8. DEBUGGING FUNCTION

The times set in "9. ( ) Auxilliary Setting" in the parameter mode are displayed

here.

1) "Program"

The program names are displayed here in the order that the parameters are

set.

2) "Exec"

The types of the programs set in the parameters are displayed here.

3) "Scan Time"

The actual scan times (current values) are displayed here. In the program

stop (stand-by) status, 0.000ms is displayed as the scan time.

4) "Ex Times"

The number of execution times is displayed here, taking the point at which

measurement was started to be 0 in the count (When reaching the maximum

times of 65536, the count returns to 0). The number of execution times is

retained even when program execution is stopped.

When the subroutine program/interrupt program of the stand-by program is

performed in the subroutine call/interrupt request, the number of the stand-by

program is not counted.

(3) Both start ( ) and stop ( ) of the program can be performed on Program

monitor list screen.

(a) Start of program ( )

Either "Scan execution" or "Low-speed execution" can be set for the stand-by

program.

When the key is pressed, the window below is displayed.

(b) Stop of program ( )

1) When the stop mode is set to "Output stop after stop" and stop is executed,

the program stops after execution of 1 scan-off. (The operation is the same

as the POFF instruction execution.)

When the above stop opearation is made in the stand-by program, the

program stops after 1 scan-off execution.

Therefore, the "execution count" is added by one.

2) If an error occurs with the RET/IRET instruction during 1 scan OFF execution

in the stand-by program, the "execution count" is added by one.

In this case, the execution type becomes "Scan execution".
