Logic analyzer

The logic analyzer is especially suited to help in the machine start-up and for troubleshooting errors and critical situations in signal behavior.

This option is used to analyze the behavior of the logic PLC signals according to a time base and certain trigger conditions set by the user.

Up to 8 signals can be analyzed at the same time. The results are shown using a graphic interface that makes it easy to interpret the data.

10.10.1 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.

3.

Information window

This window provides general information about the trace being shown at the time. It shows the following data:

 The "Trigger" shows the trigger condition defined by the user to draw the trace.

 The "time base" indicates the time base defined by the user and used to show the current trace.

 The "Trace status" indicates the current status of the trace. The texts shown and their meanings are:

Empty

Capturing

There is no calculated trace.

There is a trace in progress.

Complete There is a trace stored.

 The "cursor offset" indicates the distance from the cursor, vertical green line, to the trigger position, vertical red line. It is given in milliseconds.

 The "trigger type" indicates the type of trigger currently selected. The texts shown and their meanings are:

Before

After

Center

Default

The trigger is positioned at the beginning of the trace.

The trigger is positioned at the end of the trace.

The trigger is positioned in the middle of the trace.

When no trigger condition has been specified.

4.

Editing window.

It is the CNC's standard editing window. It is used for all the processes that require data entry.

5.

Message window.

This CNC uses this window to show a warning or error message.
