(b) From the master station (RY) to a CC-Link remote I/O station (output)
The following shows the time it takes for the output of a CC-Link remote I/O station to turn on (off) after a CPU
module device of the master station turns on (off).
For CC-Link, station-based block data assurance is disabled and the asynchronous mode is used.
• CC-Link IE Field Network station-based block data assurance is available.

SM: Sequence scan time of the master station (including the link refresh time of the sending side)
LSf: Link scan time of CC-Link IE Field Network
n2: Value obtained by rounding up the decimal places of (LSf SM)
: Time for data transfer from CC-Link to CC-Link IE Field Network

LSc: Link scan time of CC-Link
Rio: Processing time of a CC-Link remote I/O station ( Manual for the CC-Link remote I/O station used)
