"EDIT" softkey
It may be used to edit or modify the trigger condition to capture the data to be analyzed.
Once this option has been selected, the softkeys will change colors and they will appear over white
background showing the information corresponding to the type of editing possible at that point.
It is possible to define any logic expression and it may consist of one or several consultations that
must follow the syntax and rules used in PLC equations.
Example of expressions and trigger instant:
M100 The trigger occurs when M100 = 1.
NOT M100 The trigger occurs when M100 = 0.
CPS R100 EQ 1 The trigger occurs when R100 = 1.
NOT I20 AND I5 The trigger occurs when this expression is true.
No more than 16 flank detecting instructions (DFU and DFD) can be used between all the definitions
of variables and the selected trigger condition.
Pressing the [ESC] key deletes the trigger condition being edited. From this point on, the condition
may be edited again.
Once the trigger has been edited, press [ENTER]. The new edited condition will be shown in the
information window.
If no trigger condition has been specified, the system considers that it is a default trigger and it will
show the message "Trigger type": DEFAULT" in the information window. On the other hand, it is not
be possible to select any of the possible trigger conditions (trigger before, trigger center, trigger
after).
"TRIGGER BEFORE" softkey
The CNC starts capturing data from the moment when the selected trigger condition is met.
Then, once the trace has been executed, the trigger (vertical red line) will be shown at the beginning
of the trace.
"TRIGGER AFTER" softkey
The CNC starts capturing data from the moment when the option to execute the trace is selected.
The trace will be completed when the selected trigger condition is met.
The system will show the trigger (vertical red line) at the end of the trace.
"TRIGGER CENTER" softkey
The CNC starts capturing data from the moment when the option to execute the trace is selected.
Then, once the trace has been executed, the trigger (vertical red line) will be shown in the middle
of the trace.
Selection of the time base
The operator may use this parameter to assign the timeframe to each vertical division.
The size of these divisions, therefore the resolution of these signals will be determined by this time
base. Consequently, the smaller the time base, the greater the signal resolution.
