Abstract: At least some of plural control target devices are classified so as to belong to one of plural groups. A control device holds identification information specifying a belonging control target device and information about a behavior of a remaining control target device in detecting an abnormality of a control target device belonging to an identical group with respect to each group. The control device detects the abnormality of each of the plural control target devices based on data exchanged with the plural control target devices in executing a user program. When the abnormality is detected in one of the plural control target devices, the control device refers to the identification information to specify an abnormal group to which the control target device in which the abnormality is detected belongs, and the control device refers to the information about the behavior to control action of the abnormal group.

Abstract: The communication master repeats transmission of first information indicating a counter value of a synchronization counter of the communication master to the one or more communication slaves through a network. Each of the one or more communication slaves updates the counter value of the synchronization counter of each of the one or more communication slaves based on the received first information upon receiving the first information from the communication master. The communication master manages a total number of pieces of the first information transmitted for each of the one or more communication slaves, and estimates synchronization accuracy with respect to the communication master for each communication slave based on a number of transmissions of the first information for each communication slave.

Abstract: The convenience of a design of a system is improved by making it easier to verify consumed electric power when designing and constructing the system. An operation screen is displayed upon execution of on a PC for supporting the design of a control system. The configuration of a control system can be controlled in an editing region, and unit images representing an I/O unit are connected in order to a unit image representing a communication coupler. A power supply unit can be inserted into this configuration. An icon indicates a shortage of electric power to the units downstream of the unit indicated by a selected image. When a user mouses the pointer over the icon, the detailed meaning of the icon is displayed in a message. The designer is thus capable of easily verifying the position at which a power source supply unit should be added.

Abstract: A safety control unit includes: a memory; a computation control part; and an input and output unit for connecting the computation control part to a safety input device and an output device to be safely controlled. A system program includes a data refresh program for executing a data refresh of safety control data of the safety input device and the output device and the control data of the memory via the input and output unit. If the computation control part receives a change of a control program, the computation control part stops executing the control program. The computation control part executes the change of the control program while executing a part of the system program including the data refresh. The computation control part resumes executing the control program.
