9.10.1 Description of the work screen
The screen for the logic analyzer is divided into the following areas or display windows:
1. Status window.
It graphically shows the status of each selected signal. It is divided into two areas: Variables area
and status area.
The variables area shows the names or symbols of the logic signals to be analyzed.
The status area shows the status of each variable in square waves. The line for logic level 0 is
shown with a thicker line.
Likewise, it shows a vertical red line to indicate the TRIGGER point and another green vertical
line to indicate the cursor position.
The vertical green line for the cursor may be moved along the trace and helps measure the time
between two points of the trace.
The status area is divided into several vertical stripes. Each stripe represents the amount of time
defined by the "time base" constant.
The "time base" constant sets the resolution of the logic signals and, after being set by the user,
may be modified as often as desired. The "time base" is inversely proportional to the resolution
of the signals; thus, the lower the "time base" the greater the signal resolution and vice versa.
2. Cycles window
This window shows several vertical lines "¦". Each one indicates the instant when the execution
of a new cycle of the PLC program starts.
It permits maintaining a relationship between the flux of the logic signals and the duration of each
PLC execution cycle.
