• The auto refresh settings are stored in the intelligent function module
parameters.
The auto refresh settings become valid by turning the power OFF and then ON
or resetting the CPU module after the intelligent function module parameters
are written to the CPU module.
• The auto refresh settings cannot be changed from the sequence program.
However, processing equivalent to auto refresh can be added using the
FROM/TO instruction of the sequence program.
