Data is stored in the link special registers SW000 to SW001F by the program, and data
is automatically stored in SW0020 to SW01FF. The values in parentheses in the
number column indicate the buffer memory addresses.
When the standby master station is controlling the data link, availability is basically
identical to that of the master station.
When the standby master station is operating as a local station, availability is identical
to that of a local station.
POINT
Do not write data to the area of the No. which does not exist in the link special
register (SW) list.
Writing data to the area of the No. which does not exist in the list may cause
malfunction of the programmable controller system.
The following table lists the link special registers.

Default value: 10 (seconds)
Setting range: 0 to 360 (seconds)
The monitoring time of 360 seconds will be used if a value
outside of the above setting range is specified.
If a value is set in SW000B, time elapsed until error completion of a
dedicated instruction is as follows:
(Number of retries + 1) x Monitoring time
