When the programmable controller CPU type is L26CPU-BT, the transmission speed is 10 Mbps, the link
scan time is 5 ms, the write points are 20 words (buffer memory in the CC-Link), the monitoring time is 10
s, and the number of retries is zero.
OT + LS  [BC + {(write points + 16) / 16}
= 0.5 + 5  [12 + {(20 + 16) / 16}
= 0.5 + 5  [12 + {3  1.067}] + 0
= 76.505
= 76.5 [ms]
