A method is set forth that serves to execute an event-oriented control program on a programmable logic controller of an automation system, wherein the control program comprises a plurality of functional modules, wherein an execution of the individual functional modules is triggered in an event-controlled manner on the occurrence of activation events that are each associated with the individual functional modules, and wherein priorities are assigned to each of the activation events. The method comprises the following steps: detecting activation events that have occurred; and executing the functional modules that are each associated with the activation events that have occurred in an execution sequence defined on the basis of the priorities of the individual activation events.

An execution environment for executing an event-oriented control program of a programmable logic controller, wherein the control program comprises a plurality of functional modules to be successively executed, is configured to execute the functional modules in an event-controlled manner on the occurrence of activation events that are each associated with the individual functional modules. In this respect, the individual activation events of the functional modules to be successively executed form an event chain. The execution environment comprises a monitoring module for monitoring an execution duration of the functional modules of the event chain, wherein the monitoring module is configured to check the execution duration for an exceeding of a predefined time duration.

A farming control system for monitoring and controlling one or more contained farms is described herein. The farming control system includes a local system having a plurality of modules to obtain crop data and perform farming operations on crops. The modules transmit the crop data to and receive the farming operations from a local controller, or a cloud controller when the local controller fails. The local system and the cloud system may use machine learning based on the crop data to determine the farming operations to be performed.

The objective of the present invention is to simplify the transfer of a program that has been edited. A support device, which assists in the development of a program executed by a target device provided in factory automation (FA), carries out a transfer process for transferring the program to the target device. The program includes a control program for controlling a machine and an HMI program for processing a variable used by the control program. When the control program or the HMI program has been edited, the support device simultaneously transfers the control program and the HMI program respectively to a control device and an HMI device.

A ladder display device of the disclosure includes: a ladder circuit storage unit that stores an insertion condition including at least an operation start position of a gesture operation, an operation end position of the gesture operation, and a circuit state of a net on a ladder diagram related to the gesture operation as insertion target ladder circuit information in association with a ladder circuit that is an insertion target; a ladder circuit condition determination unit that, with reference to the ladder circuit storage unit, determines a ladder circuit whose insertion condition is satisfied by a gesture operation performed on the touch panel; a ladder circuit generation unit that generates a ladder circuit determined by the ladder circuit condition determination unit as the gesture operation satisfying an insertion condition; and an edition control unit that inserts a ladder circuit generated by the ladder circuit generation unit into the ladder program.

A control assembly of an automation system, having at least two row modules which are arranged in a row one after the other and have an actual order, includes a control and/or communication module and/or an I/O module, as well as a test module. The row modules are each equipped with an indicator element which can assume two distinguishable states. Further, a test method for the control assembly.

Provided is a technology with which it is possible to access a function unit to be accessed without ascertaining an IP address of the function unit. Provided is a unit comprising: a communication unit for relaying a communication between an external device connected to a first network and another unit connected to a second network; a setting unit for acquiring address information of the other unit in the second network from the other unit and generating setting information in which the address information is associated with an identifier which substitutes for the address information; and a link information generation unit for generating, on the basis of the identifier, link information used to access information on the other unit from the external device.

In a master device (control device) that employs a configuration list, setup change is performed easily without requiring a complicated operation with respect to a partial change in the configuration of a slave-side system on a slave side. A control unit (11) of a control device (10) is configured to perform communication for inquiring about device information to an address in an active configuration list through a communication unit (12), and determine to be abnormal when the result of the communication with respect to a common portion of a slave-side system (20) is different from the device information in the active configuration list.
