Graphic Trigger Window Interface

Setting a graphic trigger causes a pop-up window to appear, which is called Interface window. This is the main interface for accessing the debugging functions that the graphic trigger window makes available. It consists of several elements, as shown below. 1. Caption bar 2. Controls bar 3. Chart area 4. Variables windowThe Caption BarThe Caption bar at the top of the pop-up window shows information on the location of the trigger which causes the variables listed in the Variables window to be sampled.The text in the caption has the following format:ModuleName#Locationwhere

ModuleName	Name of program, function, or function block where the trigger was placed.
Location	Exact location of the trigger, within module ModuleName.If ModuleName is in IL, ST, Location has the format:N1Otherwise, if ModuleName is in FBD, LD, it becomes:N2$BT:BIDN1 = instruction line numberN2 = network numberBT = block type (operand, function, function block, etc.)BID = block identifier

The Controls BarThis dialog box allows you to better control the working of the graphic trigger window.A detailed description of the function of each control is given in the Graphic trigger window controls section (see 9.6.1.5).The Chart AreaThe Chart area includes six items:

• Plot: area containing the actual plot of the curve of the dragged-in variables.
• Samples to acquire: number of samples to be collected by the graphic trigger window manager.
• Horizontal cursor: cursor identifying a horizontal line. The value of each variable at the intersection with this line is reported in the column horz cursor.
• Blue cursor: cursor identifying a vertical line. The value of each variable at the intersection with this line is reported in the column left cursor.
• Red cursor: same as blue cursor.
• Scroll bar: if the scale of the x-axis is too large to display all the samples in the Plot area, the scroll bar allows you to slide back and forth along the horizontal axis.

The Variables WindowThis lower section of the Debug window is a table consisting of a row for each variable that you have dragged in. Every row has several fields, which are described in detail in the Drag and drop information section.
