8.8 Changing the Set Value of Timer/Counter During RUN
Method 2: Method using the FP Programmer II
Use the word data monitor function to read the set value area SV of the timer or counter
to be changed, and rewrite the value.
Example of changing the value of SV0 from K30 to K50.
Procedure:
1. Execute word data monitor (OP8).

2. Read SV0.

3. Clear SV0.

4. Write the new changing value.

Method 3: Method using the program (high-level instruction)
To change a set value of timer/counter based on an input condition, use a high-level
instruction as shown below to rewrite the value in the set value area SV of the desired
timer or counter.
Example: Changing the set value to K20 when input R0 turns on
F0 MV, K20, SV3
R1
R0
T3 Y0
TMX 3, K50
When R0 turns on, the timer set value
changes from 5 seconds to 2 seconds.
