A debug support device includes: a root device extraction unit that extracts, from a sequence program that includes a circuit block including a plurality of devices, a result device on the basis of an association between a factor device that contributes to determination of a value of another device and the result device having the value determined by the factor device; a related device retrieval unit that retrieves, as a related device, each and every one of the factor device(s) that determines the value of the result device; and a display control unit that outputs group information to a display device. The group information is information on a group, associating the result device, the value of the result device, the related device, and a value of the related device.

A system for controlling drilling unit apparatus includes a plurality of drilling unit apparatus each operated by a corresponding controller. Any one or more of the controllers is in signal communication with either or both of (i) at least one sensor that generates a signal related to an operating condition of the drilling unit apparatus and (ii) at least one other of the controllers to accept as input therefrom a signal related to an operating state of the corresponding drilling unit apparatus. A plurality of time reference signal receivers is each in signal communication with a corresponding controller. An absolute time reference signal transmitter is in signal communication with each time reference signal receiver such that any one or more of the controllers operates its respective drilling apparatus in response to either or both of (i) the sensor signal and (ii) the signal from the at least one other controller.

Provided is an extension module for independently storing calibration data, including: a first interface, adapted to receive a first external input signal; a second interface, adapted to output the first output signal of the extension module; a signal processing circuit, connected between the first interface and the second interface; and a first memory, the first memory storing first calibration data, and the first calibration data being associated with the extension module. Furthermore, also provided is a component using the above extension module, and a component calibration method. On the one hand, the extension module of an embodiment may share an ADC sampling circuit on a main module, so that the manufacturing cost of the extension module is reduced. On the other hand, an embodiment can facilitate the replacement of different extension modules for the main module without repeated calibration.

A terminal (100) includes a start assist tool (120) that classifies, into multiple groups, multiple remote modules (400) including channels (CH) connected to production line devices (500) as control targets, sets, based on information about the groups, an operation mode of a remote module belonging to a specific group of the multiple groups to a first operation mode to perform operational checks, and forms an image to display an operation of the remote module belonging to a first group.

Disclosed are a PLC system, and a method for controlling an input/output refresh period thereof. A PLC system according to an embodiment of the present disclosure comprises: a memory for storing an integrated operation program in which an input/output refresh run command is added and compiled through a program supporter; and a central processing unit which sequentially performs arithmetical processing of a plurality of control programs included in the integrated operation program, to control an operation of a plurality of expansion modules, wherein when arithmetical processing of at least one control program among the plurality of control programs has been completed, the central processing unit outputs processing result data of the at least one control program for which arithmetical processing has been completed, according to an input/output refresh run command which is additionally input.

An automation network comprises at least one master subscriber, at least one switch, and at least one subscriber. The master subscriber comprises master ports, the switch comprises switching ports, and the subscriber comprises ports, each comprising a transmitter and a receiver. The master subscriber is configured to output first and second telegrams to first and second switching ports via first and second master ports and first and second master communication paths. The switch is configured to forward the first telegram to a first port of a subscriber via a first communication path, and to forward the second telegram to a second port of a subscriber via a second communication path. In error mode, the switch and the subscriber are configured to return the first telegram to the master subscriber via the first master port, and/or to return the second telegram to the master subscriber via the second master port.

A controller for controlling a control object includes a communication interface, an instruction executor, and an access processor. The communication interface accesses a database device. The instruction executor executes a user program including an access instruction for accessing the database device, the user program being associated with control of the control object. The access processor generates an access request in response to execution of the access instruction and causes the communication interface to transmit the access request. The access processor extracts an access request satisfying a prescribed condition from an error list including access requests recorded when access to the database device fails and causes the communication interface to retransmit the access request extracted.

Provided is an information processing device including at least one processor which executes an obtaining process for obtaining sensor data transmitted from each of sensors included in a sensor group, a converting process for converting the sensor data, which has been obtained in the obtaining process, into a particular format, and a providing process for providing, to main equipment, the sensor data whose format has been converted in the converting process.

Provided is an information processing device including at least one processor, the at least one processor executing a first obtaining process for obtaining accessory equipment data transmitted from each of pieces of accessory equipment included in an accessory equipment group, a first converting process for converting the accessory equipment data, which has been obtained in the first obtaining process, into a particular format, and a first providing process for providing, to main equipment, the accessory equipment data whose format has been converted in the first converting process.
