(c) Send/receive ranges when the local module is on the third-tier local station (l1)
1) l1 station writes data into the range of B/W280 to 2BF, and sends them to other
stations.
2) It can receive data written by other stations within the ranges of B/W0 to FF,
B/W200 to 27F, and B/W2C0 to 2FF.
(2) Link refresh of link data
Q series local stations refresh link data using the sequence program. Note that
refresh is not executed when the CPU module is in STOP status.
