OT: LCPU dedicated instruction processing time
L02CPU : 0.5 [ms]
L26CPU-BT: 0.5 [ms]
LS: Link scan time (refer to Appendix 4.1.)

WT: Monitoring time set in SW0009 (refer to Appendix 3.2.)
RT: Number of retries set in SW000B (refer to Appendix 3.2.)
(Example) 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, the monitoring time is 10 s, and the number of
retries is zero.
