Select the scan timing with which the controller CPU exchanges the I/O data with the EtherNet/IP from High and
Low. The data exchange cycle of the controller CPU and the communication cycle of I/O transmissions are not
synchronized.
High: The I/O data is exchanged at the start of the high-speed scan of the controller CPU.
Low: The I/O data is exchanged at the start of the low-speed scan of the controller CPU.
 The controller CPU updates the input registers at the timing set by I/O Communication Setting: Scan only
when there is a change in the input data of the 263IF-01. For this reason, even if the relevant input registers
are mistakenly overwritten by an application or something else, they will not be updated until the next
change in the input data.
The following diagram shows the data update timing between the MP2000-series Machine Controller and
the EtherNet/IP transmission path.
