15. (A) Application Parameters
15.12 Trace function
*1 The value(s) "0" to the left of the leftmost non-zero value is(are) not shown in the monitor display. For example, if no trace data is in internal RAM,
sampling retry is not performed, no trigger is detected, and trace operation is performed, "1" appears. (not "0001")
• During trace operation, the Trace status (Y40) signal can be output.
To use the Y40 signal, set "40" (positive logic) or "140" (negative logic) in one of Pr.190 to Pr.196 (Output terminal
function selection) to assign function to an output terminal.
NOTE
• Changing the terminal assignment using Pr.190 to Pr.196 (Output terminal function selection) may affect the other
functions. Set parameters after confirming the function of each terminal.
