Changing, Confirming, and Clearing Preset Values for Timers and Counters
Preset values for timers and counters can be changed by selecting Online > Monitor > Monitor, followed by Online > Custom
>
New Custom Monitor on WindLDR for transferring a new value to the FC6A Series MICROSmart RAM as described on
preceding pages. After changing the preset values temporarily, the changes can be written to the user program in the FC6A Series
MICROSmart ROM or cleared from the RAM.
When the power is off, the temporarily changed preset values in the RAM are cleared and the original preset values are loaded.
Confirm the changed preset values to store them in the ROM. The timer/counter preset values can be confirmed only when FC6A
Series MICROSmart is stopped.
To access the PLC Status dialog box from the WindLDR menu bar, select Online > Monitor > Monitor, then Online
> Status.
Data movement when changing a timer/counter preset value
When changing a timer/counter preset value using
Custom Monitor on WindLDR, the new preset value is
written to the FC6A Series MICROSmart RAM. The
user program and preset values in the ROM are not
changed.
Note: The LCD screen and pushbuttons can also be used to
change preset values and confirm changed preset values.
Data movement when confirming changed preset values
When the Confirm button is pressed before pressing
the Clear button, the changed timer/counter preset
values in the FC6A Series MICROSmart RAM are
written to the ROM.
When uploading the user program after confirming,
the user program with changed preset values is
uploaded from the FC6A Series MICROSmart ROM to
WindLDR.
Data movement when clearing changed preset values to restore original values
