FUNCTIONS
6.22.2 High speed I/O refresh, high speed buffer transfer
Note75Note76
High speed I/O refresh is a function that updates I/O signals between the I/O and
intelligent function modules and CPU module at interrupt cycle intervals.
High speed buffer transfer is a function that updates data between the intelligent function
module buffer memories and CPU module devices at interrupt cycle intervals.
(1) Setting method
To execute this function, set "High speed interrupt I49 fixed scan interval" shown in
Section 6.22.1, "High speed I/O refresh setting" and "High speed buffer transfer
setting".
