■I/O Refreshing
I/O refreshing refers to cyclic data transfers between a preset area of the memory
and an external source. It involves the following refreshing processes.
I/O refreshing is performed without interruption within a single cycle. Furthermore,
I/O refreshing is always performed after program execution.
I/O refreshing can be performed for CP1L/CP1E’s built-in normal I/O and CP-
series expansion (I/O) units at one of the following 3 timings:
• Cyclic refreshing
• Execution by instructions with immediate refresh variation
• Execution by an IORF instruction
●Cyclic Refreshing
I/O refreshing is performed after all instructions in the executable tasks have been
executed.
This is the standard method for I/O refreshing.
