History dialog

History Dialog

This dialog displays the data logged by each controller on the LAN in table or graphical form. In addition to data logging by the controllers, iNetGrow allows data logging on the PC (see Data Logging on the PC).

A separate tab immediately above the main window displays the controllers in the list of controllers. Select a controller by clicking on its tab. The main window lists the modules connected to the selected controller. Under each module, a list of inputs and outputs that are currently logged is displayed.

Also see: Data Logging on the Controllers, Data Logging on the PC.

Selecting Data to Log

Any named variable connected to a module of the controller may be logged. Use the Setup Network dialog to establish named variables and to select the ones to be logged on the controller.

Navigation

Use the left and right arrow buttons on the top right to scroll back and forth through the logged data. These arrow buttons function just like a CD player.

The logged data are displayed in a graphical format. Each time you click the “Graph” button, a new graph is constructed, showing the user selected variables.

This command removes the currently selected graphic.
