6. Evaluation of External I/O Response Cycle (Dependent on CPU Unit's
Cycle Time)
The operating speed (operation cycle) itself of each function block on the
Loop Controller is not related to the CPU Unit's cycle time. However, as the
CPU Unit's I/O memory is accessed during data exchange, for example,
between Analog I/O Units and the Basic I/O Unit, the timing of data ex-
change is greatly influenced by the CPU Unit's cycle time.
The external analog I/O response cycle (equivalent to the I/O response cy-
cle on a general controller) when the Loop Controller is configured as part
