InfinityTrends — history display of parameter changes

Description

Component of SCADA Infinity - InfinityTrends allows viewing and analyzing of parameter changes in time with the help of dependence diagrams and charts.

Provides full recovery of parameter changes, including run value and history from any moment.

Completely fits specification of OPC-access to history data (OPC HDA), determining requirements to subsystem for saving and registration of controlled parameter values, specification OPC DA (access to run data)

Run-time and history display mode

• In run-time mode InfinityTrends gets prompt value of measured parameter directly from input/output server and displays it at a diagram (recorder mode);

• In history mode diagram of parameter changes, recorded during user-set time period, is displayed.

Easy set-up

• Setting up of diagram parameters, adding, deleting and editing of pens during implementation;

• Computing of statistical characteristics of controlled parameters, such as number of signal values for a set time-period, minimal and maximal, processing time of request to history server.

Control of diagram display

• Display of several diagrams on one trend field allows finding of parameter changes dependences, analyzing of technological process dynamics;
• Simultaneous display of several reference lines gives additional information for detailed analysis of parameter changes;

• Setting of simultaneous display of run and history data in one plot area.

Diagram scaling

• Automatic and manual scaling of diagrams - of the whole diagram, horizontal, vertical, selected area of diagram;

• Mode of diagram display during scaling, option of all diagram display in general scale.

Display of trend in charts

• Display of trend in charts allows detailed analysis of technological parameter changes;

• Setting of data display in charts: for all signals, for every particular signal.

Functions of ActiveX-component

• Implementation of InfinityTrends as an ActiveX-component allows easy application of its features with, for example, mnemonic diagrams InfinityHMI, with Microsoft Internet Explorer or other display program, serving as a container.
