SL: Local station sequence scan time
(0 when writing buffer memory in the CC-Link)
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 (buffer memory in the CC-Link), the monitoring
time is 10 s, and the number of retries is zero.

1: Round up below the decimal point
2: Time elapsed when retries of a dedicated instruction occur
(2) Local station
This indicates the time from the moment an instruction is issued by the local
station until a response from the master station is received.
