This method rewrites the value
in the set value area. The
program itself is not rewritten.
Transfers to SV area when mode
changes to RUN mode.
Timer set value
Changing values in the set value area SV
Values in the set value area SV can be changed with the following procedures.
− Method using the programming tool software (FPWIN GR)
− Method using the FP Programmer
II
− Method using the program (high-level instruction)
Operation and cautions after the change
After the change, the timer or counter in operation will continue to run. Operation based
on the changed set value will be started the next time the execution condition changes
from off to on.
With these methods, the value in the set value area SV will change, however, the
program itself will not change. Therefore, when the mode is changed and then set back
to RUN or when the power is turned on, operation will take place as follows:
When a set value in the program is specified by a constant K
The constant K is preset in the set value area SV. After the change, it will no longer be
effective.
When a set value in the program is specified by a set value area number
In the case of a non − hold type timer or counter, 0 is preset in the set value area SV. In the
case of a hold type timer or counter, the value changed by the method on the following
page is preset in the set value area SV.
