Changing the value in the Set Value Area (SV)
All the 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:
• 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, or the next time the
power is turned ON.
• When the SV value is rewritten, the currently operating counter will continue operating as-is. The EV
value will not be changed until the next time the reset trigger goes from ON to OFF.
• If the power is turned OFF, or the mode is switched from RUN to PROG., the counter status will be
retained.
• The value in the elapsed value area (EV) can be changed in the same way.

Key operations
Example: Change the value of SV100 from K50 to K20.
Steps:
1) Monitor the status of the word data.
2) Search for SV100.
3) Clear the contents of SV100.
4) Write the new value.
Refer to the FP Programmer II Operation Manual for
details.

Use the high-level instruction
F0 (MV)
as described
below in order to change the counter setting according
to the input conditions.
Example: Change the setting from 50 (K50) to 20
(K20) when input X0 goes ON.
Refer to page 158, “
F0 (MV)
16-bit data move” for
details on the high-level instruction
F0 (MV)
.
• For each
CT
instruction, one SV and EV set and one contact C are supported as follows:
• The counter is not reset even if the power is turned OFF, or the mode is changed from RUN to PROG.
Set system register 6 if you need to set the counter non-hold type. Refer to page 232, “2. Table of System
Registers”, for details about system registers.
• When the count trigger and the reset trigger are detected simultaneously, the reset trigger has priority.
