Data reproduction device for industrial plant
View Patent ↗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.
1. A data reproduction device for an industrial plant, the data reproduction device being connected to an input/output device that connects to devices constituting the industrial plant and a programmable logic controller that controls the devices, via a control network, the data reproduction device for the industrial plant comprising:
a processor to execute a program; and
a memory to store the program which, when executed by the processor, causes the data reproduction device to execute the following steps:
acquire various pieces of process data output to the control network from the programmable logic controller and the input/output device;
accumulate the various pieces of process data at each time;
display on a first graph, a temporal variation of first process data, and move a time range of data displayed on the first graph in accordance with a change of time pointed to by a first time cursor on the first graph;
display on a second graph, a temporal variation of second process data, and move a time range of data displayed on the second graph in accordance with a change of time pointed to by a second time cursor on the second graph;
store a pointed to by the first time cursor and changes a time pointed to by the second time cursor to the time Ta, and thereby causes the 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;
reproduce the respective pieces of process data displayed on the first graph and the second graph in a coordinated manner;
define, by a graph definition file, a plurality of pieces of process data to be displayed on one graph, the pieces of process data being defined for each graph;
in response to a name of the first process data displayed on the first graph being selected, based on the graph definition file, display a list of graphs that include the first process data; and
in response to a third graph being selected from the list, from among the various pieces of process data, display a temporal variation of each process data associated with the third graph on the third graph and move a time range of data displayed on the third graph in accordance with a change of time pointed to by a third time cursor on the third graph;
change a time pointed to by the third time cursor to the time Ta and thereby display, on the third graph, each piece of process data of the same time as that of the first process data displayed on the first graph; and
reproduce each piece of process data displayed on the first graph and the third graph in a coordinated manner.
2. The data reproduction device for an industrial plant according to claim 1 , wherein the program causes the data reproduction device to:
acquire abnormal state data of the industrial plant output from a monitor control device to the control network;
accumulate the abnormal state data at each time;
display the abnormal state data in an alarm list in chronological order;
store a time Tc of one piece of the abnormal state data selected from the alarm list, change a time pointed to by the first time cursor to the time Tc, and thereby display the first process data of the same time and the abnormal state data on the first graph and the alarm list; and
reproduce each piece of data displayed on the first graph and the alarm list in a coordinated manner.
3. The data reproduction device for an industrial plant according to claim 2 , wherein the program causes the data reproduction device to, in a case where the time Tc of abnormal state data selected on the alarm list continuously changes by an operation on the alarm list, change a time pointed to by the first time cursor to the time Tc in synchronization with a change of the time Tc, and thereby move a time range of data displayed on the first graph in synchronization with a time range of data displayed on the alarm list.
4. The data reproduction device for an industrial plant according to claim 1 , wherein the program causes the data reproduction device to:
acquire operation history data of the monitor control device output from a monitor control device to the control network;
accumulate the operation history data at each time;
display the operation history data on an operation history list in chronological order;
store a time Td of one piece of the operation history data selected from the operation history list, change a time pointed to by the first time cursor to the time Td, and thereby cause the first process data of the same time and the operation history data to be displayed on the first graph and the operation history list; and
reproduce each piece of data displayed on the first graph and the operation history list in a coordinated manner.
5. The data reproduction device for an industrial plant according to claim 4 , wherein the program causes the data reproduction device to, in a case where the time Td of operation history data selected on the operation history list by an operation on the operation history list changes continuously, change a time pointed to by the first time cursor to the time Td in synchronization with a change of the time Td, and thereby move a time range of data displayed on the first graph in synchronization with a time range of data displayed on the operation history list.
6. The data reproduction device for an industrial plant according to claim 1 , wherein the program causes the data reproduction device to, in a case where the time Ta pointed to by the first time cursor continuously changes by an operation on the first graph, change a time pointed to by the second time cursor to the time Ta in synchronization with a change of the time Ta, and thereby move a time range of data displayed on the second graph in synchronization with a time range of data displayed on the first graph.
7. The data reproduction device for an industrial plant according to claim 1 , wherein the program causes the data reproduction device to, in a case where the time Ta pointed to by the first time cursor continuously changes by an operation on the first graph, change a time pointed to by the third time cursor to the time Ta in synchronization with a change of the time Ta, and thereby move a time range of data displayed on the third graph in synchronization with a time range of data displayed on the first graph.
