Changing the value in the Set Value Area (SV)
All control units can change the value in the set value area (SV), even during RUN mode, using the high-level
instruction
F0 (MV)
or the programming tool (FP Programmer II or NPST-GR).
The range of values that can be specified in the set value area (SV) are:
C14 and C16 series: SV0 to SV127
C24, C40, C56, and C72 series: SV0 to SV143
• High-level Instruction F0 (MV):
• FP Programmer II:
• NPST-GR Software:
Select [MONITOR LIST RELAYS] in the on-line menu, read the relevant SV, and rewrite.
Refer to the NPST-GR Software Ver. 3 Manual for details.
Notes:
• Example:
Note:
• Note that the timers are non-retentive. They will all be reset (set to 0) if the power is turned OFF, or the
mode is changed from RUN to PROG. Set system register 6 to retain the run status.

When fine-tuning the timing during trial operation, you
can change the values of the special data registers
DT9040 to DT9043, in the 0 to 255 range, using the
potentiometers on the front of the main unit.
R9010: Always ON relay
DT9040: Manual dial-set register for V0.
• Even if the SV value is changed, the setting in the program will not be rewritten. The setting from the
program is sent to the SV and changed only when the mode is changed back to RUN mode, or the
next time the power is turned ON.
• When the SV value is rewritten, the currently operating timer will continue operating as-is. The EV
value will not be changed until the next input ON condition.
• The value in elapsed value area EV can be changed in the same way.

Key operations
Example: Change the value of SV0 from K50 to K20.
Steps:
1) Monitor the status of the word data.
2) Search for SV0.
3) Clear the contents of SV0.
4) Write the new value.
Refer to the FP Programmer II Operation Manual for
details.

Use the high-level instruction
F0 (MV)
as described
on the right in order to change the timer setting
according to the input conditions.
Example: Change the setting from 5 seconds to 2
seconds when input X0 goes ON.
Refer to page 158, “
F0 (MV) 16-bit data move”
for
details on the high-level instruction
