This system includes a data collection device, a data accumulation device, and a data reproduction device. The data collection device includes: a first reception unit that receives first signal data transmitted to a first existing network; a second reception unit that receives second signal data transmitted to a second existing network; a count-up unit that counts up a unique collection number at a fixed time interval; and a data synchronization processing unit that associates, when the first reception unit receives the first signal data, the collection number at the time of the reception with the first signal data and associates, when the second reception unit receives the second signal data, the collection number at the time of the reception with the second signal data, and performs accumulation in the data accumulation device.

Playback simulation test system

An industrial plant data reproduction device includes the following. A process data collection unit collects process data regarding a group of devices and materials to be processed by the group of devices. A video data collection unit collects video data in which an object whose image is to be obtained is captured, the object pertaining to the group of devices. A graphic data storage unit stores in advance graphic data indicative of a motion target position of the object whose image is to be obtained for each material specification. A graphic data selection unit selects the graphic data corresponding to the material specifications included in the process data every time each of the materials reaches the object whose image is to be obtained. A display processing unit outputs synthetic data in which the selected graphic data is overlaid on the video data.

Industrial plant data reproduction device

A first graph display processing unit displays, on a first graph, a temporal variation of first process data accumulated in a process data storage unit. A second graph display processing unit displays, on a second graph, a temporal variation of second process data accumulated in the process data storage unit, and moves a time range of the data displayed on the second graph in accordance with a change of the time pointed to by a second time cursor on the second graph. A time coordination unit stores the time Ta pointed to by a first time cursor and changes the time pointed to by the second time cursor to time Ta, and thereby causes second process data of the same time as that of the first process data displayed on the first graph to be displayed on the second graph.

Data reproduction device for industrial plant

A data reproduction device () is a data reproduction device for plant-monitoring control system to be newly connected to an existing networkin which a packet is transmitted/received between a PLC () that is operating and an input/output device (). A setting information storing portion () stores setting information. A process data definition information storing portion () stores process data definition information. A process data acquiring portion () acquires a binary data array stored in the packet. A process data analyzing portion () decomposes the binary data array into a plurality of pieces of process data based on the setting information and, for each of the plurality of pieces of process data, associates one piece of the process data among the plurality of pieces of process data, packet receiving time, and the process data definition information to obtain one piece of process data analysis information.
