摘要： The control system (1000) includes a programmable logic controller (PLC) (40) to control a device, and a program transmission apparatus (10) to transmit a control program (70) for causing the PLC (40) to control the device. The program transmission apparatus (10) includes a first code generator (113) to generate a first code (71) for verification of presence or absence of a change from the control program (70) by using the control program (70) and confidential data (80). The PLC (40) includes a second code generator (433) to generate a second code by using a receiving program as the control program (70) and the confidential data (80) that is shared with the program transmission apparatus (10), and an executor (435) to execute the receiving program when the first code (71) is identical to the second code.

摘要： A method includes acquiring state variables that characterize an operational state of an industrial plant; acquiring interaction events of a plant operator interacting with the distributed control system via a human-machine interface; determining based on the interaction events, and with state variables as input data, whether one or more interaction events are indicative of the plant operator executing a task that is not sufficiently covered by engineering of the distributed control system. When this determination is positive, mapping the input data to an amendment and/or augmentation for the engineering tool that has generated the application code.

摘要： A program fragmentation unit (131) divides a target program into fragments according to groups of processing. A fragment group extraction unit (132) extracts, from among sets of fragments, each set in which instruction groups match between fragments, as a fragment group. A functionalization candidate extraction unit (136) extracts, from among sets of fragment groups, a set in which instruction groups match between fragment groups, usage patterns of a variable group match between the fragment groups, and types of variables match between the fragment groups, as a functionalization candidate. An output unit (140) outputs information on the functionalization candidate.
