-level language) that is difficult for humans to analyze and converting the machine control language into an analyzable language (high-level language), i.e., a machine language processing (MLP)-based technology that analyzes the executed machine language (a language that controls a machine) with a computer and cats be understood by humans.

A smart power system is described. In one or more implementations, the smart power system comprises a microcontroller and a power converter electrically connected to the microcontroller and is configured to convert electrical energy from one form to another. The system also includes a switch element electrically connected to the microcontroller and configured to control distribution of the converted electrical energy to an electrical load. A sense element is electrically connected to the electrical load and to the microcontroller and is configured to monitor the converted electrical energy distributed to the electrical load and to furnish a feedback signal based upon the converted electrical energy. The microcontroller is configured to verify and to monitor the power converter, as well as to control and to monitor distribution of the converted electrical energy to the electrical load based upon the feedback signal.

An industrial controller that integrates execution of a control program on the industrial controller with execution of additional functions on an external processing device is disclosed. Integrating the external processing device provides an improved system for third party development of control functions which may be unique to specific applications. The system manages communication between the industrial controller and the external processing device, manages access to data stored in the industrial controller, and makes the details of the integration transparent to the programmer.

The present invention suppresses the data size of a data frame to be transmitted to a control device at every control period even if oversampling is performed. A counter unit (10) compresses the data size of sampling data (Sd) indicating a second or subsequent count value (Ct) to the number of bits by which the maximum (Vmax) of a count value countable in one sampling processing can be represented.

An expansion base unit (10) includes an input connector (101, 102) communicatively connectable with a cable (C11, C12) to a connector in a previous base unit to allow receipt of a signal from the previous base unit, and a plurality of output connectors (111, 112) that each are communicatively connectable with a cable (C21, C22) to a connector of a plurality of connectors in a subsequent expansion base unit to allow transmission of the signal received by the input connector (101, 102) to the subsequent expansion base unit.

An input/output module (100) includes a standard input/output module unit (4) and a safety circuit unit (5). The standard input/output module unit (4) includes an external interface to connect with a control target device, a standard input/output module controller to receive an input signal from the control target device and transmit the input signal to a control module, or transmit a control signal received from the control module to the control target device, and a first connector including a plurality of connection points. The safety circuit unit (5) includes a diagnoser to diagnose operation states of the control target device and the standard input/output module unit, a second connector including a plurality of connection points and removably insertable into the first connector, and a safety circuit controller to control operations of the standard input/output module unit and the diagnoser with the second connector inserted in the first connector.

A control system includes a control engine that cyclically updates internal state values on the basis of a signal exchanged with a control target; a security engine that executes an incident response operation in response to an incident that possibly occurs in the control system; and a phase update module that updates a phase value indicating an operation state of the control target on the basis of one or more values selected discretionarily in advance by a user from among the internal state values retained by the control engine. The security engine retains operation definition information in which the content of the incident response operation is defined for each phase, and executes a corresponding incident response operation defined in the operation definition information in accordance with the phase value updated by the phase update module.

A control device can modify a first user program and first setting information in the storage unit executed by a control engine respectively using a second user program and second setting information received by the control device. A security engine of the control device verifies identity between the first user program and the second user program, evaluates the validity of setting indicated by the second setting information, and permits or prohibits performance of the above modification based on such a verification result and the evaluation.

Examples of an interface module includes a fan filter unit having a fan and a filter, a housing surrounding a space adjacent to the filter, the housing includes a door, an upper housing surrounding a space adjacent to the fan, a first port provided in the upper housing, a second port communicating to a FFU internal space, the FFU internal space is a space between the fan and the filter in the fan filter unit, and a differential pressure gauge connected to the first port and the second port to detect a differential pressure between an interior of the upper housing and the FFU internal space.
